Source, the cam mechanism is driven by stepper motor to be rotated；The double rocker mechanism includes the first rocking bar, connecting rod and the second rocking bar；
First rocking bar is driven for driving lever by cam mechanism, and one end of the connecting rod is connected to the end of the first rocking bar, connecting rod
The other end is connected on the second rocking bar, and second rocking bar is follower lever, and one end of second rocking bar is hinged on substrate, the
The other end of two rocking bars is extended on high-voltage switch gear；The high-voltage switch gear is swung with the second rocking bar, under the driving of stepper motor
The first rocking bar of cam mechanism driving is swung, and so as to which the second rocking bar be driven to swing, the high-voltage switch gear of the second rocking bar end of realization closes
It closes or disconnects；
The cam mechanism includes the first cam and resetting spring；First cam is driven by stepper motor to be rotated, the
The profile with the first cam engagement is provided on one rocking bar；One end of the resetting spring is connected on the first rocking bar, resets bullet
The other end of spring is connected on substrate.
Further, the cam mechanism is alternatively conjugate cam, and cooperation conjugate cam is fixedly installed on the first rocking bar
The first cam and the first rocking bar point of rotation extend outwardly be provided with cooperation conjugate cam the second cam.
Further, the swing angle of second rocking bar is 10 ° to 30 °.
The utility model has the advantage of：
1）The essence of high-voltage switch gear is realized in the utility model by the cooperation of spring operation formula cam structure and double rocker mechanism
It really swings, cam mechanism provides power by independent stepper motor, improves whole stability, is used in the utility model
Spring operation formula cam structure, compared to general high-voltage switch gear actuating structure, which can realize force-closed and structure more
Stablize.
