Description

A kind of ultra-high voltage transmission tower
Technical field
This utility model is related to power system electrical equipment, in particular, is related to a kind of ac transmission transmission tower.
Background technology
It is ± 800kv and above technology of transmission of electricity that extra-high voltage direct-current transmission technology refers generally to electric pressure.Using UHV transmission technology can reduce the tower material index of unit transmission capacity, base values, width of corridor etc., when reducing distance conveying Electric energy loss.
With extra high voltage line shaft tower root open increasing, increasing shaft tower can not meet complexity landform will Ask, especially in the karst landform area that landform is precipitous, ridge is narrow, the selection of tower position is particularly difficult, in tower position straitly Section design rootlet opens steel tower very important meaning.Simultaneously as mountain area design use in the discrepancy in elevation described in electric power pylon relatively Greatly, electric field space is compact, has uniform distances and can not meet the engineering defect of safe distance it is impossible to meet compact transmission line Arrangement demand.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of AC extra high voltage electric power pylon, is ensureing normally The technical problem of mountain area reasonable Arrangement electric power pylon is can solve the problem that while transmission of electricity task.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of AC extra high voltage electric power pylon it is characterised in that: include tower body and be located at the tower body first half tower shoulder, tower body Bottom be provided with column foot, upper cross-arm that tower body includes from top to bottom setting gradually, lower cross-arm, upper cross-arm is symmetrically set with Support, is inclined to set between described support and upper cross-arm, and angle therebetween is 20 ° -30 °;The width e of described tower shoulder with The ratio of horizontal range w of described column foot is between 1.5-2;Described upper cross-arm right-hand member is provided with interior phase insulator chain, described on It is provided with interior phase strain insulator-string hanging point, one end first elastic adapter ring of interior phase strain insulator-string is by described interior phase strain insulator in the middle part of cross-arm String hanging point is connected with upper cross-arm, and the other end is connected with described interior phase insulator chain by interior phase wire jumper;Described lower cross-arm left end sets It is equipped with foreign minister's insulator chain, in the middle part of described lower cross-arm, be provided with foreign minister's strain insulator-string hanging point, one end second bullet of foreign minister's strain insulator-string Property connection ring be connected with lower cross-arm by described foreign minister's strain insulator-string hanging point, the other end passes through foreign minister's wire jumper and described foreign minister's insulator Series winding connects.
Further, the angle between described support and described upper cross-arm is 25 °.
Further, the described width e of tower shoulder and the ratio of horizontal range w of described column foot are 1.8.
Technique effect of the present utility model and advantage: this AC extra high voltage electric power pylon can meet vertical in mountain terrain Tower, has enough mechanical strengths, meets the internal force under various operating modes and deformation requirements, is conducive to tower position safety and environmental conservation Require, decrease steel usage amount simultaneously, saved column foot land expropriation cost and engineering construction investment.
According to the detailed description to this utility model specific embodiment below in conjunction with accompanying drawing, those skilled in the art will be more Plus understand of the present utility model above-mentioned and other purposes, advantages and features.
Brief description
