In today’s electrified and intelligent life, security is the most important problem we should pay attention to. The security problem can be said to be involved in every person and in every field. Therefore, how to use our scientific and technological equipment safely is one of the inescapable topics in our scientific research. The fuse box is one of the safety devices we designed to protect our safety in using all kinds of equipment.

Fuse box
The so-called fuse box, in fact, the actual working principle is very similar to the fuse we use in the circuit. Because it has a box and is also called a fuse box, we first understand the principles and uses of the box before we fully understand the principle of the fuse box. In order to ensure the safety and normal work of the fuse, the function of the fuse box is usually waterproof, sunscreen, and avoid high temperature. The current fuse box is mainly a fuse box and a car fuse box. As we all know, if the fuse is used, it will change its electrical conductivity if it is affected by high temperature or water, which will cause the work to be abnormal and dangerous. Therefore, fuse boxes are usually made of materials that are not transparent or completely sealed.
Fuse principle
I think everyone should be familiar with the fuse. In fact, the fuse is a section with a resistance related conductor. Its function is to ensure that the circuit breaks off when the current is too large in the circuit and makes the whole circuit break, so that the circuit can be protected well when the current is too large, so as to avoid the danger of the whole circuit fire. Therefore, the fuse must be a conductor, and it is necessary to specify that the resistance of the fuse is large enough, because we know that the fuse has to produce a certain temperature. The greater the resistance is, the greater the temperature and the heat of the conductor. In addition, the fuse’s melting point can not be too high, or it will be difficult to fuse to the protection circuit. The role.

classification
The type of fuse box is very many. If it is classified according to the fuse wire, it can be divided into insurance box and insurance box. If the fuse is classified according to the size of the fuse, it can be divided into middle, large and small types of fuse boxes. If the material is divided according to the material, it can be divided into plastic fuse box and the electric wood fuse box. In addition, we can also divide the content according to the environmental protection content. If we divide the environment according to the environmental protection, we can divide the fuse boxes into the environmental protection fuses box and the non – Environmental fuse box. There are also car fuse boxes and lead fuse boxes.
The function and type of the fuse box is so much, we can see from here that the function of the fuse box is to protect the safety of the whole circuit, eliminate the hidden fire caused by the excessive use of electricity, and ensure the normal operation of the circuit.
