摘　　要：直流GIS是实现未来轻型化、紧凑化海上换流平台以及海上换流平台向深远海发展的关键设备,在投入运行前对直流GIS进行实际工况的长期带电模拟试验,可以充分预测直流GIS在全工况下长期运行的相关性能,进而提升直流GIS投入运行后直流电网的安全可靠性。文中以±550 kV直流GIS作为研究对象,对其进行了相关介绍,提出了±550 kV直流GIS的长期带电试验方案,设计了长期带电试验回路并分析了回路中设备的选取方法,最后对±550 kV直流GIS开展了实际试验,验证了所提±550 kV直流GIS长期带电试验回路的可行性,为后续进一步开展直流GIS在全工况下长期运行时的相关性能研究工作奠定了坚实的基础。DC GIS is the key equipment to realize the lightweight and compact offshore converter platform and the development of offshore converter platform to the deep sea in the future.The long term live test of DC GIS simulating the actual working conditions before its operation can fully predict the relevant performance of DC GIS in the long term operation under all working conditions and improve safety and reliability of DC power grid after operation of the DC GIS.In this paper,±550 kV DC GIS is taken as the research object,and its relevant introduction is carried out.The long term live test scheme of±550 kV DC GIS is proposed.The long term live test circuit is designed and the selection method of equipment in the circuit is analyzed.Finally,the actual test of±550 kV DC GIS is carried out to verify the feasibility of the proposed long term live test circuit of±550 kV DC GIS,which lays a solid foundation for further research on DC GIS long time performance under all working conditions.
