Abstract

The invention discloses a mechanical jam adjusting device for a GW4 type disconnector. The mechanical jam adjusting device comprises a shell, a left hoop sliding in or out from the left side of the shell, a right hoop sliding in or out from the left side of the shell, a driving device arranged in the shell and used for driving the left hoop and the right hoop to slide in or out at the same time, and an insulation handle fixed on the shell. The device has the advantages that an operator stands on the ground, holds the base of the GW4 type disconnector through the cooperation of the shell and the left and right hoops, and then applies a force through the insulation handle to rotate the base, thus effectively protecting the personal safety of the operator; due to adoption of a chain wheel and a gear in the driving device part, the locking force between the sliding part and the left and right hoops can be ensured effectively and the looseness situation during the operation process can be avoided.

Description

technical field [0001] The invention relates to a GW4 type isolating switch mechanical jamming adjustment device. Background technique [0002] The GW4 type isolating switch is often used by power companies. Many of them have a service life of more than ten years. Due to the long operation time, the bearings under the insulators of the switch knife pillars will be corroded and stuck, causing the switch knife to fail to open. [0003] This kind of failure often occurs when the substation operator is operating, and because the switch knife is still in operation, it is not easy to adjust, and there is a risk of personnel touching the live equipment. When encountering this kind of failure, the conventional treatment method: after the switch knife equipment is out of service, the personnel stand on the ladder, open the bearing cover under the switch knife support insulator, take a flat-head screwdriver and align it with the edge of the bearing screw hole, Tap with a hammer until...
