Description of drawings
A kind of switchgear that Fig. 1 provides for the utility model closes the sketch map of the interlock of door operation.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, the utility model provides a kind of switchgear to close the interlock of door operation, comprises first slide plate 4, and when door-plate 2 was in closed condition, the other end that an end of first slide plate 4 props up door-plate 2, the first slide plates 4 connected second slide plate 8.First slide plate 4 and second slide plate 8 are supported by first support 3 and second support 7 respectively, and first slide plate 4 and second slide plate 8 can move horizontally on first support 3 and second support 7 respectively.One end of first spring 6 is fastened on the median septum 5 between breaker chamber and the cable vault, and the other end is connected on first slide plate 4.When door-plate 2 was in closed condition, first spring 6 was in extended state.
On second slide plate 8, be formed with two inclined-planes.Two position-limit mechanisms move on the inclined-plane on second slide plate 8 and second slide plate 8 respectively.Each position-limit mechanism comprises roller 9, and roller 9 rolls on second slide plate 8, and roller 9 is located at the bottom of guide rod 15, and the push rod 16 that is used to prop up circuit breaker chassis 1 is located at the top of guide rod 15.The top of guide rod 15 is passed bent plate 12 and is located in the sleeve 14, and when the door-plate 2 of switchgear cut out, push rod 16 was positioned at sleeve 14.After the door-plate 2 of switchgear was opened, roller 9 rolled ramp, thereby drive push rod 16 and guide rod 15 push up under the guiding of sleeve 14.
An end that outside guide rod 15, is with second spring 11 and the 3rd spring 13, the second springs 11 from the bottom to top respectively props up bent plate 12, and the other end is fastened on the guide rod 15, and an end of the 3rd spring 13 props up push rod 16, and the other end is fastened on the guide rod 15.When the door-plate 2 of switchgear was opened, second spring 11 shrank, and after door-plate 2 cut out, 11 stretchings of second spring drove guide rod 15 and fall after rise automatically.When push rod 16 and circuit breaker chassis 1 were collided, the 3rd spring 13 shrank.
When circuit breaker chassis 1 was in test position, door-plate 2 was in opening.After door-plate 2 was opened, first spring 6 shrank, and spurs first slide plate 4 and second slide plate 8, drives roller 9 simultaneously, makes on guide rod 15 and the push rod 16 and moves, and left side push rod 16 blocks circuit breaker chassis 1, makes circuit breaker chassis 1 shake the service position from test position.
When circuit breaker chassis 1 was in the service position, door-plate 2 was in opening.After door-plate 2 was opened, first spring 6 shrank, and spurs first slide plate 4 and second slide plate 8, drives roller 9 simultaneously, makes on guide rod 15 and the push rod 16 and moves, and right side push rod 16 blocks circuit breaker chassis 1, makes circuit breaker chassis 1 shake test position from the service position.
Meanwhile, in the time of outside circuit breaker cart is pulled out to cabinet, outside transport carriage band interlock plate promotes first slide plate 4 automatically, and guide rod 15 falls after rise with push rod 16 automatically, prevents that right side push rod 16 and circuit breaker chassis 1 from producing fricting movement, handled easily.
As implied above when having realized that switchgear opens the door, circuit breaker cart can't shake and into shake out operation, improves the fail safe of product operation, and the convenience of maintenance better must guarantee the safety of products operation.
