What s going on with the old jump of the electric switch? What s the matter with the electric switch

Due to the poor installation of the electric switch, in the case of poor installation of the electric switch, the lead of each pile head will be loose, with the passage of time, the fuse will soon be oxidized and burned off, resulting in undervoltage of the line, which will lead to the electric switch tripping, the actual power consumption of household appliances is too large, it will also lead to the electric switch tripping, the rated current of the line is fixed, more than it, it will automatically lose power if the load is not loaded. In this case, it is necessary to install a switch with the right amount of electricity used by the household so that there will be no tripping.

1.The air switch is broken.

2.A short circuit occurs in the line.

3.See if the leakage protector is installed, if it is installed, then see if the leakage protection button of the leakage protector jumps, and if it jumps up and presses it again.

4.The above are the reasons why it can't be pushed, and there is a possibility that the switch is small, the air conditioner is large, and the two do not match the inspection method: 1

First, check whether the leakage protection button of the leakage protector jumps. The current residential air conditioning circuit is generally equipped with a leakage protection module, which is the big one on the left of the line switch. There is also a total leakage switch.

Two reasons:1If there is a local short circuit fault of household appliances in a certain circuit, it is recommended that you find an electrician to help you repair it and find out the problem;

2.If it is confirmed that there is no short-circuit fault in the load, it is likely that there is a problem with the empty opening, and it is recommended to replace it with a new one.

This situation is mainly caused by the following reasons:

First, there is leakage in the power supply line;

Second, there is leakage of electricity in an electrical appliance;

The third is that the poor performance of the air switch itself leads to accidental tripping, or the power cord connector is not firmly connected, and there is a phenomenon of loose and poor contact resulting in heating tripping.

What's the matter with the electric switch that keeps tripping

First of all, it may be that the connection of the leads of each pile head in the electric gate is not firm, resulting in a short circuit of the line and causing tripping;

Secondly, it may be that the household electrical load is greater than the rated current of the circuit breaker; Finally, it may be that the electrical switch trips due to leakage or short circuit of electrical appliances or lines.

What's going on with the old jump of the electric switch? The old jump of the electric switch is because the contact in some places is not tight, and the phenomenon of sparks often occurs, resulting in a large current, through which the electric switch is easy to trip, and the line needs to be checked.

The old jump of the electric switch indicates that there is a short circuit in the circuit, you should find a person who understands the problem of the circuit, the circuit problem is solved, and the electric switch will not trip if it is closed again

This means that in the process of use, there is a phenomenon of circuit overload, or a part of the circuit has a leakage. Timely investigation should be carried out to avoid circuit hazards.

The electric switch is always jumping, indicating that there is a leakage or short circuit, and forcibly transmitting power can cause a fire.

Maybe the air switch is broken.

It is the phenomenon of leakage in the circuit, and I am really helping you look forward to it

What will be the reason for the total tripping of the socket at home? How to repair? : The control switch at home trips, which can be caused by any reason.

I specially asked the decoration master about this, and the master told me some inspection methods and reasons, which I will share with you below. Before talking about the specific workaround.

Here's why:1. It may be that the connection of the leads of each pile head in the electric brake is not firm, resulting in a short circuit of the line and causing tripping;

2. It may be that the household electrical load is greater than the rated current of the circuit breaker;

3. It may be that the electrical switch trips due to leakage or short circuit of electrical appliances or lines.

The principle of electric switch trippingThe reason why the electric switch trips is to play a protective role, because the line with excessive voltage is very dangerous, if people touch the leakage place, an electric shock accident may occur, so the electric switch will trip itself to cut off the power supply. Then its principle is that when the voltage is too large, the output current is greater than the input current, there will be an induced voltage formed, once the induced voltage is formed, the force that pushes the electric switch will appear in the fine structure of the electric switch, so that the switch trips.

The electric switch is always the reason for tripping:1. Short circuit of the load lineIf there is a short circuit in the circuit in the user's home, the circuit in the home will trip immediately within a short time after the electrical appliance is turned on, and it will not be able to send power to the electrical appliance at all.

2. Load leakage.

If there is a leakage phenomenon in the electrical appliances in the user's home, and there is a distribution box installed with PZ30 at home, then when the electrical appliances leak, the circuit at home will naturally trip, and the distribution box of the PZ30 distribution box will generally be equipped with a leakage switch, and when the electrical appliances leak, the circuit at home will naturally trip. At this point, the appliance should be discontinued.

3. Poor installation.

If the connection between the various leads is not firmly installed when the circuit is installed at home, then the lead will oxidize and heat up after the circuit is used for a long time, resulting in the phenomenon of tripping the air switch. At this point, the connections between the individual leads should be reconnected and securely connected.

The reasons for the old tripping are as follows:1. The tripping caused by the short circuit of the electrical appliances can be checked one by one, and the damaged electrical appliances can be repaired to solve the problem;

2. The circuit load is too large, when multiple electrical appliances are used at the same time, it will cause overload, and the meter switch will automatically trip, and you can buy a higher power meter;

3. Voltage instability, voltage instability is very common, and only need to buy a voltage regulator to solve it.

A certain pile head lead is not firmly connected and is in a loose state, resulting in tripping, if it is loose for a long time, it will cause the pile to heat up.

Oxidation, burn out the outer insulation of the wire, and emit sparks and burnt smell, resulting in undervoltage of the line, and the line needs to be adjusted and fixed; Leakage switch.

Mismatch with load: The actual electrical load of the household is greater than the rated current of the low-voltage circuit breaker on the line.

Generally, 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.

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

When a certain circuit is closed, the low-voltage circuit breaker cannot be powered, that is, the shunt is faulty, and this road should be disconnected and other shunts should be closed for power transmission. After the problem of fault shunting is found, the power is sent after repair; The line trips due to leakage caused by moisture: check the junction box in the kitchen and bathroom lines.

If it is found that there is dampness, dripping and other phenomena, it is caused by water seeping into the electrical pipeline. At this time, all the junction boxes and switch boxes associated with them should be opened, natural drainage and natural drying should be done, and the insulation of all joints should be re-bandaged, and the line should be naturally dried for 1 2 days, which can solve the problem of leakage and restore normal power supply. For new buildings, the wiring is more susceptible to moisture as it is not completely dry, and all rooms should be inspected.

1. Poor installation: due to the poor installation of the electric switch, in the case of poor installation of the electric switch, the lead of each pile head will be loosened, and with the passage of time, the fuse will soon be oxidized and burned off, resulting in undervoltage of the line, which will lead to the tripped of the electric switch.

2. Excessive power consumption: If the actual power consumption of household appliances is too large, it will also cause the electric switch to trip, because the rated current of the line is fixed, and if it is exceeded, the load will be automatically cut off. In this case, we need to install a switch with the right amount of electricity used in the home so that it doesn't trip.

3. Leakage and short circuit: If the line in the home leaks, or the electrical appliances leak, it will also cause the line voltage to suddenly become larger, so that there will be tripping. However, this situation is not easy to detect, so it is best to ask a professional electrician to check the electrical and electrical conditions of the home.

The first reason.

Because the heavy load exceeds the rated load, it is an overload protection trip.

The second reason, because some electrical appliances have grounding phenomenon, due to leakage protection and tripping can gradually plug in or open the electrical appliances, when opening a certain electrical trip, it is necessary to first check whether this piece is suspected of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load.

The third reason, check whether there is leakage can turn off or unplug other electrical appliances, open this piece separately, if it is turned on normally, it means that it does not leak, if it will also trip, it means that the problem is on this equipment.

The fourth reason, if there is no leakage equipment, it is a load problem, you can first see how big your air opening is (also pay attention to the allowable load of the meter), and then convert the total power of the electrical appliances in use, (refrigerator and air conditioner to compressor start whether to calculate the power), if there is indeed an overload that can not be adjusted to avoid it, it is necessary to consider the problem of meter expansion and air replacement.

The first is to check the household appliances, if it has not been tripped, but now it is frequently tripped, it must be paid enough attention to it, at this time it should be a certain electrical appliance failure, that is, what we call a short circuit.

The reason why electrical appliances always trip is overload, short circuit, and leakage.

1. Overload

High-power electrical appliances generally need to be equipped with 4 square wires, if the configuration is a flat wire, then the power of the hail code electrical appliances will exceed the wire load, causing the safety protection device of the electric switch, resulting in the tripped phenomenon of the electric switch. In this case, it is necessary to replace the wires with thicker wires, or to reduce the load on the circuit, that is, to unplug the electrical appliances.

2. Short circuit

If the wire at the junction of the wire is not firmly connected, or if it is loose after being used for a long time, there will be a short circuit, which will cause the safety protection device of the electric switch, and cause the electric switch to trip. In this case, it is necessary to reconnect the terminal position, and the connection must be firmly and tightly.

3. Leakage

The home is generally equipped with a leakage protection device, when the wire sheath is damaged, the source is uproar, there will be leakage, and the current between the live wire and the neutral line will exceed 30 milliamperes, causing the safety protection function of the leakage protection device, and the phenomenon of tripping. In this case, it is necessary to find the leakage location and replace the wire with a new one.

Tips to prevent tripping at home:

1. When using electrical appliances at home, it is best not to turn on multiple electrical appliances with relatively large power at the same time, because the total load of electrical appliances can not exceed the rated current of the wire, if it is, it is easy to cause tripping, for this reason, we should try to avoid using high-power electrical appliances at the same time.

2. In order to effectively prevent the home from always tripping, when we arrange the wires, we must choose the appropriate number of wires for wiring, and the square number of wires should be selected according to the load it needs to bear. If the electricity consumption of electrical appliances is relatively large, you should choose to use a wire with a larger square number.
