Embodiment Construction

[0017] The present invention summarizes the regional characteristics and the characteristics of the support frame. While satisfying the safety of the transmission line, a set of wire support devices made of pillar-type insulating columns, insulating composite triangular profiles and metal flanges is developed to move the large-sag wire from the dangerous distance to the ground. Increase the distance to a safe distance from the ground. The device has a combination function, can be installed and assembled according to the topography, and is suitable for the support of various tower-shaped wires. The support device is mainly composed of composite triangular profiles, lattice frame connected by flanges, and pillar-type composite insulating columns. The whole device is supported by ground foundation supports. The two or four corners are cable-stayed and balanced, and can be permanently assembled. Therefore, the device has the characteristics of high strength, light weight, no terra...

Abstract

The invention belongs to the field of power transmission lines, and relates to an insulating support for conductors of overhead power transmission lines with large drop terrain, including an insulating support, a pillar-type insulating column and a plurality of cable-stayed devices; the insulating support is fixedly installed on a slope; the pillar-type The bottom of the insulating column is fixedly connected to the top of the insulating support, and the top of the pillar-type insulating column is hung with a wire to be supported; one end of the cable-staying device is fixedly connected to the top of the insulating support, and the other end of the cable-staying device is fixedly installed on the slope surface superior. The invention solves the technical problem that the existing large-drop terrain overhead transmission line has potential safety hazards and is prone to equipment failure. The invention provides a reliable and convenient working space for the maintenance personnel by means of the insulation bracket of the conductor of the overhead transmission line, and solves the difficulty of maintenance due to terrain restrictions.

Description

technical field [0001] The invention belongs to the field of power transmission lines, and relates to an insulating support for conductors of overhead power transmission lines with large drop terrain. Background technique [0002] my country's topography is complex and diverse. Among all kinds of terrain, mountains account for the largest proportion, with 33% of mountains, 26% of plateaus, 19% of basins, 12% of plains, and 10% of hills. The terrain in the southwestern region is more complicated. Generally speaking, the northwest is the Hengduan Mountains with high mountains and deep valleys, and the east and south are the Yunnan-Guizhou Plateau. In the whole of Yunnan, more than 94% of the area is mountainous. In daily line inspection work, it is often found that the lowest point of sag of the conductor of the tower with a large height difference is lower than the safe distance, which has caused great hidden dangers to the safe operation of the transmission line. Once an el...
