中国矿业学院和沈阳市继电器厂联合研制的μp-XGL—1型微机选线高压漏电保护装置于1986年7月28日在煤炭工业部技术发展司和机械工业部电工局的联合主持下,通过了鉴定。该装置对6～10kV系统的漏电及接地故障能够准确地选出故障支路,具有足够高的灵敏度及良好的抗干扰性能。对闪络性漏电隐患能及时发现,便于预防性检修。具有完善的自检试验功能及计时功能,是国内首次将微处理器技术用于高压选择性漏电保护的新产品,该装置性能可靠,体积小,可减少占地面积,节约基建投资,安装接线简便。目
ΜP-XGL-1 microprocessor-based high-voltage line leakage protection device jointly developed by China Mining Institute and Shenyang Relay Factory was jointly sponsored by the Technology Development Division of the Ministry of Coal Industry and the Electrical Engineering Bureau of the Ministry of Machinery Industry on July 28, The identification. The device can accurately select the faulty branch for the leakage and ground fault of 6 ~ 10kV system, and has sufficiently high sensitivity and good anti-interference performance. Flashover leakage hazards can be found in time, easy to preventive maintenance. Has a perfect self-test function and timing functions, is the first time the microprocessor technology for high-voltage selective leakage protection of new products, the device performance and reliability, small size, can reduce the footprint, saving infrastructure investment, installation of wiring Easy.
