結構特征

1.HR3熔斷器式刀開關是熔斷器和刀開關的組合電器,具有熔斷器和刀開關的基本性能,在電路正常供電的情況下,接通和切斷電源由刀開關來擔任。當線路或用電設備過載或短路時,熔斷器的熔體燒斷,及時切斷故障電流。前操作前檢修的開關,中央有供檢修和更換熔斷器的門,主要供BDL配電屏上安裝。前操作后檢修的開關主要供BSL配電屏上安裝。側面操作前檢修的開關可以制成封閉的動力配電箱。

2.開關帶有安全擋板,并裝有滅弧室。滅弧室由酚醛布板和銅板沖制件鉚合而成。

3.開關的熔斷器固定在帶彈簧、鎖板的絕緣橫梁上,在正常運行時,保證熔斷器不脫扣,而當熔斷體因線路故障而熔斷后,只需要按下鎖板便可以很方便地更換熔斷器。
