摘要
弹簧作为储能机械部件被广泛应用于高压断路器的操动机构中,尤其是操动机构中的分合闸弹簧承受负载大、运行时间长、工作环境恶劣,易发生应力松弛与疲劳断裂,严重影响高压断路器分合闸工作的稳定性与安全性。近年来,国内外众多学者针对高压断路器操动机构弹簧的失效开展了大量的研究工作,取得了诸多成效。基于弹簧操动机构的发展与工作原理,首先综述了操动机构弹簧的主要失效形式及影响因素,然后从材料选择与制造工艺角度对操动机构用弹簧的性能提升方法进行了总结,并对其状态监测方法进行了介绍,旨在为今后高压断路器操动机构用弹簧的研究和应用提供参考与借鉴。
Springs as energy storage components have been widely used in operating mechanism of high-voltage circuit breakers.Specifically,the opening and closing springs working under a high load capacity,under a poor condition for a long time,may result in their stress relaxation and fatigue fracture,under would compromise the stability and safety of high-voltage circuit breakers.Recently,numerous scholars at home and abroad have focused on the failure and prevention mechanism of springs in high-voltage circuit breakers.Based on the development and working principles of spring operating mechanisms,the main failure modes and influencing factors of springs in operating mechanisms were first reviewed.Then,performance improvement methods for springs used in these mechanisms were summarized from the perspectives of materials selection and manufacturing processes,and their condition monitoring methods were introduced.This work can provide a guidance for future research and application of springs in operating mechanism of high-voltage circuit breakers.
