一、概述1.用途及测量原理MXG-1型输电线路故障探测器是测定高压输电线路故障点(短路、断路、接地等永久性故障点)距离的专用仪器,它的最大特点是配合一些电力设备后可以进行带电探测。本仪器的测试是依据脉冲测距原理。在被测线路上送入一脉冲电压,当发射脉冲在线路上遇到故障时便产生反射,通过仪器的显示系统(示波管)便能迅速而又准确的确定
First, an overview 1. Purpose and measurement principle MXG-1-type transmission line fault detector is to measure the high-voltage transmission line fault point (short circuit, open circuit, grounding and other permanent point of failure) special instrument, its most important feature is to cooperate with some electricity After the device can be charged detection. The instrument test is based on pulse ranging principle. A pulse voltage is applied to the line under test, which produces reflections as the transmitted pulse encounters a fault on the line, which can be quickly and accurately determined by the instrument's display system (oscilloscope)
