Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a multi-conductor power transmission line that prevents the generation of corona 1.6 sound during rain.

In recent years, in order to prevent the occurrence of corona noise during rain, Ll, Q, and auxiliary wires have been installed approximately below the center of the two conductors on the ground side among the multiple conductors of the multi-conductor power transmission line. has been proposed. In this way, the potential gradient in the direction in which water droplets are formed on the conductor on the ground side, that is, in the vertical direction, which is a particular problem during rain, is reduced, so that the generation of corona can be effectively prevented. In this case, the extension wire needs to be supported on the conductors of the multi-conductor power transmission line, but it is generally considered to be supported on spacers that support these conductors at intervals.

However, doing so would require a large number of multi-conductor spacers, which would increase the load on the entire Kushiro area, making it necessary to increase the strength of the steel tower.

The object of the invention is to provide a multi-conductor transmission line that can support corona prevention wires without increasing the load on the line.

The embodiments of the invention will be described in detail with reference to the drawings.
2 and 2 show a multi-conductor power transmission line 10 according to the present invention, and this multi-conductor power transmission line l has a plurality of conductors, for example four conductors 12.
14, 16, and 18, and a conductive support Hw attached approximately below the center of the hot body 6.18 on the ground side.

The multi-conductor spacer 22, 22' --- is attached to the spacer body having a substantially rectangular shape as shown in Figure 3.

As can be seen from FIGS. 3 and 4, the clamps 30B and 36C that grip the extension wire 20 have semiconducting M on their gripping surfaces.
Preferably, it has a value of 38.40. If this is done, the current will not flow to the extension wire side, so the cross-sectional area can be reduced.

According to the invention, as described above, in order to support the conductor with a fixed slackness of the wire for corona generation prevention, a plurality of multi-body spacers are arranged between them. Since a three-conductor spacer is used to support the conductor, it is possible to significantly reduce the load on the entire line (jf), and therefore, the strength of the steel tower is small and there is an advantage in folding it.
