Abstract: With the development of high voltage direct current (HVDC) projects in China, transmission capacity keeps growing, which makes the heating problem of resin impregnated paper (RIP) bushing more and more serious. Facing the challenge of further increasing transmission capacity of ±800 kV UHVDC project, we proposed and verified a design scheme of RIP converter transformer valve-side bushing by simulation and temperature rise test in order to avoid safety problem caused by serious heating and excessive temperature of RIP bushing. First, the hot-spot temperature of bushing was reduced by introducing outer-winding tube structure and increasing conductor diameter in the design scheme. Then, an improved calculation method for temperature distribution of RIP bushing was proposed and used to verify the thermal design of bushing. Finally, the bushing manufactured on the basis of the design scheme was verified by temperature rise test. The simulation and temperature rise test results show that the design scheme of RIP converter transformer valve-side bushing can meet the engineering requirements, whose current-carrying capacity can reach 6736 A (equivalent industrial frequency current).
