Abstract
The utility model provides a multi-loop wiring on the same tower compact transmission line iron tower , which comprises a tower, insulator strings and a cross arms. The utility model is characterized in that: the three layers of cross arm in each loop are shorter than each other from top to bottom; the V-shaped structure is applied in the corresponding insulator strings. The structure of the utility model obviously reduces the vertical phase spacing between every loop and the horizontal distance between two loops and arrayed horizontally, which evidently improves the natural transmission power of every loop compared with the general multi-circuit on the same tower and reduces the transmission line corridors. Meanwhile, the project cost for transmission capacity dropped greatly, and the engineering construction investment also decreases.
Description
Technical field
The utility model relates to a kind of iron tower of power transmission line, specifically is a kind of multiloop (twice and more than) wiring on the same tower compact transmission line iron tower.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, high pressure and super-pressure are carried has become the inexorable trend that electric power is carried, but high pressure and extra high voltage network cause various contradictions more and more, increasing owing to taking too much, the wide problem in corridor, and 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.Adopting the compact technology of transmission of electricity can obviously improve the natural power of transmission line of electricity, greatly reduce the transmission line of electricity width of corridor, is national key scientific and technological project.It is to solve high pressure and extra high voltage network to take that the corridor is too much, the key of wide problem that this advanced technology of how compact being transmitted electricity applies on the high pressure of multi-circuits transmission lines on single tower and the extra high voltage network.
General employing is the structure that cross-arm short, middle cross-arm in upper strata is long and lower floor's cross-arm is short in the every loop of existing multiloop iron tower, the gap circle that this structure makes upper strata its lead of cross-arm and the minimum distance point of middle level cross-arm are near the cross-arm middle part, guarantee to carry the safety of electricity, will cause the situation that distance strengthens between cross-arm and the middle cross-arm.
Summary of the invention
The purpose of this utility model just provides a kind of multi-circuits transmission lines on single tower compact transmission line iron tower, when solving the ultra-high-tension power transmission line wiring on the same tower tower body too high, take too much, the wide problem in corridor.
The purpose of this utility model is achieved in that by tower body, insulator string and cross-arm to be formed, and it is characterized in that, the three layers of cross-arm in the every loop of tower body shorten from top to bottom successively, and the corresponding insulation substring adopts V-structure.
The utility model is because tower body adopts the three layers of cross-arm in every loop to shorten successively from top to bottom, and the corresponding insulation substring adopts the V-structure form.So that the vertical phase spacing in every loop can obviously reduce, the tower body overall height reduces, horizontally and the horizontal range between two loops also had obviously and reduced, thereby the natural transmission power in every loop is significantly improved than every loop of conventional multiloop with tower, also there has been obvious compression in the transmission line of electricity corridor, not only make simultaneously the construction costs of convey unit capacity that decline is significantly arranged, and can also save engineering construction investment.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of existing iron tower.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated
As shown in Figure 1, 2, the utility model is made up of tower body 3, insulator string 2 and cross-arm 1, the three layers of cross-arm 1 in tower body 3 every loops shorten from top to bottom successively, corresponding insulation substring 2 adopts V-structures, adopt this form of structure make cross-arm V-type lead that insulator string is hung gap circle and middle cross-arm minimum range and in the minimum range of the round and following cross-arm in the gap of cross-arm V-type lead that insulator string is hung near the end of cross-arm; Comparison diagram 2 can find out obviously that this form of structure of the present utility model can make corresponding the reducing of distance between its cross-arm, and equal conditions can reduce the height of tower body down.Tower body of the present utility model can be installed a plurality of loops, twice or more than many times, the circuit that electric pressure is high is hung on the top of tower body, the circuit that electric pressure is low hangs over the bottom of tower body, the natural transmission power in every loop is significantly improved than every loop of conventional multiloop with tower comparatively speaking, also there has been obvious compression in the transmission line of electricity corridor, thereby reaches the purpose of this utility model.
