It crosses busbar connector 100 to be fixedly connected with the lower end of three-phase moving contact 3, the copper bar 200 in the middle part of three-phase static contact 5 and switchgear is fixed to be connected
It connects, and three-phase moving contact 3 and 5 position of three-phase static contact correspond.Driving motor 6 is fixed on the right side of chassis 1, driving electricity
Worm screw 7 is formed in the middle part of arbor, drive motor shaft outer end is supported on 1 right side of chassis by bearing block 61.Worm gear 8 is fixed on main shaft
On 2 right ends, worm screw 7 and worm gear 8 are engaged, and 2 both ends of main shaft are respectively supported on 1 two sides of chassis.Pressure spring discharges one-way element 9 and is arranged
Between main shaft 2 and swing arm 4.
Swing arm 4 includes axle sleeve 41 and from the middle part of axle sleeve 41 outwardly extending two panels hook-type piece 42 side by side, axle sleeve 41 and main
2 middle part clearance fit of axis, so that axle sleeve 41 can be rotated around 2 axial line of main shaft.Hook-type piece first end 421 and 10 upper end of pressure spring mechanism
102 upper end of press spring base it is hinged, the longitudinal slot 423 of hook-type piece second end 422 and sliding axle mobile mechanism 11 are hinged.
Central angle alpha=110 °~114 ° of radial fan groove 423, the present embodiment are that 112 ° of its corresponding arc length reach 33mm,
Be conducive to pressure spring 101 and discharge elastic energy storage.
Pressure spring release one-way element 9 include lateral pin 91 and be symmetricly set on the 41 middle part outer peripheral surface of axle sleeve of swing arm 4 two
Item radial direction fan groove 411 passes across 2 middle part of main shaft in the middle part of lateral pin 91, and is fixedly connected with main shaft 2, and 91 both ends of lateral pin pass through axis
The radial fan groove 411 of two of set 41, makes swing arm 4 can be around 2 axis partial rotational of main shaft.
Sliding axle mobile mechanism 11 includes two sliding axles, 111, two sleeves 112 and push rod 113,112 two sides of sleeve
It is provided with longitudinal slot 114, push rod 113 passes across the longitudinal slot 114 and two sliding axles 111 of 112 two sides of sleeve, and slides with two
Axis 111 is vertically fixedly connected.Corresponding longitudinal slot 114, the hook-type piece of swing arm 4 are stretched out in the both ends end of push rod 113 respectively
The longitudinal slot 423 of second end 422 is movably hinged by 113 end of push rod with sliding axle 111 respectively.
The course of work of the invention is as follows:
As shown in figure 3, driving motor output shaft reversely rotates when separating brake, worm gear 8 is driven to rotate counterclockwise by worm screw 7, so that
Swing arm 4 rotates counterclockwise, and the longitudinal slot 423 of hook-type piece second end 422 pushes two sliding axles 111 to move down by push rod 113, and three
Phase moving contact 3 is detached from three-phase static contact 5, grounding switch tripping.Meanwhile hook-type piece first end 421 rotates counterclockwise, so that and its
Hinged press spring base 102 moves down therewith, 101 compression energy storage of pressure spring.Meanwhile secondary control component automatically controls driving motor and stops
Vehicle.
As shown in figure 4, pressure spring 101 discharges elastic energy storage after driving motor 6 stops, swing arm 4 is pushed by press spring base 102
Hook-type piece first end 421 rotated clockwise around 2 axial line of main shaft, then pushed away by the hinged push rod 113 of hook-type piece second end 421
Dynamic two sliding axles 111 move up, so that busbar connector 100 pushes three-phase moving contact 3 to move up；The one-way element 9 of pressure spring release simultaneously
Lateral pin 91 rotates clockwise 112 ° around 2 axial line of main shaft, due to limit of the slewing area by radial fan groove 411 of lateral pin 91
System, it is also restrained that three-phase moving contact 3 moves up range.Three-phase moving contact 3 is moved up stroke and is divided into two sections by the present invention, wherein first
Section is that release the pre- of elastic energy storage of pressure spring 101 moves up stroke, and second segment is the combined floodgate stroke of three-phase moving contact 3, moves up stroke in advance
The distance that three-phase moving contact 3 moves up combined floodgate can be shortened.
As shown in figure 5, driving motor output shaft rotates in the forward direction when closing a floodgate, worm gear 8 is driven to rotate clockwise by worm screw 7,
So that swing arm 4 rotates clockwise, the longitudinal slot 423 of hook-type piece second end 422 is pushed on two sliding axles 111 by push rod 113
It moves, carries out the combined floodgate stroke that three-phase moving contact 3 moves up, three-phase moving contact 3 injects in three-phase static contact 5, completes earthing switch
It closes a floodgate.
In addition to the implementation, the present invention can also have other embodiments, all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
