Ground lead pothook with anti-misoperation mechanism

Abstract

The invention discloses a ground lead pothook with an anti-misoperation mechanism, aiming at solving the problem that when a transformer substation is switched on, the ground lead pothook is forgotten to remove to cause an accident that the transformer substation is switched on with an earth lead. The ground lead pothook comprises a left spring clamping piece (9) and a right spring clamping piece (8) which are respectively arranged in a ground lead pothook elbow (1), wherein a limit pin through hole (2) is formed in the ground lead pothook elbow (1); a limit pin (3) is movably arranged in the limit pin through hole (2); the left end of the limit pin (3) is movably connected with the right spring clamping piece (8) in a jacking way; a lockhole (5) is formed in the right end of the limit pin (3); a limit pin clamping tongue (4) is arranged on the bottom in the middle part of the limit pin (3); a limit pressure spring (7) is arranged between the top surface of the limit pin (3) and the inner side face of the ground lead pothook elbow (1); and a five-prevention lockset (6) is arranged in the lockhole (5). According to the ground lead pothook with the anti-misoperation mechanism, the switching operation correctness is improved, and the occurrence of a misoperation accident is avoided.

Description

technical field [0001] The invention relates to a grounding wire hook used in the maintenance of power transmission lines, in particular to a grounding wire hook used in the switching operation of a transformer. Background technique [0002] In the switching operation of the substation, the wire should be grounded with a ground hook to ensure the smooth progress of related work. However, after the switching operation of the substation, due to various reasons, it is often forgotten to remove the remaining grounding wire, resulting in misoperation of power transmission in the substation and causing accidents. Among the misoperation accidents over the years, the ground wire left on site, and the accident with the ground wire closing accounted for the largest proportion of accidents. How to facilitate the operation of the operator and prevent the occurrence of such accidents is a difficult problem to solve. Contents of the invention [0003] The invention provides a groun...
