Description

insulation umbrella

technical field

The utility model relates to the technical field of high-voltage transmission line maintenance in the electric power industry, and belongs to a protective tool for high-voltage transmission line live work, specifically an insulating protective umbrella.

Background technique

For 220kV parallel transmission lines on the same tower, the length of the cross arm located on the upper layer of the tower is less than or equal to the length of the middle phase cross arm. When carrying out middle-phase live work, the ground potential staff on the middle-phase crossarm will be threatened by the upper-phase live wire. If the staff is slightly negligent, such as straightening the waist, stretching, reaching out, etc., there will be no sufficient safety distance between the human body and the upper-phase conductor. It even threatens the safety of workers and power grids. At present, because there is no special insulation protection tool for protection, it is usually used to set up a special person on the tower to monitor and constantly remind the staff for protection. It requires the cooperation of multiple people during work, and the risk factor is high, there are potential safety hazards, and the construction efficiency is low. .
