Description
One, technical field
The utility model relates to a kind of transmission pressure, especially a kind of transmission pressure that is adapted to open-air length apart from transmission of electric energy.
Two, background technology
Electric energy is used widely as main energy sources, but the conveying of electric energy need be used transmission pressure, therefore transmission pressure is important electric device, existing transmission pressure all is flat conductor or column type lead, can not effectively alleviate windage, when the conducting wire was subjected to wind, rocking tendency reached, and fragile or short circuit causes the accident; On transmission pressure, also easily assemble aerial junk, cause fouling on the circuit, cause aging circuit, corrosion impaired, make the security performance of transmission pressure low.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of transmission pressure, has improved the security performance of transmission pressure.
For achieving the above object, the technical scheme that the utility model is taked is: include the transmission pressure body, on the cross section of transmission pressure body, the central point of transmission pressure body is set to origin of coordinates O and sets up X, the Y coordinate system, the central point that is set to the transmission pressure body at the outer contour of the cross section of the transmission pressure body in first interval is the parabola of initial point O, the central point that is set to the transmission pressure body at the outer contour of the cross section of the transmission pressure body in second interval is the parabola of initial point O, the central point that is set to the transmission pressure body at the outer contour of the cross section of the transmission pressure body in the 3rd interval is the parabola of initial point O, the central point that is set to the transmission pressure body at the outer contour of the cross section of four-range transmission pressure body is the parabola of initial point O, and the outer contour of the cross section of transmission pressure body is set to by first interval, second interval, the curve that the 3rd interval and four-range parabola are formed.
Transmission pressure is bridged on the power transmission tower, just can make and transmit electric energy between the strange land mutually, because having designed the outer contour of transmission pressure body is parabola, reduced windage, reduced amplitude of fluctuation, other foreign matter is no longer easily gathered on the transmission pressure body, therefore improved the security performance of transmission pressure.
The utility model has designed, the central point that is set to the transmission pressure body at the outer contour of the cross section of the transmission pressure body in first interval is the parabola of initial point O, be set to Y-axis symmetrical at the outer contour of the cross section of the transmission pressure body in second interval with outer contour at the cross section of the transmission pressure body in first interval, be set to the X axle symmetrically at the outer contour of the cross section of the transmission pressure body in the 3rd interval, be set to Y-axis symmetrical with outer contour at the cross section of the transmission pressure body in the 3rd interval at the outer contour of the cross section of four-range transmission pressure body with outer contour at the cross section of the transmission pressure body in second interval.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
Five, embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include the transmission pressure body, on the cross section of transmission pressure body, the central point of transmission pressure body is set to origin of coordinates O and sets up X, the Y coordinate system, coordinate+X and+interval that Y forms is set to first interval 1, coordinate-X and+interval that Y forms is set to second interval 2, coordinate-X and-interval that Y forms is set to the 3rd interval 3, coordinate+X and-interval that Y forms is set to the 4th interval 4, the central point that is set to the transmission pressure body at the outer contour of the cross section of the transmission pressure body in first interval 1 is the parabola of initial point O, be set to Y-axis symmetrical at the outer contour of the cross section of the transmission pressure body in second interval 2 with outer contour at the cross section of the transmission pressure body in first interval 1, be set to X-axis symmetrical at the outer contour of the cross section of the transmission pressure body in the 3rd interval 3 with outer contour at the cross section of the transmission pressure body in second interval 2, be set to Y-axis symmetrically with the outer contour at the cross section of the transmission pressure body in the 3rd interval 3 at the outer contour of the cross section of the transmission pressure body in the 4th interval 4, the outer contour of the cross section of transmission pressure body is set to by first interval 1, second interval 2, the parabola in the 3rd interval the 3 and the 4th interval 4 is formed.
In the present embodiment, parabolical parameter is set to first the interval the 1 and the 4th interval 4 and is X=-A
2Y
2+ B; The the 4th the interval the 2 and the 4th interval 3 is X=A
2Y
2-B, A is set to 2mm, and B is set to 4mm.
Transmission pressure is bridged on the power transmission tower, just can uses and transmit electric energy between the strange land mutually.
Make it the utlity model has characteristics:
1, owing to the outer contour that has designed the transmission pressure body is a parabola, parabola can be than the more effective minimizing windage in the face of cylinder, and windage reduces can reduce lead wind swing, reduces harness damage.
2, owing to the outer contour that has designed the transmission pressure body is a parabola, parabolical increases the lead athwartship moment, also effectively reduces the lead swing, reduces harness damage;
