由中国矿业学院与沈阳继电器厂联合研制的μρ-XGL-Ⅰ型微机选线式高压漏电保护装置(简称保护装置),于1985年10月在我局庞庄矿变电所进行了工业试验及工业运行(现仍在运行)。该装置具有选线正确、抗干扰能力强、体积小、投资少等优点。我局1987年2月购买13台,分别安装在各矿高压变电所。现将安装运行情况作一介绍。一、保护装置的工作原理及安装μρ-XGL-Ⅰ型微机选线式高漏保护装
Μρ-XGL-Ⅰ microprocessor-based high-voltage line leakage protection device (hereinafter referred to as protection device) jointly developed by China University of Mining and Shenyang Relay Plant, carried out industrial test in Pangzhuang Mine substation of our bureau in October 1985 and Industrial operation (currently in operation). The device has the right line selection, anti-interference ability, small size, less investment and so on. I Bureau in February 1987 to buy 13 units, were installed in the mine high voltage substation. Now the installation of operating conditions for an introduction. First, the protection of the working principle and installation μρ-XGL-Ⅰ-type microcomputer high-line leakage protection line
