Abstract

DC high speed switch (HSS) is a key component in multi-terminal DC transmission system and is required to withstand long-duration DC arc abalation. According to the operating conditions and product characteristics of HSS in ± 800 kV hybrid multi-terminal HVDC transmission project

in this paper a constant current method of switching power supply for HSS long-term DC arc ablation test is proposed

and a constant current DC high current test circuit of switching power supply is designed. The technical parameters and device selection of the main equipment of the test circuit are also introduced. Based on the high-power power electronic switching device IGBT

the test circuit is set up and the HSS long-term DC arc ablation test is performed. The ablation test results of the prototype show that the test method proposed in this paper is feasible. Based on the test results

the selection of material type of nozzle and arc contact for 800 kV HSS products is proposed.
