Instation hot-line work combined insulation ladder

Abstract

The invention relates to an instation hot-line work combined insulation ladder which comprises at least two groups of symmetrically arranged herringbone support ladders, wherein the support ladders comprise ladder legs which symmetrically stand on the ground; the ladder legs are internally provided with sliding rails; sliding ladders are connected to the insides of the sliding rails in a sliding manner; sliding ladder heads which are arranged on the tops of the sliding ladders arranged at the two sides of the same support ladders are moveably connected; elastic flat ladders are fixedly connected between the sliding ladder heads at different support ladders; insulation work platforms extending outwards are arranged at the end parts of the flat ladders. According to the invention, the instation hot-line work combined insulation ladder is high in structure connection manner stability, large in bearing capacity and strong in safe reliability; the instation hot-line work combined insulation ladder can be flexibly assembled and used according to the site environment under the condition that the traditional herringbone ladder can not meet safety spacing on site, and can meet different height requirements, so people can reasonably regulate the electric field in and out positions by virtue of the combined ladder, and thus powerful guarantee on the safe and effective hot-line work of instation electrical equipment is improved.

Description

technical field [0001] The present application relates to an insulating ladder, in particular to a combinable and disassembled combined insulating ladder for live work in a station. Background technique [0002] The substation is the hub of the entire power grid and plays an important role in the safe operation and reliable transmission of electric power. Live detection and live maintenance of substation equipment is an important technical means to ensure reliable operation of substations. In the live working method of the equipment in the substation, when the operators rely on the insulating ladder to enter and exit the electric field, the live workers need to overcome many difficulties such as small working space and many peripheral equipment at the working point. Therefore, the on-site operators must strictly control the insulation ladder. The location of the equipment in the area can meet the safety distance requirements for personnel entering and leaving the electric f...

AI Technical Summary

Problems solved by technology

In the live working method of the equipment in the substation, when the operators rely on the insulating ladder to enter and exit the electric field, the live workers need to overcome many difficulties such as small working space and many peripheral equipment at the working point. Therefore, the on-site operators must strictly control the insulation ladder. The location of the equipment in the area can meet the safety distance requirements for personnel entering and leaving the electric field, which increases the difficulty of on-site operations and also limits the feasibility and practicability of the equipment in the station to carry out live work.

[0003] In the prior art, when the electrical equipment of 110 and 220 kV substations are operated at the same potential, ordinary insulating ladders are used for climbing operations, and there are problems such as the combination gap is not easy to meet the requirements of the regulations, the physical exertion of the operators is large, and the safety and reliability are low.
