By-pass method of combined guide line of electric transmission line

Abstract

The invention relates to a by-pass method of a combined guide line of an electric transmission line. The method comprises the following steps that (1) connecting plates are pressed on the two ends of the by-pass jumper of a number one line and the two ends of the by-pass jumper of a number two line respectively; (2) the two by-pass jumpers are arranged in parallel and the two sides of the two by-pass jumpers are maintained to be even, spacer bars are mounted on the center parts of the two by-pass jumpers, after the spacer bars are firmly mounted, the spacer bars are mounted on the root parts of the connecting plates on the two sides of the two by-pass jumpers respectively, and then spacer bars are mounted among the connecting plates and the centers of the by-pass jumpers respectively; (3) the by-pass jumper of the number one line is connected with corner-shaped connecting plates through the connecting plates; (4) tower mounting is carried out after the by-pass jumpers of the combined guide line assembling is finished; (5) the by-pass jumper of the number one line is in butt joint with the number one line through the corner-shaped connecting plates. According to the by-pass method of the combined guide line of the electric transmission line, due to the fact that the two by-pass jumpers are placed in parallel and the two sides of the two by-pass jumpers are maintained to be even, the spacer bars are mounted on the center parts of the by-pass jumpers, the two by-pass jumpers are made to pass through a thick screw, the thick screw is equivalently an axis support, mutual complementation of twisting force and mutual absorption are obtained by the two by-pass jumpers , and therefore the two by-pass jumpers can be parallel on a same line without a crooked phenomenon.

Description

technical field [0001] The invention relates to a drainage method for multiple conductors of a power transmission line. Background technique [0002] In the prior art, the multiple wires are composed of upper and lower wires and are called #1 wire and #2 wire respectively. The drainage connected by each multiple wire is called #1 wire drainage and #2 wire drainage respectively. The distance is controlled by drainage spacers. However, this method has the following problems: ①Due to the different installation positions, angles and downward sags of the double wire drainage, the length of the two drainages is uneven, and the appearance is abnormal. ② Simultaneously, since the space between the existing double wire drainage spacers is 200mm wide, two thin screws are used to control the respective drainage. Due to the different pressure generated by the tightness of the screws, the twisting force released by the two drains is different, causing the two drains to arch out in acco...
