Abstract
An elliptic oil-immersed distribution transformer, which belongs to the transformer and mainly solves the problem of high cost of the common transformer, comprises a columnar iron core, a low-voltage winding and a high-voltage winding wound on the iron core, wherein the cross section of the iron core has an elliptic structure with straight edges on both sides; the low-voltage winding and the high-voltage winding are also designed to be the elliptic structure; the thickness of an insulation layer between the high-voltage winding and the low-voltage winding is designed to be 4 mm on the straight edge section, and 6 mm on the arc-shaped structure section; and coil is made of the oxyacid free copper. The transformer with the above structure has greatly reduced cost, and improved short circuit resistant capacity and electrical strength, thereby prolonging the service life of the transformer.
Description
Technical field
The utility model relates to a kind of transformer, and specifically a kind of iron core is oval-shaped oil immersion-type distribution transformer.
Background technology
In present transformer Electromagnetic Design, no matter be S9 type transformer, or the S11 type product that each transformer production producer designs voluntarily, the iron core that uses all is the cylindrical core of fixing generally, core section is circular, though the iron core good looking appearance of circular cross-section, but consumptive material is many, under the situation of transformer raw material continuous rise, with the circular structure of the Cross section Design of iron core, it will be very many causing the use amount of coil windings, cost is also very high, if iron core is become other shapes with design of Windings, be easy to influence the various performances of transformer, so there is the high problem of cost in common oil immersion-type distribution transformer.
The utility model content
At the existing high problem of oil immersion-type distribution transformer cost, the utility model provides a kind of coil and use cost unshakable in one's determination of both can having reduced, do not influence the oval oil immersion-type distribution transformer of transformer performance again, it is by becoming oval structure with iron core with design of Windings, dispose rational structure then, reduce coil and use amount unshakable in one's determination greatly.
The concrete technical scheme that the utility model adopts is: oval oil immersion-type distribution transformer, comprise that cylindricality is unshakable in one's determination and be wrapped in low pressure winding and high pressure winding on the iron core, described core section is set as the ellipsoidal structure that both sides are straight flange, the ellipsoidal structure that it is straight flange that low pressure winding and high pressure winding are made as with corresponding both sides unshakable in one's determination, by winding is changed over oval structure, can reduce coil and use amount unshakable in one's determination greatly, iron core is even column structure, this design only needs the ellipsoidal structure that both sides are straight flange is arranged in the cross section of iron core, usually the pairing cambered surface of ellipse short shaft is made as and faces directly, be beneficial to use.
The thickness of insulating barrier is made as 4mm at its straight flange structure division between described low pressure winding and the high pressure winding, partly be made as 6mm at its arc-shaped structure, because two coils abut against together, need insulating barrier, so according to research experiment, the thickness of taking the insulating barrier between the high-low pressure winding is made as 4mm and circular arc shaped portion is made as 6mm the best at its straight portion, coil has adopted the cable paper of special insulating material 0.2mm to fill the insulating barrier of straight flange structure division 4mm, and the structure that adds 4mm corrugation oil duct with the 0.2mm cable paper has been filled the insulating barrier of 6mm.
Described winding uses oxygen-free copper wire-wound system, and lead is handled through a series of additional surfaces, more smooth, no burr, the load loss of reduction transformer.
The beneficial effects of the utility model are: this ellipse oil-immersed distributing transformer is by being set as ellipsoidal structure with winding, make transformer on the oxygen-free cupreous use amount reduce greatly, thereby reduced the production cost of transformer, the insulation distance of rational high-low pressure winding is set, improved the anti-short circuit capability and the electrical strength of transformer, performance is more reliable, also increases oval mechanical Strength for Winding simultaneously, and keep lower noise, guaranteed the useful life of transformer.
Description of drawings
Accompanying drawing 1 is the vertical view of the iron core of band winding in the utility model.
The 1st, unshakable in one's determination, the 2nd, low pressure winding, the 3rd, high pressure winding, the 4th, insulating barrier.
Embodiment
As shown in Figure 1, this ellipse oil immersion-type distribution transformer, comprise iron core 1 and the low pressure winding 2 and the high pressure winding 3 that are wrapped on the iron core, 1 cross section unshakable in one's determination is set as the ellipsoidal structure that both sides are straight flange, low pressure winding 2 and high pressure winding 3 also are made as this ellipsoidal structure, what winding used is oxygen-free copper wire-wound system, this elliptical coil has reduced the use amount of copper cash greatly, thereby reduce the cost of transformer, coil uses oxygen-free copper wire-wound system, reduce the load loss of transformer, the thickness of insulating barrier 4 is made as 4mm at its straight flange structure division between low pressure winding 2 and the high pressure winding 3, as A=4mm among the figure, partly be made as 6mm at its arc-shaped structure, as B=6mm among the figure, coil has adopted the cable paper of special insulating material 0.2mm to fill the distance of straight flange structure division 4mm, and the structure that adds 4mm corrugation oil duct with the 0.2mm cable paper has been filled the insulation distance of 6mm.
This ellipse oil-immersed distributing transformer is by being set as ellipsoidal structure with winding, reduced the use amount of lead in the winding greatly, thereby reduced the use cost of transformer, winding uses oxygen-free copper wire-wound system, reduce the load loss of transformer, by rational height winding insulation layer is set, improved the anti-short circuit capability and the electrical strength of transformer, performance is more reliable.
What other contents of not describing adopted is prior art, does not repeat them here.
