Below by accompanying drawing, operating mechanism is finished the entire work process that switch cubicle disconnects (separating brake) actuating, be described in detail:

To shown in Figure 2, operating mechanism is positioned at initial bit as Fig. 1, and first handle hole 51 and second handle hole 52 on the operator guidance panel 5 all shelters from 3 on/off switch main shafts at this moment, can't carry out the on/off switch operation to it.One end 81 of positioning linkage rod 8 is arranged in first recess 53, the other end 82 is corresponding with the circuit breaker of switch cubicle but do not enter circuit breaker this moment, positioning linkage rod 8 is rotating being hinged with frame 101, and be connected with frame 101 by an extension spring 110, the effect of the positioning linkage rod 8 that resets is played in extension spring 110.Fig. 2 is the structure chart of Fig. 1 backsight, is illustrated in initial bit, the positional structure relation between operating

axis

4 and 3 the on/off switch main shafts.

Operating axis 4 begins to clockwise rotate the opening operation that carries out switch cubicle, the end 81 that the operator guidance panel 5 that rotates drives positioning linkage rod 8 leaves from first recess 53, positioning linkage rod 8 is driven to rotate and makes the other end 82 enter (not shown) in the circuit breaker, blocks circuit breaker and prevents that circuit breaker is closed in the process that disconnects.When operating axis 4 can't rotate when stopping, as Fig. 4, shown in Figure 14, the dual-purpose spacer pin 41 on the operating axis 4 enters the first common factor a, intersects with first alignment pin 11 on the first on/off switch main shaft 1, is stopped by first alignment pin 11 and can't be rotated further.At this moment, as shown in Figure 3, first handle hole 51 on the operator guidance panel 5 is promptly corresponding with the first on/off switch main shaft 1, exposes the first on/off switch main shaft 1.This moment, the user just can carry out opening operation to the first on/off switch main shaft 1, and second handle hole 52 is not corresponding with any one on/off switch main shaft.Finish the opening operation of the first on/off switch main shaft 1 as the user after, as shown in Figure 5, the rotation of the first on/off switch main shaft 1 is switched first alignment pin 11 and is left the first common factor a, the first non-return pin 12 and enter the first common factor a and intersect the counter-rotatings that stop dual-purpose spacer pin 41 with dual-purpose spacer pin 41, shown in the dotted line among Figure 14, first alignment pin 11 leaves the first common factor a.Finish the switching of first alignment pin 11 and the first non-return pin, 12 positions relation.Dual-purpose spacer pin 41 after switching on the operating axis 4 no longer is subjected to stopping of first alignment pin 11, can be rotated further, but because the first non-return pin 12 enters the first common factor a (shown in the dotted line among the first common factor a among Figure 14), stop dual-purpose spacer pin 41 from an other side, prevent that operating axis 4 from reversing counterclockwise, make operating axis 4 can only continue to clockwise rotate and finish next step opening operation.The first on/off switch main shaft 1 is connected with following isolating switch, will descend isolating switch to disconnect in the disconnection process.

Behind the opening operation of finishing the first on/off switch main shaft 1.As shown in Figure 7, operating axis 4 continues to clockwise rotate, second spacer pin 42 on the operating axis 4 enters the second common factor b, intersect with second alignment pin 21 on the second on/off switch main shaft 2, stopped by second alignment pin 21, stop operating herein, meanwhile, as shown in Figure 6, first handle hole 51 leaves the first on/off switch main shaft 1 and second handle hole 52 is corresponding with the second on/off switch main shaft 2, expose the second on/off switch main shaft 2, the rotatable second on/off switch main shaft 2 of user's this moment carries out opening operation, and when the rotation second on/off switch main shaft 2 was finished the on/off switch operation, the second on/off switch main shaft 2 of rotation changed second alignment pin 21 and leaves from the second common factor b, the second non-return pin 22 enters outside the second common factor b, finishes the switching of second alignment pin 21 and the second non-return pin, 22 positions relation.Second spacer pin 42 after switching on the operating axis 4 no longer is subjected to stopping of second alignment pin 21, can continue to clockwise rotate, as shown in Figure 8, but because the second non-return pin 22 enters the second common factor b, stop second spacer pin 42 from an other side, prevent that operating axis 4 from reversing counterclockwise, make operating axis 4 can only continue to clockwise rotate down.The second on/off switch main shaft 2 is connected with last isolating switch, will go up isolating switch and disconnect in the disconnection process.

Afterwards, operating axis 4 continues to clockwise rotate, as shown in figure 10, dual-purpose spacer pin 41 enters the 3rd common factor c, and is crossing with the 3rd keeper 102 in the 3rd positioning component, stopped by the 3rd keeper 102, meanwhile, as shown in Figure 9, turn to the position of the 3rd on/off switch main shaft 3 with first handle hole 51 of operating axis 4 rotations, expose the 3rd on/off switch main shaft 3, the user can carry out the on/off switch operation to the 3rd on/off switch main shaft 3.And second handle hole 52 leaves the second on/off switch main shaft 2, and is not corresponding with other two on/off switch main shafts.Because in the on/off switch operation of switchgear, earthed switch is opposite on the operating sequence of on/off switch with upper and lower isolating switch, isolating switch is closed clockwise up and down, then earthed switch will disconnect counterclockwise, and isolating switch disconnects counterclockwise up and down, then earthed switch will be connected clockwise.Because the operating sequence and the reversed in order of isolating switch up and down, so rotation reversed in order of the rotation of the 3rd on/off switch main shaft 3 order and first, second on/off switch main shaft 2, in this opening operation process, first, second on/off switch is for rotating counterclockwise, and the 3rd on/off switch main shaft 3 is for clockwise rotating.Therefore, its structure is also corresponding different with the structure of first, second on/off switch.The 3rd keeper 102 is arranged on the frame, when the 3rd on/off switch main shaft 3 reverse (clockwise) rotates, locking piece 31 leaves the 3rd keeper 102, the 3rd keeper 102 under the reset response of return unit (back-moving spring) 103, leave the 3rd common factor c remove to stopping of dual-purpose spacer pin 41 make operating axis 4 can continue to clockwise rotate, simultaneously the 3rd non-return pin 32 to enter the 4th common factor d crossing with the 4th spacer pin 44, stop operating axis 4 counter-rotatings, as shown in figure 11.So far, the operation of the 3rd on/off switch main shaft is finished, closed ground switch.

After the operation of finishing 3 pairs of ground connection switch closures of the 3rd on/off switch main shaft, after operating axis 4 continues down to rotate, as shown in Figure 12 and Figure 13, second recess 54 on operating axis 4 enters second recess 54 with the positioning linkage rod 8 corresponding ends 81 of positioning linkage rod 8 that make, positioning linkage rod 8 rotates the other end 82 is left from circuit breaker, unlock, make the circuit breaker can be closed.So far, whole switchgear has been finished opening operation, and isolating switch disconnects up and down, the earthed switch conducting, and breaker closing can carry out maintenance works such as follow-up maintenance.

Otherwise, the closing course of finishing switchgear then on the basis of above-mentioned opening operation flow process reverse operating get final product.Operating axis 4 rotates counterclockwise, with an end 81 of positioning linkage rod 8 from second recess 54, eject, positioning linkage rod 8 rotates and makes the other end 82 reenter circuit breaker to prevent that circuit breaker from connecting in closing course.At first first handle hole 51 rotates corresponding with the 3rd on/off switch main shaft 3 with operating axis 4 check pins, operate the 3rd on/off switch main shaft 3 and disconnect earthed switch, second handle hole 52 is corresponding with the second on/off switch main shaft 2 with being rotated further of operating axis 4 afterwards, operate the second on/off switch main shaft, the 2 closed isolating switches of going up, first handle hole 51 is corresponding with the first on/off switch main shaft 1 with being rotated further of operating axis 4 afterwards, operate the first on/off switch main shaft, 1 closed isolating switch down, operating axis 4 is rotated further and makes an end 81 of positioning linkage rod 8 reenter first recess 53 afterwards, positioning linkage rod 8 is along with the rotation that leans of rotating indicating dial 5 makes the other end 82 leave circuit breaker, breaker closing.So far, whole closing course is promptly finished.

In closing course, the matching relationship between the spacer pin on the alignment pin of each on/off switch operating mechanism, non-return pin and the operating axis 4 is identical with above-mentioned opening operation, and just direction is opposite.Alignment pin on the on/off switch main shaft is also just opposite with the effect that non-return pin is played, the effect of non-return pin becomes the effect of alignment pin when opening operation, play and stop operating axis 4, the effect of alignment pin then becomes the effect of non-return pin when opening operation, plays the effect that prevents operating axis 4 counter-rotatings.
