Abstract

A switch hoisting fixture includes a first rod body and a second rod body, the first rod body and the second rod body are hollow metal sleeves, the connecting end of the second rod body is inserted in the connecting end of the first rod body, the first rod body and the second rod body are provided with at least two bolt holes located at the same straight line at the connecting ends, the first rod body and the second rod body are matched with bolts and fixed through the bolt holes, side walls of the first rod body and the second rod body are fixedly provided with clamping pieces, the clamping pieces are U-shaped structure clamping pieces, and bolt holes are arranged in mutually parallel clamping piece arms of the clamping pieces. The switch hoisting fixture provided by the invention can solve the problem that during hoisting of a porcelain bottle, since a switch contact part is not connected in a fastened manner, once the contact part is separated, a disconnecting switch is easy to lose balance, thereby causing danger.

Description

technical field [0001] The invention relates to an auxiliary installation tool for electric equipment, in particular to an auxiliary tool for hoisting an isolating switch used in a substation. Background technique [0002] Isolating switch is an outdoor high-voltage switchgear, which is used for opening and closing circuits when there is voltage and no load, and for electrically isolating electrical equipment such as high-voltage busbars and circuit breakers to be repaired from live high-voltage lines. It is currently widely used in high-voltage power system. When installing the isolating switch, first place the base assembly flat on the ground workbench, fix the porcelain bottle on the bearing seat of the base assembly with hexagonal bolts, and then fix the left and right wiring seats on the porcelain bottle respectively, and then carry out hoisting from the ground . However, in the process of hoisting, since the contact part of the knife switch is not connected and faste...
