Description
Technical field
The utility model relates to a kind of power transmission tower, especially relates to a kind of high voltage power transmission tower.
Background technology
The developable electric resources more than 60% of China is western in China, but more than 60% electricity needs is in Deposits in Eastern Coastal China area, with regard to needing, the electric power in western part is transported to east like this.
In high-tension electricity transmits, boost to high pressure carry out aerial cables conveying be a kind of mode the most common, common electric pole is due to highly too low, insufficient strength cannot become the support of ultra-high-tension power transmission line cable laying, in the middle of existing transmission line of electricity, ultra-high-tension power transmission line needs the high voltage power transmission tower that some endurance are larger, also require that there is larger profile simultaneously, therefore in order to reduce transmission losses, improve transmission of electricity quality, the laying being carried out ultra-high-tension power transmission line by high voltage power transmission tower effectively solves this problem.
Utility model content
The purpose of this utility model is exactly provide a kind of high voltage power transmission tower of safety and firmness to overcome defect that above-mentioned prior art exists
The purpose of this utility model can be achieved through the following technical solutions:
A kind of high voltage power transmission tower, it is characterized in that, comprise column foot, column foot, tower body, tower top and cross-arm, described column foot, column foot, tower body and tower top are fixedly connected sequentially from down to up, described cross-arm is arranged on tower top, described cross-arm is provided with insulator string, and described column foot, tower body and tower top form quadrangular trussed construction by horizontal material, tiltedly material and web member by screw is fixing.
Described cross-arm comprises 1 ground wire cross-arm and 2 wire cross-arms, and described ground wire cross-arm is arranged on tower top top, and described wire cross-arm is arranged on immediately below ground wire cross-arm.
Described column foot is concrete structure.
Described high voltage power transmission tower material is high-strength steel.
Described column foot has 4.
Preferably, described tower body is provided with multiple crossbeam with a determining deviation.
Preferably, described insulator string has 4-6, is symmetrical arranged with cross-arm center line.
Compared with prior art, the utility model has the following advantages:
One, safety and stability, tower bar adopts quadrangular trussed construction and material is high-strength steel, ensure that the steadiness of tower bar.
Two, applied widely, tower bar itself is provided with 1 ground wire cross-arm and 2 wire cross-arms and multiple insulator string, can adapt to different line requirements.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
A kind of high voltage power transmission tower, it is characterized in that, comprise column foot 1, column foot 2, tower body 3, tower top 4 and cross-arm 5, described column foot 1, column foot 2, tower body 3 are connected from down to up successively with tower top 4, described cross-arm 5 is arranged on tower top 4, described cross-arm 5 is provided with insulator string, and described column foot 2, tower body 3 and tower top 4 form quadrangular trussed construction by horizontal material, tiltedly material and web member by screw is fixing.
Shanghai, Zhejiang, Huaihe River extra high voltage line comprises the western three-line in Huainan ~ Wan Nan, Wan Nan ~ Zhe Bei, Zhe Bei ~ Shanghai, and wherein Huainan ~ south, Anhui circuit divides in order to three sections.Therefore, in this project, establish 5 sections of independently circuits altogether, each section has all used a large amount of shaft towers,
Overhead line structures are larger on line parameter circuit value impact, the straight line pole adopting consumption maximum in the simulation of this project each section lead is to simulate the shaft tower of whole piece circuit, according to the data that designing institute provides, the western circuit in Huainan ~ Shanghai is according to having used diagram tower bar, its structure as shown in Figure 1, shaft tower exhale height to get full section shaft tower on average exhale height, insulator string is long is 10.5m.
