引言自动分段器是配电网中用来隔离故障线路区段的自动开关设备,在无电压或无电流情况下自动分闸。分段器按识别故障的原理不同,可分为“电流-时间”型和“电压-时间”型两大类。“电流-时间”型分段器通常与前级开关设备(重合器或断路器)配合使用,它不能开断短路电流,但具有“
INTRODUCTION Automatic segmenters are automatic switching devices in the distribution network that are used to isolate faulty line sections and automatically open without voltage or with no current. Segmentation devices according to identify the different principles of failure can be divided into “current - time” type and “voltage - time” type two categories. The “current-time” type of sectionalizer is usually used in conjunction with a front-stage switching device (recloser or circuit breaker) which does not interrupt the short-circuit current but has the "
