Description
Technical field
The utility model relates to a kind of overhead transmission line iron tower, in particular, relate to the same tower three back transmission line tangent towers of a kind of shape such as wine cup shape.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, and superhigh pressure, big capacity, multiloop are carried the inexorable trend that has become the electric power conveying, but ultra-high-tension power transmission line causes various contradictions more and more outstanding owing to taking too much, the wide problem in corridor.High pressure and extra high voltage network adopt the situation of multi-circuits transmission lines on single tower to be obvious ascendant trend in recent years.
Existing superhigh pressure with tower multiloop transmission line mainly based on the double loop, growing tension along with circuit corridor resource, also begin to apply to engineering design with tower four loops, their common feature is that feeder number is even number, left and right symmetrically is distributed in the body of the tower both sides, has greatly reduced the circuit corridor.
At the situation of 3 times supertension lines under needing to arrange in same corridor, the general practice is the scheme that adopts a common-tower double-return Lu Jiayi single loop parallel at present, needs to take very wide circuit corridor for this reason.If a common-tower double-return road and a single loop are made up on same iron tower, form one with tower three loops, will solve transmission line effectively and take too much, the wide problem in corridor.The utility model will be to studying with tower three loops series iron tower, and develop a kind of with tower three back transmission line tangent suspension towers.
