Electric mites - principles of work

Strumovimiruvaln's pliers are an accessory, the main signs of such a vimiryuvannya of an electric strum without breaking the electric lance and disrupting its functioning.

Dodatkovo tsey prilad zdatny also vimіryuvati naprugu, frequency, temperature (for some models).

Vidpovidno to vymiryuvanih values ​​are subdivided into ammeters, voltmeters, wattmeters, phase meters, ampervoltmeters.

To the widest ones one can see mites ammeters for vimiryuvannya snake strum, which took away the name of strumovimіlavalny mites. With their help, you can quickly cut the strum at the conductor, without opening it or turning on the electric lance. Electric circulators can stagnate in electrical installations up to 10000V.

About the recognition of a lot of electrical accessories and tools, be it any inhabitant - you know everything, now you need a soldering iron or an electric drill. Ale is far from being on the skin, there are mites not on the skin.

Irrespective of the price, the trumpet pliers are recognized for a wide variety, it’s just that someone doesn’t know about the basis of such an attachment and doesn’t care for it.

Where do the electric mites stop?

Strumovimiruvalny mites can become an indispensable helper both for butovyh survivors, and at enterprises of various scales. Three of them can be helped:

• - to determine the actual interest of the merezhі. In order to determine the voltage of a single-phase tie, a fading on the incoming cable is created, and the value of the stream in amperes is multiplied by the voltage in the tie and the cosine cut between the phases (cos φ). If there is a daily reactive bias (suppressed inductive elements, throttles, motors), then the remaining value is equal to one (cos φ = 1).
• - Reducing the tightness of various fittings. In times of need, the strength of the struma of the deer of the lancer with the connection of a companion is reduced. The tension is due to the formula described above.
• - in order to re-verify the functioning of the device, adjusting the shape of the energy savings, for example, changing the readings of the lichilniks from the actual savings.

The design is familiar

To warehouse electric mites whether any modifications include the following main parts: clamp-magnetic conductor, switching ranges and functions, display, external roses, button for fixing the switch. At this article, strum marks are seen matech M266.

The jumper can be installed in one of the modes of switching:

1. - DCV – constant voltage;
2. - ACV - changing voltage;
3. - DCA - constant strum;
4. - ACA - change strum;
5. - Ω – opir;
6. - diode icon - re-verification of diodes;
7. - signal icon - buzzer buzzer.

Three entrances of roses can be used to zahist in the form of overwhelm. When connected, the black wire of the probes is connected to the “COM” socket, and the red one - to the “VΩ” socket. The third rose, meaning EXT, is required for connection to the insulation.

The order of vimiryuvannya strumu

The switch between is restored to the position, as if it confirms the necessary range of vimiryuvannya strum. The current clamps are connected to the switched conductor.

If there is more than a “1” value on the display, it is necessary to jump between the values ​​set to a higher value, so as a winklo changeover.

The order of the voltage reduction

The black wire of the probe should be connected to the “VΩ” socket, the black one - to “COM”. The jumper between the insertion into the position, scho vіdpovіdaє vіmіryuvanomu range.

Feel the probes to get to the vimiryuvannogo navantazhennya or dzherela napruzhenya. On the screen, the device will be careful about the voltage that is being controlled, as well as its polarity. If the screen is afraid of more than the value “1”, then the jumper between it is necessary to switch to a higher value, shards of vinyl vanity.

Order win support

Feel the fit just like that, like when the voltage is vimіrі. Set the range jumper to the range Ω. As an attachment for dialing, it is necessary to install a jumper at the emergency position. As soon as the opir vimiryuvanoy scheme of the circuit is less than 50 ohms, then the buzzer signal will sound.

Electric mites - principles of work

The robot of the simplest strumovimіryuvalnyh klіshіv zminny strum is based on the principle of a single-turn transformer strum.

Yogo primary winding є nothing else, like drіt chi bus, yakіy vimіryuєtsya strum. The secondary winding, which has more turns, is wound on a pink magnetic conductor and is located in the clamps themselves. An ammeter is connected to the secondary winding.

By vibrating the strum, which flows through the secondary winding, by adjusting the visible coefficient of transformation of the vimiruval transformer, you can reduce the amount of strum, which is mitigated in the conductor.

Respectfully, for help strum mites Vimiryuvati strum (and in fact - navantazhennya) in the lancet is not coherent and easy. The process itself is vimir polagaє in the offensive.

Behind the help of the handle there is a value that is being fought. The pliers are roaring, the conductor is let through, the handle is let in and the pliers are muted. The farther order of selection of electric pliers is the same as when prompted by a powerful tester.

You can add ticks to the insulated one, and to the uninsulated one. Naygolovnіshe - only one tire is to blame. On the indicator of the attachment, the size of the struma of the lancet lancet is displayed.

In such a manner, as if to fire the conductor and press the button, after the opening of the magnetic conductor on the screen, the device will be saved and the display of the device will be fixed.

Along the stream-conducting part, as if hemmed in by a magnetic circuit, pass a change stream. At the magnetic circuit, a significant magnetic flux is created, as a result of which electromagnetic induction occurs in the secondary winding - on the second (secondary winding) the strums begin to flow, which is controlled by an ammeter.

Today strum mites follow the scheme, in which the transformer stream and attachment will go. It allows the secondary windings to be connected to the winding outbuilding through a set of shunts, and not without a middle.

How to squirm with strumovimiruval mites

How to make the arrangement of the fence near the apartment?

The changeover range is set to the ACA 200 position. The trumpets are broken, when they are introduced into the apartment, insulate the wires with them, fix the indication that they appeared on the screen of the accessory.

Otriman's value is multiplied by the voltage of the measure 220, the cosine is taken equal to one.

butt. It is permissible, the attachment shows 6A. Tse means that the inventory of the apartment is warehoused:

P \u003d 6 220 \u003d 1320 W \u003d 1.32 kW.

For these data, you can check the correctness of the work of the lichnik of the saved electric power, the validity of the actual input cable input and іn.

A little trick with wimirah

How can you kill a small strum for the help of electric pliers?

In order to die strum mites the strength of the struma is small, it is necessary to conduct, for which it is necessary to know about the strum, to wind a sprat once on the magnetic conductor. Set the distance between the transitions to the minimum value.
