补充资料：自动重合闸
| 自动重合闸 auto-reclosing 广泛应用于输电和供电线路上的有效反事故措施。即当线路出现故障，继电保护使断路器跳闸后，自动重合闸装置经短时间间隔后使断路器重新合上 。大多数情况下，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，再次重合能成功，这就提高了电力系统供电的可靠性。少数情况属永久性故障，自动重合闸装置不再动作，需查明原因，予以排除。一般情况下，线路故障跳闸后重合闸越快，效果越好。重合闸允许的最短间隔时间为0.15～0.5秒 。线路额定电压越高，绝缘去电离时间越长。自动重合闸的成功率依线路结构、电压等级、气象条件、主要故障类型等变化而定。据中国电力部门统计，一般可达60％～90％。用电部门的另一种广泛应用的反事故措施是备用电源自动投入，通常所需时间为0.2～0.5秒。它所需投资不多而维持正常供电带来的经济效益甚大。 |
