Quick cooling protection mechanism used after short circuit of circuit breaker in intelligent manufacturing

Abstract

The invention discloses a quick cooling protection mechanism used after short circuit of a circuit breaker in intelligent manufacturing. The quick cooling protection mechanism used after short circuitof the circuit breaker in intelligent manufacturing comprises a shell, wherein an inner cavity is arranged in the shell, the top of the shell is fixedly connected with an inflatable airbag, a springpipe extending into the inner cavity is fixedly connected to the bottom of the inflatable air bag, a piston plate is fixedly connected to the bottom of the spring pipe, a connecting hole is formed inthe right wall of the shell, a storage cavity is formed in the left wall of the shell, and a movable groove is formed in the bottom of the storage cavity. According to the quick cooling protection mechanism used after short circuit of the circuit breaker in intelligent manufacturing, the circuit breaker is filled with the transformer oil, so that dissipation of heat in the circuit breaker is accelerated, internal components are protected, and meanwhile, the effect of isolating dust to lubricate mechanical parts is achieved. In this way, the situation that a circuit cannot be cut off in time and losses are caused due to transmission jamming caused by dust or abrasion of internal mechanical parts can be prevented.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to a rapid cooling protection mechanism used in intelligent manufacturing after a circuit breaker is short-circuited. Background technique [0002] The circuit breaker is a basic protection device in the power system. When the circuit is short-circuited, it can cut off the circuit in time to prevent the strong current generated after the short-circuit from burning the short-circuit or electrical appliances and reduce losses. It is widely used in intelligent manufacturing, sewage treatment, and household circuits. use. [0003] While the circuit breaker cuts off the circuit through the magnetism generated by strong current, these magnetic coils will also generate a lot of heat. If the heat is not dissipated in time, it will cause damage and aging of its internal components, especially the surface of the magnetic coil may be damaged. The varnish falls off, which makes t...

[0003] While the circuit breaker cuts off the circuit through the magnetism generated by strong current, these magnetic coils will also generate a lot of heat. If the heat is not dissipated in time, it will cause damage and aging of its internal components, especially the surface of the magnetic coil may be damaged. The varnish falls off, which makes the magnetic coil short-circuit itself and cannot be used normally. Therefore, we propose a rapid cooling protection mechanism for the short-circuit of the circuit in intelligent manufacturing.
