Embodiment Construction

[0022] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 and figure 2 As shown, the present invention mainly includes a frame, and the frame includes two side plates 18 correspondingly arranged left and right and parallel to each other, and the two side plates 18 are detachably connected by a plurality of connecting pieces.

[0024] Such as figure 1 and figure 2 As shown, the two side plates 18 are rotated to connect the operating handle 5, one end of the operating handle 5 protrudes from the side plate 18 and engages with the trigger plate 24, and the operating handle 5 can be easily driven to rotate by the trigger plate 24.

[0025] Such as figure 1 and figure 2 As shown, the operating handle 5 protrudes from the shaft portion of the side plate 18 to cover one end of the first rotating arm 14, and the other end of the first rotating arm 14 is connected to one en...

Abstract

The invention relates to the technical field of vacuum circuit breakers, in particular to a manual modular spring energy storage switching-on mechanism. The manual modular spring energy storage switching-on mechanism comprises a rack, wherein the rack comprises two side plates which are arranged in a left-right corresponding mode and are parallel to each other; an operating handle is rotatably connected between the two side plates; the shaft portion, extending out of the side plates, of the operating handle is sleeved with one end of a first rotating arm; the other end of the first rotating arm is rotatably connected with one end of a second pulling plate through a pin shaft; the other end of the second pulling plate is rotationally connected to one end of a second transmission plate of afan-shaped structure through a pin shaft; the shaft portion, extending out of the side plates, of the operating handle is sleeved with a torsion spring; and one end of the torsion spring is fixed to the side plate, and the other end of the torsion spring is clamped to the side face of the first rotating arm. According to the manual modular spring energy storage switching-on mechanism, manual switching-on can be conveniently and rapidly realized without an external power supply or in case of emergency, the operation is convenient and rapid, labor is saved, and the installation is convenient; meanwhile, the manual modular spring energy storage switching-on mechanism is further suitable for transformation and upgrading of previous same-type old equipment.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to a manual modular spring energy storage closing mechanism. Background technique [0002] At present, the vacuum circuit breaker with permanent magnet mechanism is popular among users because of its few parts, simple structure and reliable performance. In the prior art, the vacuum circuit breaker with permanent magnet mechanism automatically realizes the closing action, and cannot operate normally when there is no external power supply or in some emergency situations, which brings a lot of inconvenience to users. [0003] Therefore, it is necessary to provide a closing mechanism capable of manually closing the permanent magnet mechanism vacuum circuit breaker. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a manual modular spring energy storage closing mechanism with reas...
