Description
Technical field
The present invention relates to a kind of aerial high-voltage power transmission line iron tower, a kind of specifically double tower window tangent tower.
Background technology
Along with China's rapid growth of economy; Electric utility and power grid construction have also obtained the development of advancing by leaps and bounds; The power transmission line of high pressure and super-pressure is increasing, and the contradiction of conventional transmission line of electricity passage and planning constantly manifests, especially in the plains region; Circuit corridor problem is more outstanding, therefore how to reduce electrical network particularly the high-tension line aisle spare become more and more important.At present, how optimize the responsibility place that the shared space of circuit is a line design under the prerequisite of instructions for use satisfying.
In conventional transmission line of electricity design, double loop tangent tower tower head comprises three layer conductor cross-arms and the tower neck that supports cross-arm, and the tower neck is connected with body of the tower.The double loop tangent tower adopts three layer conductor vertical arrangements; For guaranteeing the lower wire horizontal-shift; The neighbouring length that cross-arm adopted must differentiate, and generally we select short up and down, middle long mode, the invisible like this length that increases cross-arm; Cause circuit corridor span big, and the gap between the tower head can not make full use of.The crowded location in the corridor, the removal scope is big, and is less economical, and the ambient influnence face is bigger.In addition, the double loop tangent tower disposes " I " type drum type tower insulator string usually, has only an end to fix; The live wire end is swing easily under wind, causes potential safety hazard, for eliminating danger; Generally can tower head be done height does greatly; Not only consume a large amount of tower materials, and body of the tower wind load and lines wind load are big, lightning protection properties is poor.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of iron tower of power transmission line of new structure, can reduce tower height, reduce the span in circuit corridor, effectively optimize to take up room, and improve lightning protection properties simultaneously, practice thrift cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is:
Double tower window double loop tangent tower; Comprise tower head, body of the tower and be provided with the ground line bracket that hangs ground wire hanging wire point; Said tower head for by middle standing pillar, be positioned at the heel post of middle standing pillar both sides and be fixedly connected on middle standing pillar and double tower window construction that the crossbeam on heel post top constitutes; Said ground line bracket is fixedly connected on beam top, and the lower end of middle standing pillar and heel post is fixedly connected with the body of the tower top; Be provided with three layer conductors in said each tower window, wherein the middle standing pillar bilateral symmetry is provided with the hanging wire point that six suspension V-types are dangled and gone here and there; The heel post inboard also be respectively arranged with three with middle standing pillar hanging wire point position hang accordingly V-type dangle the string the hanging wire point.
Further improvement of the present invention is: the inboard following layer conductor hanging wire point place of said heel post is provided with a little cross-arm respectively; The middle layer conductor hanging wire point of said middle standing pillar both sides and following layer conductor hanging wire point place also are provided with same little cross-arm respectively.
Further improvement of the present invention is: said heel post is camber line shape, and the top of two heel posts is fixedly connected with the two ends of crossbeam respectively, and the lower end of heel post all is connected with the transition of body of the tower top through trapezium structure with the lower end of middle standing pillar.
Because the technological progress of having adopted technique scheme, the present invention to obtain is:
The present invention proposes a kind of double tower window double loop tangent tower.The double loop lead is suspended on the hanging wire point place that the V-type in the double tower window is dangled and gone here and there; Can satisfy the requirement of electric clearance, lightning protection, Insulation Coordination and lead wire and earth wire skew; The spacing between the horizontal direction is fully reduced the power transmission tower width of corridor by reduction greatly between the phase transmission pressure of both sides simultaneously; Tower head is arranged closely, has effectively reduced the tower head size, has reduced the tower head height; Through tower head optimization, the static corridor of circuit can reduce 33.3%, if consider the influence of routine " I " type drum type tower insulator string windage yaw again; Dynamically the corridor can reduce 51%, and the tower head height can reduce by 13.5%; The present invention has practiced thrift the engineering consumptive material, optimizes the line holding space, reduces trees felling of circuit corridor and housing demolition, has reduced construction costs.
The little cross-arm that layer conductor hanging wire point place is provided with under layer conductor hanging wire Dian Chu, following layer conductor hanging wire point place and the middle standing pillar in heel post just can satisfy the hanging wire requirement under the prerequisite that does not increase heel post and middle standing pillar width, help practicing thrift the tower material.
Heel post is camber line shape, and the top is connected with tower window crossbeam two ends; Heel post is connected with the transition of body of the tower top through trapezium structure with the middle standing pillar lower end, and not only profile is succinct, attractive in appearance, has increased the vertical, horizontal rigidity of tower head simultaneously, and is rational in infrastructure, solid durable.
