摘　　要：针对煤矿井下高压配电装置隔离触头常因接触不良引发温度过高,继而导致故障且不易检测的问题,提出了一种矿用高压配电装置隔离触头温度在线监测系统的设计方案,重点阐述了该系统下位机软件程序和基于LabVIEW虚拟仪器开发平台的上位机在线监测程序的设计。试验结果表明,该系统能够实时远程监测矿用高压配电装置隔离触头的温度信息,误差小于1℃,符合工程实际要求,且能够根据监测的温度信号进行故障诊断和预警。For problems that high temperature caused by bad contact of isolator of mine-used high- voltage distribution equipment usually leads to faults and the faults are hardly detected, a design scheme of on-line monitoring system for temperature of isolator contact of mine-used high-voltage distribution equipment was put forward and software designs of lower computer program and on-line monitoring program based on LabVIEW of the system were introduced emphatically. The test result showed that the system can monitor temperature of isolator contact of mine-used high-voltage distribution equipment real- timely and remotely with error less than 1 ℃, which can meet requirement of actual project. Besides, the system has functions of fault diagnosis and early warning according to monitored temperature signal.
