What is the reason for the short circuit of the wire, the empty open, the tripping, and the power ou

The air switch is too big, and the wire will not trip if it burns.

An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects whenever the current in the circuit exceeds the rated current. 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.

Under normal conditions, the armature of the overcurrent tripper is released; In the event of a serious overload or short-circuit fault, the coil connected in series with the main circuit will generate a strong electromagnetic attraction to attract the armature down and jack the locking hook, so that the main contact is disconnected. The undervoltage tripper works on the contrary, when the voltage is normal, the electromagnetic suction pulls the armature and the main contact is closed.

In the event of a severe voltage drop or power failure, the armature is released and the main contact is disconnected. When the power supply voltage returns to normal, it must be re-closed before it can work, and the voltage loss protection is realized.

It may be that the current setting value of the empty opening is too low, or some electrical appliances are manually wired and the joints are not compressed. Ordinary switches generally do not have overvoltage or undervoltage protection, but will only pass through overcurrent or several sections of protection, such as fuses, only in the case of excessive current will trip and power off, and the trip time is generally determined by the size of the current.

Power off The reason why the air switch does not trip: the rated action current of the air switch is too large, and the maximum allowable current of the line does not match, and when the line is overloaded or partially burned for a long time, there is no short circuit or the air switch action current value is not reached, so it does not operate.

The air switch does not have the function of leakage protection, so if the wire is not burned due to short circuit or overload, the air opening will not act in advance (including the combustion process is not short-circuited), and the quality of the air switch is a problem.

Solution: You should check the line and electrical appliances first, there is a small blue twist on the panel of the general leakage protection, it will bounce up when the leakage protection action, press it back first, and then close the switch.

Another thing to pay special attention to is that if it is a trip caused by electrical overload, we must first power off the relevant electrical appliances so that they can be restored.

This is normal! When for some reason the empty open tripped. The empty internal tripping is cut off, and the power supply is cut off, and the handle must be pulled down to close again, and the handle must be pressed down and closed again to close. That's what design is all about.

The contacts inside the switch are not in good contact, so let's change it.

There may be an overload in the air opening, so it is best to replace it with a larger one in the air opening.

Agree with the second floor, the contact contact is not good, when it is closed and then closed, it is very likely that the contact will be connected, and the third floor is talking about the operation method of the leakage switch.

There is a problem with the switch, so it's best to replace it.

Abstract The reason why the air switch does not trip: the rated action current of the air switch is too large, and the maximum allowable current of the line does not match, and when the line is overloaded or partially burned for a long time, there is no short circuit or the air switch action current value is not reached, so the power failure is caused by non-action.

What is the reason why the air switch does not trip and loses power.

The reason why the air switch does not trip: the rated action current of the air switch is too large, and the maximum allowable current of the line does not match, and when the line is overloaded or partially burned for a long time, there is no short circuit or the air switch action current value is not reached, so the power failure is caused by non-action.

This situation is generally due to the excessive use of household appliances, resulting in excessive air opening power load and non-tripping power failure.

There is an option to replace the high-power air opener.

Hello dear, the air switch does not trip and the power loss may be caused by the following reasons:1The overload protection settings are not reasonable:

The air switch has an overload protection function, which trips the air switch and loses power when the load current exceeds its rated value. However, if the overload protection is not set properly or is turned off, the air switch will not trip even if the current is overloaded. 2.

Aging of air switches: With the extension of time and the increase of the number of uses, the internal parts and contacts of the air switch are easy to age, damage or stick, which affects its overload protection function. In this case, the air switch cannot be tripped even if the load current is overloaded.

3.Poor ground wire contact: If the connection between the ground wire and the equipment is loose or the wire is defective, then the air switch loses effective grounding protection and cannot play its protective role correctly in abnormal situations such as short circuits.

4.External environmental influences: environmental factors such as temperature, humidity, and pollution may also affect the normal operation of the air volt-sensitive switch.

It should be noted that ignoring the problem of the air switch will bring safety hazards to the use and cause serious losses to the equipment production process, so when there is a problem, the air switch needs to be overhauled or replaced as soon as possible.

The air switch does not trip and loses power due to the following reasons:1Overload Protection:

The air switch has an overload protection function, and when the circuit load exceeds the rated current, the air switch will trip and lose power. However, if the circuit load does not exceed the rated current, the air switch will not trip and de-energize. 2.

Short-circuit protection: The air switch also has a short-circuit protection function, when the circuit is short-circuited, the air switch will trip and power off immediately. However, if the circuit is not short-circuited, the air switch will not trip the stool belt.

3.Fault: The air switch itself may also be faulty, making it not work properly.

For example, the contacts inside an air switch may have burned out or have poor contact, causing the switch to detect the state of the circuit and perform a power-down operation. It is necessary to further inspect the circuit to confirm whether the circuit load exceeds the current set by the forehead, whether there are problems such as short circuits, and check whether the air switch is faulty. If the problem cannot be identified, it is recommended to contact a professional electrician for maintenance.

Summary. The short circuit of the wire is caused by excessive current, and it should be the thermal protector of the circuit breaker that plays a role, not a leakage protector. The two are not one type of electrical appliance.

If it is a line ground leakage, the leakage protector will work.

Now it's all in one. If the rated current of the leakage switch is too large, the leakage switch will not trip when the wire is short-circuited.

It is recommended to overhaul it, is it the reason.

Now it's all in one. If the rated current of the leakage switch Zhengzhou is too large, when the wire is short-circuited, the leakage and wide shielding switch will tripped due to leakage.

It is recommended to overhaul it, is this the reason [summary].

Hope it helps.

Please be careful.

1. It is possible that it is not in a sensitive judgment trapped circuit, and there is a phenomenon of wrong installation during installation, these two are separate individuals, and they are not connected to the bridge, so after the short circuit, the empty opening will naturally not jump.

Chongling 2, it may be that the empty open is broken, it is recommended to check it, if it is really broken, then it needs to be replaced with a new one.

3. It may be that the selected staggered air is opened, and the rated current is too large, so if it does not reach this value, it will definitely not jump automatically.
