Method for installing or removing high voltage bushing by using C-shaped hoseclamp cross binding strap

Abstract

The invention relates to a method for installing or removing a high voltage bushing by using a C-shaped hoseclamp cross binding strap, wherein the C-shaped hoseclamp cross binding strap comprises two main straps (1) having the same length, an annular auxiliary strap (2) and a hoseclamp strap (3) capable of being bent into a C shape, both ends of the two main straps (1) are respectively provided with a tool U-shaped ring (4) and a hanging ring (5), and a closed ring belt is folded and twisted and then is bent to form the hoseclamp strap (3). According to the present invention, with the use of the C-shaped hoseclamp cross binding strap to install or remove the high voltage bushing, it can be ensured that the main straps and the hoseclamp strap can closely attached to the high voltage bushing without displacement production, the repeated adjusting during the lifting process is not required, and the work is efficient and safe.

Description

technical field [0001] The invention relates to the technical field of installing or removing a high-voltage bushing by using a sling on a power construction site. Background technique [0002] The high-voltage bushing is a special equipment of the power system. It is divided into the exposed atmospheric side of the bushing and the internal side of the bushing equipment by the high-voltage bushing flange. The installation or removal of the high-voltage bushing must be kept vertical during the hoisting process, so that the center line of the nylon sling that binds and lifts the high-voltage bushing is infinitely close to the center line of the bushing after being stressed, otherwise the equipment body may be damaged. [0003] Nylon sling is a spreader used to install or remove high-voltage bushings, and it is widely used in electric power construction work production sites. When installing or removing high-voltage bushings such as converter transformers, AC transformers, HGI...

AI Technical Summary

Problems solved by technology

Using the above method, since the tail rope of the waist hoop sling is fastened by manpower, after each sling is stressed, there are the following problems: (1) The knots of the waist hoop sling are in danger of falling apart

Using the above method, although the waist hoop sling is tied up after the main sling is stressed, and the tail rope knot of the waist hoop sling is fastened by manpower, the following problems still exist as in the installation: (1) Waist hoop sling Knots may still unravel

(2) After the high-voltage bushing is separated from the equipment body, once the center line of the main sling deviates from the center line of the high-voltage bushing, the waist hoop sling positioned around the main sling will increase, and the center of the bushing will tilt to a certain side, which is not only possible It will damage the equipment, and even cause a difficult situation, which will inevitably lead to low work efficiency
