Research on Life Cycle Model of Mechanical Components of High Voltage Circuit Breakers

高压断路器作为保证电网安全运行的重要设备,主要起到控制和保护设备的作用。随着使用时间的增加,机械结构、触头磨损,分合闸二次机构等故障问题日益凸显,此类问题导致断路器相关部件老化、损坏,引起断路器运行失常,甚至影响电网安全稳定运行。因此文章建立了高压断路器机械部件生命周期模型,通过该模型可以更精准的预测断路器剩余生命周期,帮助检修人员及时发现高压断路器存在的隐患,将隐患从根源上消灭,防患于未然;检修人员可以在生命周期模型的结果上判断是否须要更换高压断路器,尽可能降低用户的停电时间,提高设备利用率达到节约费用的作用。

As an important equipment to ensure the safe operation of the power grid,the high-voltage circuit breaker mainly plays the role of control and protection equipment.With the increase of use time,the failure problems such as mechanical structure,contact wear,and opening and closing secondary mechanism become increasingly prominent.Such problems lead to the aging and damage of circuit breaker related components,causing the circuit breaker to oper‐ate abnormally,and even affecting the safe and stable operation of the power grid..Therefore,this paper establishes the life cycle model of the mechanical parts of the high-voltage circuit breaker.Through this model,the remaining life cycle of the circuit breaker can be predicted more accurately,which can help the maintenance personnel to find the hidden dan‐gers of the high-voltage circuit breaker in time,eliminate the hidden dangers from the root,and play a preventive role.Before it happens;maintenance personnel can judge whether the high-voltage circuit breaker needs to be replaced based on the results of the life cycle model,so as to reduce the user's power outage time as much as possible,and improve the equipment utilization rate to save costs.
