Part, but design icing contains 15mm in 15mm(in meteorological condition) hereinafter, when route need to (height above sea level be super by high altitude localities
Cross 1000m) Ice Area 20mm, 30mm when, universal design shaft tower is obviously insufficient in terms of anti-ice cover ability, and existing general sets
Meter is unable to satisfy high altitude localities requirement in Insulation Coordination selection, tower head structure arrangement, if using universal design shaft tower, it will
Insufficient live part and shaft tower component space, line flashover and icing is caused to fall the power grid accidents such as bar.
Hubei province be China repeat ice ice damage prone areas, frequent occurrence the transmission line of electricity caused by icing reason therefore
Barrier accident, objective reality require counterweight ice coverage area shaft tower to carry out research and extension use, and 220kV transmission line of electricity is as in power grid
Main grid structure, it is particularly necessary to the development of 220kV transmission line of electricity heavy icing area shaft tower.

The ability of tower receiving icing unbalanced tensile force.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of 220kV transmission line of electricity 20-30mm is heavy
Ice formation single loop tangent tower, including the tower leg, tower body and tower head being arranged from the bottom to top, the tower head is by being connected at the top of tower body
A pair of of lower bent lever, crank arm in a pair for being connect with lower bent lever, be arranged on crank arm on conducting wire cross-arm, be connected to conducting wire cross-arm
On two earth wire supports and the ground wire hanging point composition that is arranged at the top of each earth wire support, the middle part of the tower body is equipped with tabula
Material, tabula material both ends are connected by connecting mainboard with the main material of tower body two sides, are equipped at the middle part of tabula material by connecting subplate
The intersecting therewith oblique material of four sections, the other end of each oblique material are connected in the main material of tower body two sides, in the middle part of each oblique material
Not She You a section auxiliary material be connected laterally in main material and another section auxiliary material it is oblique be connected to connection mainboard on.
The utility model by adopting the above technical scheme, can improve steel tower heavy icing area electrical distance requirement and structure by
Force request improves the ability that steel tower bears icing unbalanced tensile force.
