永磁固封式真空断路器在煤矿领域的应用

Solid seal type permanent magnet vacuum circuit breaker application in the field of coal mine

煤矿隔爆真空断路器是矿下电力系统的主要设备,其性能好坏直接关系到电网能否安全运行。结合煤矿电力系统环境,针对永磁固封式真空断路器结构、特点和温升问题的解决办法进行了介绍,并对永磁固封式真空断路器在煤矿领域的应用前景进行展望。

At present our country coal mine safety production form better,but with increasing intensity of coal mining,depth,put forward higher requirements on coal mine safety production. Coal mining flame-proof vacuum circuit breaker as the main equipment of power system under mine,its performance is good or not can directly related to the power grid safe operation. Based on coal power system environment,in view of the permanent magnet temperature rise of the enclosed type vacuum circuit breaker structure,characteristics and problem solution are introduced,and the solid sealing type permanent magnet vacuum circuit breaker application prospect in the field of coal mine was discussed.
