深部铜矿35kV总降压变电站的重建

针对白银公司深部铜矿35kV总降压变电站原系统设备、设施老化严重,备品、备件无法采购,保护和监控系统安全运行难以保障等实际情况,深部铜矿总变站进行了易地重建。在重建新系统中采用了ISA-1H型变电站成套微机保护、JK-1000变电站微机监测及监控综合自动化装置和带4套防误装置的手车式真空高压开关柜等新技术、新设备。

RE-ESTABLISHING 35kV GENERAL STEP-DOWN SUBSTATION IN DEEP COPPER MINE

The 35kV general step-down substation at deep copper mine of Baiyin Non-ferrous Metals Corporation has been reestablished in another place due to serious outdating of the equipment and facilities of original system, no channel for purchasing the spare parts and incapability of ensuring safety operation of protection and monitoring the system. In the reestablished system, some new technology and equipment have been adopted, such as complete set of microcomputer protection in ISA-1H type substation, comprehensive automatic installation of microcomputer monitoring and supervisory control in JK-1000 substation, as well as truck-type vacuum high-voltage switchgear with 4 sets of malfunction prevention devices, etc.
