Description
Technical field:
The utility model belongs to the iron tower of power transmission line technical field, relates in particular to a kind of extra-high voltage direct-current circuit 720/50 lead and uses the split anchor support.
Background technology:
At present, most anchor support structural configuration pattern all is consistent with common dried font anchor support layout pattern, and cross-arm stretches out that body of the tower length is longer, and bending resistance, the torsional property of iron tower are relatively poor, and iron tower is heavier, especially heavy icing area low-angle anchor support.
The utility model content:
Longer to dried font anchor support cross-arm extension elongation in the prior art, root is opened bigger, causes the very heavy technical problem of body of the tower load, and the utility model proposes following technical scheme:
A kind of extra-high voltage direct-current circuit 720/50 lead is used the split anchor support; Comprise that ground wire cross-arm, Construction and Maintenance are with frame, lead cross-arm, jumper wire rack, body of the tower and column foot; The split anchor support is made up of first Ji Ta and second Ji Ta; Column foot master material is fixed on the basis, and body of the tower integral body is trapezoidal-structure, and the below is fixedly connected with column foot master material; Wherein the body of the tower top of first Ji Ta connects with the ground wire cross-arm; The body of the tower medium position of second Ji Ta is connected with the lead cross-arm, and the end away from body of the tower on the lead cross-arm is connected with jumper wire rack, and the body of the tower top connects with the ground wire cross-arm, is connected with Construction and Maintenance away from an end of body of the tower on the ground wire cross-arm and uses frame.
The said first basic Tata body top is connected ground wire cross-arm structure triangular in shape with the ground wire cross-arm.
The said second basic Tata body medium position is connected lead cross-arm structure triangular in shape with the lead cross-arm.
The said second basic Tata body top connects with the ground wire cross-arm, ground wire cross-arm structure triangular in shape.
The said second basic tower Construction and Maintenance are flat trapezium structure with frame, the long base of trapezium structure down, hypotenuse is connected with the ground wire cross-arm.
The said second basic tower jumper wire rack is flat trapezium structure, the long base of trapezium structure up, hypotenuse is connected with the lead cross-arm.
Can find out from above-mentioned technical scheme; Compared with prior art; The split anchor support that the utility model adopts can satisfy the requirement of electric clearance; Described split anchor support lead wire and earth wire branch hangs on one's body two separate single-column Tatas, does not change between lead wire and earth wire and the alternate relativeness of lead simultaneously.Relatively horizontal-shift, ground wire are consistent with adjacent tangent tower to the aspects such as shielding angle of lead between two phase conductor horizontal arrangement, lead wire and earth wire, make that split anchor support structure is simpler, and moment of torsion is littler, and tower weight is lighter.
Description of drawings
Fig. 1 is the split anchor support iron tower structural representation that the utility model is applied in DC line.
Wherein: 1 is the ground wire cross-arm, and 2 use frame for Construction and Maintenance, and 3 is the lead cross-arm, and 4 is jumper wire rack, and 5 is body of the tower, and 6 is tower leg, and 7 is the lead hanging point.
The specific embodiment
To combine accompanying drawing that the utility model is described further below:
As shown in Figure 1, a kind of split anchor support, this split anchor support is divided into two Ji Ta, and wherein first Ji Ta comprises ground wire cross-arm, body of the tower, column foot, and second Ji Ta comprises that ground wire cross-arm, Construction and Maintenance are with frame, lead cross-arm, jumper wire rack, body of the tower, column foot.The body of the tower of two Ji Ta all is arranged as trapezoidal, and section is a square.Column foot master material is fixed on the basis, and the body of the tower below is fixedly connected with column foot master material.The said first basic Tata body top connects with the ground wire cross-arm, ground wire cross-arm structure triangular in shape.The said second basic Tata body medium position is connected lead cross-arm structure triangular in shape with the lead cross-arm.Compare with common anchor support, in the arrangement of split anchor support, cross-arm length reduces, and the lead hanging point position moves on on the body of the tower, and the toggle of the torque that produces is less, can reduce tower weight significantly.The said second basic Tata body top connects with the ground wire cross-arm, and ground wire cross-arm structure triangular in shape is connected with Construction and Maintenance on the ground wire cross-arm and uses frame, and said Construction and Maintenance are flat trapezium structure with frame, the long base of trapezium structure down, hypotenuse is connected with the ground wire cross-arm.
Embodiment shown in Figure 1 is mainly used in the situation of heavy icing area anchor support when the corner number of degrees are less in the DC power transmission line engineering; Be characterized in two of ground wires; It is terminal to be hung in two split tower ground coil holders arranged side by side, and lead is bipolar, is hung on two split tower lead hanging points arranged side by side.
This technology is applicable to ± 800kV electric pressure DC line in the low-angle anchor support of heavy icing area.
Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that the specific embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
