铠装电缆泄漏电场的分析研究

Analysis on Leakage Electric Field of Armoured Cable

在煤矿井下高压供电电网工况智能监测系统中，为实现电压信号的检测，对供电用铠装电缆采取人为电场泄漏的方法形成柱形电场，本文以电场理论为依据，分析了柱形场电位的分布规律，并给出了实际应用的检测电路框图．

In order to measure the voltage signal of operating type in an intelligent monitoring system of high voltage power system in underground coal pit,an artificial leakage electric field must be made on the surface of armoured cable.This paper,based on field theory,gives a method to calculate the distribution of leakage cylindrical field and the block diagram of a practically used monitoring circuit.
