Abstract

The invention discloses a switch cabinet safety isolation device and method. The device comprises a first support rod and a second support rod. The first support rod and the second support rod are arranged on two opposite sides of a switch cabinet. The upper end of the first support rod is higher than the top of the switch cabinet. The upper end of the second support rod is higher than the top ofthe switch cabinet. The first support rod comprises a first upper strut and a first lower strut. The first upper strut and the first lower strut are hinged. The second support rod comprises a second upper strut and a second lower strut. The second upper strut and the second lower strut are hinged. The first lower strut is connected with the switch cabinet. The first upper strut is provided with atelescopic isolation belt. The second lower strut is connected with the switch cabinet. The second upper strut is provided with an isolation belt buckle. One end of the telescopic isolation belt is buckled with the isolation belt buckle. According to the switch cabinet safety isolation device and method, safety isolation is realized during top operation of the switch cabinet; and the device is convenient for storage and carrying.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance tools, in particular to a switch cabinet safety isolation device and method. Background technique [0002] Switch cabinets are widely used electrical equipment in power systems, especially in 35kV and 10kV voltage levels. Therefore, the maintenance work of the switchgear is particularly important. However, due to its fully enclosed nature, the inside of the switchgear cannot be seen at ordinary times, and accidents are prone to occur. Therefore, safety measures should be taken before the switchgear is overhauled to ensure the safety of the staff. At present, the safety measures of the switchgear in the substation include ordinary telescopic fences, red and white belts, etc. These safety measures are mainly aimed at the work of the switchgear on the ground, which can isolate live equipment and protect the personal safety of the staff. But when the workers work on the top of t...
