Background technology
Early in the twentieth century, newly-built 220kV transformer station 110kV outlet is fewer, and 110kV outlet all adopts single time overhead outlet.In the recent period, along with 110kV transformer station increases the increase of layouting newly, 110kV outlet Requirement Increases, around transformer station, transmission line corridor is more crowded, and this just requires that 110kV outlet adopts cable and overhead wire mixing outlet, and double-circuit line must be adopted to joint use.The 110kV circuit originally set up adopts sizing terminal angle head tower (7738-12) usually, this sizing terminal angle head tower, by tower body, upper strata cross-arm, middle level cross-arm, lower floor's cross-arm, arrester, composite insulator, transmission pressure and cable shoe, its weak point is: this sizing terminal angle head tower (7738-12) can only meet transformer station's overhead outlet, when transformer station's transmission line corridor is nervous, when double back overhead outlet safe distance does not meet the demands, transformer station's overhead outlet can be realized one time, cannot simultaneously overhead outlet twice, significantly limit transformer station's outlet.
Summary of the invention
The purpose of this utility model is to provide that a kind of cost is low, power supply safety reliable, and simple installation, effectively combines cable run with overhead wire, guarantee transformer station's powered operation reliable 110kV cable double-circuit line terminal tower.
In order to reach above object, the technical scheme that the utility model adopts is: this kind of 110kV cable double-circuit line terminal tower, comprise tower body, upper strata cross-arm, middle level cross-arm, lower floor's cross-arm, transmission pressure, arrester, composite insulator and cable shoe, it is characterized in that: be arranged with two upper strata cross-arms from top to bottom successively on the top of tower body, two middle level cross-arms, Liang Ge lower floor cross-arm and two bottom cross-arms, between the cross-arm outer end, upper strata and cross-arm outer end, middle level of the same side, between the cross-arm outer end, middle level of the same side and lower floor's cross-arm outer end, arrester and composite insulator is all fixed with between lower floor's cross-arm outer end of the same side and bottom cross-arm outer end, the link of arrester and composite insulator and cable shoe, transmission pressure is fixedly connected with, be equally spaced in the bottom of tower body and be fixed with cross bar, cross bar is provided with six anchor ears corresponding respectively with six roots of sensation cable.
Be provided with six cable sleeves bottom described tower body, the bottom of every root cable is all set in corresponding cable sleeve.
The unit cable on described tower body top is fixed on tower body by single anchor ear and nut.
Described upper strata cross-arm, middle level cross-arm, lower floor's cross-arm are identical with the length of bottom cross-arm, and length is 3500-5000mm, and upper strata cross-arm, middle level cross-arm, lower floor's cross-arm and bottom cross-arm are positioned at same plane.
Described anchor ear is in " U " type, and two free ends of anchor ear to be each passed through on cross bar after corresponding through hole and to fix with nut.
The beneficial effects of the utility model are: when 110kV circuit adopts cable outlet, shorten the pole and tower design process-cycle, and be easy to construction, be convenient to order goods, process, greatly reduce the duplication of labour of technician, improve operating efficiency, decrease fund input.
