Cross-arm, middle cross-arm and lower cross-arm Wei not be gone up, and it is from top to bottom arranged vertically, and 200kV wires cross-arm is located at 500kV wire cross-arms
Lower section；Wherein 500kV wires cross-arm tail end is downward-sloping along bearing of trend, constructs in wild goose wing, and the insulator of 500kV wires
Go here and there as V-type insulator chain, one end of the V-type insulator chain is articulated in the downward-sloping tail end of wild goose wing construction cross-arm, the other end
Then hanger is being located on the tower body of same horizontal line with the tail end.
500kV wires are arranged in respectively on three cross-arms arranged vertically up and down by three-phase, and three cross-arms are arranged in parallel, often
Individual cross-arm is each perpendicular to tower body axis, and now cross-arm extends to the left and right directions of tower body, and the tail end of cross-arm then prolongs along this
The direction stretched is downward-sloping, and thus whole cross-arm is just in a kind of structure form of wild goose wing.On the one hand, cross-arm tail end is downward-sloping
In a kind of form for slightly reclaiming, compare conventional V string cross-arms and reduce certain length；On the other hand, due to inclined tail
End is less than in height cross-arm body, therefore the V strings for mounting also corresponding adjustment downwards, has one end to be articulated on tower body, thus just
Reduce the stress of cross-arm, although the height of V strings is lowered, but the center of 500kV wires is constant, therefore the length also phase of V strings
Should reduce, thereby reduce body cost, reduce line corridor width, reduce construction cost.
The utility model can further be specially：
A pair of earth wire supports are also included, the top of the side of upper cross-arm two being symmetrically distributed in 500kV wire cross-arms is in
Goat's horn is constructed, and is fixedly connected with upper cross-arm.
On the premise of electric insulation cooperation and lightning Protection Design requirement is met, earth wire support is arranged on the cross-arm of upper strata,
Structural system Path of Force Transfer becomes apparent from directly, relative to the independent pylon of traditional earth wire support, effectively reduces ground wire lotus
The action effect of load, and tower material is saved, reduce the height of earth wire support.
200kV wires cross-arm is bilayer, and upper strata cross-arm installs two loop line roads, and lower floor's cross-arm then installs a loop line road；200kV
The insulator chain of wire is V-type insulator chain.
Thus, 200kV wires are double-deck inverted triangle arrangement, and using V-type string, with traditional 3 layers of cross-arm phase arranged vertically
Than, one layer of cross-arm is reduced, tower height is reduced, reduce tower body body cost.
In sum, the utility model provides a kind of loop steel tube tower of wild goose wing mixed pressure four, the insulation of 500kV wires V-type
Substring arranges that 500kV wires cross-arm adopts wild goose wing, compares conventional V strings cross-arm, it is possible to reduce cross-arm length and insulator chain
Length, reduces body cost, and good looking appearance；500kV wire V-types insulator chain arrangement, can reduce width of corridor about 30%,
Corridor congested area can substantially reduce housing demolition amount, and economic and social profit is obvious.Earth wire support and 500kV topping wires
Upper cross-arm is shared, the height of earth wire support is reduced；The 220kV loops of low-voltage are arranged by del, whole tower is reduced
Highly.
