Embodiment Construction

[0009] As shown in the figure, a high-voltage switch cabinet grounding switch interlock device includes a wedge-shaped interlock sliding piece 2 installed on the front column 1 of the switch cabinet, and an interlock piece 3 installed in the installation box on the column. The locking slide 2 is wedge-shaped with a wide top and a narrow bottom. The wedge-shaped interlocking slide 2 can slide up and down along the front column 1; A limit piece 5 is arranged on the top, and when the grounding switch operating rod 4 rotates, it drives the limit piece 5 to rotate to block or release the wedge-shaped interlock sliding piece 2; one side of the wedge-shaped interlock slide piece 2 is against the interlock piece 3, and the wedge-shaped interlock When the locking sliding piece 2 slides down along the front column 1 of the switch cabinet, it can push the interlocking piece 3 to move backward through the wedge-shaped side, and the interlocking piece 3 is fixedly connected with the interlo...

Abstract

The invention relates to a grounding switch interlocking device for a high-voltage switch cabinet. The grounding switch interlocking device for the high-voltage switch cabinet comprises a wedge-shapedinterlocking sliding sheet which is wide at the upper part and narrow at the lower part and is mounted on the front upright column of the switch cabinet; when sliding downwards along the front upright column, the wedge-shaped interlocking sliding sheet pushes an interlocking sheet moves backwards through the wedge-shaped side edge of the wedge-shaped interlocking sliding sheet, so that the interlocking sheet can drive the interlocking mechanism of the circuit breaker of the switch cabinet to move in a linkage manner; a mounting hole matched with a grounding switch operating rod is formed in the wedge-shaped interlocking sliding sheet; the grounding switch operating rod is provided with a limiting sheet; when rotating, the grounding switch operating rod drives a limiting sheet to rotate, so that the limiting sheet can clamp or release the wedge-shaped interlocking sliding sheet; and the wedge-shaped interlocking sliding sheet is reset through a tension spring between the wedge-shaped interlocking sliding sheet and the front upright column of the switch cabinet. The grounding switch interlocking device has the advantages of simple structure, convenient operation and reliable interlocking.

Description

technical field [0001] The invention relates to an interlocking device for a grounding switch of a high-voltage switch cabinet, which is specifically applied to the technical field of high-voltage switch cabinet manufacturing and installation in the power transmission and distribution industry. Background technique [0002] In the high-voltage switchgear in the prior art, only when the circuit breaker is in the test position, the grounding switch can be switched on; on the contrary, only when the grounding switch is in the opening position, the circuit breaker can be moved from the test position to the working position. Most of the existing mechanisms have defects such as complex structure, inconvenient operation, poor reliability of interlocking, etc., and cannot meet higher safety operation requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grounding switch interlocking device of a high-voltage swi...
