Description

The elliptic low-loss power transformer
Technical field
The utility model relates to power equipment manufacturing technology field, is specifically related to a kind of elliptic low-loss power transformer of the 10kV of being particularly useful for electric pressure.
Background technology
Circular power transformer unshakable in one's determination and winding construction is the traditional structure of China's power transformer always, uses for many years always.Development along with transformer industry, the transformer manufacture level of China improves constantly, from S5 series to S7 series, eliminate S9 and the S11 series of generally using today from S7 series, the power transformer performance improves constantly, to reducing grid loss, improve power consumption efficiency and played important function, also made positive contribution for national economic development.But transformer technology develops into now, further reduce transformer loss on S11 transformer series basis, promotes the transformer self performance, reduces the loss of electric energy to greatest extent, and this has run into bigger difficulty for the transformer manufacturing.Except adopting the more advanced core material of performance, as if having no other way.
The utility model content
Technical problem to be solved in the utility model is: how a kind of elliptic low-loss power transformer is provided, this elliptic low-loss power transformer can make the loss of transformer further be minimized, its performance is further promoted, but also have simple and reasonable, be easy to advantages such as processing, safe and reliable, cheap for manufacturing cost, the little light weight of volume.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of elliptic low-loss power transformer is provided, comprises oil tank of transformer, transformer oil, winding insulation spare, conservator, dehydrating breather, gas relay protector, low-voltage wiring terminal, high-voltage connection terminal, signal thermometer, corrugate fin and transformer oil; Described oil tank of transformer is a sealed construction, and the oil tank of transformer below is provided with the supporting pad pin; Be provided with transformer oil in the described oil tank of transformer, oil tank of transformer is outside equipped with dehydrating breather, gas relay protector, low-voltage wiring terminal, high-voltage connection terminal, signal thermometer and corrugate fin; It is characterized in that: also be provided with the oval winding of oval iron core, fixed clip unshakable in one's determination and three-phase in the described oil tank of transformer; Described oval iron core is made up of A phase core limb, B phase core limb, C phase core limb, lower yoke and upper yoke; The cross section of described A phase core limb, B phase core limb, C phase core limb, lower yoke and upper yoke is ellipsoidal structure; The oval winding of described three-phase is set in A phase core limb, B phase core limb and C mutually on the core limb; Described fixed clip unshakable in one's determination is arranged on oval end unshakable in one's determination and is fixed on the casing of oil tank of transformer.
In sum, elliptic low-loss power transformer provided by the utility model is compared with traditional power transformer and is had the following advantages:
1, effectively reduces the transformer loss level, for the transformer technology development provides a new consumption reduction method.Traditional power transformer structure is circular core limb and circular winding construction, in order to reduce transformer loss, each producer often adopts new better core material to reduce transformer loss, the development of transformer often is subjected to the restriction of material like this, if there is not the lower silicon steel material of monolithic loss to come out, transformer will further reduce the wastage on the original basis and will be extremely difficult thing so.The beneficial effects of the utility model are to be not limited to the performance of core material, start with but reform fully from the transformer self structure fully, reduce transformer loss from the reform fully of structure.If the use that combines with the performance better material of this structure, the raising that the performance that makes transformer is obtained advancing by leaps and bounds.
2, volume of transformer is little, and is in light weight.By the oval structure design, make the magnetic circuit of transformer core shorten, overall weight unshakable in one's determination reduces, and transformer length shortens, and product integral body presents miniaturization and lightness characteristics.The storage of transformer, transportation, lifting, installation etc. are brought great convenience.
3, the electrical network energy loss reduces significantly, and power consumption efficiency increases substantially.Because the superior properties of product of oval structure transformer, the overall product loss reduces significantly, makes the effective rate of utilization of electrical network electric energy increase substantially, and will bring huge benefit for national grid and national economy.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure, this elliptic low-loss power transformer comprises oil tank of transformer 2, transformer oil 18, winding insulation spare, conservator 11, dehydrating breather 12, gas relay protector 13, low-voltage wiring terminal 14, high-voltage connection terminal 15, signal thermometer 16, corrugate fin 17 and transformer oil 18; Described oil tank of transformer 2 is a sealed construction, and oil tank of transformer 2 belows are provided with supporting pad pin 3, and oil tank of transformer 2 belows are provided with pressure relief device; Be provided with transformer oil 18 in the described oil tank of transformer 2, oil tank of transformer 2 is outside equipped with dehydrating breather 12, gas relay protector 13, low-voltage wiring terminal 14, high-voltage connection terminal 15, signal thermometer 16 and corrugate fin 17; It is characterized in that: also be provided with the oval winding 1 of oval iron core 5, fixed clip unshakable in one's determination 4 and three-phase in the described oil tank of transformer 2; Described oval unshakable in one's determination 5 are made up of A phase core limb 7, B phase core limb 8, C phase core limb 10, lower yoke 9 and upper yoke 6; The cross section of described A phase core limb 7, B phase core limb 8, C phase core limb 10, lower yoke 9 and upper yoke 6 is ellipsoidal structure; The oval winding 1 of described three-phase is set in A phase core limb 7, B phase core limb 8 and C mutually on the core limb 10; Described fixed clip unshakable in one's determination 4 is arranged on oval unshakable in one's determination 5 end and is fixed on the casing of oil tank of transformer 2.
The oval winding of the three-phase of this transformer is set with on three oval core limbs of three phase three limb core, and core insulation end circle is inserted at the two ends up and down of coil, and the clamping core clamping 4 then, and clamping consolidation unshakable in one's determination is firm.Welding lead and tap lead are installed the insulated conductor clamping and are gone between surely and tap lead then, and shunting switch is installed.After above-mentioned work is finished, whole device body is sent into the dry humidity discharging of drying room and is handled, last whole device body lifting enters oil tank of transformer 2, by four of four locating pins at the bottom of the transformer tank and fuel tank panels fixedly boatswain chair location and fixture body position, vacuum is injected transformer oil 18 then, sealed transformer fuel tank 2, quiet putting after 24 hours tested.The transformer outside is made of the integral body of a compact main parts such as dehydrating breather 12, gas relay protector 13, high-voltage connection terminal 15, low-voltage wiring terminal 14, signal thermometer 16, corrugate fin 17, conservator 11, pressure relief devices.
