Described isolator operating mechanism is by the first support 21 be fixed in door font in box body 5, through bottom box body 5 and the first action bars 2 of protruding upward of this first support and the 3rd action bars 24, be fixed on the backing pin 18 on the first action bars 2, the universal driving shaft 22 be connected with the first action bars 2 bottom, the first spring 19 between backing pin 18 and the first support 21, be fixed on first backing plate 28 at the 3rd action bars 24 top, the 3rd spring 27 between this first backing plate and the first support 21, to be arranged in above the first backing plate 28 and to be bearing in the first cam 29 of box body 5 by the first rotating shaft 30, the first baffle plate 1 be fixed in hilt shape on the first action bars 2 is formed,
Respectively there is a window 32 position box body 5 corresponding to the first rotating shaft 30 and the second rotating shaft 8, and described mutual interlocking gear is by being arranged in box body 5 and the slide plate 4 that two windows 32 alternately can be blocked, the extension spring 6 that connects this slide plate and driving lever 33 are formed; Slide plate 4 there is horizontal concrete chute 3, with two sliding pins 17 that this horizontal concrete chute is suitable, slide plate 4 is located on the inwall of box body 5.
For the ease of showing the operating state of earthing switch operating mechanism, respectively having in the front and back end of the second support 12 on second vertical runner 37, the 4th action bars 35 and having the 3rd vertical runner 36; The second screw rod 13 being fixed with the second direction board 14 is fixed on the second action bars 15 through the 3rd vertical runner 36 and two second vertical runners 37; The surface of the second direction board 14 is marked with " separating brake ", " combined floodgate " two states from top to down.For the ease of showing the operating state of isolator operating mechanism, respectively have first vertical runner 31 in the front and back end of the first support 21, the first screw rod 20 being fixed with the first direction board 26 is fixed on the 3rd action bars 24 through two first vertical runners 31; The surface of the first direction board 26 is marked with " combined floodgate ", " separating brake " two states from top to down.
In order to prevent artificial moving slide board by force 4, improve security reliability; This slide plate 4 is fixed with alignment pin 25, the first direction board 26 has the location notch 23 suitable with this alignment pin.
Operation principle is as follows:
Power transmission program: the lower end hook (figure acceptance of the bid is not shown) on cabinet door being fastened the 4th action bars 35, second baffle 16 moves down under the effect of the 4th action bars 35, thus makes the termination of the second rotating shaft 8 reveal (see figure 2); Make it rotate clockwise so the operating grip (not shown) being similar to box spanner can be inserted in the 4th action bars 35, the second action bars 15 drives the second direction board 14 to move down by the second screw rod 13 under the effect of the second cam 9; So " separating brake " mark on this second direction board is just in gate-dividing state by the show hole (not shown) display earthing switch operating mechanism on box body 5.Meanwhile, slide plate 4 moves right (see figure 1) under the traction of extension spring 6; After described operating grip takes off, slide plate 4 continues to move to right and is blocked by that window 32 corresponding with the second rotating shaft 8 position, opens that window 32 corresponding with the first rotating shaft 30 position simultaneously.
Operating grip be inserted in the first rotating shaft 30 and rotate clockwise, the 3rd action bars 24 drives the first direction board 26 to move down by the first screw rod 20 under the effect of the first cam 29; So " combined floodgate " mark on this first direction board is just in "on" position by the another one show hole (not shown) display isolator operating mechanism on box body 5.Now vacuum circuit-breaker (not shown) is closed a floodgate, and the connecting lever (not shown) on it drives the first baffle plate 1 to move down by universal driving shaft 22, first action bars 2, thus is blocked the termination of the first rotating shaft 30; Meanwhile, alignment pin 25 snaps in the location notch 23 on the first direction board 26 and is locked by slide plate 4, thus can avoid artificial moving slide board 4 by force and cause a serious accident.Power transmission has operated, the door locking of charged isolation ward, isolating switch on-load deciliter.
Power-off program: by vacuum circuit-breaker separating brake, connecting lever (not shown) on it is driven on the first baffle plate 1 by universal driving shaft 22, first action bars 2 and moves, operating grip be inserted in the first rotating shaft 30 and rotate counterclockwise, 3rd action bars 24 drives the first direction board 26 to rise by the first screw rod 20 under the effect of the 3rd spring 27, and " separating brake " mark on this first direction board is just in gate-dividing state by another described show hole display isolator operating mechanism.After alignment pin 25 and location notch 23 unlock, manually slide plate 4 is moved to left and shelter from that window 32 corresponding with the first rotating shaft 30 position; Operating grip be inserted in the second rotating shaft 8 and rotate counterclockwise, second action bars 15 drives the second direction board 14 to rise by the second screw rod 13 under the effect of the second spring 11, and " combined floodgate " mark on this second direction board is just in "on" position by described show hole display earthing switch operating mechanism.Power-off completes, and can open cabinet door (not shown) and enter isolation ward and carry out maintenance operation.
