Sometimes there is a power outage at home, and you need to open the electric switch and close it aga

There are two possibilities for this situation: first, the long-term consumption of large electricity and the absence of demagnetization for a long time leads to the formation of a certain amount of electromagnetism due to a long time; The second is that the bumper inside the electric switch is broken, resulting in tripping.

This happens because today's electric brakes are electromagnetically tripped. Its advantage is that it solves the trouble of changing the fuse and is more sensitive, and the disadvantage is that it needs to be degaussed regularly, otherwise it will cause the magnetic gate to jump by itself due to the long-term current, and the construction will affect the use if there is a little problem inside. Workaround:

If it's the first case, just demagnetize once a month, and there is a square button on the switch, just press it. If it is the second case, it is that the trip bumper is broken, and a small square is connected to the switch, and the contact in it is not real, causing the current to trip if the current is slightly larger or trip for a little longer, and the solution can only be to replace it with a new one.

However, the second possibility is relatively large, because the switch is not off the power, such as the bumper contact is not real, closed in the open can make the contact point slightly better, it is best to find time to change one, and change one to allow more power Because it is usually not a quality problem but a large power often jumps or the switch lever has something to block, forcibly tripped.

If there is a poor contact between the entrance line and the electric switch, tighten it where it should be fastened, and it should be fine.

If the external wiring of the electric switch is not in good contact, it is necessary to replace the electric switch or cut off the power to tighten the external wiring.

It's because of the fault with your home's electric switch, maybe it's aging, let's get a new one.

Either the voltage is unstable in the area where you live, and there will be a sudden power outage when the electricity is intensive.

There may be a problem with the electric switch, so it is better to call a professional to see if it is safe, it is not safe to make it yourself.

You should call someone from the telecommunications bureau to take a look at it for you.

If the leakage protection switch is used, there is a small button next to it, and it can be pushed up only after each trip, if it is not pressed in, it cannot be pushed;

If one or more of the household appliances in the home are short-circuited, it will also cause the electric switch to trip and then not be able to push it. First of all, remove all the electrical plugs, and then push the gate up, and plug in the household appliances in turn.

Circuit overload caused by tripping, the power of the switch, generally look at the rated current marked on the switch can be calculated, such as 16A switch, the maximum power is 16 times 220 is equal to 3520, the maximum electrical power is 3520 watts. If the rated current of the switch is 32A, the maximum power can be 32 times 220 equals 7040 watts. The rated current of the electric switch should match the thickness of the power cord diameter (the maximum safe current of the power cord);

The quality of the switch itself, in the case of ensuring that it is not other problems that cause tripping, it is recommended to change to a first-class switch;

Pay attention to safety, if simple measures still do not work, it is recommended to ask the door personnel to repair it.

There have been three times recently, after a power outage, after a call, there is none.

The main switch is generally the next one to the switch box, and it is generally the largest one. Just break it off and turn off all the power in the room.

What is Switch? Electric switch, generally refers to a relatively large power switch, also known as a switch. It is a switching device that is mainly used for "isolating power supply, reverse operation, connecting and cutting off small current circuits", and has no arc extinguishing function.

When the switch is in a different position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; A switchgear that can carry the current under normal circuit conditions and the current under abnormal conditions within a specified period of time when in close position. The switch switch is the simplest type of low-voltage manually operated switching appliance, and is often used in circuits that are not operated frequently. In order to automatically shut off the circuit in the event of a short circuit or overload, a switch is usually used in series with a fuse.

Under normal circumstances, the first switch on the left side of the switch box is the main switch; If you can't confirm the main switch, you can turn off all the switches in the switch box, so you don't have to worry.

Your house is not far from the entrance door, and there is a distribution box on the wall that can be clamed, and when you open it, turn the biggest switch in the opposite direction. The whole house is out of power, that's right.

The fuse is blown out, just replace it.

First, if you jump as soon as the power is transmitted, first see if there is a newly modified line. Start here to see if you have the wrong line or accidentally hit the line inside the wall while hitting the nail. Generally, the situation of connecting the wrong wire is: the zero live wire is borrowed between the two leakage switches, resulting in tripping.

Second, look at whether it is a total gate jump or a open gate jump. It's easy to get started with a clear ** jump.

Third, if it is a main switch trip, turn off all the shunt switches before powering. If it is still jumping, please check whether there is a short circuit or leakage on the main line entrance line. Check the leakage current and apply the shake meter, which cannot be detected by the general multimeter. If it's okay, try changing it to a leakage protector.

Fourth, in the case of opening tripping, first unplug all the household appliances controlled by the relevant opening control, and turn off the switches of the lamps and lanterns (it may be tripped caused by the leakage of household appliances or lamps.) If it is, please repair the relevant appliances. If it can't be powered, please check whether the socket is burned out.

Finally, check whether there is leakage in the line and replace the leakage protector.

Molded case circuit breaker.

Circuit short-circuit or overload.

Overcurrent trippers.

Action. Not reset.

Or the on-road switch jump is not closed.

Pay attention to safety during operation, judge clearly, and it is best to operate safely under the supervision of someone.

You can also contact the maintenance staff of the property.

The general standard community is one meter per household, and it is a smart meter, which can remotely limit power to you in case of arrears. After paying the fee, you can remotely close and send power. If you want to go out for a long time, the main electric gate at home must be turned off, otherwise it will not be safe.

As for so off gives you two options: 1Find the smart meter box in front of your house and turn off the air switch inside.

2.If you don't pay the electricity bill, let the power grid company remotely turn off the power for you. (It is not cost-effective to pay a late fee for arrears).

If you want to turn it off, it's actually very simple, if you turn on all the electrical appliances at home, you will naturally turn them off, and it's very safe.

How to turn off the main switch at home and which one is the main switch? In short, the main switch switch is in the corridor sub-corridor. You can pull him down as well.

It's the one at the door. Just pull the switch down and you're good to go.

The main switch for general users is at the door, which is marked on it.

Find the meter box and take a picture to show me.

Isn't it broken when the refrigerator is turned off, and the monitoring can't be used?

1. Check whether the inlet end of the wire connecting the air switch from the control socket circuit to each socket is not in good contact, such as whether the connecting wire end between the air switch and the socket is falling off and oxidizing, and whether the connecting screw of the thread is tightened.

2. If you check whether the air switch has tripped, if there is a trip, there may be circuit overload or short circuit. So first unplug the many electrical appliances in the house, try to close the air switch, if it jumps, it means that the line has a short circuit, if it does not jump, it means that the line is overloaded or some household appliances are short-circuited, or even leakage.

3. Use a pen to detect the socket first, if the 2 empty neon bubbles are lit, it means that the zero line is broken, and if the 2 empty neon bubbles are not lit, the live wire is broken. If you are not familiar with this kind of circuit, do not mess around with it, it is recommended to find an electrician to wiring it.

After tripping at home, close the gate again, and there will be no power! What's going on, please?

Hello, pro reasons are as follows1It is very likely that there is a problem with the switch, which causes there to be no electricity after closing. At this time, the main valve needs to be closed, the old switch is removed, and a new one is replaced.

2.If the shrapnel of the switch does not come into contact with the contact of the incoming call, it will also cause no power, try to pull the switch down, and then push it up again, which is generally fine. 3.

There may also be a problem with the line, at this time the maintenance is more troublesome, you need to contact the professional maintenance personnel in time to be responsible for repair, to ensure adequate safety. 4.If the internal fuse is blown out, the fuse can no longer be used, and a new fuse needs to be replaced. �n

The air switch usually has one in the house and one in the installation. You can go to one of the units.

1. Most of the strokes are short-circuited. The air switch usually has one in the house and one in the installation. You can go to one of the units.

But you have to find where the home circuit is short-circuited. Usually, the air switch in the home is separated. You first have to turn off this short circuit and push it on.

A room without lighting is a place for short circuits. You can then find the location of the short circuit on that line, fix it, and finally push the switch all the way down.

2, If you should press the square button first and then turn it off, your house may be a leakage switch.

3. There is a small button on the leakage switch to see if it can be pushed up, if it still doesn't work, it may be a short circuit or leakage.

1. Open some electrical appliances with large power consumption at home and trip, in this case, the load of the air switch is generally small, and the large air switch can be replaced.

2. There is also a situation that the insulation of electrical appliances is generally declining, and the leakage protector is too sensitive, so the leakage protector is generally replaced with an air switch.

3. In addition, because the heavy load exceeds the rated load, it belongs to the overload protection tripping.
