Title:
METHOD FOR EVALUATING COMPREHENSIVE PERFORMANCE OF DIRECT CURRENT HIGH-SPEED SWITCH
Document Type and Number:
WIPO Patent Application WO/2021/003774
Kind Code:
A1
Abstract:
A method for evaluating the comprehensive performance of a direct current high-speed switch, comprising: an internal arcing resistance performance detection test, used for determining whether the burning resistance performance of a tested circuit breaker meets requirements; an external insulation performance detection test, used for determining whether the insulation margin of the tested circuit breaker meets requirements; a direct current empty charge current breaking detection test, used for determining whether the breaking performance of the tested circuit breaker meets requirements; and a mechanical performance detection test, used for determining whether the mechanical reliability of the tested circuit breaker meets requirements; by means of four main detection tests including the internal arcing resistance performance detection test, the external insulation performance detection test, the direct current empty charge current breaking detection test, and the mechanical performance detection test, comprehensive performance detection can be performed for the HSS, in order to determine whether the performance requirements for use are met, and thereby ensuring the safety of use.
