Embodiment

[0023] figure 1 It shows a power line de-icing jump buffer device, including line clamp 1, first composite insulator 2, nylon rope 3, second composite insulator 4, spring buffer 5 and fixing hardware 6 connected in sequence, and line clamp 1 is fixed On the transmission line 7, a nylon rope 3 is connected to the bottom of the clamp 1, and the nylon rope 3 can be replaced irregularly according to the degree of aging. The nylon rope 3 has a certain elastic deformation, which can buffer the jumping of the transmission line, and meanwhile it has insulation properties. The second composite insulator 4 is connected to the connecting rod 506 of the spring buffer 5 through the steel strand 10. The bottom of the spring buffer 5 is provided with a fixed ring, which is connected with a UT-shaped clamp through the steel strand, and can also be fixed through other fixing hardware 6. fixed. The fixing hardware 6 is provided with a grounding wire or a grounding resistor, and the bottom of ...

Abstract

The invention discloses a power transmission line deicing jump buffer device, and relates to the technical field of power transmission line deicing jump prevention and control. The buffer device comprises a wire clamp, a first composite insulator, a nylon rope, a second composite insulator, a spring buffer and a fixing fitting which are connected in sequence, wherein the wire clamp is fixed on a power transmission line, a grounding body is arranged on the fixing fitting, the end of the fixing fitting is fixed on the ground, the spring buffer comprises a shell, a compression spring, a guide rod, an extension spring and an end cover, the shell is a hollow barrel, the top of the shell is covered with an end cover, one end of the extension spring is connected with the bottom wall in the shell, the other end of the extension spring is connected with the guide rod, the other end of the guide rod is sleeved with the compression spring, the guide rod penetrates through the end cover to be connected with the second composite insulator, and the compression spring abuts against the end cover. Through the design of the compression spring and the extension spring in the spring buffer, the large jump of the power transmission line caused by sudden pressure loss due to ice falling is buffered, the jump amplitude is limited within a safe height, and the short circuit fault between lines is avoided.

Description

technical field [0001] The invention relates to the technical field of prevention and control of deicing and jumping of transmission lines, in particular to a buffer device for deicing and jumping of transmission lines. Background technique [0002] There are four types of icing on the line: rain rime, rime, mixed rime and wet snow. The hazards caused by icing on overhead transmission lines are becoming more and more serious, often causing phenomena such as overload, ice flashing, galloping, ice-off jumping, etc., resulting in accidents such as line tripping, disconnection, tower collapse, and communication interruption. Icing has become a threat to the power grid. important factor for safe operation. At present, the most severe ice and snow disasters on the line are in the north and Tibet, because the weather is cold and dry in winter, which is specifically manifested as rime. At present, there are very complete research and treatment measures for the treatment of rime tr...
