Problems solved by technology

[0002] The current vacuum circuit breaker spring operating mechanism generally only has one closing position and one opening position, so that it can only control the on-off of one circuit in the circuit. If you want to control the on-off of two circuits, you need to use two circuit breakers. Two vacuum circuit breakers are expensive and cumbersome to use. Therefore, there is an urgent need for a double-closing position spring operating mechanism with two closing positions.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail:

[0020] Such as Figure 1-7 As shown: the present invention provides a double closing position spring operating mechanism, which includes a frame 1, a right closing input shaft 2 and a left closing input shaft 3 arranged on the frame 1, and the right closing input shaft 2 is provided with a first cam 4 linked with the shaft, and the right closing input shaft 2 is also connected with a first spring energy storage mechanism 5, and the spring energy storage mechanism 5 includes an energy storage spring, a ratchet, a torque transmission member, etc., and the spring The energy storage mechanism 5 belongs to common knowledge in the art, so it will not be described in detail here. The frame 1 is also provided with a first crank arm 6 that cooperates with the first cam 4, and one end of the first crank arm 6 is rotatably connected to the frame 1. , and this end...

Abstract

The invention provides a double-switching-on position spring operation mechanism, comprising a left switching-on input shaft and a right switching-on input shaft. By adoption of the double-switching-on position spring operation mechanism, two switching-on positions including a left switching-on position and a right switching-on position can be arranged on one spring operation mechanism, the double-switching-on position spring operation mechanism is simple in structure and convenient to operate, and is high in reliability since a situation of tripping of the two switching-on positions does not occur.

Description

Technical field: [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to a double closing position spring operating mechanism for vacuum circuit breakers. Background technique: [0002] The current vacuum circuit breaker spring operating mechanism generally only has one closing position and one opening position, so that it can only control the on-off of one circuit in the circuit. If you want to control the on-off of two circuits, you need to use two circuit breakers. Two vacuum circuit breakers are expensive and cumbersome to use. Therefore, there is an urgent need for a double closing position spring operating mechanism with two closing positions. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects and provide a double closing position spring operating mechanism with two closing positions. [0004] The technical solution provided by the present inve...
