Rapid Direct-current deicing short circuit device of electric transmission line

Abstract

The invention relates to a rapid direct-current deicing short circuit device of an electric transmission line and belongs to the technical field of electric power line device fittings. According to the structure, the rapid direct-current deicing short circuit device of the electric transmission line comprises a short circuit cable (1). The two ends of the short circuit cable (1) are respectively connected with one line hanging connection clamp. One end of an upper clamping block (2) of each line hanging connection clamp and one end of a lower clamping block (3) of the line hanging connection clamp are movably connected through a hinge, the other end of each upper clamping block (2) is provided with an upper semi-tile combined beryllium copper sleeve (5), and the other end of each lower clamping block (3) is provided with a lower semi-tile combined beryllium copper sleeve (6), wherein the upper semi-tile combined beryllium copper sleeve (5) and the lower semi-tile combined beryllium copper sleeve (6) are matched with the overhead line in diameter. The two ends of the short circuit cable (1) are respectively connected with a downward-convex conductive block (7) in a rapid screwing mode through an internal-thread clamping connector (8). The lower end of each pull rod (4) is square and is connected with the middle of one lower clamping block (3) through a shotpin mechanism. According to the rapid direct-current deicing short circuit device of the electric transmission line, the line hanging connection clamps are connected to two overhead lines which are erected in parallel, a large current power source is loaded between adjacent phases of the overhead lines, heat generated through a resistor of the overhead aluminum conductors is utilized, so that attached ice is rapidly deiced and eliminated, and adjacent phase connection can be rapidly and conveniently conducted. The rapid direct-current deicing short circuit device of the electric transmission line has the advantages of being capable of saving labor, short in time, rapid in installation, convenient to install, and firm.

Description

technical field [0001] The invention relates to the technical field of high-voltage transmission line deicing, in particular to a fast short-circuit device for direct current melting ice of a transmission line, which belongs to the technical field of power line equipment and fittings. Background technique [0002] The weather is cold in winter, and the transmission line is easy to wrap a thick layer of ice. The ice layer increases the weight of the overhead line, and it is easy to generate resonance under the action of the wind, which has a very serious impact on the power tower, thereby affecting the entire power supply system. Threats to our lives and our economy. [0003] The current method of melting ice is mostly DC short-circuit ice melting, which requires the staff to lift the short-circuit cable for high-altitude installation. When performing short-circuit, it is necessary to install and disassemble the connection of multi-strand short-circuit cables and overhead lin...
