摘要

高速接地开关提供了一种接近断路器的电力系统保护手段，但比熔断器便宜。要获得这种保护，需要具有极高的可靠性和与断路器兼容的操作速度。这里描述的是一种新的接地开关，能够在230千伏时6.7周期合闸，在69千伏时2.4周期合闸。合闸时间从合闸信号发出到接地开关触点闭合。

Ultrahigh-Speed Ground Switch - Application and Development

High-speed ground switches offer a means of power system protection approching that of a circuit breaker, yet are less expensive than fuses. To obtain this protection requires an extremely high degree of reliability and speeds of operation compatible with circuit breakers. Described here is a new ground switch capable of 6.7-cycle closing time at 230 kv to 2.4 cycle closing time at 69 kv. Closing time is measured from initiation of closing signal to ground switch contact make.
