Description

Auxiliary operation platform for overhauling inlet and outlet wires of 110kV strain double-string composite insulator

Technical Field

The utility model relates to a power transmission line overhauls technical field, especially relates to a be used for two cluster composite insulator business turn over wires of 110kV strain insulator to overhaul auxiliary operation platform.

Background

The high-voltage transmission line needs to be maintained frequently in a power failure mode, and during power failure maintenance, a lead needs to be led out to perform operations of adjusting the damper, repairing the lead, installing a backup wire clamp, removing a drainage wire and the like. The composite insulator has good mechanical property and stain resistance, and is widely applied to transmission lines in China. However, due to the characteristics of the composite insulator, the composite insulator bears small radial (perpendicular to the central line) stress, so that the high-voltage insulator used for the tension rod is prevented from being trodden or subjected to any type of radial load, otherwise, the high-voltage insulator is broken, and the umbrella part is made of silicon rubber, so that the umbrella part is relatively soft in texture and is easily damaged to damage the sealing property, and the insulation performance is reduced. At present, when the tension double-string composite insulator is subjected to wire outgoing maintenance operation, most workers still adopt the operation mode of the original porcelain insulator and glass insulator string, namely directly ride on the tension composite insulator to move forward to perform wire outgoing operation, the umbrella skirt of the composite insulator string is easily damaged by the operation mode, a composite insulator mandrel is easily damaged, even the mandrel is broken, and huge potential safety hazards are brought to personal safety of field workers and safe and reliable operation of a power grid. Along with the progress of China's power grid construction as well as fierce in recent years, the transmission line channel is increasingly tense, so that a large number of circuits of the same tower and double circuits or even the same tower and multiple circuits are put into use, induction voltage is easy to appear on a power failure maintenance circuit, and great potential safety hazard is brought to the working personnel to work on a lead on a tension tower.

Because the composite insulator full skirt is the silicon rubber material, the easy emergence is damaged, for the emergence that prevents the transmission line accident, at the maintenance in-process, should avoid damaging composite insulator's full skirt, sheath and tip seal, forbid the staff strictly and step on composite insulator, and then avoid because of trampling the damaged or plug of silicon rubber full skirt that causes breaks away from, brings the hidden danger for the safe operation of circuit. Thus, for composite insulators, personnel are not allowed to enter and exit along the composite insulator.

At present, single-hanging-point double-string composite insulators are adopted in power transmission line strain towers governed by companies, and due to the fact that gaps of the insulators are too large, operating personnel cannot keep balance and cannot normally exert force in the operating process, and therefore the high-altitude falling risk exists in the operating processes of cleaning the insulators, repairing split pins and the like.

With the operation of a large number of lines erected by double-loop or even multi-loop same towers and the development of power grid construction, a power transmission channel is short, so that adjacent, parallel and crossed spanning lines are increased day by day, and induced electricity hurting accidents are easy to happen in power failure maintenance lines.
