屯兰工广变电站6 kV开关柜改造工程研究

Research on Reconstruction Project of 6 kV Switchgear in Tunlan Gongguang Substation

针对矿井变电站开关柜改造,提出了不影响矿井双回路正常供电的运行方式,通过使用临时闲置开关柜、敷设临时沟通电缆等措施,调整运行方式,在有限的时间内完成站内6 kV开关柜改造,在西山煤电屯兰工广35 kV变电站供电设备改造工程中得以应用。

In view of the reconstruction of switch cabinet in mine substation,this paper puts forward the double circuit operation mode that does not affect the normal power supply of mine.By using idle temporary switch cabine,laying temporary communication cable and other measures,the operation mode is adjusted,and the reconstruction of 6kV switch cabinet in the station is completed in a limited time,which can be applied in the reconstruction project of 35kV substation power supply equipment in Tunlan Gongguang of Xishan Coal and Electricity.
