Anaiysis on Release Circuit for Receiving Part in Section Without Point in Rear of Home Signal

对进站内方设有无岔区段接车局部解锁电路的分析

The tripping device is basically divided into the instantaneous electromagnetic release and the time delay thermal release, which are used for protection of circuit from shortcircuit and overload respectively.

高压断路器弹簧操动机构分闸脱扣部分的改进断路器由瞬时动作的电磁脱扣器和延时动作的热脱扣器组成，分别用作线路的短路和过载保护。

A power management circuit is designed, which can collect energy in a long time and release the energy to drive load in a short time.

并设计了电源管理电路，实现长时间内对磁电换能器输出电能的收集，瞬间放电，驱动负载工作。

The improving method of CB release circuit

断路器脱扣回路的改进方法

Protection against motor over-load usually adopt thermal relay, but protection against line over-load usually adopt long delay over-current release of circuit-breaker.

电动机过载保护通常采用继电器，而配电线路过载保护多采用断路器的长延时过电流脱扣器来完成。
