Background technology
Present stage, along with socioeconomic fast development, high-voltage fence also fast development gets up.Dotted electrical network interts in large ground, and line corridor is more and more nervous, Fei Yeyong is more and more higher in occupation of land clear compensation.In order to alleviate this phenomenon, get more and more with shaft tower double loop, multi circuit transmission lines.
The double-circuit line of current employing is joint used shaft tower and is provided with two groups of cross-arms, is separately positioned on the both sides of shaft tower.Double-circuit line joint use double T connect time, due to double back T link, to joint use direction consistent, and a loop line road connects by the direct T of this group cross-arm, and another loop line road need around the opposite side to shaft tower, and then continuation erection completes circuit T and connects.Scheme conventional at present adopts cable to guide to underground, and then be connected to next base shaft tower of T link, and adopt this kind of mode to complete circuit double T and connect, not only construction costs is high, increases floor space, and circuit operation maintenance is inconvenient, and potential safety hazard is many.
Summary of the invention
The purpose of this utility model be to provide a kind of cost low, convenient for installation and maintenance, joint use and not use cable when circuit double T connects, do not increase floor space, engineering cost can be reduced, line security hidden danger can be reduced completing double back, and the simple double-circuit line of structure joint uses double T extension bar tower.
In order to reach above object, the technical scheme that the utility model adopts is: this double-circuit line joint uses double T extension bar tower, comprise tower body, first group of upper strata cross-arm, first group of middle level cross-arm and first group of lower floor's cross-arm, first group of upper strata cross-arm, first group of middle level cross-arm and first group of symmetrical left and right sides, top being fixedly installed on tower body of lower floor's cross-arm, first group of upper strata cross-arm, first group of middle level cross-arm and first group of lower floor's cross-arm are positioned at same plane, it is characterized in that: before and after the top of described tower body, bilateral symmetry is fixed with second group of upper strata cross-arm, second group of middle level cross-arm and second group of lower floor's cross-arm, second group of upper strata cross-arm, the same plane at second group of middle level cross-arm and second group of lower floor's cross-arm place and first group of upper strata cross-arm, the plane orthogonal at first group of middle level cross-arm and first group of lower floor's cross-arm place.
Second group of described upper strata cross-arm is between first group of upper strata cross-arm and first group of middle level cross-arm; Second group of middle level cross-arm is between first group of middle level cross-arm and first group of lower floor's cross-arm; Second group of lower floor's cross-arm is positioned at below first group of lower floor's cross-arm.
The top of described tower body is fixed with lightning rod.
The beneficial effects of the utility model are: structural safety, cost are low, double-circuit line joint use double T connect time, can effectively reduce construction costs, reduce floor space, reduce circuit run hidden danger.
