Description
Technical field
The present invention relates to transformer technology field, specially a kind of energy saving transformer.
Background technique
As China's economic continues healthy high speed development, power load is sharply increased, and electricity needs maintains sustained and rapid growth.
4.69 trillion kilowatt hour of national Analyzing Total Electricity Consumption in 2011, increases by 11.7% than last year, consumption demand is still vigorous.It uses per capita
3483 kilowatt hour of electricity increases by 351 kilowatt hours than last year, is more than world average level.
In the power system, the capital equipment that power transformer is transmitted as electric energy, it is a large amount of with the increase of electricity consumption
Increase, running wastage has been an energy loss very serious.Since short trouble is difficult to avoid that in operation, and it is short
The short circuit current that transformer will flow through when road makes transformer by very big mechanical force, destructive shadow may be generated to transformer
It rings, to endanger power grid normal operation.According to transformer theory, the mechanical force and Transformer Short Circuit Impedance square are inversely proportional,
So high-impedance transformer is widely used as the method for improving transformer station high-voltage side bus reliability.At present using more on power grid
Short-circuit impedance three betweens of high-impedance transformer operation windings is respectively as follows: conventional impedance, high pressure-low pressure when the middle pressure of high pressure-is run
High impedance when high impedance, middle pressure-low pressure operation when operation, and impedance when impedance ratio height-middle operation when medium-low operation is big.
High-impedance transformer implementation method traditional at present has: 1) uses magnetic core of transformer-low-voltage coil-high-tension coil
The coil arrangement (splitting the method for high-tension coil) of one-intermediate voltage winding-, two-fuel tank of high-tension coil realizes high resistant resistance
The disadvantages of energy, this method structure is more complicated, transformer load loss is big, manufacturing cost is high；2) uses low-pressure side series reactor
Method realize high resistant anti-performance, similarly there is the defects of transformer size is bigger than normal, structure is complicated and manufacturing cost is high.This is
Because a large amount of three-winding transformer is high and medium voltage full capacity on current power grid, low-voltage coil is only half capacity, therefore, is become
The loss of depressor is to be run with the middle pressure of high pressure-to examine, and traditional transformer comes outside, and high pressure due to high and medium voltage
Coil some in outermost, it is relatively large in diameter when realizing high impedance parameter, increases so as to cause the length under identical the number of turns
Resistance increases, and material utilization amount and running wastage also increase accordingly, in order to can reduce running wastage to standard specified value, often
Often the copper section of coil is amplified to reduce copper wire resistance, also increases the dosage of copper wire in this way.
In conclusion using the method that traditional technology designs such high impedance it is generally existing structure is complicated, manufacturing cost is high,
The disadvantages of environment is unfriendly.
Summary of the invention
To solve above-mentioned deficiency or disadvantage.Technic relization scheme of the invention are as follows: a kind of energy saving transformer, including become
Depressor magnetic core, shield, coil, fuel tank and insulation board.
The beneficial effect is that: since number of coils is identical with conventional transformer, and in high-tension coil and intermediate voltage winding come
Side, therefore coil diameter is relatively small, the length under identical the number of turns is also smaller；When high-tension coil is disposed close to iron core side
When, it need to be configured to shield on iron core surface, with the wedge angle on shielding iron core surface.Reach that running wastage is low, material utilization amount is few, structure is simple
The advantages that single.
Specific embodiment
The technical scheme of the present invention is realized as follows: a kind of energy saving transformer, including magnetic core of transformer, shield, line
Circle, fuel tank and insulation board composition, it is characterised in that the coil includes high-tension coil, intermediate voltage winding, low-voltage coil, any two
Be provided with insulation board among a coil, be followed successively by from magnetic core of transformer to fuel tank magnetic core of transformer, shield, high-tension coil, in
Crimping circle, low-voltage coil, fuel tank.
The magnetic core of transformer is overrided to form for cold-reduced silicon sheet.
The insulation board is the PVC board for wrapping up at least 1 layer insulating paper.
This energy-economic transformer has the advantages that low noise, low energy consumption, structure is simple, manufacturing cost is low etc..
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
