真空断路器反弹对灭弧室影响 The vacuum breaker rebound affects the arc chamber 受对接式结构影响，在操动机构分合操作中，断路器的触头会发生反弹，反弹具有两种形式，一种是分闸反弹，一种是合闸反弹，两种反弹都影响断路器的运行。 Affected by butt joint structure in the operating mechanism and combination operation, circuit breaker contact will rebound, rebound has two forms, one kind is break-brake rebound, rebound is a kind of switching, both rebound effects the operation of circuit breaker. 具体危害表现： Specific damage performance: 触头烧损严重，甚至熔焊。 The contact burns badly and even melts. 波纹管经受强迫振动可能产生裂纹，使灭弧室漏气。 The corrugated tube subjected to forced vibrations may cause cracks to leak out the arc chamber. 分合闸时的冲击速度及冲击力较大发生弹跳都可能产生触头和导电杆的变形，甚至产生裂纹。 The shock velocity and the impact of the shock in the split lock can produce the deformation of the contact and the conductor, and even crack. 切合电容器组的真空断路器如发生合闸弹跳还会导致电容器的损坏。 A vacuum breaker in a capacitor group can also cause damage to the capacitor if it occurs.
