Abstract
The utility model discloses a winding arrangement structure with a balanced transformer. The winding arrangement structure comprises an iron core in an oil tank of the transformer, a balance winding, a low-voltage winding, a high-voltage winding and a voltage regulating winding of the high-voltage winding are arranged outside the iron core, the low-voltage winding and the high-voltage winding are in Y-connection, the balance winding is in triangular connection, and the head and the tail of each winding are connected to a sleeve to be led out in an end outgoing mode. The winding arrangement structure is characterized in that the arrangement sequence of the windings outside the iron core from inside to outside is from the low-voltage winding to the high-voltage winding to the high-voltage regulating winding to the balance winding.
Description
Technical field
The present invention relates to a kind of winding arrangement architecture, be applicable to various big capacity AC and DC transformers, arc furnace transformer etc. with balance pattern transformer.
Background technology
The high voltage large capcity that connects for present employing YY (110kV and above, 40MVA and more than) two winding transformer need be provided with the balance winding, and promptly the connection set of transformer is YNyn0+d, and low pressure winding and high pressure winding are that Y connects, and the balance winding is that △ connects.
Tradition winding arrangement architecture is: iron core-balance winding-low pressure winding-high pressure winding-high pressure pressure regulation winding, when transformer capacity was big, high pressure adopted the middle part outlet structure.Along with the raising of customer requirements, product capacity increases, and as continuing that the balance winding is built-in, then the core-diameter of transformer, hauled weight, transportation clearance and material cost will increase a lot, influence the transportation of transformer.
Summary of the invention
The purpose of this utility model is to provide a kind of winding arrangement architecture with balance pattern transformer, when performance requirements such as satisfied insulation, impedance, can effectively dwindle volume of transformer, economical with materials cost, reduce the diameter of the winding of bringing onto load operation, improve the zero load and the load performance of transformer, satisfy three-phase integrated high-power transformer movement requirement.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of winding arrangement architecture with balance pattern transformer, comprise the iron core that is arranged in the oil tank of transformer, arranged outside unshakable in one's determination has balance winding, low pressure winding, high pressure winding and pressure regulation winding thereof, described low pressure winding and high pressure winding are that Y connects, the balance winding is that △ connects, each winding first and last end adopts end outlet method to be connected to sleeve pipe and draws, and it is characterized in that, described each winding is putting in order and be low pressure winding-high pressure winding-high pressure pressure regulation winding-balance winding from inside to outside in the outside unshakable in one's determination.
The utility model is arranged on inboard structure with traditional structure balance winding and compares, and has the following advantages:
1. core-diameter reduces, and the product no-load performance improves.
2. the diameter of the winding of bringing onto load operation reduces, and the product load performance improves.
3. volume reduces, and hauled weight alleviates, and helps the transportation of transformer.
4. economical with materials can reduce the cost of transformer.
Description of drawings
Fig. 1 is a winding arrangement architecture schematic diagram of the present invention.Among the figure: 1 is unshakable in one's determination; 2 is the low pressure winding; 3 is the high pressure winding; 4 is high pressure pressure regulation winding; 5 is the balance winding.
Fig. 2 is a winding connection schematic diagram of the present invention.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1: a kind of Transformer Winding arrangement architecture with the balance winding, comprise a plurality of windings that are arranged on 1 outside unshakable in one's determination in the oil tank of transformer, in this structure, employing is arranged on the mode in the outside with balance winding 5, and each winding is putting in order and be low pressure winding 2-high pressure winding 3-high pressure pressure regulation winding 4-balance winding 5 from the inside to the outside in 1 outside unshakable in one's determination.
Referring to Fig. 2, a is a low pressure winding line end; A1 is a balance winding line end; A is a high pressure winding line end; X is a low pressure winding end; X1 is a balance winding end; X is a high pressure winding end; K is a tap changer, is connected to corresponding sleeve pipe after the requirement connection of each winding first and last end by connection set and draws.
The utility model adopts the balance winding is arranged on outermost structure unshakable in one's determination, has compact conformation, superior performance, and hauled weight is light, and cost is low, and the advantages such as floor space is little are installed, and has reduced the investment cost that power equipment is built.
