Description

GW4-110 type isolation switch maintenance operation platform

Technical Field

The utility model relates to the technical field of electric power overhaul facilities, in particular to a GW4-110 type isolating switch overhaul operation platform.

Background

The GW4-110 type disconnecting switch is widely used in 110kV systems in 110kV substations and 220kV substations, and as shown in fig. 10, the disconnecting switch device may have various defects related to parts such as conductive parts and transmission systems after long-term operation, and needs to be overhauled. According to the relevant regulations of the national grid company electric power safety work regulations: all the operations performed at the height of the falling height reference plane 2m and above are regarded as high-altitude operations; when the scaffold works on the scaffold without a scaffold or a railing and the height exceeds 1.5m, a safety belt is used or other reliable safety measures are taken; the hook or rope of the safety belt should be hung on a firm component or a steel wire rope specially used for hanging the safety belt, and a mode of hanging the safety belt in a high mode or a low mode should be adopted.

In the maintenance process, in order to ensure the safety of the operating personnel, a hanger is usually required to be installed for fixing a safety belt. During single-phase maintenance operation, generally set up the safety belt hanger on defect looks one side framework channel-section steel, the safety belt couple is hung on the link in hanger upper end. As shown in fig. 10, in two-phase or three-phase maintenance work, considering personal safety of maintenance personnel, the length of the safety belt is limited, and generally two hangers are needed to be used in cooperation, that is, a hanger (called hanger i) is installed on a framework channel steel between a phase a and a phase B and used for completing the operation of the phase a or the phase B, then a hanger (called hanger ii) is installed on a framework channel steel between the phase B and the phase C and used for completing the maintenance operation of the phase B or the phase C, when the maintenance personnel moves from the position of the hanger i to the position of the hanger ii in work, the safety belt needs to be taken down from a hanging ring of the hanger i and moved to the position between the phase B and the phase C, and then the safety belt is hung on a hanging ring of the hanger ii, and during the process, the maintenance personnel can lose safety protection temporarily; when the hanger is transferred from the position of the hanger II to the position of the hanger I, no safety protection measures are taken. The GW4-110 type isolation switch has the advantages that the upper part of the framework is completely hollow except the upper surface of the channel steel, the position where a user can stand is very limited, and a high-place falling accident is very easy to happen when a maintainer transfers an operation position.
