Description
Technical field
The utility model relates to a kind of transmission line with four-circuit on single tower tangent tower, belong to the overhead transmission line iron tower.
Background technology
The development of China's electric utility is at present advanced by leaps and bounds, and special (surpassing) high pressure, big capacity, multiloop carry oneself to become the inexorable trend that electric power is carried, but ultra-high-tension power transmission line causes various contradictions more and more outstanding owing to taking too much, the wide problem in corridor.Extra-high voltage 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 super-pressure is main with the double loop mainly with tower multiloop transmission line of electricity, along with the growing tension of circuit corridor resource, also begins to apply to engineering design with tower four loops, has greatly reduced the circuit corridor.
At present there is lead horizontally and two kinds of vertical arrangements with the practice of four times power transmission towers of tower.Two kinds of arrangements respectively have superiority, and the former invests relatively low, and cost is practiced thrift about 40% than the latter; But width of corridor is relatively large.Comparatively speaking, not under the unusual crowded situation in the circuit corridor, no matter adopt is that economic benefit or social benefit all have bigger advantage four times with tower horizontally.Therefore, actual in conjunction with concrete engineering, arrange to horizontally further optimizing tower head with four times power transmission towers of tower, compress width of corridor to greatest extent and have important practical significance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and the transmission line with four-circuit on single tower tangent tower that a kind of cost is reasonable, practice thrift in the corridor is provided.
The utility model is realized through following technical scheme: it mainly comprises tower leg, body of the tower, tower head and is fixedly connected on the wire insulation substring on the tower head, described tower head by the lead cross-arm, line bracket and form with the last body of the tower that body of the tower is connected together mutually; Described lead cross-arm comprises cross-arm, middle cross-arm and following cross-arm, and they are arranged to three layers in the bilateral symmetry of last body of the tower, and are fixedly connected with last body of the tower respectively.
Described wire insulation substring comprises two kinds of " I " type insulator string and " V " type insulator strings, wherein adopts " I " string to connect with the lead cross-arm in the tower head outboard wire, adopts " V " to go here and there with the lead cross-arm and go up body of the tower in the tower head inboard wire and connects.
The member of said lead cross-arm all adopts angle steel to process, and takes into full account that node on the cross-arm is many, the situation of complex connection, gives full play to that the angle iron component node processing is succinct, the advantage of convenient processing and installation; The main bearing member of said tower leg and body of the tower all adopts steel pipe to process, and gives full play to the advantage that steel pipe build coefficient is little, supporting capacity is high, further reduces tower weight.
Compared with prior art; The beneficial effect of the utility model is: at first through adopting " V " string form to compress the cross-arm floor height to inboard wire insulation substring; Adopt " I " string form to compress cross-arm length to outside wire insulation substring, optimized the tower head structure, reduced the tower head size; Thereby reduce the circuit width of corridor effectively, reduce tower material consumption, improved the transmission power of unit corridor; Secondly, on member was selected, stressed and node connections needs choose reasonable steel pipe and angle steel form according to the iron tower different parts were given full play to the advantage of various members, reduced tower weight, conveniently processed and construction and installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Label shown in the figure is: go up cross-arm 1, middle cross-arm 2, down cross-arm 3, line bracket 4, go up body of the tower 5, " I " type insulator string 6, " V " type insulator string 7, tower head 8, body of the tower 9, tower leg 10.
To combine accompanying drawing that the utility model is done further to describe in detail below.Shown in Figure 1, the utility model mainly comprises tower leg 10, body of the tower 9, tower head 8 and is fixedly connected on the wire insulation substring 6,7 on the tower head; Described tower head 8 by the lead cross-arm, line bracket 4 and form with the last body of the tower 5 that body of the tower 9 is connected together mutually; Described lead cross-arm comprises cross-arm 1, middle cross-arm 2 and following cross-arm 3, and they are arranged to three layers in the bilateral symmetry of last body of the tower 5, and are fixedly connected with last body of the tower 5 respectively.
As a kind of improvement, for fully compressing width of corridor and tower head height, outboard wire adopts " I " type insulator string to connect with cross-arm, and inboard wire adopts " V " type insulator string and cross-arm and goes up body of the tower and connects.
As a kind of improvement, the cross-arm member all adopts angle steel, gives full play to that the angle iron component node processing is succinct, the advantage of convenient processing and installation; The main bearing member of tower leg and body of the tower all adopts steel pipe, gives full play to the advantage that steel pipe build coefficient is little, supporting capacity is high, reduces tower weight.
At last, it should be noted that above what enumerate only is the specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
