一种±500 kV换流站现场直流耐压试验装置集成化改造的研究及应用

Research and application of One method of DC voltage test Equipment's integrated transformation in ±500 kV converter Station

直流耐压试验设备现场需进行多次重复拆卸、移动、组装、试验及装箱运输。为了保证试验设备的可靠性及长途运输的安全性,降低现场组装和拆卸的风险,提升现场试验的效率,以云南电网±500 kV直流输变电工程的现场直流耐压试验为例,提出了一种±500 kV换流站现场直流耐压试验装置集成化改造的方法。

Repeated demolition, movement, assembly, testing and packing are required in DC withstand test. In order to ensure the reliability and long-distance transport of security,reduce the risk of on-site assembly and disassembly, improve the effi ciency of fi eld testing, take DC withstand test of ±500 kV Yong-Fu DC Power transmission project as an example in this paper, a method of integrated retrofi t of DC voltage withstand test device in ± 500 kV converter station is successfully completed.
