Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] Embodiments of the high voltage vacuum circuit breaker of the present invention:

[0036] like Figure 1 to Figure 12 As shown, the high-voltage vacuum circuit breaker of the present invention includes a circuit breaker body (the circuit breaker body adopts a ZN85-40.5 high-voltage vacuum circuit breaker. Since the circuit breaker body is a prior art, it will not be described in detail here, and only shown in the figure Its static contact 4, moving contact 5 and overtravel spring) and spring operating mechanism, the spring operating mechanism includes splint type main frame 1, left splint type sub frame 2, right splint type sub frame 3, energy storage mechanism 10. Closing lock and trip mechanism 11, opening lock and trip mechanism 12, and transmission spindle mechanism 13. The transmission spindle mechanism 13 i...

Abstract

The invention discloses a spring operating mechanism and a high-voltage vacuum breaker. The spring operating mechanism comprises a frame. An energy accumulation shaft and a first drive unit for driving the energy accumulation shaft to rotate are disposed on the frame. A switch-on spring is disposed between the energy accumulation shaft and the frame. A transmission spindle in transmission connection with the energy accumulation shaft through a transmission mechanism is further disposed on the frame. The transmission spindle is located above the energy accumulation shaft, the first drive unit and the switch-on spring. The transmission spindle is provided with three transmission output ends which are respectively used for being in transmission connection with the movable contacts of a three-phase vacuum arc extinguishing chamber. The spring operating mechanism has the advantages the transmission spindle is disposed above the energy accumulation shaft, the first drive unit and the switch-on spring and is close to the three-phase vacuum arc extinguishing chamber of a breaker body, spring accumulated energy is transmitted to the transmission spindle from bottom to top, the transmission spindle directly drives the movable contacts of the arc extinguishing chamber through the three transmission output ends, transmission paths are shortened, transmission is simplified, and overall performance is increased.

Description

technical field [0001] The invention relates to a spring operating mechanism, which is matched with a 40.5kV indoor high-voltage vacuum circuit breaker and a high-voltage circuit breaker of the same type and operating power. The invention also relates to a high-voltage vacuum circuit breaker using the spring operating mechanism. Background technique [0002] Among the operating mechanisms for indoor high-voltage vacuum circuit breakers, the more common ones are still spring operating mechanisms. The spring operating mechanism uses the spring as the power element to open and close the circuit breaker. It can well achieve the power matching characteristics required by the circuit breaker, and it is reliable in operation, strong in visibility, and multi-purpose. For small and medium-sized circuit breakers, it is the direction of development. [0003] The spring operating mechanism mainly includes an energy storage mechanism, a closing lock and trip mechanism, an opening lock a...
