How to vikonate the modernization of the electrical panel at a private booth
Irrespective of those that the normative rules for the operation of electrical installations in residential booths have long been changed in the rural space, as before, it was changed to a lot of booths, as they were powered by the old TN-C circuit through an electric shield with induction zabіzhniks. fusible inserts. Such a scheme will require modernization for a long time.
Navit reconstruction of damaged lines, which should be carried out by electropostal organization, and replacement of old wires on a self-supporting insulated model, do not start the replacement of electrical circuits.
Old electric shields are working at the borders of their capacities, and they are not able to provide the electrical safety of the bagmen.
In order to implement the modernization of the electrical panel into a private booth, it is necessary to take into account a number of factors:
a system of zastosovuvannoy schemes of grounding electrical control and the presence of a bliskvkozakhist, which determines the design of the entry building;
type and function of the electric chiller;
choose the need for protection;
vrahuvat razmіri.
Before the beginning of modernization, it is necessary to take into account the feasibility of all electrical appliances, to sum up and analyze them, in order to create a small margin of tension. Sadiba can be vikonana as a single-surface, so it is a rich-surface life with a different number of arrivals, provided with all kinds of electrical equipment and accessories. All the electricians are to blame, but they are overprotected, and the vanity that is saved by them is protected.
Selection of the entrance rozpodіlchogo annex (VRU) for a private booth - it’s a big topic, in a way, you can change the type of wiring, its construction and the structure of the wires, ways to split the PEN-conductor, which are only used by the ASU, and low other factors.

Protipozhne ELV
Appointed Zahistu explains yoga name. Tse means that in case of unacceptable accidents, damage to the insulation caused a struma of turns to the ground before the appearance, which is a “watchful” ELV and a change in the voltage of the electrical control circuit, forgetting the fault. For this purpose, choose the place of installation in the time after the lichnik for the cooling of the whole zone of the booth, and the setting for the spratsovuvannya 300 miliamperes is assigned.
Voltage level control relay
Regardless of when you come in to increase the reliability of electricity supply, the quality of electricity does not always comply with the declared standards. There is no insurance.
Attachment of zahisnogo inklyuchennya, scho control of a large number of working survivors, can often spratsovuvat. It is not necessary to troubleshoot the malfunction and maintenance of the circuit. ELVs are connected sequentially with the automatic switch, so that the nominal stream is selected according to the machine’s aim, equal to the number of steps greater than the total stream of protection.
The diagram shows that the phase conductor after the ELV is subdivided through linear automatic switches of type B or C and is directed to the downstream without a middle.
The working zero N is not passed through the automation. For a group of patients No. 2 of indications, the option of adopting a zero bus N for an additional auxiliary terminal block.
The group of supporters No. 3 demonstrates the scheme for choosing a difavtomat. Here automatic wimicach is not needed. However, difavtomat in case of inaccurate selection can be pardoned when the pulse blocks of life, for example, a computer, are turned on.
The distribution of the PE-conductor is carried out through a specially formed bus-PE.
Basic power to the electrical panel
The choice of the switchboard model can be modified after the completion of the project of the electric circuit of the booth with the improvement of the total assignment of the number of switching and switching devices. In the event of this, create a small supply for possible connections to the possible additional power, for example, electric pumps, driving gates or emergency lighting.
Ring out, the place in the middle of the shield with an hour will be promptly zapovnyuєtsya and sometimes the masters will deliver an additional electrical panel.
Raztashuvannya shield under the hour of modernization of the scheme following the selection of the improvement of the security of the yogo operation and the spring voltage relief of the scheme of the booth. If there are no plans to replace the electrical wiring, a new electrical panel will be installed after dismantling for changing the installation work.
Access of children, domestic creatures and third-party devices to the shield must be enclosed with a lock, which is locked with a key, which is taken from a specially introduced mist.
Modern electric shields can be used in the middle of a DIN rail, on which all the possessions are securely fastened. Tsim good for the place.
On the doors of the shield in front of the electric switch, manually open a window with a clear insert for reading the reading without opening the lock.
All possessions of the shield must be clearly signed. It is not recommended to use ink, felt-tip pens, or powders for the printer for this coloring ink. The writings may be saved for a long time.
Often, with a compact distribution of switching devices, there is no space for tags. In this way, it is allowed to mark the possession of clearly visible numbers from the folding of the deciphering of the report and the name of the recognition on the okremy arch, which is taken on the doors or to another accessible place.
Correctly marking and reporting descriptions of the warehouse elements of the shield in the future shore at a rich hour, nerves and help to fix faults in the merezhi.
Take the safety shield in the middle of the safety poster “Don't get in! Work on the line! help when repairing the circuit to turn off the power of people under the voltage. The poster should always be hung on the vimknenі important automatic machines at the hour of vikonanny, be it robots.
Features of installation in the electrical panel
Mounting of automatic devices on a DIN-rail is mounted in such a way that the arc-extinguishing chamber (grid, plates) is known to the beast (important inclusion of directing uphill). With such an expansion, the most friendly mode of arc opening is created when it is turned on, which saves the resource of the robot by approximately 25%. Incorrect placement of the machine will shorten the term of its operation.
The introduction of life to the automatic machines is directed to the beast, and the introduction of advancement is from below. Okremi virobniki, for example, Siemens or Legrand allow you to serve food enough. But in the electrical panel, everything can be switched on one-way - otherwise, in the process of robotic electricians, it is possible to pardon and induce attacks against electrical injuries.
When connected in parallel in one row of devices, mounted on DIN-rails, insulate a separate comb and special entry clamps.
Insert the pins of the comber at the zatyskach of the machine. It is entered by a clamp with its own shtirk to wind up here. To turn off the peroxide of the comb, the pins of the clamps are placed under the pin of the comb on machines with a lower, rumpled part of the seal. If there is no fluffy part, then the stitch of the glue is spread over the stitch of the comb. Wires are connected to the entry terminal.
Vykoristannya rozpodіlnyh combs not є obov'yazkovoy vymogoy. Bagato mastrіv robyt installation with flexible wires, squeezing their ends with special tips. Such a scheme comes out as a whole work, but it takes a little time, and in heaps of wires it is easy to understand.
For the connection of the neutral zero PE, a special earth bus is installed, it is laid out near the introduction of the main cable mass. For all types of placement in the shield of the phase bus L and operating zero N, it is necessary to insulate the case for them.
The incoming cables of electric power start at the shield through the top or side mounting openings, and the live cables from the bottom. Mustache cables and wires are responsible for clear marking and identification. Thought out and neatly designed cabling to save space in the electrical panel and allow electricians to easily deal with the installation of the circuit in the process of operation.
Before the introduction of the robot after the completion of the installation, before connecting to the voltage, it is necessary to carry out an external and internal inspection of the installed property and to conduct a measurement of the insulation support of the selected circuit.
The new shield needs to be serviced. For this, through the operation, it is necessary to carry out a control stretching of all threaded connections and contacts, and then recheck them once again. І don't forget to check the ELV with the "Test" button if you want.
