Is a closed door power outage a strong cut or a soft cut?

Closed-door power outage, it is best to cut softly, if it is forcibly cut off, it may cause arcing.

Fire strong cut: The shunt tripper is essentially a splitting coil and tripper. This tripper is also used for thermal and electromagnetic tripping.

Add the specified voltage to the shunt trip coil, and the circuit breaker will trip and open. The shunt tripper is commonly used in the control of long-distance automatic power cut-off, and now the most used is to cut off the non-fire power supply in the fire control room. The circuit breaker can not be closed remotely immediately after the shunt tripping, nor can it be directly closed manually, and the circuit breaker must be deducted again before it can be closed, which is the same as the tripping after overload tripping.

This is the difference between a shunt trip and an electrically operated switch.

There are three positions for the circuit breaker operating handle, except for the well-known two positions of the upper and lower parts, the handle will stay in the middle position after tripping. The so-called re-buckle is to pull the handle from the middle position to the minute position to re-hook the tripper, and then it can be closed.

The voltage types of shunt trip coils are AC and DC, and the voltage size has various voltage levels. When cutting off the non-fire power supply, it is the most convenient and easiest to use the DC24V fire power supply as the shunt trip coil power supply. The shunt trip coil can only be energized for a short time, and it will burn out after a long time; Therefore, in the control loop, the normally closed contact of a circuit breaker should be connected in series, and the current of the shunt trip coil should be cut off after the circuit breaker trips.

The shunt coil is used to trip The closing coil is used to close the closing coil to close all the normally open and all the normally closed After the shunt coil is engaged (tripped) all the normally open is disconnected and all the normally closed is closed.

The normal closed-door power supply is out of power, which is a strong cut, and it is not within the scope of the software.

If the power goes out behind closed doors, it is a strong process, otherwise it will not be able to turn off.

It is more appropriate to cut the power outage in close doors, because at this time, if there is no quick response, it may cause some losses.

When the power supply is cut off behind closed doors, it must be soft-cut.

Such a soft cutting mode can be relatively safe for normal and safe electricity consumption.

We can still force the power outage of the closed-door power supply, and we probably think this should also be necessary.

If you turn off your own power, I suggest that you give him this power supply directly, and after the power outage, it's okay, there is no need to cut your own wire and other products.

If you switch to build the garden, there is that heating, and that strong family cuts that softly, and it's good to master it.

In general, if the power is turned off, then the operation cannot be continued.

This power outage, whether it is to grab money or software, you have to find an engineer, and he will give you the right answer.

The power outage of the laptop, whether it is robbery or soft gas, I feel like it all.

When you don't know how to play, you two need to see the official website of the head teacher now.

If there is a power outage, then you must cut it strongly, and the door cannot be opened if it is not cut strongly.

Is the power outage a strong solution or a remote cut? It should be a strong cut.

Closed-door power outage is a strong cut, which is generally mainly achieved by the function of wall paint.

It is dangerous to forcibly cut in during a power outage when the power supply is closed.

3 core copper wires, one brown or red, one black or green, and one yellow-green wire, for grounding protection.

It is required to use three cores for safety, and the copper core is good.

The power supply of many household appliances has three wires, which are the live wire- (denoted by L).

The neutral wire (denoted by n) and the ground wire (denoted by e) are used for leakage protection.
