The invention discloses a method for evaluating the comprehensive performance of a DC high-speed switch, which includes: an internal arc-burning resistance performance detection test for detecting and judging whether the burning resistance performance of a circuit breaker under test meets the requirements; an external insulation performance detection test for Detecting and judging whether the insulation margin of the tested circuit breaker meets the requirements; DC empty charging current breaking detection test, used to detect and judge whether the breaking performance of the tested circuit breaker meets the requirements; mechanical performance testing test, used to detect and judge the tested Whether the mechanical reliability of the circuit breaker meets the requirements; through the above-mentioned four major testing tests of internal arc resistance test, external insulation performance test, DC empty charging current breaking test, and mechanical performance test, the HSS can be tested Comprehensive and comprehensive performance testing and judgment to judge whether it meets the performance requirements of use and ensure the safety of use.
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:...
