具有双重移动触点的电气设备包括具有两个杠杆的返回装置

Electrical apparatus with dual movement of contacts comprising a return device with two levers
Abstract:
The invention provides electric power line switchgear (10) comprising a main movable contact (14) and a secondary movable contact (16), capable of moving along a main axis A of the switchgear (10), in which the main movable contact (14) is connected to the secondary movable contact (16) by means of a crank mechanism (20) that transforms the movement of the main movable contact (14) in one direction into a movement of the secondary movable contact (16) in an opposite direction; the switchgear being characterized in that the crank mechanism (20) comprises two levers (22, 24) mounted to pivot relative to the stationary housing (12) about respective parallel pivot axes (B, C), each lever (22, 24) being connected firstly to a respective one of the main movable contact (14) and the secondary movable contact (16), and secondly to the other lever (24, 22).
Abstract(Chinese):

本发明提供了一种电力线路开关装置（10），它包括能够沿开关装置（10）的主轴线A移动的主活动触头（14）和次级可动触头（16），主活动触头（14） ）通过曲柄机构（20）连接到次级可动触头（16），曲柄机构（20）将主动触头（14）的一个方向的移动转变成二次可动触头（16）在相反方向上的移动 ; 所述开关装置的特征在于，所述曲柄机构（20）包括安装成围绕相应的平行枢转轴线（B，C）相对于所述固定壳体（12）枢转的两个杠杆（22,24），每个杠杆（22,24） 首先连接到主可动触头（14）和次可动触头（16）中的相应一个，其次连接到另一个杠杆（24,22）。
