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。 |
