How to eliminate the arc generated in the fuse?
Latest company news about How to eliminate the arc generated in the fuse?

        The arc is maintained by thermal dissociation. Reducing the temperature of the arc can weaken the thermal dissociation and reduce the generation of new charged ions. At the same time, it also reduces the motion speed of charged particles and strengthens the composite effect. The arc temperature can be reduced by rapidly lengthening the arc, blowing the arc with gas or oil, or making the arc contact with the surface of solid medium.

        The characteristics of the medium in which the arc burns largely determine the intensity of deionization in the arc. Including thermal conductivity, thermal capacity, thermal dissociation temperature, dielectric strength, etc.

        The pressure of the gas medium has a great influence on the arc deionization. Because the greater the pressure of the gas, the greater the concentration of particles in the arc, the smaller the distance between particles, the stronger the composite effect, and the easier the arc is to extinguish. In the high vacuum environment, because the probability of collision is reduced, the collision dissociation is restrained, but the diffusion effect is very strong.

        The contact material also affects the deionization process. When the contact is made of high-temperature resistant metal with high melting point, good heat conduction and large heat capacity, the hot electron emission and metal vapor in the arc are reduced, which is conducive to the extinction of the arc.
