Fireproof fuse capable of fusing and automatically replacing wires

Abstract

The fireproof fuse comprises a shell fixedly installed in power distribution equipment, a sealing plate is hinged to an opening in the lower end of the shell, two connecting sleeves are integrally and symmetrically arranged on the two sides of the upper end of the shell, wiring pipes are fixedly arranged on the inner sides of the sleeves, and the wiring pipes are connected with the sealing plate in an integrated mode. The inner side of the wiring pipe is provided with a connecting cable, and the inner side of the connecting sleeve and the inner side of the wiring pipe are in threaded connection with wiring bolts. The fire extinguishing box is fixedly connected to the upper surface of the shell, an agent cavity is formed in the inner side of the fire extinguishing box, a condensation cavity is formed in the outer side of the agent cavity, the agent cavity and the condensation cavity communicate with each other, and meanwhile an air injection hole is formed between the condensation cavity and the shell. The fusible fireproof fuse capable of automatically replacing the wires can automatically replace the wires according to heat generated when the wires are broken, on-site operation of workers is not needed, meanwhile, automatic fire extinguishing and fire prevention can be achieved, and use safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a fireproof fuse that can be blown and self-replaceable. Background technique [0002] A fuse refers to an electrical appliance that fuses the melt with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. It is an indispensable protection device in the power system, but there are still some existing fuses. insufficient. [0003] For example, an automatic replacement device for fuses for power distribution cabinets with publication number CN110429014B, when working, rotate the storage box, drive the storage box to rotate through the rotating shaft, rotate to the position of the feed slot, and squeeze through the frame of the feed slot. Press the telescopic block to compress the telescopic block to the side of the top extension spring, and then drive the sliding rod to move... The pressure spring pushes the fuse block into the body ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fire-proof fuse that can be blown and self-replaced to solve the problem that the current fuses on the market cannot automatically replace the melt, which increases the risk of operation and does not slow down the power consumption. The recovery speed of the system, and at the same time, it cannot play a good fireproof performance during the fusing process, so that the high temperature generated during the fusing process can damage the overall problem of the equipment
