Problems solved by technology

It is conceivable that installing an integral suspension bridge with a span of 10 meters at high altitude is extremely cumbersome and difficult to realize; even if it is barely realized, safety and practicality cannot be guaranteed at all, and the cost is too high
[0006] Therefore, there is a lack of an outlet device at this stage, which can help the staff complete the outlet process without damaging the composite insulator string.

Abstract

The embodiment of the invention provides a groove-type line outgoing device. The groove-type line outgoing device comprises a groove-type pedal, wherein semicircle hooks are arranged at two sides of the groove-type pedal. According to the groove-type line outgoing device provided by the invention, the groove-type line outgoing device is suspended on a composite insulator chain by the semicircle hooks, the line outgoing process can be finished through the passage of the groove-type pedal by a worker, and the stepping and the climbing on the composite insulator chain can be avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission line design, and in particular relates to a grooved outlet device. Background technique [0002] In recent years, with the increasing demand for electricity and the development of transmission technology, UHV transmission lines such as 800kV and 1000kV have begun to be constructed and put into operation in China. In areas with heavy pollution levels, the use of composite insulators can play a positive role in improving the pollution flashover resistance of transmission lines and preventing and curbing the occurrence of pollution flashover accidents, and composite insulators have the advantages of low cost and maintenance-free. The popularization and application in China will bring remarkable benefits. [0003] However, conventional strain insulator strings generally use glass insulators (or porcelain insulators). When workers need to carry out outgoing operations, they can directly ste...
