Problems solved by technology

[0002] There is a risk of accidents when substation workers operate the GW5A-66 isolating switch. The reason is that the GW5A-66 isolating switch has the risk of sudden fracture of the porcelain pillar, and the broken porcelain pillar 9 (see Image 6 ) naturally slides under the action of gravity, and the live wire swings naturally, which is easy to touch the staff below it. The staff run in a panic and cause step voltage induction casualties, or directly touch the 66 kV live wire, causing electric shock casualties , At the same time cause grid (system grounding, discharge, etc.) accidents

Embodiment Construction

[0018] Such as Figure 1-6 As shown, the isolation switch operation safety protection device includes two brackets 1, the brackets 1 are welded by two horizontal square tubes 101 and two vertical square tubes 102, and the two horizontal square tubes 101 are respectively equipped with The hoop 2 fixed together with the cement rod 8 below the isolating switch, and the two vertical square tubes 102 of the support 1 are respectively hinged to the insulating guardrail 3 by hinges 4, and the insulating guardrail 3 is a grid structure. The bracket 1 and the insulating guardrail 3 are respectively selected from high-quality rigid materials and insulating materials with high strength and toughness, and have tough deformation resistance. The two opposite insulating guardrails 3 on the two supports 1 are connected by a plug 6 . The insulating guardrail 3 is provided with a socket 5, and the socket 5 is provided with a limiting groove 7, so as to cooperate with the bolt 6 to achieve stab...

Abstract

An operation safety guard device for a disconnecting switch is characterized in that the safety guard device comprises two supports, each support is formed by connecting two transverse square tubes and two longitudinal square tubes in a fastening mode, the two transverse square tubes of each support are respectively provided with a hoop used for being fixed to a cement rod below the disconnecting switch, the two longitudinal square tubes of each support are respectively hinged to an insulating guardrail through a hinge, and the two opposite insulating guardrails on the two supports are connected through a plug pin. With the operation safety guard device for the disconnecting switch, workers can be protected in an annular mode while movement space for normal operation is provided for the workers, operation safety of the workers at a transformer substation is guaranteed, electric shock injuries and deaths and other power grid accidents are avoided for personnel, and the operation safety guard device for the disconnecting switch is simple in structure and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a substation safety protection device, in particular to an isolation switch operation safety protection device, which is especially suitable for the switching operation of a GW5A-66 type isolation switch. Background technique [0002] There is a risk of accidents when substation workers operate the GW5A-66 isolating switch. The reason is that the GW5A-66 isolating switch has the risk of sudden fracture of the porcelain pillar, and the broken porcelain pillar 9 (see Figure 6 ) naturally slides under the action of gravity, and the live wire swings naturally, which is easy to touch the staff below it. The staff run in a panic and cause step voltage induction casualties, or directly touch the 66 kV live wire, causing electric shock casualties , At the same time cause power grid (system grounding, discharge, etc.) accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
