Grounding line connecting device for power equipment

Abstract

The invention relates to a grounding line connecting device for power equipment. The grounding line connecting device comprises a line fixing member and a grounding member, and further comprises an extensible member, the bottom of the line fixing member is connected with the extensible member, the bottom of the extensible member is connected with the grounding member, the line fixing member is rectangular and is provided with a rectangular penetrating cavity in the middle, a penetrating hole is formed in each of two sides of the line fixing member and communicated with the penetrating cavity, and the penetrating holes in the two sides of the line fixing member are coaxial; a pad seat is arranged on the extensible member, positioned at the bottom end in the penetrating cavity and fixed on the inner wall of the line fixing member, the penetrating holes in the two sides of the line fixing member and the pad seat are on a same straight line, and horizontal positions of the penetrating holes are lower than horizontal position of the highest end of the pad seat; the top end of the line fixing member is provided with a threaded hole and a bolt matched with the threaded hole, and the threaded hole is positioned right above the pad seat. Through the line fixing member, a grounding line is enabled to penetrate the penetrating holes in the two sides of the line fixing member, the grounding line in the penetrating cavity is set up at the highest end of the pad seat, and the bolt compresses the grounding line by rotating the bolt, so that the grounding line fixing device is convenient to mount and demount; by arranging the extensible member, the whole structure has extensible performance.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a ground wire connection device for electric equipment. Background technique [0002] In the prior art, the casing of the power equipment and the neutral point of the transformer are generally grounded, especially the grounding of the neutral point of the transformer must be firm, but when the general grounding wire is connected, it is directly connected without other additional devices. It is very troublesome to install and disassemble, and after installation, during long-term use, due to the displacement of the equipment or the influence of other external factors, the grounding wire cannot automatically shrink well, which may cause the grounding wire to become loose or disconnected. This will lead to ground failure and affect the normal operation of the equipment. Contents of the invention [0003] In view of this, the present invention provides a ground wire connection dev...
