What is the reason for the constant tripping and power outage at home?

First, the line is overloaded, and large household appliances are not wired separately.

When decorating, many families will put high-power sockets such as air conditioners and water heaters together with ordinary sockets because they want to save lines and money.

This is a very serious problem, on the one hand, it will make the air open trip frequently.

On the one hand, it will heat up the wires.

Therefore, high-power household appliances must be routed separately and controlled by separate air opening;

The home circuit always trips, don't panic, the old electrician will help you analyze the cause of the trip.

If the number of wires is reserved.

If it is enough, then there is no need to replace the wires, and directly replace the larger air switch.

can solve this problem.

Second, there is a short circuit at the load end, which will jump as soon as it is sent or jump after a while.

That is to say, there is a short circuit on the electrical end, such as water heaters, kettles, refrigerators, air conditioners, these household appliances will have a short circuit.

The home circuit always trips, don't panic, the old electrician will help you analyze the cause of the trip.

For example, the working mechanism of the refrigerator is to power on for self-check, after the self-test is completed, it can be preheated, and then the compressor starts to work, if the compressor is short-circuited, it will trip only when the compressor is working, which is why it will trip after a while, and the same is true for air conditioners.

3. The load end is grounded, and there is leakage.

There is also a situation of leakage of household appliances, which is also more common in the family, because of the high humidity in summer, the switch box of many families has not been sealed, and the water flow and water vapor are easy to flow into the switch box through the wall, and then there is a leakage short circuit to the ground.

The home circuit always trips, don't panic, the old electrician will help you analyze the cause of the trip.

Don't worry about this situation, first disconnect all the air opening, and then send power all the way to the experiment, that all the way to jump away is which way there is a problem, disassemble the switch box in a power failure, use a hair dryer to dry, cover the switch box, and then glue and seal it to continue to use.

Fourth, the air switch itself is a problem, and the contact is poor.

There is also the quality problem of the air switch itself, so it is recommended to try to use the best and big brand household appliances when selecting materials for decoration to avoid problems and need to be replaced.

The home circuit always trips, don't panic, the old electrician will help you analyze the cause of the trip.

If you feel the air switch and get hot, and occasionally you can hear a sizzling sound, then it is possible that the contact is not good and the trip is caused by it, and you only need to use a screwdriver.

Just retighten the terminals.

1. Because the heavy load exceeds the rated load, it belongs to the overload protection tripping.

Solution: Control the power consumption and do not overload.

2. Because some electrical appliances have grounding phenomenon, they trip due to leakage protection. You can gradually plug in or open the electrical appliances, when opening a certain electrical appliance tripping, you must first check whether there is a suspicion of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load.

Solution: Check and repair electrical appliances to solve the grounding phenomenon.

1. The circuit has poor contact or slight leakage (this is more troublesome);

Second, the leakage switch itself is faulty, and it is faster to replace this switch.

Be sure to pay attention to the safety of electricity, and it is recommended to find an electrician or a professional who understands electricity to deal with it.

It's probably because of aging circuits, or it's because the voltage in your home is too high.

Check if there is a short circuit somewhere, the wire will age after a long time, if there is no short circuit, it is too many electrical appliances in your home, the power consumption is large, and the wire overload will also trip, you have to replace the wire with a thicker copper wire to solve the problem.

Then check whether any of the appliances in your home have been short-circuited, or the total power exceeds the power of the switch.

There are three reasons for the old tripping of the electric switch: 1. Caused by overload; 2. Caused by short circuit; 3. Caused by leakage.

caused by overload. In the use of some electrical appliances, for example, the wire is a square lighting wire, but it is used in high-power appliances. The power of the appliance greatly exceeds the load on the wires. At this point, the safety device of the switch is activated, causing a trip.

Caused by short circuits. At the interface where the wires are connected, sometimes they are not connected firmly, or if they become loose after a period of use, which can cause a short circuit. At this time, the safety protection device is opened, and the power is tripped and the power is cut off to prevent fire.

3. Caused by leakage. There will be a leakage protection device for household electricity, and as long as the current difference of the fire zero line exceeds 30 milliamperes, it will touch the safety protection and cause tripping.

The old trip must be a fault in the outgoing circuit of the home, which touches the protection device. Therefore, it is important to find a professional to find out the cause and solve it in time to ensure safety.

The causes and solutions are as follows:

1. Check whether there are high-power electrical appliances at home, as power outages are caused by long-term use or aging lines.

2. Check the switch at home, the best way to check is to take a small bulb and connect it to the terminal post of the switch, if the bulb is on, it means that the switch is broken, and you can find the electrician to change the switch.

3. Check whether there are wires broken at home, especially where the switches are switched.

4. Look at the total meter at home, there is a gate in the meter, if the gate in the meter jumps, it will also cause no electricity at home.

5. It may also be because the meter is broken. If you have a universal meter at home, you can test it yourself, and the voltage at the inlet of the universal meter reaches 220V, which means that the power outage caused by the broken meter. If you have a problem with the meter, you need to find a professional electrician.

Precautions

1) The common notification method of power supply enterprises is to announce and notify users. When issuing a notice of planned maintenance and power outage, the lead time limit of the power outage announcement shall comply with the provisions of laws and regulations. Some power supply units do not follow the time of prior notice or announcement as prescribed by law 7 days in advance.

Some planned maintenance and power outages were only announced three days in advance. The relevant handling units shall strictly abide by the advance time limit for issuing power outage notices, supply power in accordance with the law, and avoid mistakes.

2) The number of power outages.

The number of planned maintenance outages directly affects the economic interests of both the supply and consumption parties. The number of blackouts is arbitrary, but statutory. Article 57 of the "Power Supply Business Rules" stipulates:

Power supply enterprises should continuously improve the reliability of power supply, and reduce the number and duration of power outages for users caused by equipment maintenance and power system accidents. The planned maintenance of power supply equipment should be arranged in a unified manner.

When the power supply equipment is planned to be overhauled, the number of power outages for users with a voltage of 35 thousand volts and above should not exceed one per year; of users of 10 kV and above, it should not be more than three times a year. "

3) The time to restore the power supply.

Article 69 of the Business Rules for Electricity Supply and Consumption stipulates that "after the cause of power outage or power rationing is eliminated, the power supply enterprise shall restore power supply within three days." If the power supply cannot be restored within three days, the power supply enterprise shall explain the reasons to the user. ”

4) Pay attention to the relevant issues when signing the power supply contract.

The Regulations on the Use of Electricity** stipulate that when power is cut off due to planned maintenance of power supply facilities, users shall be notified or announced in advance. When signing a contract, the specific method of public notice or special notice shall be clearly stated in the contract. For example, the contract stipulates the use of **notice, written notice or press announcement**.

There are generally four reasons why an air switch trips:Overload protection, circuit short-circuit protection, leakage protection, undervoltage protection,All four of these causes can cause the air switch to trip.

After the power grid went out, the appliances in your home were not turned off. Your home may have a high-power electrical appliance started when the power was just delivered (for example, the refrigerator and air conditioner started at the same time when the electric water heater was turned on), and the starting current exceeded the rated current of the main switch, and it will trip.

Air tripping is a normal phenomenon, because of the power failure, resulting in an instantaneous increase in voltage after the call, and finally the empty trip, even if it does not trip, it should be turned on every month, and then turn on, in this way, the voltage will be cleared and counted again. Hope it helps.

A normal power outage will not cause the home to be tripped empty. You have to find someone who understands electricity to help you check and analyze the specific cause. Because when you ask a question online, you have to provide enough information to get an answer that can solve the problem, otherwise you can only fill in the details by constantly asking questions, and keep repeating the process, and it will take a long time to solve the problem.

The main reasons are: 1. There is a problem with the line at home, which may be a bad connection of a certain line, resulting in ignition and even short-term power outage. 2. Whether the zero line is broken. 3. Consider line breaking.

4. The electricity meter at home is broken. 5. Caused by loose clamping screws of lamp switches or main power switches. Suggested workaround:

1. If it is a problem with the line, it is recommended that you pay attention to the connection of each wire in the home, and feel whether there is a phenomenon of ignition, or overheating, and the line will be connected by chance once it is stable. 2. Test the two holes of the socket with a test pen, and the lights of the test pen are on, but the zero line is broken. Look at whether there is electricity in other people's homes, and look at the place where the zero line and the main zero line are connected, the probability of general problems appearing here is relatively high, especially when using high-power electrical appliances.

3. The treatment method of line disconnection is to add a resistive load, such as an incandescent lamp, and measure the resistance value of the switch (at this time, it must be powered off) after turning on the light control switch, so that the fault source can be judged. Then look for it in segments. 4. If you have a universal meter at home, you can test whether the meter is broken.

If the voltage at the incoming line of the universal meter reaches 220V, it indicates that the meter is broken and the power outage is caused. If you have a meter problem, you need to find a professional electrician. 5. If there is a power outage at home, it is not tripped, check whether the clamp screws of the lamp switch or the main power switch are loose.

Once the wire is loose, it is normal when not using electrical appliances or using low-power electrical appliances, but when you turn on the light, due to the increased load, the clamping screw will ignite and sizzle.

Summary. Dear, the solution to the tripping power outage at home: 1

First check the distribution box at home, whether the main gate and the leakage of the empty open have jumped, if they are all closed, it is not enough electricity 2If the main switch jumps, and the other empty openings do not jump, unplug the electrical equipment sockets on all the sockets at home, and come back to close the main gate to see if it still trips? If it does not jump, there are too many electrical equipment, resulting in excessive electrical load, and the main switch needs to be replaced.

Dear, the solution to the power outage at home tripped: 1First check the distribution box at home, the main gate and the leakage of the empty open has jumped down, if it is closed, it is enough to shoot the electricity bill 2

If the main switch jumps, and the other empty openings do not jump, unplug the electrical equipment sockets on all the sockets at home, and come back to close the main gate to see if it still trips? If you don't jump, there are too many electrical equipment, resulting in excessive electrical load, and you need to change the large limb main switch.

Can you tell us more about that?

3.The total gate tripped, and other air openings also have jumped brakes, disconnect all the electrical equipment below the trip, and then press the reset button of the empty open under the lack of a base, close the air open, if it is closed, it is a short circuit of the cracked Fengbi electrical equipment, and then check which equipment trips after the power is connected to contact the merchant after-sales treatment 4Close the main gate and open the sub-item, do not lift the gate at that time, and it will trip, it may be that the line is aging or the wire is damaged when the decoration is threaded, and it needs to be repaired and replaced by a professional electrician.

Summary. When the voltage in the circuit is too low during a power failure, the device will automatically trip the circuit breaker. Because there will be two changes in the undervoltage tripper when the undervoltage trips, one is that the reset button of the undervoltage tripper will protrude, which cannot be closed directly, and the button needs to be pressed to close normally.

The other is the position of the blue square reset button is a display screen, the screen is green during normal use, the screen turns red after tripping, it can be closed directly after tripping, and the screen returns to green after closing. Whether it is an undervoltage tripper or a leakage protector, the first thing to check after tripping should be the status of the accessory for circuit breakers with such accessories, so as to determine the cause of circuit failure.

Is it dangerous? There will be certain risks, it is recommended to find a professional to check it to ensure the normal operation of the switch.
