Problems solved by technology

However, the safety risk of equipotential operation is relatively large. For this reason, the "Safety Regulations" has very strict requirements on personnel combination clearance and operation clearance, and many small-space tower types (mainly 110kV and below tower types) often cannot meet the operation requirements.
As a result, the replacement operation cannot be completed in time

Abstract

The invention discloses a method for replacing a vibration damper. In the operation method, a bracket and a vibration damper claw hook for replacing the vibration damper are adopted for supporting, so that labor force is reduced, and the labor intensity of operators is reduced; and meanwhile, a bolt is locked and detached by using an electric bolt locking device, so that safety and reliability are achieved, and the function of remote operation can be realized.

Description

technical field [0001] The invention relates to an anti-vibration hammer replacement, in particular to a method for replacing the anti-vibration hammer. Background technique [0002] As a necessary fitting for overhead lines, anti-vibration hammers are widely used in all line sections. Its damage, displacement and other problems are one of the common problems of the line. For the damage or displacement of the anti-vibration hammer, if you apply for power outage maintenance, it will reduce the stability of the power grid and affect the power supply. However, if you wait for the power outage opportunity Further replacement will inevitably increase the potential safety hazards of the line and reduce the health level of the line. Therefore, the best solution to this kind of problem is to use the electrified method to eliminate defects in time to ensure the safety and stability of the line. [0003] The main process of replacing the anti-vibration hammer requires delicate work, ...
