Description
Technical field
The utility model is related to plateau large-scale mine power supply and distribution fields, especially a kind of to be suitable for plateau type 35kV double back framves
" T " the binding structure on ceases to be busy road.
Background technology
In the large-scale mine of plateau, the electrical equipment voltage class used is high（10kV or 35kV）, power is big, quantity is more,
And power load grade is high, need to use dual power supply, to meet power load safely by the requirement of property, therefore frequently with double-bus
The 35kV substations of segmentation carry out equipment power supply.Therefore, the rational delivery to each 35kV substations power supply and guarantee 35kV are aerial
The safe and stable operation of transmission line of electricity is particularly important；And since power supply area is not concentrated inside mine, multiple 35kV need to be set
Substation, therefore, mine in-line power power to end substation frequently with a double back mains supply line, and intermediate substation is then
By from mains supply line " T " mode of connecing power.
Domestic 35kV Double-loop overheads road " T " connects mode at present, generally uses " T " to connect tower and realizes, and existing double back
Road " T " connects tower and only has 3560FGU drum type disagreements tower a kind of, is only applicable to 1000 meters of height above sea level or less area, cannot be satisfied 1000 meters
To the 35kV overhead transmission line demands of 4000 meters of height above sea level.
《66kv and following overhead power line design specification》It is provided in GB50061-2010 tables 7.0.6：35kV double back framves
The conducting wire minimum spacing of ceases to be busy road different circuit is 3 meters, and after being corrected by 4000 meters of height above sea level place High aititude correction factor, minimum
Spacing is 4.8 meters.
Invention content
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, 1000 can be met by providing one kind
Rice to 4000 meters of height above sea level 35kV overhead transmission line demands " T " binding structure.
In order to solve the above technical problems, technical solution used by the utility model is：One kind being suitable for plateau type 35kV
" T " binding structure of double back overhead transmission line, including " T " connect tower, the first base steel tower and the second base in body frame sky supply line
Steel tower, and connect the third base steel tower on place's overhead transmission line positioned at " T "；The first base steel tower mains supply line circuit A passes through
" T " connects left horizontal stretcher wire jumper under tower and connects right horizontal stretcher under tower to " T ", then is connected to the third base steel tower, then mains supply line circuit A
It is connect under tower after left horizontal stretcher wire jumper through " T ", then the second base steel tower is connected to along mains supply line direction；The first base steel tower master
Supply line circuit B connects right horizontal stretcher wire jumper on tower by " T " and then passes through " T " to the third base steel tower and connect the upper right cross of tower
After carrying on a shoulder pole wire jumper, then along mains supply line direction it is connected to the second base steel tower.
It is the steel tower in national standard drawings that " T ", which connects tower tower,：1H3.
The vertical interval of the circuit B lower wires and conducting wire on the A of circuit is 4.8 meters.
In the utility model, mains supply line direction refers to：Tower 1--- " T " connects tower --- tower 2.
Compared with prior art, it is had the beneficial effect that possessed by the utility model：The structure of the utility model can make back
Road B lower wires and the vertical interval of conducting wire on the A of circuit reach 4.8 meters, can meet the 35kV double backs of 1000 meters to 4000 meters height above sea level
Minimum spacing requirement between different circuit conducting wire when overhead transmission line " T " connects.
Description of the drawings
Fig. 1 is the utility model embodiment " T " binding composition；
Fig. 2 is the utility model embodiment circuit A and circuit B wiring diagrams.
Specific implementation mode
As shown in Figure 1, the utility model uses four circuit tower of a base to connect tower as " T ", tower is state's pylom：1H3.
Connecing tower in body frame sky supply line is：Tower 1（First connects tower）, " T " connect tower, tower 2（Second connects tower）；" T " connects place's frame
Ceases to be busy road connects tower and is：Tower 3（Third connects tower）；" tower 1 " circuit A meets " T " and connects left horizontal stretcher under tower, and circuit B meets " T " and connects the upper right cross of tower
Load.
As shown in Fig. 2, circuit A is by cross-arm jumper, left horizontal stretcher wire jumper is connect under tower to lower right horizontal stretcher from " T ", then connect
To " tower 3 ", realize that circuit A " T " connects, circuit A mains supply lines after wire jumper by continuing along former line direction（That is tower 1--- " T "
Connect tower --- tower 2）To " tower 2 "；Circuit B is directly connected to " tower 3 " by cross-arm wire jumper by upper right horizontal stretcher, realizes that circuit B " T " connects,
Circuit B mains supply lines after wire jumper by continuing along former line direction（I.e. tower 1--- " T " connects tower --- tower 2）To " tower 2 "；Thus
It realizes overhead transmission line double loop " T connects ".
The vertical interval of circuit up and down of 1H3 towers is 4.8 meters, this mode makes the vertical of the upper conducting wire of circuit B lower wires and circuit A
Straight spacing can reach 4.8 meters, can meet different circuit when the 35kV double backs overhead transmission lines " T " of 1000 meters to 4000 meters height above sea level connects and lead
Minimum spacing requirement between line.
