I turned on all six air conditioners in the house, why didn t they trip yet

Tripping is a self-protection mechanism for household appliances, and always tripping means that your air conditioner is out of order. The reasons why the air conditioner trips as soon as it is turned on are as follows: there is a short circuit inside the air conditioner, and the electric switch jumps quickly after it is turned on to play a protective role.

The current of the air conditioner is greater than the rated current of the electric switch, so after turning on the air conditioner, the electric switch quickly trips and plays a protective role. When the power switch fails, resulting in the power switch not reaching the rated current of the power switch, the power switch will trip. Workaround:

Replace the power switch. If it still trips, it is an air conditioner failure. You need to contact the after-sales service of the air conditioner for repair.

No matter what electrical appliances are, if there is a trip, there are many reasons, but look at your trip caused by leakage, find a multimeter to measure the resistance to the ground should be greater than 0 5m ohms, if a few thousand ohms below to see if there is water in that place, measure whether the shell of the outer machine is charged, the insulation is not good or the cable has a touch of the casing, and the door-to-door fee for repairing the air conditioner is also 50. Let's find someone to repair it as soon as possible.

Poor contact. Some air conditioners are installed on the wall, while others are pressed on the ground, and if the air conditioner is installed on the wall, it will require a long wire. At this time, if the length of the wire is not enough, it will affect the fit between the plug and the socket.

If the plug and socket are not together, the air conditioner will always trip.

If it is an air conditioner placed on the ground, pay attention to whether there are children at home, if the child accidentally kicks the air conditioner wire while walking or running. At this time, the air conditioner will also trip suddenly, which will also affect the safety of the child.

Could the main cause be a problem with the current? There may be a cause of electricity leakage behind the air conditioner. Or the current passing through the air conditioner is greater than the air conditioner itself.

So when the air conditioner can't withstand the current. The air conditioner is more likely to trip. What happens when the air conditioner trips?

How can I prevent my air conditioner from tripping all the time? To ensure the size of the current. Also pay attention to the plug and socket, be sure to connect together.

1. The air conditioner refrigerates the inside of the home and trips in less than 2 seconds as soon as the air conditioner is turned on.

2. After moving the main switch up again, turn on the air conditioner and refrigerate for about 2 minutes before it trips.

3. And the fan of the external unit does not rotate when the air conditioner is cooling.

4. Turn on the air conditioner and the air supply mode does not trip.

Like, but the fan does not turn either.

5. Because I shared a house with someone else, I heard the person who shared the house say that in the past, the three air conditioners in the house were turned on together, and they would not trip.

6. There are three air conditioners (hanging type) and one refrigerator at home.

7. The other two rooms will not trip if the air conditioner is turned on at the same time. Only my room will trip the air conditioner when it is turned on alone.

8. When the weather was not very hot the previous week, I drove it once, and it wouldn't trip, but the sound of the case outside was very loud.

9. The model of the leakage current is: AJR 40. Leakage i n= . 28014.The teachers took the trouble to help me see what the problem was, the weather was too hot.

Broken gates? Leakage and empty opening "statutory" testing once a month!

Non-intelligent qualified air opening, leakage insurance, it is recommended to replace it without failure for 3 years, because when it is broken, it will not call the police, in case of a personal accident during the period, there will be no play!

One day last year, 3 years after the new home, I accidentally accidentally electrocuted when operating the electricity at home, but the leakage warranty did not occur, and after further inspection, it was found that the leakage warranty of the qualified products in the power box failed, and there were also individual empty failures! The 40-year-old electrician himself was amazed!

Immediately, the leakage and empty opening of the whole family were all replaced!

You check whether the rated current of the air opening is too large.

Maybe it's the reason why the power of your air conditioner is not big, it's a good thing not to trip, do you still want to trip?

There are ghosts at home, so you don't need to ask!

After tripping at home, the reasons why the air conditioner cannot be turned on and the corresponding solutions are as follows:

1. Poor installation. The lead wires of each pile head are not firmly connected and loose for a long time, which will cause heat in the pile hair.

Oxidation, burn out the outer insulation of the wire, and emit sparks and burnt smell, resulting in undervoltage of the line and air switching.

action, just reconfigure the line.

2. Leakage switch.

quality issues, with loads.

Mismatch. The actual electrical load of the household is greater than the rated current of the low-voltage circuit breaker on the line. It generally occurs after the new installation or new use of high-power household appliances such as air conditioners and electric water heaters. The matching air switch must be replaced.

3. Leakage and short circuit of electrical appliances or lines. When it is found that the electrical appliances used are leaking, as long as you unplug the electrical appliances with leakage faults, and then close the low-voltage circuit breaker again, you can send electricity. If a leakage or short circuit is found in the line, an electrician must be called to deal with it.

4. The incoming voltage of the power supply is too high. This is very dangerous and generally occurs in the "three-phase four-wire system."

Powered residential hugs. At this time, see if both wires are electrified; Second, see if the left and right neighbors also trip; Three-purpose multimeter.

Measure the incoming line voltage. Do not forcibly close the low-voltage circuit breaker, otherwise it will burn out the electrical appliances at least and cause a fire at worst.

Explanation of tripping:

The safe operation of the traction power supply system that supplies power to the electric locomotive should be ensured. In the event of an accident, it is installed in the traction substation (opening and closing station.

The relay protection device in the partition booth is activated by the short-circuit current generated by the accident.

Automatically disconnect the circuit breaker that supplies power to the accident point to reduce the scope of the accident and ensure the safe operation of other equipment and the normal power supply to the non-accident line. This action of automatically disconnecting the circuit breaker due to an accident is customarily called "tripping".

First of all, it is necessary to rule out what is the cause of the trip, whether it is the cause of the air conditioner or not, whether it is overloaded with the total load, or whether there is a short circuit, and then whether there is leakage, etc. If it is not caused by the air conditioning problem, it is usually normal, and it cannot be turned on after a power failure, it is estimated that the air conditioning insurance is burned, and a good one can solve the problem.

After tripping in the house, the air conditioner cannot be turned on. It is possible that the power outage caused by a sudden power outage may cause the machine to get stuck. You can. Unplug the power supply and start anew.

It may be that there are too many people who use electricity at night, and it is easy to trip if the voltage is unstable, and it will not trip when the voltage is stable.

The total power supply valve at home tripped, it may be overload protection, and the air conditioner cannot be turned on after closing, indicating that the air conditioner fuse is burned, or there is a problem with the power supply module.

Air switch, we all know that in addition to its own on-off function, there are three protection functions are overload protection, short-circuit protection, over-under-voltage protection, and the above three faults will trip;

1.First of all, the short circuit is ruled out, because if the short circuit trips, the brake cannot be closed, and it is impossible to use it for a period of time and then trip.

2.It is also possible to rule out overvoltage or undervoltage, because we have installed an overvoltage and undervoltage protector.

3.So in the end it's overloaded; Combined with the situation when tripping, the air switch is a little hot after tripping, which is the most typical manifestation of overload, so the problem is overload.

The main switch is only 40A, when the sum of the current of these four circuits is greater than 40A, it will cause the main switch to trip, and the rated current of any main switch cannot be greater than or equal to the sum of the rated current of each circuit switch - generally only larger than a branch switch with the largest rated current.

If this happens, it may be that one of the appliances in the home is grounded, or the largest switch will trip due to the excessive load of the appliances in the home.

In this case, first of all, there is a problem with household electricity, generally a problem with the leakage switch; The reason why the air conditioner trips is that the current of the air conditioner host is unstable and causes tripping. If there is a problem with the leakage switch of household electricity, the air conditioner will trip if it is not turned on, and the current will flow through the leakage switch after the air conditioner is turned on, so that there will be a tripping situation. You can do a professional test on the leakage switch, or you can replace the leakage switch.

However, replacing the leakage switch needs to be replaced by a professional electrician, and it is important not to replace it privately, which is prone to safety accidents. The problem of the main engine of the air conditioner, as soon as the refrigeration is run, the internal will be short-circuited, generating high-voltage current, resulting in tripping. Prolonged use makes the air conditioner trip at high temperatures.

Check whether the neutral wire and grounding wire are reversed or accidentally touched when replacing the compressor; Check again that the model of the compressor is the same as before. To solve this situation, you need to purchase a voltage regulator to stabilize the input power of the air conditioner at a certain value, so that the voltage of the air conditioner will not fluctuate too much when it is turned on, and there will be no tripping. Many friends have encountered the phenomenon of air conditioner tripping, we need to understand the principle and cause of tripping, and take corresponding measures to promote the normal use of our air conditioner.

It is recommended that households with air conditioners should set up a special power supply to basically prevent the air conditioner from tripping.

If the home trips when two air conditioners are turned on at the same time, it could be due to one of several reasons:

1.Overload:

Two air conditioners running at the same time consume a large amount of electricity. If your circuit is undersized and guessed to carry such a large load, it can cause the circuit to be overloaded, triggering fuse or circuit breaker trip protection.

Solution: Make sure your circuit capacity can support running two air conditioners at the same time. If you need to increase the circuit capacity, consult a professional electrician for installation and adjustment.

2.Short Circuit:

When the air conditioner is running, if a short circuit occurs in the circuit, it can also cause the circuit breaker to trip.

Solution: Potato shed oak: Check the air conditioner power cord and plug for signs of damage or short circuit. If any problems are found, they should be replaced or repaired immediately.
