Operating tool and operation method for electrically replacing T-type mounting point suspending insulator in 110kV line steel pipe rod

Abstract

The invention relates to a device for electrically replacing an insulator in a high-voltage line, and in particular relates to an operating tool and an operating method for electrically replacing a T-type mounting point suspending insulator in a 110kV line steel pipe rod, which can be applied to a cross arm T-type mounting point or similar T-type mounting point power tower of a 100kV-220kV transmission line steel pipe rod. The operating tool is mainly a nested clamping tool, which is simple in structure, light in weight and less in component and is easy to operate. The operating method based on the operating tool is a load-carrying method which is used to electrically replace T-type mounting point suspending insulators. The operating method is simple and easy to implement, the operating space required by the operating method is small, many high-altitude operators are not required, and the safety gap requirement is low. According to the invention, the problem that a larger operating space and a safety gap can not be provided on the power tower of the steel pipe rod is solved, the operation for electrically replacing the cross arm T-type mounting point insulator in the 110kV line steel pipe rod is realized, a series of economic, production and power supply problems caused by blackout can be avoided, and the gap that the insulators of the power tower of the steel pipe rod are electrically overhauled is filled. The operating tool and the operating method thereof have significant meanings.

Description

Technical field [0001] The invention relates to a live replacement device for an insulator on a high-voltage line, in particular to a working tool and a working method for the live replacement of a T-shaped suspension insulator on a 110 kV line steel pipe pole. It can be suitable for 110 kV~220 kV transmission line steel pipe pole cross arm T-shaped hanging point or similar T-shaped hanging point type power pole tower. Background technique [0002] In recent years, in the construction of urban power grids, a large number of high-voltage power poles have been constructed using steel pipe poles as materials. This is because steel pipe poles occupies a small space, low investment, fast construction speed, and beautiful and practical. However, the surface of this type of tower steel pipe is smooth, the cross arm is short and narrow, resulting in a narrow operating space, and the steel pipe cross arm structure and insulator string hanging point types are diverse, generally double or m...

AI Technical Summary

Problems solved by technology

However, the surface of this type of steel pipe pole is smooth, the cross arm is short and narrow, resulting in a narrow operating space, and the steel pipe pole cross arm structure and insulator string hanging point types are various, generally double or more than four rounds are erected on the same tower, and the safety clearance It is also small; in contrast, the traditional working tools and methods for live replacement of insulators require the cooperation of multiple people, and require sufficient operating space and safety clearance, the tools are scattered, and the operation process is relatively cumbersome. None of the safety gaps can meet the requirements of traditional operations, and the operation is extremely difficult. Therefore, there are no operating tools and methods for live replacement of 110 kV line steel pipe pole insulators

As the reliability of power supply becomes higher and higher, if you still rely on power grid outage operations, you will not be able to adapt to the requirements of the power grid development situation
