Close mounting plate 7, Handle axis 8, link block 9, sealing ring 10, disc spring 11, connecting shaft 12.Manual switch mounting plate 7 is fixedly mounted on
On transformer box wall, when installation, the preformed hole no more than manual switch mounting plate 7 is opened up on transformer box wall first, later
Manual switch mounting plate 7 is welded in preformed hole.Fixed on the medial surface of manual switch mounting plate 7 there are four studs, will
Cover board 16 is fixed on stud, and disc spring 11 is mounted in swivel mount 81 later, and the outside of disc spring 11 is fixed with disc spring frame, disc spring
Frame is fixed on main bracing frame 3.Disc spring 11 uses Manual spring energy storing structure, rapidly can disconnect and connect to ensure to load
It is logical.
The outer cover of Handle axis 8 is equipped with link block 9, and Handle axis 8 can rotate in link block 9, and link block 9 is step-like
Structure, top are path section, and lower section is major diameter section, are equipped with sealing ring 10 on step surface, outer spiral shell is offered above path section
Line.When link block is installed, the perforation passed through for path section is opened up on manual switch mounting plate 7, link block 9 is worn from the bottom to top
After crossing perforation, the upper end of path section and major diameter section are divided into the two sides of manual switch mounting plate 7, and sealing ring 10 is located at manual switch
The downside of mounting plate 7.Rotation has nut 2 on external screw thread, is from top to bottom equipped between nut 2 and manual switch mounting plate 7
Limit plate 6 and travel switch mounting plate 5 make link block 9 be fastened on manual switch mounting plate 7 by the fastening effect of nut 2
On, play the role of fastening oil sealing, while nor affecting on the rotation of Handle axis 8.R slot, energy are offered in 9 path section of link block
Enough install the limit plate 6 being sleeved on link block 9 and 9 rotation stop of link block.
As shown in Figures 2 to 4, travel switch mounting plate 5 is L-shaped structure, is respectively arranged with one on two sides of L-shaped structure
Travel switch.Limit plate 6 has first support arm 61 and second support arm 62, and first support arm 61 and second support arm 62 are prolonged along the vertical direction
It stretches, while limit plate 6 has L shape turning, it is corresponding with the L-shaped structure of travel switch mounting plate 5.In use, first support arm 61
With second support arm 62 can the swing limit to handle 1 limit, it is dynamic in shaft 15 when being rocked to one of support arm
Contact 13 is connected to realization with static contact 14 and closes a floodgate, i.e., handle is in closing position, when handle is rocked to another support arm, shaft 15
On moving contact 13 and the separation of static contact 14 realize separating brake, i.e. handle is in sub-gate position.
Use process of the invention is: being swung with operating stick band fixed handle 1, handle 1 drives Handle axis 8 to revolve clockwise
Turn, the amplitude of fluctuation of handle 1 be greater than 90 ° (be about 145 ° in the present embodiment, in other embodiments, can be according to the tool of disc spring
Body structure is adjusted) and with after the cooperation of 61 block of first support arm, three groups of 11 separating brake energy storage of disc spring are completed, drive connecting shaft 12 and
Shaft 15 rapidly swing 90 ° realize moving contact 13 and static contact 14 separating brakes, handle 1 when turning to second stroke switch 41,
It pushes the front end of second stroke switch 41 to swing, issues sub-gate signal after second stroke switch 41 is pushed certain angle,
Then first stroke switch 41 continues to be pushed to handle sub-gate position by handle, and after the completion of separating brake, handle 1 is under the action of disc spring 11
Balance is realized after the certain angle of backswing.Likewise, the process that on-load switch becomes "on" position from gate-dividing state is consistent,
When combined floodgate, second support arm 62 carries out block cooperation to handle 1, and first stroke switch 42 issues switching signal.In this way, in use,
Shaft can only between first support arm 61 and second support arm 62 reciprocally swinging.
In the present embodiment, first support arm 61 and second support arm 62 constitute limited block, and limited block constitutes position limiting structure, the
The side that one support arm 61 and second support arm 62 and handle 1 contact block is stop section.In the present embodiment, handle is rotated clockwise i.e.
For reversion, rotating counterclockwise as rotating forward, the side of first support arm 61 and the contact block of handle 1 is to invert stop section, second
The side that arm 62 and handle 1 contact block is to rotate forward stop section.In other embodiments, first support arm 61 and second support arm 62 can
Think the same structure, the two of the same structure are two stop sections along the side that handle rotates at this time.In the present embodiment, hand
Handle 1 and Handle axis 8 have collectively constituted operation handle.In the present embodiment, disc spring constitutes disc spring stored energy mechanism.Handle 1 and first
Position when support arm 61 contacts block is the separating brake limit, and position when handle 1 and second support arm 62 contact block is the combined floodgate limit.
In the present embodiment, close a floodgate release refer to disc spring after the completion of combined floodgate energy storage by energy release drive moving contact with it is quiet
Contact closes a floodgate, and separating brake release refers to that disc spring releases energy after the completion of separating brake energy storage and drives moving contact and static contact separating brake.
In other embodiments, the angle between first support arm 61 and second support arm 62 according to the structure of disc spring and can turn
Axis needs the angle rotated to be changed.
