Device for live replacement of cross arm and insulator string and application method

Abstract

The invention relates to the technical field of electrical machinery manufacture, specifically to a device for live replacement of a cross arm and an insulator string and an application method. The device is characterized in that the device is provided with an insulating cross rod, left and right sides of the insulating cross rod are symmetrically provided with wire supporting units which support wires on two sides of the cross arm, front and rear sides of a middle part of the insulating cross rod are respectively provided with an enclasping unit used for enclasping a telegraph pole and a wire supporting unit used for lifting a wire at the top of the telegraph pole, the three units are integrated, a cross arm can be replaced, an insulator string on the cross arm can also be replaced, and an insulator string on the top of the telegraph pole can also be replaced. The device for live replacement of the cross arm and the insulator string has the advantages of being reasonable in structure, being convenient to replace, saving manpower, being high in work efficiency, etc.

Description

technical field [0001] The invention relates to the technical field of electrical machinery manufacturing, in particular to a device and a method for replacing cross-arms and insulator strings with live charging, which are reasonable in structure, convenient in replacement, save manpower, and high in work efficiency. Background technique [0002] As we all know, with the continuous development of social economy, the public has higher and higher requirements for reliable power supply. Due to the advantages of small footprint, low investment, fast construction speed, beautiful and practical, etc., steel pipe poles have been used in the construction of urban power grids in recent years. A large number of applications, however, with the continuous increase of power lines, some equipment is gradually aging, and the daily maintenance and repair tasks of power transmission lines are becoming more and more heavy.

[0002] As we all know, with the continuous development of social economy, the public has higher and higher requirements for reliable power supply. Due to the advantages of small footprint, low investment, fast construction speed, beautiful and practical, etc., steel pipe poles have been used in the construction of urban power grids in recent years. A large number of applications, however, with the continuous increase of power lines, some equipment is gradually aging, and the daily maintenance and repair tasks of power transmission lines are becoming more and more heavy. Due to the smooth surface of steel pipe rods and steel pipes in line design, the operating space is narrow, especially when the crossarm is placed on the wire The pole is easy to tilt, resulting in different counterweights on the left and right sides, which makes the work of replacing insulator strings and cross arms more and more difficult, and brings difficulties to the task of live maintenance of equipment. The hoist lifts the wire, and then manually replaces the insulator string and the cross arm. This method requires a large amount of engineering, increases manpower and material resources, and reduces work efficiency. It is impossible to replace the cross arm and insulator string at the same time.
