Stringing method of high-tension overhead line

Abstract

The invention provides a stringing method of a high-tension overhead line, which comprises the following steps of: installing a cross arm with adjustable horizontal direction on a wire pole, arranging one set of main line connection insulator strings on one side of the cross arm in the horizontal direction, and arranging one set of branch line connection insulator strings on the other side of thecross arm in the horizontal direction; adjusting the horizontal direction of the cross arm, and arranging the cross arm between the direction of the main line and the direction of the branch line; and connecting a main line with the main line connection insulator strings, connecting a branch line with the branch line connection insulator strings, and connecting the main line with the branch line.The stringing method of a high-tension overhead line breaks through the traditional stringing mode, and has the advantages of ingenious design, simple stringing structure, strong practicality, material saving, convenient construction, increased distance from a conductor to the ground with the same pole height, and convenient later operation management.

Description

technical field [0001] The invention relates to a stringing technology of a high-voltage line, in particular to a stringing method of a high-voltage overhead line. Background technique [0002] At present, most of the high-voltage overhead lines are wired according to the old standard and adopt the traditional wiring method: such as figure 1 and figure 2 As shown, the main line 5 is connected to the insulator string 22 on the main line cross arm 11, and the main line 5 is perpendicular to the main line cross arm 11, and then the branch line 6 is connected to the insulator string on the branch line cross arm 12. 32 connection, and make branch line 6 and branch line cross arm 12 perpendicular, finally, main line 5 and branch line 6 are connected through lead; Wherein, main line cross arm 11 and branch line cross arm 12 are not in a horizontal plane; At the same time, a pull wire 82 and a pull wire 81 are also drawn on the wire rod 4 , and the pull wire 82 and the pull wire ...

AI Technical Summary

Problems solved by technology

[0003] During the long-term practice, the following problems have been found in the traditional wiring method: cumbersome process and troublesome construction; heavy workload, low efficiency, and waste of manpower and material resources; irregular and complicated line connections, which is not conducive to safety; a large number of crossarms are used , a waste of wiring auxiliary materials; staggered cross-arms make the distance between the wires of the same pole height and the ground low; the number of wire poles is too large, which is not conducive to construction and increases costs
