低压线路漏电故障定位仪的设计

Design of Leakage Fault Location Instrument for Low Voltage Line

针对低压配电网线路结构复杂、接地故障发生概率高、故障点定位困难的问题,设计一种低压线路漏电故障定位仪。该定位仪采用专用的信号发生器及其控制器和信号采集装置,通过对线路施加电流信号并通过采集装置巡线检测来判断故障点。现场验证结果表明,该漏电故障定位仪能够迅速、准确地将故障部分识别出来,消除故障点,很有推广价值。

In view of the complex structure of low-voltage distribution network,the high probability of ground fault and the difficulty of fault location.a leakage fault location instrument for low voltage line is designed.The special signal generator,controller and signal acquisition device are used in the location instrument.The fault point can be determined by applying current signal to the line and inspecting the line by the acquisition device.The field verification results show that the fault location instrument can identify the fault part quickly and accurately,and eliminate the fault point.It has great promotion value.
