Abstract

The utility model discloses a medium and heavy ice area 110KV electric transmission line single circuit straight-line tower. The tower is integrally in a wine glass shape. The medium and heavy ice area 110KV electric transmission line single circuit straight-line tower comprises tower legs, a tower body, lower crank arms, upper crank arms, a wire cross arm and ground wire supports from bottom to top, wherein the wire cross arm is composed of a middle wire cross arm and two side wire cross arms, the vertical distance (H) between the upper plane of the ground wire supports and the lower plane of the side wire cross arms is 4.5 meters, the distance (W1) between two ground wire hanging points on the ground wire supports is 9.2 meters, and the distance (W2) between the two side wire cross arms is 13.2 meters. The medium and heavy ice area 110KV electric transmission line single circuit straight-line tower is capable of improving the requirements for the electrical distance in medium and heavy ice areas and the requirements for structural stress, and capable of improving the capacity of an iron tower for bearing imbalanced tension of ice coatings.

Description

In, heavy icing area 110KV transmission line of electricity single loop tangent tower
Technical field
The utility model relates to a kind of steel tower that erects power transmission lines, more particularly, relate in particular to a kind of be applicable to icing at 20mm with 110KV transmission line of electricity single loop tangent tower upper, heavy icing area.
Background technology
At the beginning of 2008, the large tracts of land ice damage that occurs in China Central China, some areas, East China has caused serious destruction to China's transmission line of electricity, and the 110KV transmission line of electricity is impaired especially serious.By to ice damage district's transmission line of electricity Field Research, make an on-the-spot survey and analysis is learnt, powerline ice-covering unbalanced tensile force, lead wire and earth wire and wire spacing deficiency are to cause ice damage district transmission line of electricity to fall one of major reason of tower.Because tangent tower bears the ability of icing unbalanced tensile force much smaller than anchor support, the destruction overwhelming majority that causes transmission line of electricity is to be caused by collapsing of tangent tower, thus State Grid Corporation of China in the modular design of issue in 2005 can not satisfy current specifications in, the electrical structure requirement of heavy icing area.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of be applicable to icing at 20mm with 110KV transmission line of electricity single loop tangent tower upper, heavy icing area, improve steel tower in, the electrical distance of heavy icing area requires and the structure stress requirement, improves the ability that steel tower bears the icing unbalanced tensile force.
for achieving the above object, in provided by the utility model, heavy icing area 110KV transmission line of electricity single loop tangent tower, comprise tower leg and the tower body that is fixedly connected on tower leg, be fixedly connected with two lower bent levers on tower body, crank arm being fixedly connected with on lower bent lever, be fixedly connected with middle wire cross-arm between the top of cranking arm on two, be fixedly connected with two limit wire cross-arms in the end of middle wire cross-arm, be fixedly connected with two earth wire supports on middle wire cross-arm, be fixedly connected with the ground wire hanging point on the top of earth wire support, vertical distance H between the lower plane of the upper plane of described earth wire support and limit wire cross-arm is 4.5m, distance W 1 between two ground wire hanging points on earth wire support is 9.2m, distance W 2 between the wire cross-arm of both sides is 13.2m.
The utility model adopts technique scheme, can improve steel tower in, the electrical distance of heavy icing area requires and the structure stress requirement, improves the ability that steel tower bears the icing unbalanced tensile force.
