Single-person ground potential live-line defect elimination method for high-voltage connector heating defect

Abstract

The invention provides a single-person ground potential electrified defect elimination method for high-voltage connector heating defects, which comprises the following steps: a single person stands on a ground potential represented by the ground and is connected with a screw base of a heating defect treatment device by using an insulating operating rod, and a screw is rotated to move a movable pressing plate downwards, so that an occlusion jaw of the heating defect treatment device is opened; the size and the thickness of the high-pressure connector are observed, and the adjusting nut is screwed through a wrench, so that the damping spring reaches a proper compression degree; the heating defect processing device is lifted by an insulating operating rod, the occlusion jaw is aligned with the high-voltage connector, and the heating defect processing device is pushed to enable the high-voltage connector to enter the occlusion jaw; the screw rod is screwed to enable the movable pressing plate to ascend until the occlusion jaw clamps the high-pressure connector; the insulating operating rod is removed, and the heating defect processing device is left on the high-voltage connector. Only one person is needed for operation, and the matching difficulty of multi-person operation is avoided; the compression degree of the damping spring is adjusted according to the thickness of the high-pressure connector to keep sufficient elasticity, and the defect elimination effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of electric equipment defect treatment, in particular to a method for eliminating defects caused by heating defects of high-voltage joints with a single person charged with ground potential. Background technique [0002] The high-voltage joints used to connect live electrical equipment often have current-induced heating defects due to loose nuts and contact surface oxidation, which can easily cause equipment burnout and lead to power outages. [0003] Application No. 201920318802.5 is a high-efficiency treatment device for high-voltage joint heating defects, including a base, a movable platen, a screw, a damping spring, and a shunt line; the base is specifically a "U"-shaped base with an opening facing the side, "U" There is a movable pressing plate in the opening of the type base; the movable pressing plate is a tooth-shaped contact pressing plate with serrated protrusions arranged on the upper surface, and...

Problems solved by technology

However, in actual use, there are also deficiencies, specifically: (1) for some high-pressure joints with small volume and thickness, the opening degree of the occlusal jaws of the device is small, so that the compression degree of the damping spring is limited, and the spring force is insufficient. As a result, the clamping degree of the device to the high-voltage joint is not enough, and the damping spring will have insufficient elasticity after the device has been used for a long time; In this way, the jaws of the device are not easy to align with the high-pressure joint, and it is easy to touch the fastening nuts on both sides, making the installation difficult; The spacing is limited. When the device clamps the high-voltage joint, the tooth-shaped contact plate of the device is in contact with the nut gasket, resulting in only partial contact between the tooth-shaped contact plate of the device and the high-voltage joint. The contact is not sufficient, and the cooling effect is not good.
