Tower minimum space operating method based on insulated isolation umbrella

Abstract

The invention provides a tower minimum space operating method based on an insulated isolation umbrella. The movement range of operating personnel is limited through a constraint limiting rod and an isolation layer of the constraint limiting insulated isolation umbrella, the distance between the operating personnel and an electrified body meets the safety requirement all the time when the operating personnel enter the range and reaches the operating position to work, and the method is applicable to various tower operations along a tower cross arm, wherein the various tower operations include detection of zero resistance insulators, replacement of a whole string of linear insulators on a tower, replacement of a whole string of tension insulators on the tower, and replacement of the whole string of tension insulators on the tower in cooperation with equipotential. In the operating process of the method, shutting down is not required, the operating personnel are prevented from entering the electrified space according to limiting prompt of the insulated isolation umbrella and can work at ease, operating efficiency is improved, operation is easy and convenient, and safety of the operating personnel is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of grid pole and tower operation, in particular to a minimum space operation method for pole and tower based on an insulating isolation umbrella. Background technique [0002] In recent years, due to the increasingly tense line corridors, there are more and more multi-circuit lines on the same tower in the new and reconstructed transmission lines, which have exceeded 30% of the existing transmission lines. According to the state-of-the-art maintenance requirements, D and E maintenance items need to be repaired, maintained and replaced without power failure, and according to peer benchmarking and power supply reliability requirements, it is difficult to apply for power outages for multi-circuit lines on the same tower, and once the power of the lines is interrupted, it will cause Large-scale power grid outages seriously affect the power supply reliability and power supply time of the grid, which requires grid...
