Fig. 2 is a kind of schematic cross-section of the shaft tower 1 of complex pole tower for single pole power distribution station of the invention.
Specific embodiment
In order to preferably understand technical solution of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail:
Referring to Fig. 1, a kind of complex pole tower for single pole power distribution station of the invention, including shaft tower 1, distribution transformer
2 and low-voltage cabinet 3.
Referring to Fig. 2, shaft tower 1 is multilayer hollow circular tube structure, the tube wall of the multilayer hollow circular tube structure is three layers compound
Structure is followed successively by steel pipe layer 11, concrete layer 12 and GFRP layer 13 from inside to outside.Innermost layer is steel pipe layer 11, is had good
Pull resistance can reduce body of rod deformation when bearing bias, and constrain internal cavities shape, and cavity inside accommodates transmission line of electricity, make
Transmission of electricity is arranged inside shaft tower 1,11 inner wall smooth of steel pipe layer, can be effectively reduced height voltage cable in electric pole and installed, transporting
The mechanical wear of crust during row.Concrete layer 12 is sandwiched between on the outside of steel pipe layer 11, concrete layer 12 is using non-reinforced
Plain concrete is main pressure-containing member in tower 1 with good compressive property.It can be generated when single structure concrete compression
Cydariform deformation in this complex pole tower, is externally wrapped in concrete layer 12 to gradually generate crack and is covered with GFRP layer 13,
The GFRP material of GFRP layer 13 has good tensile property along machine direction, constrains coagulation jointly with the steel pipe layer 11 of internal layer
Native interlayer.By ectonexine to the effect of contraction of concrete layer 12, complex pole tower bears axis pressure, the performance of bias is about same specification
2 times of concrete shaft tower.Simultaneously as compound electric pole can realize hand haulage and lifting using hollow structure, it is particularly suitable for old
The region that the big machineries such as Old residential area, mountain area can not go deep into.
Opening up there are two Unilateral-hole 4 one on the other on the side wall of shaft tower 1, the two Unilateral-holes 4 are located at shaft tower
Two sides.Two transmission lines of electricity of the one-in-and-one-out arranged inside shaft tower 1 pass through two Unilateral-holes 4 respectively and draw inside shaft tower 1.
In order to distinguish the transmission line of electricity of inlet wire and appearance mutually, avoids mutually tangling interference between route, be provided just for trace arrangements
Victory is connected with one piece of partition 111 on the inside of steel pipe layer 11, and the inside of shaft tower 1 is separated into two spaces by partition 111, any one
Space corresponds to a Unilateral-hole 4, so that the progress or outlet of transmission line of electricity possess separate space.
The top of shaft tower is arranged in distribution transformer 2, and center of gravity is located at the center of shaft tower 1, and high pressure inlet wire is inside shaft tower
Cabling, and distribution transformer 2 is accessed by the Unilateral-hole 4 of top, the low-pressure line-outgoing of distribution transformer 2 is connect with low-voltage cabinet 3.Match
2 top side detachable of piezoelectric transformer is provided with waterproof enclosure 21, is equipped with high pressure lead-in line joint and low-pressure line-outgoing in waterproof enclosure 21
Connector, high pressure inlet wire and low-pressure line-outgoing pass through high pressure lead-in line joint respectively and low-pressure line-outgoing connector is connect with distribution transformer 2.It is anti-
Manhole cover 21 makes outside without exposed live part, avoids infield surrounding there are when tier building, high-rise article is fallen to
Head cover of transformer causes short circuit or high pressure to scurry into the hidden danger such as low pressure.
Low-voltage cabinet 3 is fixed on the side of shaft tower 1 by anchor ear, ipsilateral with the Unilateral-hole 4 of lower section, the output line of low-voltage cabinet 3
Road is accessed inside shaft tower 1 by the Unilateral-hole 4 of lower section.
The design parameter of complex pole tower for single pole power distribution station of the invention is transformer capacity 200kVA, transformation
Device quality 878kg, low-voltage cabinet quality 50kg, 4 diameter 0.12m of shaft tower Unilateral-hole, shaft tower Unilateral-hole 4 are highly respectively 3m and 4m,
Steel pipe layer outer diameter 300mm internal diameter 295mm in shaft tower multilayered structure, concrete layer outer diameter 350mm internal diameter 300mm, GFRP layer outer diameter
354mm internal diameter 350mm, GFRP layer Young's modulus are along machine direction 24610MPa, vertical fibers direction 12140MPa.
Current shaft tower is all largely steel tower either cement shaft tower, at present carry distribution transformer platform area, usually
Using double rod tower, single-pole tower due to itself there are the problem of, be chiefly used in temporary electricity, rural electricity consumption occasion.Single pole shaft tower is main
There are problems that following both sides: as soon as, single pole shaft tower due to load-bearing capacity deficiency, the power distribution station of slightly larger capacity is unbearable
Weight.Two, single pole power distribution station is installed on the form of electric pole side using transformer, this makes single pole shaft tower unbalance stress, causes
The regional shaft tower having is set the case where electric pole lodging once occurred.Complex pole tower for single pole power distribution station of the invention, thirdly
Layer composite construction has many advantages, such as that light and bearing capacity is strong, so single pole shaft tower can be with the distribute-electricity transformer district of carry larger capacity；
Transformer is changed to top installation from side hanging installation simultaneously, is provided with cable cavern on shaft tower, platform area high pressure inlet wire and low pressure go out
Line cabling from the shaft tower body of rod, and pass through hole access transformer or low-voltage cabinet, head cover of transformer detachable type waterproof enclosure
It covers, high-low pressure casing and connector is kept in capping, low-voltage cabinet is fixed on electric pole side by double embrace hoop, can reduce in this way
Single pole shaft tower the case where falling bar.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
