The invention discloses a comprehensive performance evaluation method of a DC high-speed switch. The method comprises an internal arc-tolerance performance detection test for detecting and determiningwhether the cauterization tolerance performance of a tested circuit breaker meets requirements, an external insulation performance detection test for detecting and determining whether the insulationmargin of the tested circuit breaker meets requirements, a DC air charging current breaking detection test for detecting and determining whether the breaking performance of the tested circuit breakermeets requirements, and a mechanical performance detection test for detecting and determining whether the mechanical reliability of the tested circuit breaker meets requirements. On the basis of the internal arc-tolerance performance detection test, the external insulation performance detection test, the DC air charging current breaking detection test, and the mechanical performance detection test, comprehensive and comprehensive performance testing and determination of the HSS can be realized to determine whether application performance requirements can be met, so that the application security is ensured.
Description
technical field [0001] The invention relates to an evaluation method, in particular to a comprehensive performance evaluation method of a DC high-speed switch. Background technique [0002] A DC high speed switch (High speed switch, HSS) is mainly used in a multi-terminal flexible DC transmission system. The purpose of configuring the DC high-speed switch is to realize the online switching of the third station of the DC system and the high-speed isolation of DC line faults, and improve the reliability and availability of the entire DC system. [0003] The DC high-speed switch generally adopts the type of open column circuit breaker, and the operating mechanism can be hydraulic or spring. In order to cooperate with the coordinated control of the multi-terminal system and realize the online input and exit of the sending end and the receiving end, the coordination requirements for the key performance parameters of the equipment are very high. Has the following characteristics:...
