Abstract

SF6 high-voltage circuit breaker is the key equipment that ensures the safe and stable operation of the power grid. The mechanical characteristics test is the main means which can effectively evaluate the operating state of its mechanism. Starting with the difference comparison in the type and structure of circuit breakers and following with the common skill on the test site

the differences between the action time measurement principles

the speed parameters definition algorithms and the closing resistance input modes of each type of circuit breakers is systematically compared in this paper;as a result

the essence of mechanical characteristics test is fully uncovered. Based on the summary of research and development status of the relevant test instruments at home and abroad

the best on-site test scheme is proposed. Finally

after untangling the defect analysis and recognition technologies

the actual needs and development path of intelligent evaluation scheme of circuit breaker mechanism operation status is analyzed.
