    Abstract: 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 cupshaped 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.
    Key words: pole-mounted circuit breaker; isolating switch; capacity performance test; characteristic parameter; contact pressure
