Problems solved by technology

[0004] However, in the above-mentioned synchronous operation process, since the switching device requires a large operating force when passing through the dead point position, in the process of transmitting the rotational motion from the first drive shaft 74 to the second drive shaft 84, the first drive shaft 74 needs to withstand the operating force that can operate the two switching devices, and the operating end 742 of the first drive shaft 74 is far away from the second drive shaft 84, resulting in a long transmission distance of the rotational motion

Abstract

The invention provides a linkage assembly of a switching device set, wherein the switching device set comprises a first switching device (10), a second switching device (20) and a main driving shaft (32) which rotatably penetrates through the first switching device and the second switching device. The main driving shaft comprises a first driving shaft (12) and a second driving shaft (22) which can be coaxially connected with the first driving shaft. The linkage assembly comprises an operation shaft (42), a first linkage member (44) and a second linkage member (34). The first linkage member can be connected with the operation shaft and rotates together with the operation shaft. The second linkage member can be connected with the main driving shaft of the switching device set and rotates together with the main driving shaft. The second linkage member is arranged at the connection part between the first driving shaft and the second driving shaft and can be transmissibly connected with the first linkage member. By means of the first linkage member and the second linkage member, rotation of the operation shaft can drive the main driving shaft to rotate. The linkage assembly can improve operation synchronism of the switching device set.

Description

technical field [0001] The invention relates to a linkage assembly, in particular to a linkage assembly of a switching device group. The present invention also relates to a switching device set having the above-mentioned linkage assembly. Background technique [0002] In the switching device, by operating the drive shaft to switch between the open position and the closed position, the drive shaft is driven to make the movable contact contact and separate from the fixed contact, thereby controlling the switching device to be closed or disconnected, so as to realize the on-off of the power supply line electric control. [0003] When it is necessary to realize the synchronous operation of two switching devices, due to the limitation of structural arrangement, such as figure 1 As shown, the two switching devices of the general switching device group are arranged up and down, and the transmission shaft 72 of the upper switching device 70 and the transmission shaft 82 of the low...
