How to operate and recover after the air switch trips

At home, right? A small blue protrusion in the lower left or middle of the distribution box.

Press it. Then just push the tripped one back.

In addition, you need to determine if the location of the short circuit has been dealt with.

Some large empty openings are moved down hard first, and when they hear a click, they move up and reset.

There is no load in the home circuit, empty tripping, the first thing that can be excluded is the trip caused by overload, because when the empty trip, the electrical appliances are not opened, so it is impossible to overload, let's just rule out the overload first.

Second, let's look at the short circuit, after all the circuits have a short circuit, do not troubleshoot the short circuit. And if it is restored, the air switch cannot be closed, and the short circuit will not occur when the river air at home trips in a few minutes to dozens of minutes after opening and closing, such a frequent situation.

Therefore, the air opening at home trips after a few minutes to dozens of minutes after closing, and the reason may be undervoltage or overvoltage.

In addition, there is a possible reason that the inside of our air switch is damaged, and another point is that the air switch or the wiring in the circuit is not in good contact, both of which may cause the above conditions to occur.

The solution of tripping a few minutes to tens of minutes after the air switch is closed.

The first point is to check the wiring of the empty opening and the lower opening of the empty opening, if you can't check the problem of the empty opening. Yes, you can replace a new air switch and it still trips, then all the circuit wiring at the lower port of the air switch at home must be carefully checked to ensure that they are well wired.

The second point is that it is best to install an undervoltage protector at home, which is the commonly used self-resetting overvoltage and undervoltage protector, which can play a certain role in protecting our voltage fluctuations to avoid damage to household appliances.

A trip switch means that the line may be short-circuited or leaking, so we first check each household appliance for faults, and then check each terminal board for temperature rise or burning. If you can't find out, you can unplug all the plugs in the house, plug them in one by one, and see which plug will trip, that's the problem. Once you've figured out the appropriate plug problem, you can fix it.

When the fault here is dealt with, go back and press the small square on the right side of the air switch, and then close the switch of the electric switch, you can successfully solve the problem of still no power after tripping. However, Bian Xiao would like to remind everyone here that tripping circuit maintenance is dangerous. Non-professionals are not allowed to operate without permission.

If there is no electricity after the trip, a professional electrician from the property or maintenance company can come to the door**.

Circuit breakers (another name for household switches, also known as "null switches") are very clever and have internal protections designed to prevent the switch from burning out – when the switch burns out, it automatically closes and locks. This design is designed to prevent burned-out switches from disconnecting, leading to the danger of power consumption. Generally, the black marks left by the burnout can be seen from the surface of the burned out circuit breaker, which generally appears at the position of the binding post.

But it is not excluded that some circuit breakers are hot-fried, and the traces are hidden inside, and they cannot be seen from the outside. We can try to replace the circuit breaker, but don't forget to check the fault after replacing the circuit breaker: many times, the circuit breaker just burns out because of the end of its life.

In this case, it can be solved by replacing the circuit breaker. In some cases, after a fault such as a short circuit or lightning strike, the circuit breaker burns out. At this time, we need to install lightning protection devices on the road and check the short-circuit fault points before we can continue to use them.

1. In this kind of protection situation, the first time is to cut off all the power supply of the household electric elevator, after cutting off the power supply, on the one hand, it protects the household appliances, and on the other hand, it can also effectively eliminate the load end problem.

2. If the undervoltage protector still has a protection signal after cutting off all the power supplies of household appliances, then the voltage should be measured with a multimeter. The measured voltage is normal, but the protector is still flashing, that is the problem of this under-voltage protector, and replacing a new under-voltage protector can be used normally.

3. If Nianshan cuts off the voltage at the load end, there is no flashing signal in the protector, which means that there is a fault at the load end, and it is relatively troublesome to check, and it is necessary to use a point-to-point method.

4. In the last case, the above situation is that the incoming voltage is high or low, so it should be repaired in time to eliminate the problem that the voltage of the whole building or the entire line deviates from the normal value. Because the flashing lamp in this under-voltage protector is a protective lamp, but there is no indication of under-voltage or high voltage, so this flashing signal can only prompt that the voltage value is not within a reasonable range, and if you want to determine whether it is high voltage or low voltage, you can only use a multimeter to measure the voltage of the incoming line, if it is found that it deviates from the normal value, it means that the air switch protector is not damaged and bent, but the problem of the upper voltage entering the household. If it is a problem of the upper voltage entering the household, it is necessary to contact a professional property electrician or call the power supply company to report for repair, and do not force the power on to avoid damage to household appliances.

There are basically three situations when the air switch trips, the first is short circuit, the second is leakage, and the third is overload.

You can turn off the sub-switches first, and then you should be able to push the main switch (you can't push it is basically the main switch is broken), and then the sub-switches are closed one by one, and the main switch trips when you close the sub-switch, so you can know which route there is a problem, and then check the electrical appliances on this switch, or unplug some electrical plugs to see if there is a problem. This kind of problem is generally caused by sockets or lights, or it is caused by household appliances.

If your air switch is protected from leakage, then it may be caused by leakage in the electrical shell.

If your air switch is tripped for a period of time, then the possibility of overload is very large, first touch the shell, whether you feel the heat, and then you can turn on a few less appliances to see if it will trip, the best way is to use a current clamp to measure the current of the load connected to the air switch, if the actual current is greater than the rated value of the air switch, then it must be overload tripping.

Try to reset first and then start, if the second time is still tripping, then find out the real cause of tripping, eliminate the fault and then close. It is estimated that the dust in front of the pants is either leakage, Hu Chan tripping, or overcurrent tripping. You can first remove the electrical equipment to judge the scope of the fault, and gradually narrow it down to the point of regret on a certain equipment.

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.

5. If you make sure that the wiring and electrical appliances at home are normal, it may be that the quality of the air switch itself is not up to par.

What is the air switch?

1. The air switch is also called the air circuit breaker, as long as the current in the circuit exceeds the specified current, the air switch will automatically disconnect the switch. The function of the air switch is to protect the circuit from burning out due to excessive current. Because air is used as the medium for arc extinguishing, it is called an air switch.

2. In the principle of air switch, the overload current can not make the electromagnetic tripper move, but it can increase the heat of the thermal element, and then let the bimetal sheet bend upwards and push the lever to disconnect the buckle and the lock, and then the main contact is segmented, and finally the power supply is disconnected. The tripping mechanism is a complete linkage that locks the main contact in the closing position when it is closed by the operating mechanism. In the event of a circuit failure, the relevant tripper will disengage the latch in the contact mechanism and then break under the main contact, which will eventually start the protective role.

3. The models of air switches on the market are generally uppercase letters and numbers, which mean something. Which model should I choose for household electric air switch? Before choosing the model of the air switch, we first have to figure out what these numbers and letters represent.

Generally speaking, there are only two types of air switches on the market: C and D. C stands for trip current and D stands for power. It may be abstract to say this, but let's take an example to understand the model of the air opening and taking the Huiguan.

The model of an air switch is: DZ47 60C20, where DZ stands for automatic, 47 stands for its design serial number, so DZ47 stands for its miniature circuit breaker. 60 represents the frame is equal to 60A, and C represents the instantaneous tripping overcurrent multiple of its tripper.
