The fuse has a resistance value. In fact, even the wire has resistance, but the resistance of the wire is very small (the nature of the conductor). In general circuit calculations, we usually don’t count it, but the resistance of the fuse is obviously larger than the resistance of the equal-length ... Read More

The fuse is made of a lead-antimony alloy wire with a relatively low melting point and a resistivity, which is called a fuse. The comparison of voltage and constant resistance is more able to detect micro-current beyond the working range. Resistors need a higher current to fuse and burn electrical ... Read More

The rated current indicates the current value that does not cause fusing when applied stably. If the rated current is exceeded during use, fusing may occur when fusing is not expected. Considering that oxidation, expansion and contraction caused by long-term use will increase the resistance value, ... Read More

The function of the fuse is to protect the electrical appliance. When the current exceeds the maximum load that the electrical appliance can withstand, the fuse will automatically blow to protect the electrical appliance from damage. If the fuse is too thick, some people even use copper wire instead ... Read More

Generally speaking, it is not possible, because the resistance of the copper wire is small, so the internal energy generated when the current passes is small, and the melting point of copper is relatively high. Without the function of the protection circuit, it is easy to cause the fuse to blow. ... Read More

1. If it is caused by excessive electrical load or a short circuit, you can first disconnect all the wiring related to the xenon lamp, and check whether there is a ground short circuit in all the lines connected to it, and then try to ride it. If the fuse is not burned, there is a problem with the ... Read More

Fuse refers to an electrical appliance that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds a specified value. A fuse is a fuse that melts the melt with the heat generated by itself after the current exceeds a specified value for a period of ... Read More

The selection of general-purpose fuses is mainly determined from the following three aspects: (1) Selection of fuse type. The type of fuse is mainly selected based on the load situation and the size of the circuit short circuit current. For example, for the protection of lighting circuits or motors ... Read More

A high breaking capacity fuse is a fuse that is fused in a ceramic tube (or glass fiber tube) filled with quartz sand and uses quartz sand as the arc extinguishing medium. The melt is installed in a porcelain tube (or glass fiber tube) filled with quartz sand, and the quartz sand is used as the arc ... Read More

The following is a brief analysis of common faults and troubleshooting methods for fuses: A、 Melt fusing 1. Normal fusing due to short circuit fault or overload operation. Troubleshooting: Before installing a new fuse, first find out the cause of the melt fusing. If the cause of fusing is not ... Read More
