结构特征

1.HR3熔断器式刀开关是熔断器和刀开关的组合电器,具有熔断器和刀开关的基本性能,在电路正常供电的情况下,接通和切断电源由刀开关来担任。当线路或用电设备过载或短路时,熔断器的熔体烧断,及时切断故障电流。前操作前检修的开关,中央有供检修和更换熔断器的门,主要供BDL配电屏上安装。前操作后检修的开关主要供BSL配电屏上安装。侧面操作前检修的开关可以制成封闭的动力配电箱。

2.开关带有安全挡板,并装有灭弧室。灭弧室由酚醛布板和铜板冲制件铆合而成。

3.开关的熔断器固定在带弹簧、锁板的绝缘横梁上,在正常运行时,保证熔断器不脱扣,而当熔断体因线路故障而熔断后,只需要按下锁板便可以很方便地更换熔断器。
