The body structure comprises an iron core, and a low-voltage coil, a medium-voltage coil and a high-voltage coil which are arranged from inside to outside. The body structure is characterized in that a high-voltage voltage regulating coil and a medium-voltage voltage regulating coil are arranged outside the high-voltage coil and wound on the same paper cylinder to form a whole, wherein the medium-voltage voltage regulating coil is arranged in the middle of the paper cylinder, and the high-voltage voltage regulating coil is divided into two parts which are respectively positioned at the two ends of the medium-voltage voltage regulating coil. The body structure has the advantages that the material and energy saving effect is remarkable, the heat radiation performance is good, and the loss is low; the noise is low, the integral volume of the transformer is reduced, the production and the manufacture are convenient, the rated value of the impedance voltage is more accurate, the mechanical strength is good, the dynamic stability and the thermal stability are high, and the safety factor is high.
Description
Technical field
The utility model belongs to the power transformer that is applied to the high voltage power transmission and transforming system, particularly a kind of 66KV and 110KV three winding on-load voltage regulation and reduction transformer machine body structures.
Background technology
The three winding power transformers that use in the electric power system at present are more and more, three winding pressure regulation step-down transformers mainly are after a kind of high tension voltage input, respectively with other two kinds of voltages output, can use for two kinds of line voltage distributions simultaneously, its machine body structure is arranged as: iron core-low-voltage coil-middle pressure voltage regulation coil, intermediate voltage winding, high-tension coil, high pressure voltage regulation coil.This machine body structure is arranged, the middle voltage regulation coil of pressing comes between intermediate voltage winding and the high-tension coil, because middle pressure voltage regulation coil has the tap lead-out wire, distance is wayward between middle pressure voltage regulation coil and the high-tension coil, press voltage regulation coil to divide wiring and the discharge of high-tension coil head end in causing easily, cause accident.And the manufacturability of product is bad, and coil quantity is many, volume is big, and coil diameter is big, and the lead consumption is many, Heavy Weight; Heat dispersion is bad simultaneously, and loss is corresponding more.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of volume little, in light weight, and loss is little, winding perfect heat-dissipating, three safe and reliable winding on-load voltage regulation and reduction transformer machine body structures.
The utility model is achieved in that it comprises iron core, low-voltage coil, intermediate voltage winding and the high-tension coil arranged from the inside to the outside, its special character is: be provided with high pressure voltage regulation coil and middle pressure voltage regulation coil outside high-tension coil, described high pressure voltage regulation coil and middle pressure voltage regulation coil are wrapped on the same paper web and form an integral body, press voltage regulation coil to be arranged on the paper web middle part wherein, the high pressure voltage regulation coil is divided into two parts and lays respectively at middle two ends of pressing voltage regulation coil.
The utility model and traditional like product comparison have following advantage:
1. the material-saving effect is obvious
Reduced by a voltage regulation coil, made the whole coil diameter little a lot, the weight of lead also reduces thereupon.
2. perfect heat-dissipating, loss is low
Because coil diameter reduces, and place, empty road do not have unnecessary coil, and radiating effect is further improved, and supplementary load loss significantly reduce, and energy loss is little, and energy-saving effect is obvious.
3. noise is low
Because improving coil is to be arranged on the paper web vertically, and support locking by interior outer stay and paper web between the coil, make voltage regulation coil more firm, during motion, electric and magnetic oscillation is less, noise is low, and electric field and Distribution of Magnetic Field are more even.
4. it is convenient to manufacture
Because its special arrangement mode, suit is convenient when manufacturing, and has reduced the suit operation one time.
5. the transformer overall volume reduces
Owing to reduced a coil, the transformer core physical dimension reduced, thereby reduced the volume of integrated transformers.
6. specified impedance voltage value down more is tending towards accurate
Because voltage regulation coil is positioned at the outside, its voltage regulation coil does not all insert in the integrated circuit under specified running status, makes that the impedance voltage value is tending towards accurate under the specified running status of transformer.
7. mechanical strength is good, the dynamic thermal stability height
Whole voltage regulation coil has formed an integral body, and with tighten band and in outer stay evenly lock, and the high pressure voltage regulation coil is placed on two ends, reduced a putting property of office, improved the end electric field, makes dynamic thermal stability improve, and increased the coefficient of safety of product.
