Abstract

Provided is a vertical arrangement cup type tangent tower, its characterized in that: tower head includes the ground wire support, goes up the cross arm, down the cross arm crank arm on, and crank arm under and, go up the cross arm including being used for hanging the ground wire cross arm of ground wire and the wire cross arm that hangs the transmission pressure to crank arm on as the horizontal support at top, lower cross arm is located tower head's middle part for hang the transmission pressure, and as on crank arm the bottom horizontal support, go up crosspiece, the cross arm extremely window of (b) (b) wire of constitutions (b) (b) A (b) (b) of cranking arm on and down, lower cross arm, the extremely window of (b) (b) wire of partly (b) (b) B (b) of constitution (b) of cranking arm on and of cranking arm down, upper and lower wire all adopts (b) (b) V (b) (b) to go here and there and hangs. The utility model discloses a wire vertical arrangement mode, wire are located the central line of tower, and line channel can effectually be saved to by a wide margin the width that has reduced the body of the tower, reduces the housing demolition volume, has better economic benefits and social.

Description

± 800kV vertical arrangement cup type tangent tower

Technical field

the utility model relates to power transmission sequence ± 800kV cup type tangent tower, especially relates to one ± 800kV vertical arrangement cup type tangent tower.

Background technology

dC power transmission line is generally bipolar same tower transmission of electricity, the two poles of the earth horizontal arrangement, the requirements such as the field intensity of safe operation, electric clearance and distance to the ground can be met, but along with constantly carrying out of extra-high voltage project, transmission line of electricity often enters developed area, this area's local-style dwelling houses and factory building is intensive, corridor is crowded, removal is difficult, horizontal tangent tower cross-arm is long, floor space is large, has been difficult to meet engineering demand.

Utility model content

the purpose of this utility model is to provide one ± 800kV vertical arrangement cup type tangent tower, greatly reduces width of corridor, reduces removal quantity.

for achieving the above object, the utility model provides a kind of vertical arrangement cup type tangent tower, it is characterized in that:

tower head comprise earth wire support, upper cross-arm, lower cross-arm, on crank arm and lower bent lever; Upper cross-arm comprises ground wire cross-arm for hanging ground wire and hangs the wire cross-arm of transmission pressure, and as the horizontal support at top of above cranking arm, lower cross-arm is positioned at the middle part of described tower head, for hanging transmission pressure, and as the horizontal support bottom above cranking arm; Top rail, lower cross-arm and on to crank arm the window of composition A polar conductor, lower cross-arm, lower bent lever and on the window of part composition B polar conductor of cranking arm, upper lower wire all adopts V to go here and there and hangs.

the utility model adopts wire vertical arrangement, and wire is positioned on the center line of tower, significantly reduces the width of tower body, effectively can save line channel, reduces housing demolition amount, has good economic benefit and social benefit.

Accompanying drawing explanation

accompanying drawing 1 is structural representation of the present utility model.

Detailed description of the invention

with reference to accompanying drawing 1, in detailed description of the invention of the present utility model, tower head comprise crank arm 1, lower bent lever 2, earth wire support 3, upper cross-arm 4 and lower cross-arm 5; Upper support structure comprises for hanging the earth wire support 3 of ground wire and hanging the upper cross-arm 4 of A polar conductor, and as the horizontal support at 1 top of above cranking arm, lower cross-arm 5 is positioned at the middle part of described tower head, for hanging B polar conductor, and as the horizontal support of above cranking arm bottom 1; Top rail 4, lower cross-arm 5 and on to crank arm the window of 1 composition A polar conductor, lower bent lever 1, on crank arm 2 and lower cross-arm 5 form the window of B polar conductor; The sequence of tower head is: lower bent lever 2, on crank arm 1, lower cross-arm 5, upper cross-arm 4, earth wire support 3; Upper lower wire all adopts V to go here and there and hangs, and hanging wire order is followed successively by: ground wire, A polar conductor, B polar conductor.

Claims

1. a vertical arrangement cup type tangent tower, is characterized in that: tower head comprise earth wire support, upper cross-arm, lower cross-arm, on crank arm and lower bent lever; Upper cross-arm comprises ground wire cross-arm for hanging ground wire and hangs the wire cross-arm of transmission pressure, and as the horizontal support at top of above cranking arm, lower cross-arm is positioned at the middle part of described tower head, for hanging transmission pressure, and as the horizontal support bottom above cranking arm; Top rail, lower cross-arm and on to crank arm the window of composition A polar conductor, lower cross-arm, lower bent lever and on the window of part composition B polar conductor of cranking arm, upper lower wire all adopts V to go here and there and hangs.
