The main gate of the unit trips, while the electric switch of the household does not trip

1. That is, the electrical circuit in the household is damaged, when the electricity consumption exceeds a certain value, it exceeds the leakage current value of the resident's circuit breaker, and the household circuit breaker does not have time to trip, and crosses the first-level protection to reach the leakage current value of the unit layer circuit breaker.

2. It is also possible that the total load of each user under the east side of the main gate is too large, and the main gate will trip for a period of time during the operation time under the condition of overload.

3. The performance of the main switch is unstable, and a new switch needs to be replaced.

4. From the phenomenon that the household appliances do not go away, it can be said that there is a phenomenon of electricity theft or that there is a problem with the original installed line.

Extended Materials. Common faults of leakage circuit breakers.

Put into tripping. 1) If the three-phase power line, including the neutral line, does not pass through the zero sequence current transformer in the same direction, the wiring can be corrected.

2) The circuit with the installation of the leakage circuit breaker and the line without the installation of the leakage circuit breaker is electrically connected, and the two circuits can be separated.

3) There is a fire and a ground load in the line, and such a load can be eliminated.

4) There is a phenomenon of repeated grounding on the working zero line through the zero sequence current transformer, and the repeated grounding should be eliminated.

5) The leakage circuit breaker itself is faulty and should be replaced.

Malfunction. 1) Caused by overvoltage. If the circuit breaker can be operated when the operating overvoltage occurs in the line, the leakage circuit breaker with delay or impulse voltage can be selected, and the resistor-capacitance absorption circuit can also be installed between the contacts to suppress the overvoltage, and the overvoltage absorption device can also be cast in the road.

2) Electromagnetic interference. If there is a magnetic device or high-power electrical equipment nearby, the installation position of the residual current circuit breaker should be adjusted to stay away from such electrical components.

3) Improper grounding. If the neutral line is repeatedly grounded, it will cause the malfunction of the leakage circuit breaker.

4) Effect of overload or short circuit. If the leakage circuit breaker has short-circuit protection and over-current protection at the same time, malfunction will occur when the setting current of the overcurrent protection tripper is not suitable, and the setting current value can be adjusted at this time.

There are several reasons why it trips frequently:

1.Residents increased the use of high-power electrical appliances, and the load current exceeded the rated value of the main switch, causing the main switch to trip.

2.In the past, when tripping, the current was too large and burned out the contacts inside the main switch, resulting in poor contact and heating. As a result, the internal thermal protection element of the main switch acts and trips.

Touch the main switch shell in normal use or just tripped, if the temperature is very high, it is the above two reasons. If there is no significant temperature rise, it is leakage or short circuit.

1. Since the opening is the electrical component that controls a single channel, and the main switch is the sum of each channel, when the current or voltage of each road is higher than the setting of the main switch, it may jump.

2. The main switch tripping should generally be a problem with one or several roads, and the failure to trip the shunt may be due to the fact that the controller setting may not match the circuit currently controlled, and it is recommended to check.

Summary. Causes of circuit tripping:

1. Large electrical appliances such as water heaters and air conditioners: For electrical appliances with large power, they must be wired separately during decoration. Otherwise, it will be very easy to trip in later use.

2. Short circuit of load line.

If the load line is short-circuited, it will trip at the moment of power on or the moment of opening the empty opening, that is, it will not be powered at all.

3. The problem of empty opening.

This is the rated load power, and it's a normal C-type circuit breaker (see if the tripped switch has the word "C16"?). What is the maximum power of air conditioner heating? If it is close to or greater than that, it means that the current flowing through the switch is too large during the heating process, and after a few minutes, the switch heats too much heat, and it will automatically trip with a delay.

Why is the unit electric old tripping?

Hello, I am very happy to be here with you, I will find you a problem as soon as possible, please wait patiently, thank you very much, thank you for your understanding. 

Reasons for circuit tripping: 1. Large electrical appliances such as water heaters and air conditioners: For electrical appliances with large power, they must be wired separately during decoration.

Otherwise, it will be very easy to trip in later use. 2. Short circuit of load line. If the load line is short-circuited, it will trip at the moment of turning on or turning on the empty opening, that is, it will not be powered at all.

3. The problem of empty opening. This is the rated load power, and it is an ordinary C-type circuit breaker (look at the trip switch is not respectful of the word "C16"?). What is the maximum power of air conditioner heating?

If it is close or greater, it means that during the heating process, the current flowing through the switch is too large, and after a few minutes, the switch is overheated, and it will automatically trip with a delay.

I'll give you a few of the possibilities first. And then you rule it out.

Summary. What is the reason why the three-phase main gate jumps, but the residents do not jump when the gate is opened? Hello dear, there are three reasons:

1. It may be that because the shunt switch does not have a leakage protection device, when the first road leakage, it will not trip when it is separated, but there is a leakage protection device when the total opening is opened, so when the line is detected to have a leakage fault, it will make a trip action, and it needs to be checked one by one. 2. It may be that the branch switch is not overloaded, but the total power consumption exceeds the rated load of the main switch, so it leads to tripping, and it is recommended to replace the main switch with larger specifications. 3. It may be that there is leakage between the main switch and the load, and it is necessary to ask a professional to investigate.

The main gate is 160A, and the sub-household is 63A, all of which are leakage switches.

Hello dear, first of all, the 63A circuit breaker is not tripped, and the circuit breaker only has a protective effect on overcurrent and short-circuit faults, which can eliminate the overcurrent and short-circuit phenomenon of lines and loads. Secondly, the 160A total leakage protection trips, and the leakage protection is against the leakage current. Single-phase grounding.

Faults such as load defects have a protective effect, which proves that the line or load has a leakage of tung land electricity, or there is a single-phase grounding fault, and the fault current exceeds the protection value of the leakage protection switch, so the 160A leakage protection will trip. Finally, it is recommended that you change the 63A circuit breaker to a leakage protection shunt switch for safety, if the line or load has a leakage or ground fault, the 63A leakage protection will trip, and will not cause the 160A total leakage protection to trip. Pay attention to the safety of operation when dismantling the wheel, and try to ask a professional electrician to change it when necessary, I hope it can help you.

I wish you good health and a happy life!

1. Such a problem is likely to occur because the protection at all levels is not well coordinated, and this problem is now very common, because the protection value in the residents' homes and even the corridor is greater than the protection value on the external power supply line of the power supply company, resulting in a failure, the external response is faster than the inside.

2. This fixed value includes, overload, short circuit, grounding current, source envy value, and time delay. However, after such a problem, the most important thing is not to find out whether there is a problem with these protection cooperation, but to find out the fault point, and if the external line is not found to be a problem, all the subordinate (including all the branch switches in the family) switches and gate knives should be opened, starting from the superior power supply step by step, leaving sufficient intervals in the middle, until the fault reappears, and isolating the lines and electrical appliances after the overhaul here.

Why do you trip at every turn? What are the causes of tripping? Here's what the old electrician had to say.

This situation is bai

Yes, the electric brake is a little small. As soon as the amount of electricity is too much, it will automatically trip. And the DAO is this automatic protection inner device is smaller.

It's so sensitive. You're prone to tripping. Third, the wires are wired.

This situation is also prone to tripping. If you want to change the status quo, change to a larger protector. Withdraw the wiring line.

I think it's because the electricity consumption exceeds the allowable amount of the switch. It can increase the allowable power of the electric switch.

It may be that the line copy road is aging, somewhere leakage, should be paid attention to, bai a small area near our home, du is the intercom door leakage, the property does not pay attention to the dao, the result is a thunderstorm in the summer when the door is wet, worse is the water in front of the door, forming a pond, a junior high school student in the morning to this community to call classmates to go to school together, the result was knocked down by the intercom door leakage of electricity, although the rescue was struggling, but also failed to save the young life! So be sure to pay attention!

There are three reasons:1The line is aging and leaking. 2.Electricity consumption exceeds the rated power. 3.A residential line is connected to electricity.

Electricity always trips generally due to the mismatch between the leakage switch and the load, and the leakage and short circuit of the electrical appliance or line. The mismatch between the leakage switch and the load generally occurs after the newly installed or newly added high-power household appliances such as air conditioners and electric water heaters. The matching air switch must be replaced.

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. After the low-voltage circuit breaker jumps open, first disconnect all the branches, and then close the power transmission one by one.

1.Clamp table hanging.

Come to the main switch, the source to see the current change, especially when tripping, the current is too large, change the switch to a larger one.

2.Each household has installed a leakage protector to prevent failures caused by leakage3The opening gate of each household is closed, the main gate is also closed, all electrical appliances are plugged, and then use the multimeter x10k gear to measure whether there is a resistance value between the live wire and the ground out of the main gate, and the resistance value or the resistance value is small is leakage, and the normal should be no resistance value or the resistance value is greater than 100m
