Problems with air switch tripping, causes of air switch tripping

It will trip, because the empty load side is already grounded. At this time, the air open is closed, and a single-phase short-circuit circuit is formed between the load side of the air open and the earth, and the protection device (air open) on the line acts quickly to cut off the power supply.

Pure hand-hitting, pure original, forget.

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 being able to complete contact and break circuits, it can also protect circuits or electrical equipment from short circuits, serious overloads and undervoltages, and can also be used to start motors infrequently.

There are three cases when the air switch is always tripped:

First, if the load is too large, you can change the empty opening with a large load.

The second is that there is a problem with the line, there is a line grounded, or the line meets, which needs to be overhauled by professionals.

The third is that there is a problem with the household appliances at home, and one by one to eliminate the problems with that electrical appliances. Satisfied.

Friend, if you disconnect the power supply and can't close the switch, then it's obvious that the air switch is broken. If you are using an air switch instead of a leakage switch, then the leakage of the line will not affect the air switch that cannot be closed.

There should be two reasons: one is that the line is aging, the load is large, or the other is loose, and the other is the small capacity.

It's hot, the electricity consumption is high, the line temperature is high, and your air opening capacity is small, so it will trip as soon as the air conditioner is turned on. You can try to change to a large capacity empty open, and it should be no problem.

Summary. It may be because of the condensation of the air conditioner during operation, which causes the air conditioner to leak, and it is necessary to check the leakage phenomenon of the water flow in the line.

This question is up to me, it takes a little time to type, so please be patient.

There is a short circuit in the line, check whether the electrical plug is dry.

The house renovated a few years ago, in the third year of this year, the main switch of the air conditioner tripped, I don't know why, why?

It may be because of the condensation of the air conditioner during operation, which causes the air conditioner to leak, and it is necessary to check the leakage phenomenon of the water flow in the line.

It can also be changed to energy after the air conditioner has been running for a period of time, the whole line is hidden and the road is heated, and when the heat is larger, the temperature of the air conditioning components is too high, and the air conditioner will overheat protection and trip. It is necessary to avoid overloading the air information change.

Have you been using it for the past few years?

Probably broken recently.

The reasons for the tripping of the air switch are: overload, short circuit, floor leakage, aging of electrical appliances, and air switch failure.

1. Overload. When the electrical load in the circuit exceeds the rated current that the air switch can withstand, the air switch will automatically trip. This usually happens when we use multiple high-power appliances at the same time, such as electric kettles, hair dryers, induction cookers, etc.

In order to avoid overload, we need to plan the use time and power of the appliance reasonably so as not to exceed the load bearing capacity of the air switch.

2. Short circuit. A short circuit is when there is a low-impedance connection between two or more conductors in a circuit, resulting in excessive current. In this case, the air switch will automatically trip to protect the appliance and personal safety.

A short circuit can be caused by a damaged wire, poor plug contact, or an internal fault in the appliance.

3. Ground leakage.

Floor leakage refers to the leakage of electricity between the electrical enclosure and the ground. In this case, the air switch will automatically trip to protect personal safety. Ground leakage can be caused by the failure of the internal insulation of the appliance, the damage to the enclosure of the appliance, or the poor contact of the ground wire.

If there is a floor leakage, stop using the electrical appliance immediately and ask a professional to overhaul it.

4. Aging of electrical appliances.

Aging appliances can also cause air switches to trip. As the appliance grows in use, the components inside the appliance may deteriorate and be damaged, resulting in unstable circuits. In this case, the air switch may automatically trip to protect the appliance and personal safety.

If the appliance is severely aged, it may need to be replaced or repaired.

5. The air switch is faulty.

Finally, the air switch itself can also have a faulty code circle, causing it to trip. Air switch failures can be caused by damage to internal components, poor contact, or mechanical failure, among other reasons. If the air switch fails, stop using the electrical appliance immediately, and ask a professional to overhaul or replace the air switch.

Air switch is a kind of circuit protector, also known as low-voltage circuit breaker, when the circuit exceeds the forehead grinding gear Wang Ding current, the air switch will automatically cut off the circuit, so as to achieve the role of protecting the circuit, as well as protect the safety of household electricity. Nowadays, many homes will choose to install air switches. Air switches will inevitably trip, so what are the reasons for air switches tripping?

Air switch Air switch, also known as automatic switch, low-voltage circuit breaker, etc., is a common circuit protector in home and engineering, when the working current exceeds the rated current, short circuit, loss of voltage, etc., the automatic cut off circuit to achieve the role of protection.

In addition to the protection function, it can also be used with leakage, measurement, electrical operation and other module units, in the low-voltage distribution system, it is often used as a terminal switch or branch switch, replacing the fuse and knife switch commonly used in the past.

The role of the air switch.

1. Current limiting and undervoltage protection: when the wire is short-circuited, a large current will occur, so that the electrical appliances will burn out, and the air switch has this function, when the current is greater than the current of the empty opening, the switch will clutch to achieve the purpose of power failure.

2. Short-circuit protection: After using the air switch for blind boys, when the line is short-circuited and grounded, it will automatically clutch.

3. Overload and overheating protection: Overload is overload, and the heating of the wire leads to the reaction of the electromagnetic coil of the air switch, which makes it clutch.

4. Isolation and interphase protection: Generally, the current below 30mA is normal and acceptable to the human body, and the leakage current will be unsafe if it is higher than this, so the air switch can isolate the leakage current above 30mA within a few minutes of switching and clutching (this value is determined according to the parameters of the air switch).

5. Leakage protection: everyone thinks that the phenomenon of stupid hail leakage can only produce leakage on the earth, and some say that only the total open and inductive switch can react, in fact, this is not complete, and the air switch, single P air open will also react to leakage.

The reason why the air switch tripped.

There are three main reasons why an air switch trips:

One is that the load is too large, in this case, you can change the switch with a larger load.

The second is that there is a problem with the line, the line is grounded, or the line meets, and this situation requires professionals to repair.

The third is that there is a problem with the household appliances at home, which needs to be manually checked one by one which household appliances have problems.

Regarding the problem of air switches, I will introduce so much to you today, I don't know if it has helped you solve the problem. It is recommended that for the safety of household electricity, it is best to install an air switch.

<> "How to look at the air switch model.

The model number of the air switch is usually composed of letters and numbers, such as DZ47-63 is a miniature air switch, DZ is the abbreviation of open circuit breaker, 47 represents the design number of the air switch, 63 indicates the frame level current rating, this compact air switch is used for rated voltages up to 400V, and the main AC power supply used is 50Hz or 60Hz.

The reason why the air switch tripped.

1. Installation error.

If each lead is not installed firmly and loosened for a long time, the lead wire will heat up, the outer insulation of the lead wire will burn, produce sparks and burning smell, and it is easy to undervoltage the line and the air switch trip, so when installing, be sure to wire correctly.

2. The load is not matched.

When the voltage load does not match, the air switch may trip, this problem mainly appears in the air conditioner, electric water heater and other high-power household appliances on the mountain, at this time you need to replace the matching air switch, when you buy it should also be determined according to the power use of your own appliances.

3. Leakage or short circuit of electrical appliances or lines.

If a short circuit is found, pull out the short circuit fault and close the low-voltage circuit breaker again to send power. If a short circuit or short circuit occurs, please let an electrician deal with it, disconnect all the shunts first, and then turn on the power. If one of the circuits is closed and the air switch cannot be closed, it means that the branch is faulty and the branch maintenance is energized.

4. The voltage of the power input line is too high.

This kind of problem is very dangerous. At this time, you can check whether both wires on the line are live, check whether the left and right neighbors have tripped, and then measure the incoming Bikai voltage. Do not force the air switch off. Electrical appliances are easy to burn out, and in severe cases, they will cause disasters.
