Title:
THREE-STATION MECHANISM OF LOAD SWITCH
Document Type and Number:
WIPO Patent Application WO/2019/165812
Kind Code:
A1
Abstract:
The present invention provides a three-station mechanism of a load switch, comprising a rack. A grounding switch operation device, a closing switch operation device, and a three-station output device are provided on the rack. The three-station output device comprises an output shaft sleeve and a first crank arm which are rigidly connected. The output shaft sleeve and the rack form a rotary fit. A differential plate is provided on one side of the first crank arm. A first sliding groove is formed in the differential plate. A first drive pin is provided on the other side of the first crank arm. A first connecting rod is rotatably connected to the first drive pin. When a spring energy storage device rotates over a maximum energy storage position, the stored energy is released so as to allow a main switch operation device to rotate continuously, and in this case, the main switch operation device drives the three-station output device to rotate by means of the first connecting rod and the first drive pin so as to output a torque. The present invention can achieve three-station switching operations of closing-opening-grounding by means of two input stations and one output station, is compact in structure, and is easy to use.
