The fully insulated design of the drop-out fuse improves the insulation level of the distribution network

drop out fuse 33kv Fully insulated design improves the insulation degree of distribution network

drop out fuse cut out is to install the melt in an insulating tube made of solid gas-producing material. The solid gas-producing material can be made of electrical anti-white paperboard or organic glass materials. When the short-circuit current passes through the melt, the melt will melt and produce an arc. The high-temperature arc will rapidly decompose the solid gas-producing material to produce a large amount of high-pressure gas, thereby spraying the ionized gas with the arc at both ends of the tube, emitting a great sound and light, and extinguishing the arc when the AC current passes through zero to disconnect the current.

drop out fuse element Fully insulated design improves the insulation degree of the distribution network and reduces the accident rate. Especially for urban distribution networks, it completely solves the exposed points of traditional drop out fuse in transformer:
drop out fuse price is an electrical appliance that uses a metal conductor as a melt in series in the circuit. When an overload or short-circuit current passes through the melt, it will melt due to its own heat, thereby disconnecting the circuit. drop out fuse set has a simple structure and is easy to use. It is widely used as a protective device in power systems, various electrical equipment and household appliances.

The closed structure avoids the problem of increased contact resistance caused by internal contact contamination, ensures the effectiveness of the equipment's electrical performance, and avoids the problem of decreased insulation resistance caused by contamination of the drop out fuse unit.
