(3)闸刀开关技术参数与选择
闸刀开关种类很多,有两极的(额定电压250V)和三极的(额定电压380V),额定电流由10A至100A不等,其中60A及以下的才用来控制电动机。常用的闸刀开关型号有HK1、HK2系列。表1-1列出了HK2系列部分技术数据。
正常情况下,闸刀开关一般能接通和分断其额定电流,因此,对于普通负载可根据负载的额定电流来选择闸刀开关的额定电流。对于用闸刀开关控制电机时,考虑其起动电流可达(4-7)倍的额定电流,选择闸刀开关的额定电流,宜选电动机额定电流的3倍左右。
(4)使用闸刀开关时应注意:
·将它垂直的安装在控制屏或开关扳上,不可随意搁置;
·进线座应在上方,接线时不能把它与出线座搞反,否则在更换熔丝时将会发生触电事故;
·更换熔丝先拉开闸刀,并换上与原用熔丝规格相同的新熔丝,同时还要防止新熔丝受到机械损伤;
·若胶盖和瓷底座损坏或胶盖失落,闸刀开关就不可再使用,以防止事故。
