Lifting installation tool of high pressure bushings and high pressure leads

Abstract

The invention relates to a lifting installation tool of high pressure bushings and high pressure leads, comprising a lifting hook and a lifting rope. A high pressure lead device is arranged at the middle part of the lifting hook. The high pressure lead device is formed by connecting an anchor ear which can rotate on the lifting hook with a circular ring by a connecting piece. The anchor ear comprises an inner ring piece, an outer ring piece and balls arranged at the middle part. One end of the lifting rope is provided with a bolt with an outer thread, and the outer thread can be matched and connected with a hollow cropper rod with an inner thread at the end part of the high pressure lead fixed on a base seat of the high pressure bushing. The lifting rope is one of steel wire rope, hemp ropes, line ropes or nylon ropes. The invention has the advantage of providing the lifting installation tool of the high pressure bushings and the high pressure leads, and by adopting the tool, the highpressure leads fixed on the base seat of the high pressure bushings can be smoothly, safely, reliably and nondestructively led out from the high pressure bushings when the high pressure bushings are installed.

Description

technical field [0001] The invention relates to the field of high-voltage power systems, in particular to a lifting installation tool for high-voltage bushings and high-voltage leads. Background technique [0002] The high-voltage bushings installed on large-scale transformers, reactors and other electrical appliances are very heavy, and it is difficult to install them by hand. Generally, crane hooks, hoist hooks and other equipment are used to lift and install them. During installation, a steel wire rope is generally used to connect the high-voltage bushing and the hook. However, when installing the high-voltage bushing, a high-voltage lead wire needs to be drawn from the middle of the high-voltage bushing. One end of the high-voltage lead wire is connected to the high-voltage bushing base of a transformer or reactor, and the other end is connected to a high-voltage cable or other electrical equipment. . When lifting and installing the high-voltage bushing, the steel wire...

AI Technical Summary

Problems solved by technology

When hoisting and installing high-voltage bushings, the steel wire rope and high-voltage lead wires are often entangled together due to the rotation of the hook, which brings a lot of hemp to the installation of high-voltage bushings, and even damages the high-voltage lead wires in severe cases.
