Embodiment 1

[0036] see Figure 8, a safety belt suspension device for overhauling a disconnector, comprising a left upright, a right upright, a left safety brace, a right safety brace and a suspension mechanism, the left upright can be connected and fixed with the left safety brace, and the right upright Can be connected and fixed with the right safety support, the lower ends of the left column, the right column, the left safety support and the right safety support can be connected and fixed on the channel steel 32, and the upper ends of the left column and the right column can be connected and fixed with the suspension mechanism ; see image 3 , the left column or the right column includes a fastening mechanism, an insulating rod 2, a movable hoop 1 and an upper column head 4, the fastening mechanism includes a groove 1, and a cylinder 8 is fixed on the wall of the upper groove. The cylinder 8 is internally threaded to connect the connecting column 7, and a round hole is opened on the u...

Embodiment 2

[0061] A safety belt suspension device for isolating switch maintenance in this embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. Some differences are: two movable hooking mechanisms are provided, which can be used by two people at the same time. Carry out maintenance operations without affecting each other's work, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to a maintenance device for electric equipment, in particular to a safety belt suspension device for maintenance of an isolating switch. Background technique [0002] GW4 and GW5 disconnectors are widely used in substations. GW4 disconnectors are mainly used in 10kV, 35kV and 110kV systems, and GW5 disconnectors are mainly used in 35kV, 66kV and 110kV systems. Various deficiencies require repair work. According to the "State Grid Corporation Electricity Safety Work Regulations", when working without scaffolding or on scaffolding without railings, and the height exceeds 1.5m, safety belts should be used, and the hooks or ropes of the safety belts should be hung on strong and firm components. Or on the wire rope specially used for hanging the safety belt, and the method of high hanging and low use should be adopted. [0003] In the maintenance process, in order to ensure the safety of the operators, it is usually necessary to inst...
