摘要
目前,市面上最新的直流系统绝缘监测装置已经能够查找毫秒级的直流系统瞬时接地故障,能够选出瞬时接地时的馈线支路.但直流系统瞬时接地故障存在偶发性与非持续性,无法使用便携式接地查找仪定位故障点.文章基于无线通信设计一款定位瞬时接地故障点的直流系统瞬时接地定位系统.
Abstract
The latest insulation monitoring devices for DC systems on the market are capable of detecting millisecond level instantaneous grounding faults in DC systems and selecting feeder branches during instantaneous grounding.However,due to the sporadic and non persistent nature of transient grounding faults in DC systems,portable grounding locators cannot be used to locate the fault point.This article designs a DC system instantaneous grounding positioning system based on wireless communication to locate instantaneous grounding fault points.
