Fig. 1 is that 500kV tri-loop nuclear power extra-high voltages of the present utility model are shown with the structure of tower one preferred embodiment
Intention;
In accompanying drawing, the mark of each parts is as follows: 1, tower body, and 2, column foot, the 3, first loop, 4, second servo loop, 5,
Tertiary circuit, 6, cross-arm, 7, V-type insulator string, 8, pedal.
The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 is that 500kV tri-loop nuclear power extra-high voltages of the present utility model are with the structural representation of tower one preferred embodiment.
The utility model embodiment comprises:
The same tower of a kind of 500kV tri-loop nuclear power extra-high voltage, it comprises: tower body body, warning panel (not sign) and pedal 8, described tower body body comprises tower body 1, column foot 2, the first loop 3, second servo loop 4, tertiary circuit 5, cross-arm 6 and V-type insulator string 7, described the first loop 3 adopts cat head shape, and be arranged on described tower body 1, described second servo loop 4 and described tertiary circuit 5 are vertically installed on described tower body 1 with drum type, described column foot 2 is arranged at the bottom of described tower body 1, described warning panel is arranged on described column foot 2, described pedal 8 is arranged on described tower body 1 and described column foot 2, described cross-arm 6 is arranged at described the first loop 3, on described second servo loop 4 and described tertiary circuit 5, described V-type insulator string 7 is arranged on described cross-arm 6, and the number of plies of described cross-arm is 4 layers.
Because 500kV tri-loop nuclear power extra-high voltages are high with the transmission capacity of tower, so high to the reliability requirement of circuit, shaft tower load is also larger, so the form of cat-head transmission tower has been selected in described the first loop 3, can effectively improve safety and the economy of tower.
Described V-type insulator string 7 can effectively reduce windage yaw angle wire, reduces removal amount.
The design of described the first loop 3, described second servo loop 4, described tertiary circuit 5 and described cross-arm 6, can reduce cost, can effectively reduce width of corridor, reduces the room amount of tearing open, reduces the comprehensive method of investment.
On described tower body body, be provided with spelter coating and anticorrosive paint, iron and steel is easy to be subject to the relative humidity of atmospheric environment, temperature, wind direction, wind speed, corrosive medium, dewfall, the impact of the factors such as dust, thereby generation corrosion, so the utility model adopts the anticorrosion special anticorrosive coating that adds of spelter coating, after steel surface spray zinc anode coating, can prevent the corrosion of electrochemical reaction to iron and steel, its principle is that the current potential of topping (zinc) is than the low negativity that is of parent metal, in electrochemical reaction, as anode, be corroded, iron and steel as negative electrode is protected, because the corrosion resistance of zinc self is stronger, in this way there is good rust-proof effect, and anticorrosive paint can allow spelter coating also avoid corroding, thereby better protect power tower, increase application life.
Described warning panel comprises fluorescent screen or luminous plate, and warning panel also can be arranged on described pedal 8 at any time, so not only can play the effect of insulation, prevent that people from producing during near or formal operation and getting an electric shock in misconnection, and can send light, thus remind people not close easily, in case dangerous.
Described tower body body has adopted limb wide region at the Q420 heavy in section of 220mm-250mm angle steel, because three Loop Steel Tower loads are larger, particularly to large angle tower, even if select Q420L200 * 24 compound section also cannot remit rent force request, the requirement of and safety economical from circuit, the utility model adopts wide 220 and 250 the high strength heavy in section angle steel that reaches of limb, can reduce tower material index 5%-10%, reduce the welding capacity in Tower processing process, improve working (machining) efficiency, there is the advantage of saving Energy Intensity Reduction toxic emission.
The utility model 500kV tri-loop nuclear power extra-high voltages with the beneficial effect of tower are: not only have cost low, effectively improve working (machining) efficiency, also there is environmental protection, safety is attractive in appearance, saves the advantage of Energy Intensity Reduction toxic emission.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
