The specific embodiment of on-load switch of the invention, as shown in Figures 1 to 7, wherein 1 is handle, 2 is nut, based on 3
Body support frame, 4 is travel switch, and 5 is travel switch mounting plate, and 6 is limiting plate, and 7 is hand switch installing plate, and 8 is Handle axis,
9 is contiguous block, and 10 is sealing ring, and 11 is disc spring, and 12 is connecting shaft, and 13 is moving contact, and 14 is static contact, and 15 is rotating shaft, and 16 are
Cover plate.Limiting plate 6 includes first support arm 61 and second support arm 62, and swivel mount 81 is fixed with Handle axis 8.
Hand-operating device includes handle 1, nut 2, travel switch 4, travel switch mounting plate 5, limiting plate 6, opens manually
Close installing plate 7, Handle axis 8, contiguous block 9, sealing ring 10, disc spring 11, connecting shaft 12.Hand switch installing plate 7 is fixedly mounted on
On transformer box wall, during installation, the preformed hole of no more than hand switch installing plate 7 is opened up on transformer box wall first, afterwards
Hand switch installing plate 7 is welded in preformed hole.Four studs are fixed with the medial surface of hand switch installing plate 7, will
Cover plate 16 is fixed on stud, and disc spring 11 is arranged in swivel mount 81 afterwards, and the external stability of disc spring 11 has disc spring frame, disc spring
Frame is fixed on main bracing frame 3.Disc spring 11 uses Manual spring energy storing structure, to ensure that load can rapidly disconnect and connect
It is logical.
The outer cover of Handle axis 8 is equipped with contiguous block 9, and Handle axis 8 can be rotated in contiguous block 9, and contiguous block 9 is step-like
Structure, top is path section, and lower section is big footpath section, and sealing ring 10 is provided with step surface, and outer spiral shell is offered above path section
Line.When contiguous block is installed, the perforation passed through for path section is opened up on hand switch installing plate 7, contiguous block 9 is worn from the bottom to top
After crossing perforation, the upper end of path section and big footpath section are divided into the both sides of hand switch installing plate 7, and sealing ring 10 is located at hand switch
The downside of installing plate 7.Rotation has nut 2 on external screw thread, is from top to bottom provided between nut 2 and hand switch installing plate 7
Limiting plate 6 and travel switch mounting plate 5, by the fastening effect of nut 2, make contiguous block 9 be fastened on hand switch installing plate 7
On, play a part of to fasten oil sealing, while nor affecting on the rotation of Handle axis 8.R grooves, energy are offered in the path section of contiguous block 9
The limiting plate 6 being sleeved on contiguous block 9 is enough set to be installed with the rotation stop of contiguous block 9.
As shown in Figures 2 to 4, travel switch mounting plate 5 is L-shaped structure, and one is respectively arranged with two sides of L-shaped structure
Travel switch.Limiting 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
Stretch, while limiting plate 6 has L-shaped turning, the L-shaped structure with travel switch mounting plate 5 is corresponding.When using, first support arm 61
The swing limit of handle 1 can be limited with second support arm 62, it is dynamic in rotating shaft 15 when one of support arm is rocked to
Contact 13 connects realization with static contact 14 and closes a floodgate, i.e., handle is in closing position, when handle is rocked to another support arm, rotating shaft 15
On moving contact 13 and static contact 14 separate realize separating brake, i.e. handle be in sub-gate position.
Use process of the invention is：Swung with action bars band fixed handle 1, handle 1 drives the dextrorotation of Handle axis 8
Turn, the amplitude of fluctuation of handle 1 is more than 90 °（It is for about 145 ° in the present embodiment, in other embodiments, can be according to the tool of disc spring
Body structure is adjusted）And after coordinating with the block of first support arm 61, three groups of separating brake energy storage of disc spring 11 are completed, drive connecting shaft 12 and
Rotating shaft 15 swings rapidly 90 ° of separating brakes for realizing moving contact 13 and static contact 14, handle 1 when the second travel switch 41 is turned to,
Promote the front end of the second travel switch 41 to swing, sub-gate signal sent after the second travel switch 41 is promoted certain angle,
Then the first travel switch 41 continues to be pushed to handle sub-gate position by handle, and after the completion of separating brake, handle 1 is in the presence of disc spring 11
Balance is realized after the certain angle of backswing.Likewise, the process that on-load switch is changed into "on" position from gate-dividing state is consistent,
During combined floodgate, second support arm 62 carries out block cooperation to handle 1, and the first travel switch 42 sends switching signal.So, when using,
Rotating 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 contact block with handle 1 is stop section.In the present embodiment, handle is rotated clockwise i.e.
It is reversion, rotates counterclockwise as rotating forward, the side that first support arm 61 contacts block with handle 1 is reversion stop section, second
Arm 62 contacts the side of block with handle 1 to rotate forward stop section.In other embodiments, first support arm 61 and second support arm 62 can
Think same structure, now the two of same structure are two stop sections along the side that handle is rotated.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 during the contact block of support arm 61 is the separating brake limit, and position when handle 1 contacts block with second support arm 62 is the combined floodgate limit.
In the present embodiment, combined floodgate release refer to disc spring after the completion of combined floodgate energy storage by energy discharge drive moving contact with it is quiet
Contact closes a floodgate, and separating brake release refers to that energy is discharged drive moving contact and static contact separating brake by disc spring after the completion of separating brake energy storage.
In other embodiments, the angle between first support arm 61 and second support arm 62 can according to the structure of disc spring and turn
Axle needs the angle for rotating to be changed.
