Description
Technical field
The present invention relates to electric device field, more particularly to a kind of high-voltage switch gear powder operation device.
Background technology
Occur a kind of high-pressure vacuum switch, including housing and three horizontally disposed vacuum in housing on the market
Arc-chutes, and realize that divide-shut brake acts using spring operation formula driving mechanism, it is disadvantageous in that：Spring operation formula driving mechanism component
It is more, easily break down, and since spring operation formula driving mechanism volume is larger, need to be arranged on housing exterior walls, cause overall account for
It is more with space, cost is not only increased, also brings a variety of inconvenience to transport and installation.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high-voltage switch gear powder operation device, can solve general height and press off
Close the problem of powder operation device is complicated, and operation lifetime is low, and security is low.
In order to solve the above technical problems, the technical scheme is that：A kind of high-voltage switch gear powder operation device, its innovative point exist
In：Including substrate, high-voltage switch gear and operating mechanism；The operating mechanism is disposed on the substrate, the output terminal connection of operating mechanism
There is high-voltage switch gear；
The operating mechanism includes cam mechanism and crank and rocker mechanism；The cam mechanism is the power of crank and rocker mechanism
Source, the cam mechanism are rotated by driving stepper motor；The crank and rocker mechanism includes crank, connecting rod and rocking bar；The song
Handle is driven for driving lever by cam mechanism, and one end of the connecting rod is connected to the end of crank, and the other end of connecting rod, which is connected to, to be shaken
On bar, the rocking bar is follower lever, and one end of the rocking bar is hinged on substrate, and the other end of rocking bar extends to high-voltage switch gear
On；The high-voltage switch gear is swung with rocking bar, crank-swinging is driven in the driving lower cam mechanism of stepper motor, so as to drive rocking bar
Swing, realize closure or the disconnection of the high-voltage switch gear of rocking bar end.
Further, the cam mechanism is conjugate cam, and first that cooperation conjugate cam is fixedly installed on crank is convex
Take turns and stretch out in the crank point of rotation and be provided with the second cam for coordinating conjugate cam.
Further, the swing angle of the rocking bar is 80 ° to 100 °.
Further, the cam mechanism is alternatively single cam spring structure, including cam and extension spring, extension spring
One end be connected on crank, be fixedly installed on crank coordinate cam roller.
The advantage of the invention is that：
1）The accurate of high-voltage switch gear is realized in the present invention by the cooperation of conjugate cam and crank and rocker mechanism to swing, cam machine
Structure provides power by independent stepper motor, improves overall stability, the conjugate cam structure used in the present invention, phase
Than realizing that force-closed structure is more stablized in general spring operation formula structure, conjugate cam.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a kind of high-voltage switch gear powder operation device of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described scope.
