Problems solved by technology

However, compared with 220kV substation equipment, UHV substation equipment not only has a large difference in structural specifications, but also requires very high electrical performance, especially the post insulator is more than ten meters above the ground, making live maintenance extremely difficult. Therefore, it is necessary to provide a special Insulated lifting platform for live work in high-voltage substations to overhaul related equipment in UHV substations

Embodiment Construction

[0042] An insulated lifting platform for live work in a UHV substation, including a lifting basket, a pole frame, an aluminum alloy ladder, a lifting frame, a working platform, a winch for the lift, a base, a diagonal brace, a winch for lifting the hanging basket, and a wind rope; Two aluminum alloy ladders are arranged on the base of the insulating lifting platform. One side of the aluminum alloy ladder is vertical and the other side is inclined. A support rod is provided between the vertical surface and the inclined surface; The vertical surfaces are connected to each other by frame beams to form the frame of the insulating lifting platform. The door side of the lifting basket has frame beams on the upper part, and the lower part has no frame beams for the access of the lifting frame. Frame beam; lifting frame is provided in the middle of the frame of the lifting platform, and two adjacent lifting frames are connected through a connecting kit, and a lifting frame fixing kit i...

Abstract

The invention provides an insulation lifting platform. The insulation lifting platform comprises a base 7, a stand rod frame 2, a lifting frame 4 and an operation table 5 coaxially arranged in sequence from bottom to top, and is characterized in that a lifting basket 1 is arranged in the lifting frame 4. The insulation lifting platform is excellent in electric insulation performance, can satisfy the requirements of 1000 kilovolt electrified operation, is light in weight, is firm, satisfy safe operation demands, and is convenient to operate, use and transport.

Description

technical field [0001] The invention relates to equipment for electric power maintenance, in particular to an insulating lifting platform for live work in an ultra-high voltage substation. Background technique [0002] Faults of primary equipment such as isolation switches, circuit breakers, transformers, busbars, and bushings involved in UHV substations, as well as pollution flashover accidents caused by pollution of insulators in the substation, all directly affect the safe and stable operation of the power system, and must be carried out in a timely manner. overhaul. However, in the prior art, there are few reports on the scientific research and practice of live work in substations. What is disclosed is live replacement of 110-220kV isolation switch, live treatment of heat generation of isolation switch line clamp equipment, and live replacement of busbar insulators. However, compared with 220kV substation equipment, UHV substation equipment not only has a large differen...
