摘　　要：对带隔离开关的户外柱上断路器而言,容量性能试验要求为过程中不能发生真空灭弧室触头和隔离开关触头打火或熔焊现象。从真空灭弧室触头的选型、断路器机械特性参数的调试、隔离开关触头形式的选择、隔离开关触头压力的调校四个方面,通过多次容量性能试验的摸底测试,分别提出了真空灭弧室触头采用杯状纵磁结构触头,机械特性调试参数满足灭弧室的技术参数,隔离开关触头采用线接触形式,及隔离开关触头压力值控制在(185±25)N的技术关键点,并对真空灭弧室的生产和隔离开关触头的压力值也提出了控制措施,为柱上断路器的器件选型、关键工艺控制、质量管控等提供了参考。For an outdoor pole-mounted circuit breaker with isolating switch,test requirements are that the contact of vacuum interrupter and isolating switch cannot be ignited or fused.This paper discussed the selection of vacuum interrupter contacts,the adjustment of the mechanical characteristic parameter of the circuit breaker,the contact types of the disconnector selection,and the adjustment of the contact pressure of the disconnector.Based on the capacity performance test this study proposed four suggestions:the contact of vacuum interrupter should use cup-shaped longitudinal magnetic structure,the adjustment parameters of mechanical characteristics have to meet the technical parameters of arc interrupter,the isolating switch uses the line contact form,and the(185±25)N is the technical point of the contact pressure of isolating switch.In addition,this paper proposed the control measures for the production of the vacuum interrupter and the pressure value of the contact of the isolating switch.It provides a reference for the component selection of the pole-mounted circuit breaker,the key-process control and the quality control of the pole-mounted circuit breaker,etc.
