Abstract

The invention relates to a fixing method and device for a high-voltage test wiring, and belongs to the technical field of series resonance withstand voltage tests in electrical power engineering. The technical scheme is that a base (5) is square; four dowel inserting holes (6) are respectively formed in four corners of the base (5); a circular sleeve (2) is arranged in the center of the base (5); U-shaped handles (1) and an earth point (4) are arranged on the base; dowels (7) are matched with the dowel inserting holes (6); the circular sleeve (2) is perpendicular to the base; an insulating rod is inserted into the circular sleeve and is connected with the circular sleeve in a fastening manner; a fastening bolt (3) is arranged on the side wall of the circular sleeve, and is connected with the earth point through a wire; the U-shaped handles adopt U-shaped structures; two end points of the U-shaped handles are hinged to the base. A series resonance withstand voltage test meets the standardized and normalized requirement, the high-voltage test wiring fixing time is effectively shortened, the series resonance withstand voltage test efficiency is improved, and potential safety hazards to personnel, equipment and peripheral equipment are eliminated.

Description

technical field [0001] The invention relates to a fixing method and device for high-voltage test wiring, and belongs to the technical field of electric power engineering series resonance withstand voltage test. Background technique [0002] At present, in order to ensure the safe and reliable operation of power cables in the power grid, the cable series resonance withstand voltage test must be carried out before the power cables are put into use. In the process of cable series resonance withstand voltage test, since the test wiring voltage drawn by the reactor ranges from tens of kilovolts to hundreds of kilovolts, if the test wiring is not connected firmly, there will be safety hazards for the test personnel and surrounding equipment. Cause trouble. There is no series resonance high-voltage lead wire fixing device in the background technology. At the series resonance test site, when the distance between the reactor and the tested product is relatively close, the test perso...
