摘要
隔离开关是输变电中的重要设备,在地震中的损坏较为严重,其主要表现是瓷瓶根部断裂。笔者以一种典型252 kV隔离开关为例,采用有限元法对适用于3 km海拔的隔离开关进行抗震分析,并与低海拔对应产品进行比较。两种海拔的隔离开关均不满足AG5的抗震要求。
As a key component of power transmission and distribution systems, disconnector have suffered serious damage in previous earthquakes. Generally, typical destruction feature of disconnector during earthquakes appears as the breaking at bottom of insulator porcelain posts. In this paper, taking a typical 252 kV disconnector as an example, study the seismic behavior of 3 km-altitude disconnector on finite element and compare with low-altitude disconnector. The two kind of disconnector can＇t be satisfy earthquake-resistent design of AG5.
