Self-adaptive insulation isolation device and single-side live-line maintenance method based on self-adaptive insulation isolation device

Abstract

The invention relates to a self-adaptive insulation isolation device and a single-side live-line maintenance method based on the device, and the self-adaptive insulation isolation device comprises an insulation separation plate which is installed on a telescopic support frame and is used for providing an insulation isolation operation area for an operator; the movable chassis is used for bearing the insulating partition plate, the distance measuring equipment, the telescopic supporting frame, the rectangular coordinate moving platform and the main controller. The distance measuring equipment is mounted at the top of the telescopic support frame; the telescopic support frame is mounted on the rectangular coordinate mobile platform and is used for driving and adjusting the position of the insulating partition plate in the vertical direction of the horizontal plane; the rectangular coordinate moving platform is fixed on the movable chassis and is used for driving and adjusting the position of the insulating partition plate in the x-y direction of the horizontal plane; the main controller is connected with the distance measuring device and used for movement of the rectangular coordinate moving platform and the telescopic supporting frame. The device has the advantages of flexible deployment, self-adaptive adjustment of an insulation isolation protection area, single-side hot-line work and the like.

Description

technical field [0001] The invention belongs to the field of maintenance of high-voltage equipment, and more specifically relates to an adaptive insulation isolation device and a single-side live maintenance method of a high-voltage isolation switch based on the device. Background technique [0002] High-voltage isolating switches are important equipment in transmission lines, but they are often affected by harsh environments such as wind, rain, snow, pollution, condensation, ice and thick frost, and are prone to equipment aging or damage. Therefore, timely and convenient maintenance is needed to ensure the normal operation of the power grid system. However, in the conventional maintenance operation mode, both ends of the high-voltage isolating switch need to be kept in a power-off state to ensure the safety of workers in the high-voltage environment. This kind of power-off maintenance operation method seriously affects the normal operation of the power grid, resulting in h...

Problems solved by technology

However, the existing insulation devices are fixed installations with an estimated safety distance. During operation, they cannot adaptively adjust the insulation isolation protection area, nor can they be portable and mobile. They also lack the perception of key external information such as working safety distances, insulation positions, and electrified positions.

[0004] Therefore, the detection method of high-voltage disconnectors based on this device lacks the ability to deal with safety uncertainties, and it is difficult to adapt to the operational requirements of safe maintenance of disconnectors at different voltage levels
