Visualization device used for observing on-off state of disconnecting link contact

Abstract

The invention relates to the technical field of electric power tools, in particular to a visualization device used for observing an on-off state of a disconnecting link contact. The visualization device used for observing the on-off state of the disconnecting link contact comprises a power device and a laser device electrically connected with the power device, the laser device comprises a laser seat and a laser emitter arranged on the laser seat, the laser seat is provided with a fixing structure used for fixing the laser device to a shell of an observing hole of a disconnecting link contact,and the laser emitter is provided with an optical lens used for amplifying light beams. The device is simple in structure, laser beams can be emitted into the observing hole of the disconnecting linkcontact through the laser emitter, through the arrangement of the fixing structure arranged on the laser seat, the laser device can be fixed to the shell of the observing hole of the disconnecting link contact, it can be saved that a worker holds a flashlight with a hand to make the observing hole illuminated, the working efficiency is improved, and it can be avoided that when the worker holds theflashlight with a hand to make the observing hole illuminated, a suitable point for supporting the body cannot be found so as to cause the risk of high-altitude falling.

Description

technical field [0001] The invention relates to the technical field of power tools, and more particularly, to a visualization device for observing the on-off state of a knife switch contact. Background technique [0002] Pinggao ZF5T-126 GIS knife switch and grounding knife switch are phase-separated structures. When checking the opening and closing positions of the knife switch, you can only check from the indicator and the knife switch by turning the arm. It is very difficult to check if the phase is not in place, so the manufacturer has equipped observation holes on the contacts of the knife switch and the grounding knife switch for opening and closing. The existing detection method is: one person uses a flashlight to inject strong light from different angles on one side, and the other person checks whether the light is transmitted through the observation hole on the other side. Usually on-site actual operation encounters the following problems: first, two people are req...

AI Technical Summary

Problems solved by technology

Usually on-site actual operation encounters the following problems: first, two people are required to cooperate to complete the detection of the knife switch state; the second phase B observation hole is between phase A and phase C, and the position is very narrow, and the operation of the flashlight by the operator is difficult. There are certain difficulties, and the judgment time is relatively long; third, some observation holes are located at a height of 3 to 5 meters above the ground. support point, there is a considerable risk of falling
