Abstract
10 kV switchgear is widely used in the power system, mainly for the control and protection of power equipment. After a long period of operation, the aging of various functional components of the switchgear will seriously affect the performance of the equipment, which could lead to operation failures and production accidents easily. To reduce the accident rate of 10 kV switchgear on a large scale, it is necessary to carry out systematic life prediction and fault diagnosis of switchgear, to determine an optimal time for equipment maintenance and the best scheme for prolonging life. In this paper, a set of mechanical characteristic testing and analysis systems of circuit breakers was designed and developed. The commonly used VD4 medium voltage vacuum circuit breaker was taken as the research object, and the life limit of the VD4 circuit breaker was tested. And the key characteristic parameters such as opening and closing time, opening and closing speed, and contact overrun were collected. By analyzing the parameter changes before and after the fault, the failure modes of various parts were summarized, and the influence of replacing weak parts on the overall performance of the circuit breaker was analyzed. This study can provide guidance and a practical basis for state evaluation, fault prediction, and life extension of circuit breakers.
