Problems solved by technology
[0002] In large-scale power consumption places or distribution networks, a general switch is usually set as the general control, while the conventional permanent magnet vacuum circuit breaker does not have the manual closing function, and the circuit breaker can only be quickly closed by electrically operating the coil. , its defect is that in the case of power failure or failure, it cannot be closed quickly, which will bring unnecessary losses, and the existing manual closing mechanism often has manual and electric interference, and this kind of The purpose of use is often high-voltage lines or relatively dangerous power grids, so any accidents may cause serious safety accidents and heavy losses

Embodiment Construction
[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention , and are not intended to limit the present invention.
[0031] see further Figure 1 to Figure 5 , a new type of manual closing mechanism provided by the present invention will now be described. The new type of manual closing mechanism includes a bracket 1. Buckle device 41, spring energy storage device 19, touch locking device 42:
[0032] The mechanical transmission device 40 is also provided with a camshaft 8 and a one-way cam 36 that drives the camshaft 8 to rotate in one direction;
[0033] The spring energy storage device 19 includes a main shaft 15, an energy storage connecting plate 14 movabl...

The invention discloses a novel manual closing mechanism. A mechanical transmission device for transmitting a force and preventing misoperation, a self-holding tripping device used for realizing quickclosing, a spring energy storage device used for providing power for the quick closing by means of spring energy storage and a touch control locking device used for performing control to disable electric operation under manual operation so as to avoid repeated closing are arranged on a bracket. With the novel manual closing mechanism of the invention adopted, manual closing is realized under thecondition of power outage or failure, and the technical problem of power grid accidents caused by switching-on and switching-off failure due to structural mechanical jamming can be avoided.
Description
technical field [0001] The invention relates to a closing mechanism, more specifically, it relates to a manual closing mechanism matched with a permanent magnet vacuum circuit breaker. Background technique [0002] In large-scale power consumption places or distribution networks, a general switch is usually set as the general control, while the conventional permanent magnet vacuum circuit breaker does not have the manual closing function, and the circuit breaker can only be quickly closed by electrically operating the coil. , its defect is that in the case of power failure or failure, it cannot be closed quickly, which will bring unnecessary losses, and the existing manual closing mechanism often has manual and electric interference, and this kind of The purpose of use is often high-voltage lines or relatively dangerous power grids, so any accidents may cause serious safety accidents and heavy losses. Contents of the invention [0003] Aiming at the problems existing in t...
