Problems solved by technology

If a single circuit is introduced, it is easier to implement; if a double circuit is introduced, that is, double T connection, the arrangement is more complicated due to the fact that the wires cross more in the air; if the cable is used, the distance between the lines is better controlled, but the cost is high. 3 to 4 times the cost; overhead and cable mixed type, there are more fault points

Embodiment Construction

[0010] Such as Figure 1-3 As shown, the double T bar includes a vertical bar 1 and a lightning protection wire support 2, a conductor cross arm 3 on the original line, a conductor cross arm 4 on the double T line, a conductor cross arm 5 in the original line, and a conductor cross arm 6 in the double T line. 1. The lower conductor cross arm 7 of the original line and the lower conductor cross arm 8 of the double-T line are symmetrical from top to bottom on the vertical bar 1 and the lightning protection wire support 2 is installed at intervals. The original line upper conductor cross-arm 3 and the double-T line Conductor crossarm 4, conductor crossarm 5 in the original line, conductor crossarm 6 in the double T line, original line lower conductor crossarm 7 and double T line lower conductor crossarm 8, lightning protection wire support 2, original line upper conductor crossarm 3. The cross-arm 5 of the conductor in the original line, the cross-arm 7 of the lower conductor of ...

Abstract

The invention discloses a high-voltage line dual-T rod. A lightning wire bracket (2), an original line upper lead cross arm (3), a dual-T line upper lead cross arm (4), an original line middle lead cross arm (5), a dual-T line middle lead cross arm (6), an original line lower lead cross arm (7) and a dual-T line lower lead cross arm (8) are symmetrically arranged on a vertical rod (1) from top to bottom at certain intervals; the lightning wire bracket (2), the original line upper lead cross arm (3), the original line middle lead cross arm (5), the original line lower lead cross arm (7), the dual-T line upper lead cross arm (4), the dual-T line middle lead cross arm (6) and the dual-T line lower lead cross arm (8) are distributed in a cross way. By adopting the high-voltage line dual-T rod, the original arrangement way of an original line is kept constant, and the vertical distances among lines are doubled; lines in the same loop are connected over the air, and lines in different loops are crossed over the air, so that the line arrangement is compact, and the inter-line safety and line grounding safety are ensured.

Description

technical field [0001] The invention relates to a double T bar of a high-voltage line, which is used in the construction of high-voltage power transmission and transformation projects. Background technique [0002] In the construction of power transmission and transformation projects, sometimes due to the lack of power supply points or the tight channels, the power points of new power transmission and transformation projects must be introduced from the double Ts of the built high-voltage lines. If a single circuit is introduced, it is easier to implement; if a double circuit is introduced, that is, double T connection, the arrangement is more complicated due to the fact that the wires cross in the air; if the cable is used, the distance between the lines is better controlled, but the cost is high, and it is overhead. The cost is 3 to 4 times; overhead and cable mixed type, there are more fault points. Contents of the invention [0003] The purpose of the present invention...
