Abstract

The invention discloses an aluminum tube wire jumper device used on a double-loop transposition tower, and solves the problems of an existing wire jumper device that an end part is liable to discharge and the capability for overcoming the wind swinging is poor. The aluminum tube wire jumper device is characterized in that a hanging interval rod U-shaped plate (5) is connected with an aluminum tube upper hoop (6) and an aluminum tube lower hoop (7); a fixing bolt (9) successively penetrates through the hanging interval rod U-shaped plate (5), the aluminum tube upper hoop (6), the aluminum tube lower hoop (7) and a lower pad (8) to buckle the aluminum tube upper hoop (6) with the aluminum tube lower hoop (7); an aluminum tube (10) penetrates through a hole formed by the aluminum tube upper hoop (6) and the aluminum tube lower hoop (7); and wire jumper connection seats (11) are fixedly arranged on two ends of the aluminum tube (10), the wire jumper connection seats (11) are provided with grading ring support seats (12), and grading rings (13) are arranged on the grading ring support seats (12). According to the invention, the requirement of electric intervals is met, the machining is simple, and the installation is convenient.

Description

technical field [0001] The invention relates to an aluminum tube type jumper device used on a transposition tower when a 500 kV double-circuit transmission line is transposed. Background technique [0002] In the 500 kV double-circuit transmission line, the transmission tower is divided into two types: the straight tower and the tension tower, and the tower used to realize the transposition belongs to the tension tower. According to the design specification of transmission lines, "in the power network where the neutral point is directly grounded, the transmission lines with a length of more than 100 kilometers should be transposed." . With the improvement of the voltage level and the increase of the number of wire splits, the jumper device on the tension tower is becoming larger and more complicated, and the jumper device has become an important device on the multi-split wire transmission line. The function of the jumper device is to keep a sufficient gap distance between ...
