Description

多用刀闸
技术领域  多用刀闸应用于三相电和两相电的电路中。
背景技术  刀闸在三相电和两相电的应用中十分广泛,它有一个上闸口是引入端带电和一个下闸口拉下闸刀时不带电,下闸口为接出端。三相电下闸口的接出端每一项电上只能接上一根输出电线,而实际的应用确是由于电机设备过多,下闸口上有时每一项电上能接上多达三、四根电线,下闸口接线过多、保险丝电流过大成为一个不小的问题。
发明内容  本实用新型多用刀闸的目的是提供一种能够有三处接出端的三相电和两相电刀闸。
多用刀闸有一个上闸口和一个下闸口,在刀闸的左、右两侧它又分别增加了左闸口和右闸口作为两处新的接出端,每一相电也有通常使用的保险丝相连。在下闸口和左、右闸口的接出端的保险丝另一端增加了两个保险丝固定螺丝孔,原来只有一个保险丝固定螺丝孔。
一块多用刀闸由于有下闸口和左、右闸口三个接出端,它能顶三块刀闸使用,可节约电器安装面板的使用空间,降低投入成本,多用刀闸也是一个小总闸。
附图说明  本实用新型多用刀闸的平面布置图如下:
本图是三相电多用刀闸的平面布置图,图4是上闸口,图5是下闸口,图1是左闸口,图2是右闸口,图3是多根保险丝固定处。
具体实施方式  多用刀闸的结构十分简单,它比普通的刀闸增加了左闸口(1)和右闸口(2)两个接出端。在闸口接出端保险丝的另一端固定部位(3)增加了两个保险丝固定螺丝孔。多用刀闸有多根保险丝交叉经过,所以应该用绝缘胶布将保险丝包上或着使用与本项专利同日申请的另一项专利“绝缘保险丝”,以免造成连电。

Claims (3)

1.多用刀闸应用于三相电和两相电的电路中,其特征在于它增加了左闸口(1)和右闸口(2)两个接出端。
2.根据权利要求1所述多用刀闸,其特征在于左闸口和右闸口的接出线有两相电和三相电。
3.根据权利要求1所述多用刀闸,其特征在于接出端的保险丝另一端增加了两个保险丝固定螺丝孔。
