Embodiment Construction

[0020] according to Figure 1-8The specific structure of the present invention will be described in detail. The installation and specific operation requirements of the device are basically the same as those of the existing spring operating mechanism. It includes the main box and the terminal 1 assembled on it, the energy storage motor assembly 3, the travel switch assembly 4, the auxiliary switch 5, the energy storage cam assembly with the energy storage crank arm 28 at both ends, and the closing arm hanging on the crank arm. Brake energy storage spring 2, energy storage indicator assembly 6, manual opening and closing button 7, opening and closing indicating assembly 8, closing release 9, opening and overcurrent release 10, transmission linkage assembly 11 , the interlocking mechanism connected with the transmission link assembly 11, the counter 12 and the like. Among them, the main chassis is mainly composed of left and right mounting plates 19, 27, etc., and the main bear...

Abstract

The invention is a miniaturized spring control mechanism, comprising main machine case, energy storage electric machine component, energy storage cam component, and drive link rod component, and its technical characters lie in that: there are mutually reverse free-wheeling clutches on the in-gear box segment of the output spindle in the energy storage electric machine component, the worm wheel of the worm gear free-wheeling clutch engages with the worm shaft of the socket handgrip, the gear of the gear of the gear free-wheeling clutch engages with the driving gear of the electric machine, the small gear arranged on the outside-gear box segment of the output spindle engages with the large gear mounted on the cam spindle, the inner circle of the large gear is provided with reverse stopping flywheel, hinged with the pawl on the flywheel, and the pawl is controlled by elastic pin and striking block to be inserted in or depart from the inner circle of the large gear. The invention has the characters of reasonable component distribution, compact structure, small bulk, etc.

Description

technical field [0001] The invention relates to a mechanical transmission device for closing and opening of a vacuum circuit breaker, in particular to a miniaturized spring operating mechanism. It has strong versatility and can be used to match circuit breakers in 3.6KV~40.5KV three-phase AC and 50HZ power grids. It can not only match VKP series and VS1 series central switches, but also ZN28-12, ZN85B-40.5 and ZW37-40.5 Series indoor and outdoor vacuum circuit breakers and side-mounted circuit breakers. Therefore, the operating mechanism is not only suitable for the operating mechanism of the circuit breaker on the fixed switch cabinet, but also suitable for the operating mechanism of the circuit breaker on the removable central cabinet. Background technique [0002] At present, with the continuous improvement of the technical level of AC high-voltage circuit breakers and the market demand, especially the rapid development of 12kV class vacuum circuit breakers, the market h...
