Abstract
The utility model discloses a split type strain tower of an ultra-high-voltage transmission line with vertically arranged jumper strings, wherein a conductive wire is still suspended onto a tower body without adopting any wire cross arm as well as any jumper cross arm bracket completely. According to the technical scheme of the utility model, jumper strings at the two electrodes of the transmission line are vertically arranged and suspended through two split type iron towers, so that the weight of each iron tower is greatly lightened. Meanwhile, the torques of the longitudinal loads of both the conductive wire and the ground wire on the tower bodies are also greatly reduced and the torsion resistance of the iron towers is obviously improved. The power performance of the iron towers is excellent. Compared with a conventional duplex-F-shaped iron tower and a conventional split type strain tower with horizontally arranged jumper strings, a v-shaped string is suspended by means of the tower body of the iron tower, so that the iron tower is completely free of cross arms. The weight of the tower body is greatly smaller than the weight of the duplex-F-shaped strain tower and the weight of the split type strain tower with horizontally arranged jumper strings. Meanwhile, the split type strain tower with vertically arranged jumper strings is also the lowest in economic indexes.
Description
Technical field
The utility model is a kind of Novel rod tower formula, specifically ± and the split type strain tower of 800kV direct-current ultra high voltage transmission line.
Background technology
For ± single time direct-current ultra high voltage strain tower of 800kV, domestic what mostly select is to do the font tower, and the part location is adopted and jumped the horizontal split type strain tower of string.
As shown in Figure 1, do the font strain tower because simple in structure, stressed clear, the busy line corridor is also narrow, and construction and installation and maintenance are also more convenient, at home and abroad uses in a large number in the electric pressure line projects at different levels, accumulated abundant operating experience, but the more split type strain insulator tower weight of tower weight.
As shown in Figure 2, jumping the horizontal split type strain tower of string is that wire is hung on body of the tower, cancellation wire cross-arm, only establish a utmost point wire jumper cross-arm, another utmost point wire jumper utilizes two split steel towers to hang, and leads, the ground wire longitudinal load greatly reduces the moment of torsion of body of the tower, significantly improved the torsional property of steel tower, power performance is good, and its anti-ice, wind resistance and anti-seismic performance obviously are better than doing the font strain tower.Jump string horizontally but exist, cause the long problem of right tower wire jumper cross-arm.
Summary of the invention
The purpose of this utility model provide a kind of have namely save tower weight, solve preferably the new technology of the longer problem of common split type strain tower wire jumper cross-arm again.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises two split steel towers, and jumper string directly is suspended on two split steel towers.
Described jumper string directly is vertical arrangement and is suspended on two split steel towers.
Split type strain tower of the present utility model will be hung on body of the tower by wire, cancellation wire cross-arm, fully phase out simultaneously wire jumper cross-arm support, the two poles of the earth are jumped string and are all hung by two split steel tower vertical arrangements, greatly alleviated steel tower weight, lead, the ground wire longitudinal load greatly reduces the moment of torsion of body of the tower, significantly improved the torsional property of steel tower, power performance is good.
Compare with the split type strain tower that the dried font steel tower of routine is horizontal with jumping string, this Novel iron tower utilizes body of the tower to hang wire jumper V-type string, has fully phased out cross-arm, and the more dried font strain tower of its tower weight significantly alleviates, obviously reduce than jumping the horizontal split type strain tower of string, economic index is minimum.
Description of drawings
Fig. 1 is traditional dried font strain tower.
Fig. 2 is traditional horizontal split type strain tower of jumping string.
Fig. 3 is the split type strain tower that the utility model is jumped the string vertical arrangement.
Embodiment
As shown in Figure 3, the utility model comprises two ± 800kV split steel tower 1, and jumper string 2 directly is suspended on two split steel towers 1.Need to prove that above-mentioned jumper string 2 is the two poles of the earth jumper string, is technology well known to those skilled in the art, and jumper string 2 directly is vertical arrangement and is suspended on two split steel towers 1 and is preferred forms.
The utility model directly hangs on body of the tower with jumper string, cancellation wire cross-arm, and fully phase out wire jumper cross-arm support, greatly alleviated steel tower weight, lead, the ground wire longitudinal load greatly reduces the moment of torsion of body of the tower, significantly improved the torsional property of steel tower, power performance is good.
