My air switch always trips on rainy days! Jump when you open it, ask all the masters to find the rea

This phenomenon indicates that one of your appliances or wiring in your home is leaking. On rainy days, the air is humid, and the line will leak and cause tripping where the line is damaged. You can first distinguish whether it is the electrical appliance or the wiring problem.

Distinguish the way, when tripping in rainy days, pull off all the small air openings, and then push on the leakage protector to see if you jump, and then push a small air opening after five minutes, so that one by one try down, and the main gate will jump again when you try to the route with problems. This way you'll find out which route is bad. The next step is to pull off all the other small empty openings, unplug all the electrical appliances on the route with the problem, and then close the main gate to see if it jumps.

If you want to find which electrical appliances, they are also plugged in one by one, and when you see which one is plugged in, which one is the problem.

If there is a short circuit in the circuit of your home, you need to check one side carefully, and some of the ones in the wall should also be checked by shaking the meter to find out the short circuit. The place where the short circuit is not very serious, and when the water vapor in the air is relatively large, the resistance of the air is small, so it is broken and tripped. In dry air it is better some.

This is a safety hazard and must be found.

It may be caused by a short circuit somewhere on the line, so please do so when this happens.

Disconnect (unplug) all outlets and appliances first

Then close the air switch, plug in the socket and electrical appliances one by one, and check until the switch is off, you can judge the fault point.

Leakage protection, don't worry, you can change a switch, they answered better, don't want me.

There are two types of switch tripping, one is empty tripping, and the other is leakage protector tripping.

Air-open tripping, air-open refers to the air switch circuit breaker, which plays the role of over-current, overload, over-voltage, and under-voltage protection in the circuit. When the load is short-circuited and the load is too heavy, the circuit breaker will jump open and disconnect the power supply of the rear stage to prevent damage to the electrical appliances and the danger of line overload.

Another reason is that the load current is greater than the rated current of the air open, in this case, the overloaded electrical appliances can be relieved, or replaced with a larger air open, and the circuit can be restored to normal. When the circuit has a leakage short circuit and other faults occur and there is an empty trip, it is necessary to disconnect or close each electrical equipment, and use the elimination method to find out the fault location.

Leakage protector tripping, leakage refers to the leakage of the live wire in the line, this situation is prone to personal safety accidents, leakage protection tripping is characterized by the leakage protection switch of the "leakage indicator" button pops up, if it is found that the "leakage indication" button pops up, it means that the circuit electrical equipment has leakage, the leakage fault should be eliminated first, and then the "leakage indication" button is pressed, close the switch, and no longer trip.

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.

The leakage protector tripped. Leakage refers to the leakage of the live wire in the line, which is prone to personal safety accidents. The leakage protection trip is characterized by the "leakage indicator" button of the leakage protection switch popping up.

In another case, if you can't find the fault and don't replace the new switch, it may be that the internal contacts of the switch are overheated and ablated for a long time, and the contact is poor, and the replacement can be restored to normal.

The principle of the switch switch at home:

1) In the air opening, if the current is too large, the heating element will produce a lot of heat, and then the bimetal sheet will be deformed by heating, so as to promote the separation of the lock and achieve the purpose of cutting off the power supply;

2) If the line is overcurrent, the electromagnet will also act, and then cut off the power supply.

This is obviously caused by the damage of the wire, it can be changed in this way, 1. The fire zero line of the empty opening mouth is reversed, and the fire wire leakage has now become the zero line leakage, and the iron wire pipe is the ground wire It does not matter. 2. Fire zero leakage, you can use the ground wire as the fire wire, and the other two become the zero wire and the ground wire, and then change the socket to the left zero right fire after the transformation is successful, and the fire wire inlet light switch. 3. If you change the air to open, it is not good to change the leakage to the air without leakage.

1.There is a short circuit on the secondary side of the power supply2The air switch is damp or has a malfunction inside.

1.It is necessary to check from the secondary side of the empty opening to see if there is a short circuit or broken skin.

2. You can use the elimination method to add an electrical appliance in the empty opening, if it does not jump, it means that there is a short circuit on the secondary side, or leakage.

Be safe!

If it's a leakage air switch, that's where the wiring in your house has leakage. Then you can replace the leakage air switch with a regular air switch.

Let's get a new air switch first! Try it!

First all the electrical appliances are turned off, and then turn on one by one, to see which one trips when it is on, it may be that the electrical appliance is leaking or overloaded, my family has tried a similar tripping situation, once is the water heater exhaust pipe into the water, once is the air conditioner external capacitor is broken.

Specifically, check what the rated current of the empty opening is, and it is best to find a clamp ammeter card to see what the current is?

What kind of appliances are the air switches that always trip? If there is no high-power electrical appliance used and it is not current, it is caused by line failure or loose heating of the empty terminal.

Hope it helps!

1. Trip immediately, usually a short circuit fault or empty opening damage. It can be disassembled to open the empty wiring, push the brake to detect whether the empty open is damaged, if it does not jump, it is usually a short circuit fault of the line, it is recommended to use a multimeter resistance file to detect the line.

2. It will trip after a while, usually for overload protection. Touch the appearance of the empty open with your hand to see if it will heat up, if the heat is severe, it is the overload protection caused by the virtual connection of the circuit. Just use a screwdriver to tighten the wiring.

The tripping caused by slight heating is caused by the mismatch between the empty opening and the load, and the empty opening is replaced with the same matching load. It is recommended to measure the circuit with a clamp ammeter.

The empty opening is broken, just change the empty opening.

1. The current setting value of the air switch is too low, and the power of the load is greater than the rated power of the air switch. For example, the switch setting value of the cabinet air conditioning circuit and the electric water heater circuit should be 20A, instead of 16A for the general circuit (the same is true for high-power bath bombs).

2. The joint of the load is not very firm, and some of the electrical appliances that pass through manual wiring are not compressed.

3. If there is a short circuit in the line, check whether the electrical plug is dry.

4. The line is aging and leaking, resulting in electricity in both the live wire and the neutral line, you can check the leakage protector, if it jumps, it means that the electrical appliance is leaking.

There are powerful appliances at home. In this case, it is necessary to check it comprehensively, and the power of the electrical appliances at home is overloaded.

This is a leakage protection device. If there is leakage on the line, it will automatically trip and the power can be turned off.

The reason why the air switch in your home trips on a rainy day.

The air switch trips, excluding the quality of the air switch itself, there is only one reason to cause tripping, that is, overcurrent. When it rains, you always trip, and you need to see if some circuits at home are short-circuited, or that some electrical appliances are overloaded in the afternoon. Plainly speaking, there are only two reasons for the empty tripping:

Short circuit (overcurrent), overload.

The air switch is a very important electrical appliance in the low-voltage distribution network and the power drive system, which integrates control and a variety of protection functions. In addition to completing the contact and breaking circuits, it can also protect the circuits or electrical equipment from short circuits, serious overloads and undervoltages.

The main function of the air opening used in our home is short circuit and overload, when there is a short circuit in the home and the use of high-power electrical appliances will trip. Frequent tripping on rainy days may be due to the aging of the line at home, poor contact of the wire end, and short circuit caused by socket leakage (especially the external wall that is easy to be wet) and cause tripping, which must be checked by an electrician to completely solve the problem.

In addition, if it rains and thunders, it often encounters tripping, one is the air opening at home in the case of thunder, and there will be a malfunction when the air is disturbed by the magnetic field, and the other is that the power supply line of the power supply department may be tripped.

Does your main switch come with leak protection? In rainy days, the air humidity is high, and some electrical appliances (especially air conditioners, etc.) are prone to slight leakage or increase the distributed capacitance, which is easy to cause leakage tripping, and there is no need to use leakage protection when using a reliable grounding wire switch, and the leakage protection switch can be used locally (such as toilets), and human beings have been using electricity safely for more than 100 years in the era of no leakage protection.

There is no doubt that this is after the rain, some places are connected, resulting in overpower and short circuit caused by tripping, check whether the line is damaged, or whether the switch has poor contact.

What is the reason why a switch is always adjusted? This is for sure, it may be rainy and wet, you may not have installed your ground wire, the socket of the switch and the grounding wire, various fireproof and power-off facilities, not installed, you want to be able to check the window head of this switch.

If the line is damp, the household appliance may have leakage, or the leakage switch load is too small

It is estimated that the wiring in the wall is damaged, and the wall is damp on rainy days, resulting in leakage, find an electrician to check it.

Indicate where there is leakage.

Ordinary leakage switches can be divided into two categories, electronic and electromagnetic. The difference between the two is that the voltage of the electronic zero sequence transformer should be electronically amplified and compared, and then drive the shunt trip coil to trip, while the electromagnetic type does not need to go through the electronic circuit to directly drive the trip mechanism to trip, which seems simpler, but in fact it is more difficult to do a good job, and it is also the reason why the electromagnetic leakage switch is expensive.

The starting current of the motor is 4 7 times the rated current, so what is the short-circuit current? And what should be the lightning current? So far, the world's developed countries have not succeeded in experiments to collect lightning, but Japan is the most advanced in this area, and there are no reports of success.

In fact, the current various lightning protection and grounding measures in China only play a role in alleviating the situation, but cannot achieve complete protection.

Your situation can be that the main switch with leakage protection, a rain, monochrome strip screen circuit grounding, the current of the two wires is unbalanced, will trip the main switch due to leakage protection action, (this action current is milliampere, very sensitive) The solution is to install a leakage protection switch on each branch, and install an ordinary switch on the main switch, which circuit has a problem to stop which branch, the main switch only does short-circuit protection and overload protection, so that the power outage area will not be expanded.

The answer should be that the main switch is equipped with leakage protection, when it rains, the monochrome strip screen circuit is grounded, and the current of the two wires is unbalanced, and the main switch will trip due to the leakage protection action, and the action current is milliampere, which is very sensitive.

The solution is to install a leakage protection switch on each branch, install an ordinary switch on the main switch, which circuit has a problem to stop which branch, the main switch only does short-circuit protection and overload protection, so that the power outage area will not be expanded.

I know, because I have this experience: the main switch will jump automatically, and if the switch is pushed up, it will come down by itself, and it will not be able to push up. This is line leakage. It is recommended to check the wiring, otherwise it will burn the electrical appliances after a long time.

Most of the junction boxes are waterproof, pay attention to check. Do a good job of waterproofing the wire. The switch is put into the box for protection.

Obviously, water accumulates inside the monochrome screen, causing short circuits or leakage.
