自动重合闸广泛应用于架空输配电线路上,因为在大多数情况下,架空线路故障(如雷击、风害等)是暂时性的,断路器跳闸后线路的绝缘性能(绝缘子和空气间隙)能得到恢复。当线路出现瞬时故障,继电保护使断路器跳闸后,自动重合闸装置经过短时间间隔后使断路器重新 Automatic reclosing is widely used on overhead power transmission and distribution lines because overhead line faults (such as lightning strikes, wind damage, etc.) are temporary in most cases. The circuit insulation (insulators and air gaps) Be restored. When the line appears instantaneous failure, the relay protects the circuit breaker to trip, the automatic reclosing device makes the circuit breaker restart after a short time interval
