Abstract: ABSTRACT: Hybrid high voltage DC (HVDC) circuit breaker is one of the core equipment of DC power grid. In order to test and verify the rationality and validity of DC circuit breaker design, and accurately reflect the electrical, thermal and mechanical performance of DC circuit breaker, it is needed to study the operation test of HVDC circuit breaker. Taking the test standards of AC circuit breaker, converter valve and other similar products as reference, this paper studies the operation test item of HVDC circuit breaker. Firstly, we introduce the working principle of the test circuit used in operation test, and analyze the working conditions of related equipment at various moments. Then, we successfully complete a 83 kV prototype sample operation test, which can provide reference for HVDC circuit breaker with higher voltage level in the future.

Key words:  hybrid HVDC circuit breaker, VSC-HVDC,  , operation test
