Abstract
The utility model relates to a double-voltage oil-immersed transformer which comprises an oil-immersed transformer provided with an iron core. The double-voltage oil-immersed transformer is characterized in that a K2-K3 section winding and a K4-K5 section winding which have equal leakage magnetic flux induced potential are respectively arranged on the upper axial section and the lower axial section of a window of the iron core; and a K0-K1 section winding is sleeved on the K2-K3 section winding and the K4-K5 section winding. During use, when the three sections of windings are connected in parallel, the double-voltage oil-immersed transformer can operate at a grade of 10kV; and when the double-voltage oil-immersed transformer only needs to operate at a grade of 6kV, all that is needed is to connect the K2-K3 section winding and the K4-K5 section winding in parallel and then connect the K2-K3 section winding and the K4-K5 section winding with a K1-K2 section in series. The serial-parallel exchanging double-voltage oil-immersed transformer provided by the utility model ensures that a connection group of the transformer before and after voltage change has no need to be changed, so as to facilitate model selection and the design of the transformer. The transformer with the structure has the characteristics of investment conservation, simple structure, novelty, steady operation performance, and the like, and is convenient to operate.
Description
Technical field
A kind of pair of voltage oil-immersed type transformer of the utility model design.
Background technology
The electrical network rank that conventional distribution transformer high and low pressure side is connect is unique.Also have to have this situation this is subjected to electricity point that a line powering is arranged, another circuit is standby, or a circuit be interim power supply, and another circuit be to power for a long time, and these two circuits are not electric pressures.Be subjected to the rank of electricity that 10kV and 6kV are arranged such as primary side, this will both can be subjected to electricity from 10kV level electrical network by the changes persuing depressor, also can be subjected to electricity from 6kV level net, and the secondary side output voltage is fixed (supposition 0.4kV).Need two transformers (10/0.4 and 6/0.4) that voltage ratio is different generally speaking.But the investment of two transformers is double, takes up an area of also doublely, and the electric line wiring is very complicated, complicated operation.
Summary of the invention
The purpose of this utility model is to provide a kind of pair of voltage oil-immersed type transformer, this pair voltage oil-immersed type transformer is not only simple in structure, reasonable in design, and help realizing that the connection set of transformer need not to change before and after the voltage transformation, for the type selecting and the design of transformer brought convenience.
The two voltage oil-immersed type transformers of the utility model, comprise oil-immersed type transformer with iron core, it is characterized in that: axial upper and lower half section of described core window is respectively equipped with K2-K3 section winding and the K4-K5 section winding that the leakage flux induced potential equates, is arranged with K0-K1 section winding at described K2-K3 section winding and K4-K5 section winding outside.
In use, when three sections windings in series, can run to the 10kV grade; And need only when moving the 6kV grade, K2-K3 section and K4-K5 parallel connection, get final product with K1-K2 section series connection, two voltage oil-immersed type transformers of the utility model serial to parallel conversion make the connection set of voltage transformation front and back transformer need not variation again, for the type selecting and the design of transformer brought convenience.Characteristics such as the transformer of this structure has reduced investment, and is simple in structure, novel, easy to operate, and runnability is stable.

Embodiment
The two voltage oil-immersed type transformers of the utility model, comprise oil-immersed type transformer 2 with iron core 1, axial upper and lower half section of iron core 1 window is respectively equipped with K2-K3 section winding 3 and the K4-K5 section winding 4 that the leakage flux induced potential equates, is arranged with K0-K1 section winding 5 at K2-K3 section winding and K4-K5 section winding outside.
K0-K1 section winding 5, K2-K3 section winding 3 and K4-K5 section winding 4 are respectively equipped with lead-out wire.
This scheme adopts the inner serial parallel conversion of high pressure winding, as shown in Figure 1, 2, 3, when the lead-out wire of three sections windings is connected successively, can run to the 10kV grade; And need only when moving the 6kV grade, with the lead-out wire parallel connection of K2-K3 section and K4-K5 section winding, the lead-out wire series connection with K1-K2 section winding gets final product again.
Two voltage oil-immersed type transformer external structures of the utility model serial to parallel conversion are identical with common transformer, only taked particular processing on the machine body structure of fuel tank internal.As shown in Figure 1, 2, 3, K2-K3 section and K4-K5 section axial distribution lower semisection on window unshakable in one's determination.The selected wire gauge of two sub-windings is identical, equal turn numbers, the width of cloth be to consistent size, axial location and reactance height center symmetry.The electromotive force that has guaranteed two sub-winding leakage flux inductions like this equates that parallel branch respectively flows through the operating current of half, has eliminated circulating current.The K0-K1 section is enclosed within this outside of two sections.
Two voltage oil-immersed type transformer voltage regulating modes of the utility model serial to parallel conversion not only are fit to the transformer of D connection, also are suitable for the transformer of Y connection, and the connection set of transformer need not to change before and after the voltage transformation simultaneously, for the type selecting and the design of transformer brought convenience.Characteristics such as the transformer of this structure has reduced investment, and is simple in structure, novel, easy to operate, and runnability is stable.
