You can t use copper wire instead of a fuse, so you can use a thick fuse

The thickness of the fuse is placed according to the load of electricity and the wire diameter of the wire in the circuit, and can not be thickened casually, if it is thickened, once the load increases (if the wire diameter is small) or the circuit fault fuse can not be blown in time, which may cause electrical fire. It is necessary to replace the wire and meter before replacing the fuse (** switch is generally used now). Your analysis of fuse burning there makes sense, it's hard to say about stealing electricity, you have to have evidence.

In the future, every household in your building will definitely install a single meter, that is, the power supply bureau will install a separate meter for each household and cancel the general meter in the building. In this way, disputes over electricity are avoided.

No. The fuse is blown when the electrical appliance is under heavy load and high current, which can protect the electrical appliance from being burned. If the fuse is too thick, the fuse cannot be blown when the current is large, which can easily cause the line to catch fire or burn the electrical appliances.

Generally, it can't, this will be more dangerous, because the fuse is too thick and it is difficult to blow out, which will be very dangerous.

Of course not, why is it called a fuse, if it is thick, it is not a fuse.

No, copper has a much higher melting point than lead, and it will be dangerous!

It is that there are more electrical appliances and the load is large, and it is very dangerous not to increase the fuse yourself, and it is easy to cause fire, so you can propose to the supply bureau to increase the amount of electricity meter.

No, if the coarse burns constantly, your appliances will hang up.

If it's too coarse, it's not good, so use the method of zoning power outage to check it.

It depends on the load of the appliance you are using.

1. The fuse can not be replaced by iron wire or copper wire, because the fuse is resistive.

The large and low melting point of lead-antimony alloy is made and the hole is changed, the resistance of copper wire and iron wire is smaller, and the heat generated is relatively small, so it is not easy to fuse when the circuit is too current, so it cannot protect the circuit. The role of the fuse in the circuit is to play the role of overload protection.

2. The fuse is also called the current fuse.

It is a kind of fuse, the main function is in the case of unstable circuit, the insurance Nabi wire will be abnormally high or hot in the current to meet the current to cut off the current, so as to protect the safe operation of the circuit, it can not be replaced by iron wire or copper wire.

3. The fuse is generally made of lead-antimony alloy with high resistivity and low melting point, and under the same external conditions, the resistance of copper wire and iron wire is relatively small, and the heat generated is relatively small. At the same time, the melting point of iron and copper is higher than that of Huichen, and it is not easy to fuse when the circuit is too current, and the circuit cannot be protected.

No. If copper wire is used instead of fuse, it will cause the accident to not be able to blow in time, so that the accident will expand and the accident point will increase. In the case of a transformer, if there is a short circuit in the low-voltage part, the transformer will be burned.

If the equipment in the switchgear is faulty, it will cause a short circuit in the arc, the accident will expand, and it is easy to burn the switchgear.

In order to prevent the occurrence of such incidents, the power management department should be equipped with corresponding insurance and spare parts, strictly manage in accordance with the requirements in production, find out the cause of the failure and then deal with it, and not simply put in the faulty lines and equipment to prevent the expansion of the fault.

The resistivity of copper wire is small and it is not easy to fuse. The function of the fuse is to fuse itself to cut off the current when the current rises abnormally to a certain height and heat, so as to protect the safe operation of the circuit.

A fuse is a wire made of a lead-antimony alloy with a relatively high resistivity and a low melting point, which is called a fuse. A fuse is also known as a fuse, which is defined in the IEC127 standard"Fuse-link"。It is an electrical component that is installed in the circuit to ensure the safe operation of the circuit.

Invented by Edison more than 100 years ago, the fuse was used to protect the expensive incandescent lamps at that time, and with the development of the times, the fuse protected electronic power equipment from overcurrent and overheating, and avoided serious damage caused by internal failures of electronic equipment.

Reasons why copper and iron wires cannot be used instead of fuses:

Because the resistance of copper wire or iron wire is small and the melting point is high, when the current is too large, the heat generated is not easy to reach the melting point, so it will not be blown and cannot play the role of insurance.

Extension of knowledge points:

Lead-antimony alloy wire is usually used as the fuse material.

The resistance of lead-antimony alloy is relatively large, while the melting point is relatively low, which is the physical property of lead-antimony alloy.

According to the thermal effect of the current (Q=i 2RT), if the current is too large, the lead-antimony alloy will fuse due to the high resistance of the lead-antimony alloy, and the lead-antimony alloy with a low melting point will fuse, thereby protecting the circuit and the electrical appliance.

The fuse can not be replaced by iron wire or copper wire, because the fuse is made of lead-antimony alloy with high resistivity and low melting point, the resistance of copper wire and iron wire is small, and the heat generated is relatively small, and it is not easy to blow when the circuit has a fault of excessive current, so that the circuit cannot be protected. The role of the fuse in the circuit is to play the role of overload protection.

The fuse is also called the current fuse, it is a kind of fuse, the main function is that in the case of unstable circuit, the fuse will be suitable for its own fuse to cut off the basic current at a certain height or heat of the abnormal current rise, so as to protect the safe operation of the circuit, it can not be replaced by iron wire or copper wire.

The fuse is generally made of lead-antimony gold with high resistivity and low melting point, and under the same external conditions, the resistance of copper wire and iron wire is relatively small, and the heat generated is relatively small. At the same time, the melting point of iron and copper is relatively high, and it is not easy to fuse when the circuit has a fault of excessive current, and the circuit cannot be protected.

Classification of fuses

There are many types of fuses, which can be divided into overcurrent protection and overheat protection according to the form of protection; According to the scope of use, it can be divided into power fuse, machine tool fuse, electrical instrument fuse, etc.; According to the volume integral, it can be divided into large, medium, small and micro; According to the Li Tan breaking capacity, it can be divided into high and low breaking capacity fuses.
