Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1-6, the utility model discloses a high-voltage board 1 with preceding lower door 2 installs earthing switch 9 in high-voltage board 1, and earthing switch 9 includes main pivot 11 and the spanner 10 of being connected with main pivot 11, lifts on or pushes down spanner 10 and can realize that main pivot 11 rotates and close a floodgate and the separating brake operation, and in this embodiment, earthing switch 9 adopts current structure.
The spanner 10 of earthing switch 9 passes through interlocking gear with the hasp 3 that preceding lower door 2 medial surface was equipped with and is connected, interlocking gear include with spanner 10 articulated gangbar 4, the one end that the spanner 10 was kept away from to gangbar 4 is articulated with locking lever 5, locking lever 5 is close to the axis of rotation 6 rotation connection on the position and the curb plate 8 of high-voltage board 1 in its middle part, and the one end rigid coupling couple 7 that gangbar 4 was kept away from to locking lever 5, and couple 7 cooperates with the hanging hole on the hasp 3.
In this embodiment, the latch 3 is welded to the inner side of the front lower door 2.
The working principle of the application is as follows: when the high-voltage side is electrified, the grounding switch 9 is in a brake-separating state at the moment, namely the wrench 10 is lifted up, the linkage rod 4 which is in a linkage state with the grounding switch 9 moves upwards, the lock rod 5 rotates clockwise, the hook 7 moves downwards, the hook 7 is hung on the lock catch 3 on the front lower door 2 which is in a closed state at the moment, the front lower door 2 cannot be opened under the high-voltage electrified condition, an overhaul worker cannot enter the front lower door, and personal safety is guaranteed.
When the high-voltage side is not electrified, namely, the maintenance state, the grounding switch 9 is in a closing state at the moment, namely, the wrench 10 is pressed down, the linkage rod 4 in a linkage state with the grounding switch 9 moves downwards, the locking rod 5 rotates anticlockwise, the hook 7 moves upwards, the hook 7 leaves the hanging buckle to realize unlocking, the front lower door 2 can be opened at the moment, and the maintenance personnel can enter to perform maintenance operation.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
