Description
Technical field
The utility model relates to a kind of steel tower erected power transmission lines, and more particularly, particularly relates to a kind of 220kV transmission line of electricity single loop anchor support.
Background technology
220kV transmission line of electricity single loop anchor support in State Grid Corporation of China's universal design generally adopts " doing " font (mainly containing 2A, 2B, 2C design module), it exhales high all at more than 18.0m, when 220kV transmission line of electricity passes through the circuit of 500kV and above voltage levels, the safe distance of newly-built 220kV transmission line of electricity to 500kV and above voltage levels circuit may be caused not meet code requirement because 220kV steel tower is exhaled higher.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of 220kV transmission line of electricity single loop anchor support, this tower can ensure that wire meets code requirement over the ground and to by the safe distance passing through wire when passing through 500kV and above voltage levels circuit.
For achieving the above object, 220kV transmission line of electricity single loop anchor support provided by the utility model, comprise tower leg and be fixedly connected on the tower body on tower leg, described tower body is fixedly connected with two lower bent levers, crank arm on lower bent lever is fixedly connected with, wire cross-arm in being fixedly connected with between the top that two are cranked arm, two limit wire cross-arms are connected with at the end winding support of middle wire cross-arm, middle wire cross-arm is fixedly connected with two earth wire supports, vertical distance H between the upper surface of described earth wire support and the lower surface of limit wire cross-arm is 4m, distance W1 between the ground wire hanging point of two earth wire support ends is 11.7m, distance W2 between the conducting wire hanging point of both sides wire cross arm end is 13.4m.
The utility model anchor support tower adopts wine glass-shaped design, makes wire horizontal, mountain region and plains region all applicable, when ensureing to pass through 500kV and above voltage levels circuit, wire meets code requirement over the ground and to by the safe distance passing through wire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of the utility model tower body part.
In figure: 1-tower leg; 2-tower body; 3-lower bent lever; 4-cranks arm; Wire cross-arm in 5-; 6-limit wire cross-arm; 7-earth wire support; The main material of 8-; The oblique material of 9-; 10-assists material.
Detailed description of the invention
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 1, the utility model 220kV transmission line of electricity single loop anchor support, its tower entirety is in wine glass-shaped, adopt Q345 and Q235 hot rolling equal angle steel as being subject to dead-wood, add the space truss structure that the connecting elementss such as upper steel plate, bolt, pin nail and packing ring assemble, described angle steel has dividing of main material 8, tiltedly material 9 and auxiliary material 10, as shown in Figure 2, main material is stressed member, in order to the geometric invariance and rod member that ensure iron tower structure stability and reduce the slenderness ratio of component and be provided with necessary oblique material and auxiliary material.
The utility model 220kV transmission line of electricity single loop anchor support, comprise from the bottom to top tower leg 1, tower body 2, lower bent lever 3, on crank arm 4, wire cross-arm and earth wire support 7, described wire cross-arm is made up of a middle wire cross-arm 5 and two limit wire cross-arms 6.
Described tower leg 1 adopts complete unequel leg extension to design, by 1.5 meters of differential settings, this kind of design can the arbitrary orientation length that regulates steel tower to connect leg change with adaptation to the ground, to realize cooperatively interacting of tower leg and landform, the quantity of sword cutting edge of a knife or a sword excavation can be reduced when constructing, reducing workload.In addition, the damaged condition of this kind of design to the landform around steel tower, landforms and vegetation drops to minimum, is beneficial to environmental protection.
Described tower body 2 is fixedly connected on tower leg 1, and the cross section of this tower body 2 is square, and the tower body of square structure can improve the structure stress situation of steel tower in light ice formation, makes steel tower better stressed.
Tower body 2 is fixedly connected with two lower bent levers 3, lower bent lever 3 is fixedly connected with and cranks arm 4, two are cranked arm 4 top between be fixedly connected with in wire cross-arm 5, for hanging a wire in the centre position in transmission line of electricity, two limit wire cross-arms 6 are connected with at the end winding support of middle wire cross-arm 5, for hanging another two wires in transmission line of electricity, three wires be suspended on wire cross-arm 5 and both sides wire cross-arm 6 are horizontally, middle wire cross-arm 5 is fixedly connected with two earth wire supports 7, for hanging ground wire.
Vertical distance H between the upper surface of described earth wire support 7 and the lower surface of limit wire cross-arm 6 is 4m, and the distance W1 between the ground wire hanging point of two earth wire support 7 ends is 11.7m, and the distance W2 between the conducting wire hanging point of wire cross-arm 6 end, both sides is 13.4m.What the utility model adopted this kind of design effectively can reduce steel tower exhales height, ensure newly-built circuit can safety pass through 500kV and above voltage levels circuit, with entering and wire safe distance over the ground can being met.
