If the meter replaces the fuse, must the electrician of the power supply bureau handle it?

I haven't heard of fuses for electricity meters!

It depends on where the fuse is! There is no place to open the seal, and those who understand it can change it. But you're talking about changing the meter, which must be from the power supply bureau, and they will unseal it and install one for you, and you won't have it! It's anti-user modification!

If the fuse is broken, find one of the same thickness and replace it yourself. I pull the electric switch apart (power-off state), tighten the screw with a screwdriver, replace it, and tighten it. I really won't, find someone who understands electricity, teach once, and don't ask for help next time.

It's better to switch to an air switch, and after tripping, just pull it.

There is no fuse on the meter, only the fuse on the gate blade, which can be replaced by an electrician.

Is the meter broken, the meter or the previous circuit of the meter is broken, and the power supply bureau must repair it. Otherwise, the power supply bureau will be fined.

It mainly depends on where your fuse is, whether it is sealed by the lead, as long as it is outside the seal, you can change it, do you wait for the electrician of the power supply bureau to deal with it the next day or deal with it yourself immediately?

It depends on what kind of fuse you are, if the air switch is broken, let the electrician replace it, but the general fuse, you can still replace it, as long as you choose the right fuse.

Change the fuse and find an electrician, let's make a big fuss.

It is best to call the electrician insurance point, and call the repair of household appliances in case of accidents, you are still responsible.

The question ... Generally, there is no electrician to repair it...

1. How to recover the tripping meter at home.

1. Open the box with the meter, find the blue button in the lower right corner of the internal meter, and press it back;

2. If the trip is caused by overload, the relevant electrical appliances will be powered off, and then the main switch will be pushed up;

3. If the main gate cannot be pushed up, reset the leakage protector button, and you can do it.

Second, how to maintain the meter box.

1. In daily life, it is necessary to regularly test the meter box to see if there is a problem, so as to repair it in time. The main thing is to see whether the meter box is damaged, whether there is a disorderly lap connection, and at the same time, when the electrical switch is opened, whether it will be flexible and easy, whether there will be noise, if this kind of situation occurs, it needs to be dealt with in time.

2. If you need a better fuse in the meter, then make sure that the fusing current can match the current in the circuit, otherwise there will be unnecessary trouble. Moreover, for the different voltages on the control box, it must be distinguished during the maintenance process to avoid short circuits, which will lead to serious problems.

3. When disconnecting the indoor power supply, it is necessary to detect whether the rack of the internal control cabinet is grounded, and measure the grounding resistance at the same time to keep it within 4. In addition, it is also necessary to clean the outside of the meter box on a regular basis to ensure cleanliness, and at the same time pay attention to electricity safety, so that the meter can be seen clearly to avoid accidents.

Summary. Hello, happy to answer your <>

The meter fuse burned 1 and opened the fuse. 2 Loosen the screws and remove the original broken fuse. 3 Straighten the fuse.

Curve clockwise. Press against the screw at the upper end of the fuse slot. Tighten.

If the fuse is loose, it is easy to blow. After that, unscrew the lower end. The steps are the same as above.

4 Finally, press the fuse into the fuse slot. Buckle the safety cover.

How to change the fuse of the meter when it burns out.

Hello, happy to answer your <>

The meter fuse burned 1 and opened the fuse. 2 Loosen the screws and remove the original broken fuse. 3 Straighten the fuse.

Curve the ants in a clockwise circle. Press against the screw at the upper end of the fuse slot. Tighten.

If the fuse is loose, it is easy to blow. After that, unscrew the lower end. The steps are the same as above.

4. Finally, the fuse is pressed into the fuse slot without a core. Buckle the safety cover.

Dear, the following is an extension <> for you to imitate the erection

A fuse is also known as a current fuse, and the IEC127 standard defines it as:"Fuses"。It mainly plays the role of overload protection. If the frontal fuse is correctly placed in the circuit, the fuse will fuse itself to cut off the backup base when the current rises abnormally to a certain height and heat, so as to protect the safe operation of the circuit.

When the circuit is faulty or abnormal, it is accompanied by a continuous increase in current, and the elevated current may damage some important components in the circuit, and may also burn the circuit or even cause a fire.

Will it touch the electricity.

Yes, pro. So what to do.

It is recommended that you go to a professional repair point for repairs.

I found another phenomenon just now, that is, the two fuses under the meter, should be an incoming line and an outgoing wire, right? Now one is hot, the other is cold. Is it possible to determine that it is a leakage? Or is there a problem with the fuse holder?

A: The current intensity of the incoming and outgoing lines is the same. A fuse is cold (liveline?)

It means that the current passing through is not large and will not be leakage. If one of them is heated, it is certain that there is a problem with the fuse holder, the screws and gaskets are rusted or overheated and sintered, or the screws are not tightened, resulting in poor contact and heating, causing the fuse to burn out frequently. You can try tightening the screws, but if you can't, you have to replace the hot fuse holder.

And that's why you change the fuse once a week. If there is no poor contact, the fuse that heats up is a live wire, and leakage is considered.

Q: What is the manufacturer of the leakage protector, how much ampere is the current, how big is the fuse, has the decoration circuit been inspected, and whether the lamp and socket wiring are separated.

Reasons: 1. There is a switchable socket wire, which is not tightly connected and loose, and it is easy to appear when the inner wire is damaged in humid weather, or the terminal head is not tight when the refrigerator starts the motor, causing the leakage switch to jump or the fuse to break;

2. It is also possible that the internal wiring of the refrigerator is caused by moisture (which often occurs in water heaters).

Suggestion: It is best to replace the fuse with a miniature circuit breaker (switch without leakage protection), at present, the standard Huai home decoration socket circuit is all protected by leakage switch, and it will not always jump to the total open, so as to distinguish which circuit switch jumps first, and you can immediately judge what the problem is.

The leakage switch trips from time to time, is it that the wiring of your strong current box is not connected well? You carefully pull the four wires that leak in and out to see if they are loose. How many A fuses are you using?

Or what is the maximum current of your meter, you can buy it back and install it according to its maximum current. A 300-block strong current box? Isn't it all-inclusive?

How many power boxes do you have? Generally, it can be installed with 18-bit 1p is 80, a bipolar leak warranty costs 30, and a 1p empty opening costs 8 yuan. The labor cost is 5 yuan per 1p empty opening, and 20 yuan for bipolar leakage insurance.

Do the math yourself.

To see if it is a dark wire or an open wire, it should be caused by the leakage of electrical appliances, you try to disconnect all the plugs of electrical appliances, and then try each electrical appliance separately to see if the fuse will break. If it is broken, it is a problem with the wire, and if it is continuous, it is a leakage of electrical appliances.

When the house was built, the wiring in the wall was not right, and it seemed to be copper wire. It is easy to trip and will not be safe.

The fuses are all broken, then it must be overcurrent, how much is your total opening?
