Abstract

The invention discloses an intelligent vacuum circuit breaker with self-diagnosis and self-protection functions, and particularly relates to the technical field of vacuum circuit breakers, the intelligent vacuum circuit breaker comprises a bottom plate and a vacuum circuit breaker body, the vacuum circuit breaker body is arranged at the top of the bottom plate, and the outer side of the vacuum circuit breaker body is sleeved with a protection cover; a temperature sensor and a humidity sensor are fixedly arranged on the surface of the inner wall of the top of the protection cover. The temperature and humidity in the cover are monitored in real time through the temperature sensor and the humidity sensor, when the temperature is too high, the power of the miniature fan is increased, the temperature becomes low, and the humidity is large, the miniature fan is adjusted to reduce the rotating speed, moisture is dried through heat of the vacuum circuit breaker body, normal operation of the vacuum circuit breaker body is ensured, and the service life of the vacuum circuit breaker is prolonged. When the smoke alarm detects smoke, the single-chip microcomputer is used for controlling the electromagnetic valve to be opened, dry powder rapidly flows out of the round pipe to extinguish fire, manual operation is not needed, the self-diagnosis and self-protection effects of the device are achieved, and the device is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to an intelligent vacuum circuit breaker with self-diagnosis and self-protection functions. Background technique [0002] With the rapid development of electrified railways in my country, the quality of railway power supply systems has also improved. In the process of high-voltage power transmission in railways, vacuum circuit breakers are usually used to control and protect circuits. Vacuum circuit breakers have high reliability and volume Small size, light weight, low noise and other advantages, so it is widely used in power distribution systems in various fields such as power industry, industrial and mining enterprises, railway transportation, etc. It is one of the indispensable main equipment for the production and operation of the power industry. It is mainly used as the core actuator of a complete set of switchgear. During daily use, it is necessary to operate, o...
