Description
Technical field
The utility model relates to a kind of iron towers of overhead power transmission lines, relates in particular to a kind of mountain area DC power transmission line Z-iron tower.
Background technology
The design of mountain area DC power transmission line steel tower often needs emphasis to consider distance to the ground and windage yaw impact, at uphill side, wire distance to the ground is nearest, in order to ensure minimum distance to the ground, steel tower height will increase a lot relative to the situation on level land, and in descending side, wire distance to the ground nargin is very large.The weight of tangent tower is very large by the impact of wind load, steel tower is higher, wind load on lead wire and earth wire and tower body is larger, steel tower is also heavier, at present the broad form of single time DC power transmission line tangent tower is the horizontal "T"-shaped steel tower of two-stage both at home and abroad, and steel tower earth wire support and cross-arm are symmetrically arranged, and the lead wire and earth wire load of the steel tower left and right sides is completely the same, this design is not only wasted material but also is made steel tower descending side when wind-engaging stressed comparatively large, is unfavorable for the balance keeping steel tower.Application number is the Chinese patent of 201310692367.X, have employed the structure of tower window, although had certain lifting at anti-lightning strike tripping operation aspect of performance, but because the reason that its window shape area is large causes it to bear lateral pressure increase when in the face of strong wind, if meet freezing weather again, when icing, meet with strong wind, easily make steel tower load-bearing tower line falling cannot be made disconnected and cause the loss of power accident.
Summary of the invention
A kind of structure that the purpose of this utility model is to overcome above-mentioned shortcoming and provides is simple, wind resistance good, can adapt to the complicated landform such as Sloping field in mountain area and the mountain area DC power transmission line Z-iron tower of largely minimizing steel tower weight reduction construction costs.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Mountain area of the present utility model DC power transmission line Z-iron tower, comprise tower leg and tower body, tower leg is fixedly connected on the below of tower body, wherein: the top of described tower body is provided with upper conductor cross-arm and upper ground wire cross-arm, and upper ground wire cross-arm is positioned at the top of upper conductor cross-arm; The middle and upper part of described tower body is provided with lower wire cross-arm and lower ground wire cross-arm, and lower ground wire cross-arm is positioned at the top of lower wire cross-arm; Substantially equal to ground distance to ground Distance geometry lower wire cross-arm of described upper conductor cross-arm.
Above-mentioned mountain area DC power transmission line Z-iron tower, wherein: described upper ground wire cross-arm, lower ground wire cross-arm are separately fixed on upper conductor cross-arm and lower wire cross-arm;
Above-mentioned mountain area DC power transmission line Z-iron tower, wherein: described upper ground wire cross-arm and lower ground wire cross-arm are also fixedly linked with tower body;
Above-mentioned mountain area DC power transmission line Z-iron tower, wherein: described tower leg is made up of upper tower leg and lower tower leg, the height of upper tower leg and lower tower leg presses actual landform can free adjustment.
The utility model compared with prior art, has obvious beneficial effect, as can be known from the above technical solutions: the top of tower body is provided with upper conductor cross-arm and upper ground wire cross-arm, and upper ground wire cross-arm is positioned at the top of upper conductor cross-arm; The middle and upper part of described tower body is provided with lower wire cross-arm and lower ground wire cross-arm, and lower ground wire cross-arm is positioned at the top of lower wire cross-arm; Substantially equal to ground distance to ground Distance geometry lower wire cross-arm of described upper conductor cross-arm.Such design makes full use of the height of physical relief, arrangement not contour about adopting earth wire support and cross-arm, under the prerequisite that satisfied left and right two polar conductor distance to the ground and windage yaw require, reduce descending side cross-arm height, make the wind load in this side lead wire and earth wire and the wind load on cross-arm all reduce to a certain extent, thus reach the weight reducing steel tower, reduce the object of the cost of engineering.
Upper ground wire cross-arm, lower ground wire cross-arm are separately fixed on upper conductor cross-arm and lower wire cross-arm.Such design makes ground wire cross-arm and upper conductor cross-arm be integrated, lower ground wire cross-arm and lower wire cross-arm are integrated, the structure of ground wire cross-arm and upper conductor cross-arm is diminished, save making material, thus steel tower weight can be reduced, cost-saving, be applicable to the little and freezing not too serious area of wind speed and use.
Upper ground wire cross-arm and lower ground wire cross-arm are also fixedly linked with tower body.Compare with upper a kind of structure, upper conductor cross-arm is not only connected with lower wire cross-arm, lower ground wire cross-arm respectively with upper ground wire cross-arm, its one end is also fixedly connected with tower body, such design adds the anti-pressure ability that a small amount of structure but strengthens steel tower greatly, can resist larger blast and weight, thus larger at wind and that freezing weather is more serious area is very applicable.Tower leg is made up of upper tower leg and lower tower leg, and the height of upper tower leg and lower tower leg can free adjustment.Steel tower can be made to adapt to make whole steel tower maintenance level by various complicated landform by the free adjustment of two tower legs, add the compliance of steel tower.
Mountain area of the present utility model DC power transmission line Z-iron tower, has that structure is simple, wind resistance good, can adapt to the complicated landform such as Sloping field in mountain area and largely reduces the feature that steel tower weight reduces construction costs.
