Description

A foldable light-duty single string tension insulator string device

technical field

The utility model belongs to the technical field of electric power auxiliary equipment, in particular to a foldable light-duty single-string tension insulator string device.

Background technique

Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line. When producing a single string of tension insulators, the operator can only ride on the insulator. Due to the increase of unbalanced force, the insulator string will tilt and rotate, so the operator will often drop the insulator string, which greatly increases the risk of work. Moreover, this operation method is relatively difficult, so many people cannot produce a single string of tension insulator strings. Although some people currently use the method of climbing rope ladders to produce a single string of tension insulator strings, this method is not only labor-intensive, but also needs to carry a large number of heavy tools. Some places that vehicles cannot reach, the staff only have manual handling. Difficulty and intensity are greater, and time-consuming. Therefore, there is an urgent need to research and develop a device that is easy to carry and easy to operate.
