Description
Technical field
The invention belongs to field transformer, more particularly to a kind of small air-immersed transformer of high-voltage bidirectional outlet.
Background technology
At present, existing dry-type transformer, including iron core and coil windings, is wound with coil windings outside iron core, its feature
It is: the line of coil windings is connected by patch panel, patch panel only one of which.For the little dry-type transformer of capacity, by
Shorter in transformator height, the tap outlet of winding and lead phase line, simultaneously in high-pressure side, lead to transformator phase line and tap to be drawn
Line insulation distance is nearer, is difficult to meet required distance, and in lead set, installation difficulty height leads to operative inconvenient, mould
Tool is complicated, and manufacturing cost is high, poor universality, the technical problem such as outward appearance of impact product.
Content of the invention
The invention reside in providing a kind of small air-immersed transformer of high-voltage bidirectional outlet, to solve insulation between phase line and lead
Distance is closely unsatisfactory for very much the problem of charged insulating required distance.
The technical scheme is that a kind of small air-immersed transformer of high-voltage bidirectional outlet, including dry-type transformer originally
Body, coil windings, iron core, described dry-type transformer body cross-section ovalize, the one of described this long axis of body of dry-type transformer
Hold as high-pressure side patch panel, the other end of described this long axis of body of dry-type transformer is low-pressure side patch panel；Described high-pressure side
Patch panel is provided with phase line outlet joint, and described low-pressure side patch panel is provided with tap lead joint, and dry-type transformer is originally
Body is provided with some parting beads being made up of soft magnetic materials, and described dry-type transformer is originally additionally provided with the suction being made up of soft magnetic materials in vitro
Attached layer, is provided with some projections, described raised and parting bead laminating, is arranged with enamel-cover paper outside adsorption layer in described adsorption layer.
During using technique scheme, the small air-immersed transformer coiling group of high-voltage bidirectional outlet is due to employing the present invention
Brand-new technical scheme, compared with prior art, can be effectively increased tap lead and the creep age distance of phase line outlet, reduce and produce
The shelf depreciation problem of product.Dry-type transformer body cross-section ovalize, is not changing creep age distance compared to circular configuration
In the case of more material-saving, floor space is little, and one end of this long axis of body of dry-type transformer is provided with high-pressure side patch panel, the other end
It is provided with low-pressure side patch panel, such setting makes tap lead side layout more reasonable, facilitates operative.
Because parting bead is made by soft magnetic materials with projection, so parting bead can be adsorbed by projection, if outside transformator
A fire broke out by accident, when the intensity of a fire extends to enamel-cover paper, enamel-cover paper is ignited and may result in enamel-cover paper Automatic-falling, thus preventing
The expansion further of the intensity of a fire, but because enamel-cover paper is flexible material, may stick on adsorption layer after being ignited, further,
Parting bead raises rapidly with projecting through magnetic absorption, the ambient temperature around rear transformator on fire, soft magnetism magnetic in high temperature environments
Property can fade away, and leads to the adsorptivity between parting bead and projection to disappear, and adsorption layer then Automatic-falling prevents the intensity of a fire from prolonging further
Stretch, the safety of this transformator is greatly improved.Using this scheme, in coil-winding process, reduce labor intensity, Er Qieji
Improve greatly the fire protecting performance of this low pressure winding.
The present invention has the insulation distance being effectively increased between each lead, increased creep age distance, reduces product office and puts,
There is structure simple, easy to assembly, mould unitizes, highly versatile, low cost of manufacture, and appearance looks elegant is beautiful, and product safety can
By the advantages of.
Further, described high-pressure side patch panel and described low-pressure side patch panel are u shape structure.Such setting adds
Big distance between joint and each lead and phase line, strengthens the structural stability of dry-type transformer.
Further, described phase line outlet joint and described tap lead joint are brazed joint.Brazed joint is for electricity
Stream has good conduction, greatly reinforces service efficiency.
Further, described brazed joint inwall is provided with screw thread.Improve the bonding strength of each lead and joint it is not easy to take off
Fall.
Further, the lower surface of described low-pressure side patch panel and high-pressure side patch panel is higher than all dry-type transformer body
Lower surface.Such setting can make dry-type transformer when placing, under high-pressure side patch panel and low-pressure side patch panel
End is all above the ground level, and ground formation space, facilitates handss or instrument to probe into, is easily installed and carries.
Further, described tap lead joint is multiple, and described phase line outlet joint is 2.Tap lead joint is multiple
Setting meets the needs of a plurality of leads connection, and phase line outlet joint arranges two, can be very good to distinguish into and out of joint.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description:
Fig. 1 is the top view of the embodiment of the present invention；
Fig. 2 is the low pressure side panel schematic diagram of the embodiment of the present invention；
Fig. 3 is the high-pressure side panel schematic diagram of the embodiment of the present invention.
Specific embodiment
Reference: tap lead joint 1, high-pressure side patch panel 2, dry-type transformer body 3, coil windings 4, low pressure
Side patch panel 5, phase line outlet joint 6, iron core 7, parting bead 8, projection 9, adsorption layer 10.
As shown in Figure 1, Figure 2 and Figure 3, a kind of small air-immersed transformer of high-voltage bidirectional outlet, including dry-type transformer originally
Body 3, iron core 7 and coil windings 4, are wound with coil windings 4 outside iron core 7, dry-type transformer body 3 cross section is oval knot
Structure, one end of its major axis is high-pressure side patch panel 2, and the other end of major axis connects low-pressure side patch panel 5, and high pressure side joint
Line panel 2 and low-pressure side patch panel 5 cross section are all the u shape structures extending out, the u shape structure extending out and be shaped as cylindroid
Dry-type transformer body more agrees with, and phase line outlet joint 6 and tap lead joint 1 are all brazed joints, and brazed joint
Inwall is provided with screw thread, and screw thread can improve bonding strength, makes that lead is difficult for drop-off to cause damage, low-pressure side patch panel 5 and height
