Such applications are called vologous. Classification of the place behind the stage of unsafe electric shock

Bezpeka robots with electrical installations to lay a lot of things. The head of the most important officials is the mind of the working process. The presence of the presence in the atmosphere of various houses in the atmosphere of various houses: a saw, gas, superfluous water negatively affects the quality of work and the safety of people. It also increases the efficiency of the robot and high temperatures (the workshops are too thin).

Іsnuє nebezpeka razhennya electric jet

All manufacturing workshops, located in any presence of electrical installations, behind the stage of an emergency with an electric jet, are seen in the group: Group 1 (workshops without advanced anxiety), unsafe accommodation).

Group I - workshops without advanced security

Characteristic:

• the work is carried out at normal temperatures up to +5 degrees and the moisture content up to 75% (according to the rules for the construction of electrical installations (PUE);
• Pokrittya prepared and non-conductive materials: tiles, wood, linoleum and similar;
• a minimum of electrical installations that provide grounding;
• daily folding metal structures;
• near the surface, there is no streak-providing saw on the surfaces;
• for such applications are typical large squares that low coefficient of space filling;
• it is allowed to work with electric devices with a voltage of 0.23 kV.

Zone without increased security for personnel

Apply: office premises, dispatcher rooms, utility rooms, billing equipment centers, administrative offices and caring equipment.

ІІ group - admission with advanced insecurity

Characteristic:

• The temperature of vibration is higher than 30 degrees (vіdpovіdno up to PUE).
• The material for the preparation of underlayment covers, as a rule, is streum-conducting: earth, concrete, metal. For the presence of vologists on the surface.
• High water content repeat (more than 75%).
• For such applications, haircuts are allowed (until I become rich) or betting.
• At the place of use there is a collection of a strum-providing saw: on walls, underlays, cables, equipment.
• The coefficient of filling the area over 20%.

Gorishche - a place with an unsafe electric shock

For the presence of one of the overexposure factors, the application is included up to 2 groups (valid up to PUE).

Apply: service areas for transport facilities, non-flushing hills and hills, accommodation for heating and thermal robots, repair shops, coal mines toshcho.

ІІІ group - especially unsafe accommodation

Characteristic:

• increased water content again (close to 100%);
• presence of condensate on the surfaces of fixtures, underlays, walls;
• the presence of liquid gases, vapors, as well as the destruction of the insulating sheath of electrical cables and cables;
• the presence of flowers.

Also, up to the ІІІ group, zones are introduced, if you want to have 2 signs from the front category.

Apply: smelting shops of metallurgical plants, facilities for naphthochemical industry, factories for processing syrovin, chambers for washing, battery storage, storage facilities especially unsafe materials, combustible speeches and others.

Especially for the purpose of the (workshop) - tі, the water content of those during the virobnicheskom process reaches 100%.

Placement (workshop) with a streak-guiding saw - zones in some hours of work accumulate streum-conducting saws (steel mills, metal processing workshops). Presentation slip factor lowering the power of the insulation curves of electrical installations and supporting the body of a person.

Spectacular zones (premises) are characterized by virobic processes that occur at high temperatures. Razrіznyayut hot (30...35 °С) and especially hot (with the temperature of the working process higher than 35 °С).

Workshops with caustic vapors (aerosols). In this group, one can see a variety of uses, among others there are gaseous sums and vapors that destroy the shells of possession. In such zones, additional insulation should be installed on top of electrical installations.

Fire-insecure accommodation. To tsієї categorії vіdnositsya virobnіchiі shops іn teritoryії, in іkіmіvії that іѕ аbоutly аbоrіgаyutsya easy syrovina (betting, zrіdzhenі gasi, rіdini, drank, ready virobi).

Vibuho-unsafe workshops (applications) are called such, in which they are established, or they save up for the hour of producing vibuho-unsafe speech, zgidno s PUE. The butt is the maydanchiks of oil refineries, enterprises of the military industry.

Vіdkritі maidanchik pіdpriyemstv, on yakimuyuyutsya electrical installations, zgіdno s PUE, expanding klasifіkatsіy primіschen z elektrobezpeki. The zone can be as open as it is closed. The peace of people's defense against the electric shock and the life of the fence.

Peace for the protection of people - a sign for staff ahead of time

Please come in:

• the level of danger of damage by electric jet is reduced by vibration effective system ventilation;
• the quality of the cover, the materials prepared play a key role in the security of electrical safety;
• for virobnitstv, de іsnuє mozhlivіst viniknennya static elektrika, pіdlogі vokrittya z dielectric vikoristovuvaty fenced;
• in case of vikonannі work in areas of increased nezabezpeka personnel need to be protected by protection, recognizing the given voltage, for which the electrical installation is being operated.

Classification of applications for electrical safety

Electrical applications are called occupants or vagrants, for example, nets, parts of the occupancy, accessible to less qualified service personnel, de-installation of electrical installations.

Dry applications are called applications, in which the water content is more visible in 60%.

Water applications are called applications, in some pariahs, condensing water is seen only for a short time in small numbers, and the water content is visible more than 60%, but it exceeds 75%.

By Sirim's Admissions they are called applications, in some of them the water content is often more than 75%.

especially sirimi accommodating they are called places, in which the water content is often close to 100% (stele, walls, underlay and objects that are in the place, covered with water).

Spectacular applications they are called applications, in some cases, in the case of thermal infusions, the temperature rises constantly or periodically (more than 1 dobi) + 35 ° C (for example, applications from dryers, drying ovens and scorching ovens, boiler rooms).

Sawed by apparitions they are called places, in some of the minds of the minds of people, there are technological saws in such a large number, that wines can settle on darts, penetrate into the middle of cars, equipment, too thin.

Pilov's applications are subdivided into applications with a stream-conducting saw that is used with a non-conductive saw.

Application with chemically active or organic medium they are called places, in which it is constant or during the last three hours, aggressive wagers, gasses, ridins settle down, or bloom, which destroys the insulation and strum-conducting parts of the electric field.

For a non-safe vibe, or else, the appli- cations become vibuho-non-safe (six classes - B-I, B-Ia, c, d, B-II and B-IIa) and fire-safe (chotiri class - P-I, P-II, P-IIIa, P-III).

Electrical installations beyond the minds of electrical safety can be divided into installations up to 1000V and installations higher than 1000V, inactive and inactive.

It is not safe to injure people with an electric jet to fight:

Admittance without increased anxiety , In some days, think about what they are doing promotion or especially trouble.

Admission with increased insecurity I don’t know that they are characterized by the presence of one of the advancing minds that they create promotion of insecurity:

a) the water content of either a streak-providing saw (visible water content overrides 75%);

b) streum-conducting pidlogs (metal, earthen, concrete, cast-glass);

c) high temperature (more than 35◦С);

d) the feasibility of a one-hour dotik of a person to metal structures, technologic devices, mechanisms, which can only be built from the ground, from one side, and to metal buildings of electric power - from the other side.

3. Especially unsafe accommodation , which are characterized by the presence of one of the advancing minds, which create a special problem:

a) especially high viscosity;

b) chemically active organic medium;

c) at once two or more minds of increased anxiety.

4. Territory of distribution of ovnіshnіh electrical installations. When people are unsafely injured by an electric jet on the territory, they are equated to especially unsafe places.

Particularly unsafe accommodation:

especially volume

chemically active or organic medium

one hour 2 or more minds of increased insecurity

Appointment without advanced insecurity - daily mind of advanced insecurity

Siri application - vіdnosna vologіst vshe 75%

Especially siri application - vіdnosna vologіst is close to 100%

Hot room - the temperature is constant or periodically (more hot) exceeds 35°C

Saw application - technological saws are seen behind the minds of virobnitstva.

Adopted with a chemically active or organic medium - either for a long time or for a long time, aggressive paris, gas, homeland, settle down, bloom.

Electrical security, grounding, grounding, switching on. Zahisne grounding.

Navmisne z'ednannya іz the ground those other constructive, metal parts of the electrically controlled, which normally do not lie under the pressure, but they can lean under the tensile force with a rippled z'єdnanny with the stream-guided parts. The head of the zahisnogo grounding - the usunennia of the unsafe defense of the struma of the people at the dot to the hull, which leaned against the pressure.

The area of ​​zastosuvannya zakhisnogo grounding of a three-phase lifeline up to 1000 st. from the isolated central.

The principle of dії zahisnogo grounding - znyattya naprugi between the body, scho leaning under the naprugoyu, and to a safe value. So the difference is well grounded and without struma will be about 150 times.

Grounding extensions tse sukupnіst zemlyuvacha - metal conductors. Grounding workers are piece and natural. Grounding conductors are made from sheet steel.

Posladnannya p_dlyagaє grounding - ce metal non-conductive metal parts of the electrical control, with which, in the case of moving, or especially unsafe, the grounding of the installation is higher than 12 volts of a replacement or 110 volts of a direct stream.

Zeroing

Zanulennyam sound advancing to a non-singly grounded zero dart the living quarters of the buildings and other metal parts are electrically controlled, as if they are not normally under pressure.

Zavdannya grounding is just like a zahisnogo grounding.

Zeroing principle --transformation of a breakdown to the case in a single-phase short circuit (tobto a flicker between the phase and the neutral wire) with the method of viklikati a great strum, the building's safety of spratsovuvannya zakhistu, tobto. turn on the installations in the living area. Such a zahist є: swimming zapobіzhniki, automatic.

The area of ​​zastosuvannya zanulennya: three-phase chotir wire lines up to 1000 st. from a deafly grounded neutral.

Zahisni Zasobi

Zahisnі zasobi can be divided into three groups: insulating, protecting, protecting.

Isolating - Take care of the isolation of people from the strum parts, as well as from the ground. Іsolyuyuchi zahisnі zasobi be divided on the main and addendums.

Main insulation features- zdatnі tripaliy hour vitrimuvat working voltage (up to 1000 st - gum gloves, tools with insulated handles).

Dodatkovі insulating properties- Up to 1000 Art. dielectric galoshes, kilimki.

Gardening - Timchas fence-shields, portable grounding.

Western - zahisnі eyepieces, protigazi, zapobіzhnі belts.

Grounding and zahisnі come in electrical safety

Terminology

Deep earthed neutral- the neutral of the transformer or the generator, is brought directly to the grounding outbuilding.

Insulated neutral- the neutral of the transformer or the generator, as it was not brought to the grounding outbuilding, or it was brought to the new one through the great opir.

neutral- the central point of the windings (elements) of possession in the mirror.

Grounding extension- supply of grounding conductors and grounding conductors.

grounding machine- a conductive part, or a combination of con- ductive parts connected to each other, which are in electrical contact with the ground

As natural grounding can vikoristovuvatisya:

metal and reinforced concrete structures are the life and spores that are found near the ground

metal pipes for water pipes, laid near the ground

battens of main non-electrified rails

metal structures, or speculate what is in the ground

metal sheaths of armored cables laid near the ground.

Piece grounding devices can be made from black or galvanized steel or midi. Pieces of grounding are not guilty of mother zabarvlennya.

Zahisne grounding- grounding depends on the method of electrical safety.

Zahisniy zanulennya

At the fences from the dead-earthed neutral, the most effective zahisne vanishing.

Zahisniy zanulennya- navmisne z'ednannya vіdkritih strumoprovіdnyh parts z deaf-earthed neutral in the meshes triphasic struma abo with deaf-earthed visions of dzherel in merezhs single-phase strumu, which is dependent on the method of electrical safety

The principle of dії is the transformation of the signal to the case on a single-phase. short chirp With the method of calling the great strum of a short hum, building security for the strum protection and, by the same time, automatically turn on the optional setting for the live strum.

Vidkrita conductive part- the part of the electrical installation is accessible to the dot, which normally does not change under the voltage, but it can be under the voltage if the main insulation is weak.

Direct dotik- dotik from strumous parts

Indirect dotik- dotik іz vіdkritimi provіdnimi parts, scho opilis under naprugou with poor insulation.

Come in whenever you need electrical safety to lie down in the place where the electrical installation is installed, according to the nature of the place. For recognition, there are special applications for electrical installations and the application of other recognition (production, service, service, trade, etc.).

Applications for electrical installations- tse akі primіschennya аbо vіdgorozhenі part іnіn_іshchennya, in which elektroobladnannya is installed and available only for a special warehouse, which may require qualifications.

Applications with electrical installations are characterized, as a rule, by minds, which are cooled in normal, increased temperature, moisture content and a large amount of metal possession obtained from the earth. Everything is created by the unsafe electric shock. An offensive classification of applications has been introduced: dry, water, sir, especially sir, hot and powdered.

Dry applications naming the application, in which the water content is more visible in 60%.

Water applications naming applications, in some cases, that condensing water is seen only for a short time in small numbers, and the water content is more than 60%, but does not exceed 75%.

By Sirim's Admissions naming an application, in some of them the water content is often more than 75%.

Especially with orphans to name an application, in which the water content is often close to 100% (steles, walls, underlays and objects that are in the application, covered with water).

Spectacular applications naming an application, in some cases, in the case of various thermal changes, the temperature rises constantly or periodically (more doby) 35 ° С.

Sawed by apparitions name the place, in which the minds of people see technological saws in such a large number that they can settle on the wires, penetrate the middle of the machines, the devices too thin. The saw application is divided into the application with a jet saw and the application with a non-conductive saw. In addition, different applications are made with a chemically active or organic medium, either for a long time or for a long time, aggressive vapors, gasses, radiants settle down, or a splash, which destroys the isolation of that stream-providing part.

Healthy signs, the application is subdivided into three groups behind the stage.

Admittance without increased anxiety, In some days, think about what they are doing promotion or especially trouble.

Admission from the promoted insecurity, Yaki is characterized by an idea of ​​the onacculations, Scho Scho to fade a fucked carelessness: Vukkostі Abo-Stroprodnaya Saw, Streamoprian Pіdlog (Methali, Earthy, Svisobetonnye, Ceglessness), Vococe Teteraturi, Mozdlosti Single Mobile People to Metal Constructions, Scho Majutz earth budіvel, technological devices, mechanisms, from one side, that to the metal buildings of electric power - from the other side.

Especially unsafe accommodation, as they are characterized by the presence of one of the advancing minds, which create a particular insecurity: a particularly viscous, chemically active chi of an organic medium, at once two or more minds of an increased insecurity.

When the security of a special warehouse is damaged by an electric strum, the territory of the location of the outermost electrical installations is equated to a particularly unsafe location.

Come in whenever you need electrical safety to lie down in the place where the electrical installation is installed, according to the nature of the place. In these articles, we can look at the methods classification application for electrical safety.

For their recognition, they are divided into: specialization in electrical installations and other applications (production, production, service, trade, etc.).

Applications for electrical installations - tse akі primіshchennya аbo vіdgorozhenі part іnіn_іshchennya, in which elektroobladnannya is installed and available only for a special warehouse, scho may nebhіdnu qualіfіkatsіyu i permit for the maintenance of electrical installations. Applications with electrical installations are characterized, as a rule, by minds, which are cooled in normal, increased temperature, moisture content and a large amount of metal possession obtained from the earth. Everything is created by the unsafe electric shock.

The Rules for the construction of electrical installations (PUE) have the following classification: dry, watery, siri, especially syrі, hot and powdered.

Dry Applications are called applications, in those who have a visible water content, they do not exceed 60%.

Vologimi applications are called applications, in some parities that condensing water is seen only for a short time in small numbers, and the water content is visible more than 60%, but not exceeding 75%.

Sirimi applica- tions are called applica- tions , in those who have a visible water content, it often exceeds 75%.

especially sirimi occupants are called occupancies, in which the water content is often close to 100% (steles, walls, underlays and objects that are in the occupancy, covered with water).

Spekotnimi prismіshchennyami namіvіshchennya, in some pіd vplіv rіznіh thermal vіpromіnyuvan temperature perevishuє stіyno аbo periodically (more doby) 35°С.

Pilnimi applications are called applications, in which, behind the minds of people, there are technological saws in such a large number that the wines can settle on the wires, penetrate the middle of the machines, the devices are too thin. The saw application is divided into the application with a jet saw and the application with a non-conductive saw.
