Description
Technical field:
The utility model belongs to used for transmission line iron tower technical field, relates in particular to a kind of 1000kV alternating current ultra-high voltage single-column overhung angle tower.
Background technology:
At present, the most angle tower arrangement that dangles all is consistent with the tangent tower layout pattern that dangles, and it is longer that cross-arm stretches out body of the tower length, bending resistance, the torsional property of iron tower are little, cause tower weight heavier, and the iron tower root is opened bigger, be not easy to the selection and the basic type selecting of tower position, the circuit cost is also higher.
The utility model content:
Longer at the angle tower cross-arm extension elongation of dangling of umbrella shape in the prior art, root is opened bigger, causes the very heavy technical problem of body of the tower load, the utility model proposes following technical scheme:
A kind of 1000kV alternating current ultra-high voltage single-column overhung angle tower, comprise ground wire cross-arm, Construction and Maintenance frame, lead cross-arm, body of the tower, column foot master material, the single-column angle tower overall structure of dangling is " Г " structure, column foot master material is fixed on the basis, body of the tower integral body is trapezoidal-structure, and the below is fixedly connected with column foot master material, and the body of the tower medium position is connected with the lead cross-arm, the body of the tower top connects with the ground wire cross-arm, and the end away from body of the tower on the ground wire cross-arm is connected with the Construction and Maintenance frame.
Described body of the tower medium position is connected with the lead cross-arm, lead cross-arm structure triangular in shape, and leg-of-mutton obtuse angle is downward.
Described body of the tower top connects with the ground wire cross-arm, ground wire cross-arm structure triangular in shape, and the base is up.
Described Construction and Maintenance are flat trapezium structure with frame, the long base of trapezium structure up, hypotenuse is connected with the ground wire cross-arm.
From above-mentioned technical scheme as can be seen, compared with prior art, among the embodiment of the present utility model, the single-column that the adopts angle tower that dangles can satisfy the requirement of electric clearance, adopt single-column among the utility model embodiment angle tower two loop line road branches that dangle to hang on one's body two separate single-column Tatas, do not change between lead wire and earth wire and the alternate relativeness of lead simultaneously.Be arranged vertically up and down at phase conductor, horizontal-shift, ground wire are consistent with adjacent tangent tower to the aspects such as shielding angle of lead relatively between lead wire and earth wire, make that the single-column angle tower structure of dangling is simpler, tower weight is lighter; The reducing of single Ta Genkai makes the single-column angle tower that dangles strengthen greatly the compliance of landform, geological conditions.
