Connecting device for electric high tension lines

Abstract

The invention discloses a connecting device for electric high tension lines. The connecting device comprises three groups of jointing bodies with the same structure, namely a first jointing body, a second jointing body and a third jointing body; each jointing body consists of an upper clamping surface (1), a lower clamping surface (5) and a line long tube (2); two sides of the upper clamping surface (1) and the lower clamping surface (5) are assembled through a fastening device (3); the section of the surface and the section of an inner cavity of the line long tube (2) are approximately equilateral triangles; the line long tube (2) is uniform in wall thickness and is made of flexible materials; a clamping space (4) is formed inside the line long tube (2); the fastening device (3) consists of a bolt and a nut; the first jointing body and the second jointing body are assembled through a first connecting rod (6); the second jointing body and the third jointing body are assembled through a second connecting rod (7).

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a connection device and a connection method of a high-voltage transmission line. Background technique [0002] In recent years, due to the influence of macro-climate and micro-meteorological conditions in my country, ice disaster accidents have occurred frequently, causing huge economic losses. Under certain meteorological conditions, ice crystals accumulate around the wires on the power transmission line. Icing will increase the load on the wires and towers. At the same time, the shape of the circular cross-section of the wires will be changed, and the windward area will be enlarged. Events such as network, torsion, wire disconnection, and pole down, resulting in large-scale power outages. In 2008, a large-scale continuous low temperature, rain, snow and freezing weather hit central, southern and southern China, causing accidents such as the collapse of elec...

AI Technical Summary

Problems solved by technology

Under certain meteorological conditions on the transmission line, ice crystals accumulate around the wires. Ice coating will increase the load on the wires and towers, and at the same time change the circular cross-sectional shape of the wires and expand the windward area. network, twisting, disconnection, pole down and other events, resulting in large-scale power outages

In 2008, a large-scale continuous low temperature, rain, snow and freezing weather hit central, southern and southern China, causing accidents such as pole collapse and power interruption, which seriously affected the safe and stable operation of the power communication network

The existing technology generally considers the material of the high-voltage line and the load of the tower, but how to increase the disaster resistance ability from the new setting method of the high-voltage line and the connection device between the lines has not been disclosed
