News on November 17, the key science and technology project of the State Grid Corporation led by the China Electric Power Research Institute "Key Technology Research of UHVDC Bushing" successfully passed the acceptance
.
The research results can comprehensively improve the design and manufacturing level of U/UHVDC bushing in China, which is of great significance
for realizing the localization of U/UHVDC bushing.
It is understood that DC bushing has always been a bottleneck
restricting China's DC engineering construction and equipment localization.
At present, the DC bushings used in China's ultra/UHVDC converter stations rely on foreign imports, and the development of ±1100 kV UHVDC bushings is a worldwide problem, and it is in the preliminary research stage
at home and abroad.
The project has established an optimization design platform for UHVDC bushings with independent intellectual property rights, solved the key technologies of optimization design, manufacturing process and test of internal and external insulation structures of UHVDC bushings, and fully mastered the core technology
of UHVDC bushing development and testing with independent intellectual property rights.
The technical indicators of the developed "U" structure ± 1100 kV UHVDC wall bushing have reached the international leading level, filling many gaps in this field at home and abroad; The technical indicators of the ±500 kV converter casing developed have reached the international advanced level and can be directly applied to engineering
