Abstract
Implementations of the subject matter described herein provide a switching apparatus including an energy storage changement mechanism that can realize the main shaft energy storage and direction changement by using only one solenoid. Furthermore, the switching apparatus can be adopted in both two position ATS and three position ATS to satisfy different application scenarios or different market requirements. In addition, all transfers can be achieved by independent manual and electric operation, and each transfer action only requires powering a single solenoid.
Claims15
A switching apparatus for use in a switch, comprising:
- a solenoid including a moving core;
- a support plate including a V-shaped groove and coupled to the solenoid;
- a main shaft rotatably arranged on the support plate;
- a push rod operable to cause a rotation of the main shaft, a first end of the push rod being connected to the moving core, a second end of the push rod being coupled to the V-shaped groove and movable within the V-shaped groove in association with a movement of the moving core;
- a main spring coupled between the main shaft and the solenoid, and operable to facilitate the main shaft to reach a rotational position corresponding to an operating position of the switch;
- a swinging rod arranged on the main shaft, the swinging rod including two guiding edges for determining a movement direction of the second end within the V-shaped groove, based on a contact of the second end to a first guiding edge or a second guiding edge;
- and
- a secondary spring coupled between the main shaft and the swinging rod, the secondary spring being operable to cause the swinging rod to rotate in association with the rotation of the main shaft.
