Description
Technical field
The utility model belongs to grid equipment field, relates in particular to a kind of novel pair of difference tower using when 66 kilovolts of transmission line with four-circuit on single tower T connect difference of being applicable to, and is applicable to high-pressure delivery electrical network.
Background technology
Along with becoming increasingly conspicuous of power grid construction and local economy contradiction, electric power corridor resource is more and more nervous, aerial power transmission line to levy occupation of land very difficult, like this design of transmission line of electricity is also proposed to the more requirement of Gao Gengxin, for tackling this contradiction, design concept with tower four loops forms, and develops from local path bottleneck to overall situation all frontsization.
The transmission line of electricity of current 66 kilovoltage grades only uses in China some areas, mainly be distributed in the areas such as three provinces in the northeast of China, 66 KV transmission lines are often that a circuit is several 66 kv substation power supplies, the mode that normally connects difference by T realizes, will use like this T and connect difference tower, do not have four loop double Ts to connect this tower of difference tower in " but the project of transmitting and converting electricity universal design 110(66 of State Grid Corporation of China) kV transmission line of electricity fascicle (version in 2011) ", in engineering in the past, when occurring that four loop T connect while being two double loop difference shelves, utilize the following two kinds of connected modes of the general employing of existing four loop anchor supports:
The right side phase line cross arm end A1 of lower floor, B1, C1(corresponding A, B, a C three-phase by four loop anchor supports) hanging wire, be connected to T and connect the double loop shaft tower one side cross-arm of difference.
Another time returned strain rod tower at the newly-built base list in the left side of four Loop Steel Towers, the lower floor of shaft tower and four loop anchor supports left side phase line cross arm end A2, B2, C2 hanging wire thus, then return shaft tower by newly-built list and pass through four loop line roads and be connected to T and connect the double loop shaft tower opposite side cross-arm of difference.
The right side phase line cross arm end A1 of lower floor, B1, C1(corresponding A, B, a C three-phase by four loop anchor supports) hanging wire, be connected to T and connect the double loop shaft tower one side cross-arm of difference.
Another time be new processing one deck cross-arm D2 below the four double-circuit line orlop cross-arm C2 of Loop Steel Tower lower floor.
Between A2, B2, C2, D2, adopting mode under cable leading to be connected to T to connect the double loop shaft tower opposite side cross-arm of difference.
In above-mentioned two kinds of connected modes, there is following problem:
For the first connected mode, a newly-built base list returns strain rod tower transition, has caused shaft tower amount, circuit corridor, has levied the increase of occupation of land, and in the time passing through four loop line roads, scissors crossing distance does not easily meet code requirement.If increase the height of exhaling of four Loop Steel Towers before design, also waste steel, increase construction costs.
Adopt the connected mode under cable leading for the second, although saved the consumption of shaft tower material, levy the expense of occupation of land and corridor cleaning, but adopt the connected mode under cable leading to bring inconvenience to operation maintenance, construction costs aspect is also far away higher than the cost that adopts built on stilts connected mode.
Above two kinds of connected modes are unfavorable for responding " resource-conserving " " environmentally friendly " of Guo Wang company, save corridor resource, reduce the enforcement of building and moving overall cost.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, safe and reliable, consumptive material is low 66 kilovolts connect difference tower with tower four loop double Ts.
The utility model is to realize like this, a kind of 66 kilovolts connect difference tower with tower four loop double Ts, this difference tower comprises the tower head of top-hung ground wire, tower body and tower seat, on tower body, be provided with in the same way successively from top to bottom double loop, three-phase upper strata phase line cross-arm and three-phase lower floor double loop phase line cross-arm, on this tower body, be also provided with double loop, upper strata phase line cross-arm or the perpendicular three-phase double loop double T of lower floor's double loop phase line cross-arm direction and connect difference cross-arm, the described order according to from the bottom up, double loop double T connects difference cross-arm and lower floor's double loop phase line cross-arm distributes according to the order of ABABAB, wherein A represents that double loop double T connects difference cross-arm, B represents lower floor's double loop phase line cross-arm.
Further, between the phase line horizontal stroke of double loop, three-phase upper strata and the spacing that connects between difference cross-arm and adjacent lower floor's double loop phase line cross-arm of double loop double T be 3～4m.
