At present, in the 110kV fraction fission depressor that uses, low pressure winding, high pressure winding, pressure regulation winding all are independent coilings, independent suit, suit inconvenience, electric and bad mechanical strength; The division step-down presses the winding segments number average to adopt the even number section, and the outlet of low pressure two ends is at the outside diameter of winding, and the size that the 110kV fraction is split transformer body is bigger, and cost is than higher.
(3) summary of the invention
The present invention is in order to remedy the defective of prior art, provides a kind of intensity height, volume little, the transformer with split winding that cost is low.
The present invention is achieved through the following technical solutions:
A kind of transformer with split winding, comprise transformer core, the first low pressure winding that is arranged above and below and the second low pressure winding, the first high pressure winding that is arranged above and below and the second high pressure winding, the first pressure regulation winding that is arranged above and below and the second pressure regulation winding, above-mentioned three groups of windings from left to right are arranged in order, two ends up and down at all windings are respectively equipped with top board and bottom plate, be provided with the moulding square ring between top board and the first high pressure winding, it is characterized in that: the described first low pressure winding and the second low pressure winding are wound on the first moulding cardboard cylinder jointly; The first high pressure winding and the second high pressure winding are wound on the second moulding cardboard cylinder jointly; The first pressure regulation winding and the second pressure regulation winding are wound on the 3rd moulding cardboard cylinder jointly.
The described first low pressure winding and the second low pressure winding adopt the continous way structure, and the winding hop count is odd number, and outlet, low pressure two ends all is positioned at the side near the first moulding cardboard cylinder.
Be provided with the core insulation as the common outlet passage of the first high pressure winding and the second high pressure winding between the described first pressure regulation winding and the second pressure regulation winding, described core insulation is to be stay and the insulation system that rivets with insulated rivet between the ring-type that surrounds of two-layer paper web, the two-layer paper web, and the passway of described outlet passage is positioned on the sidewall of described core insulation.
The invention has the beneficial effects as follows:
1, two groups of low pressure windings, two groups of high pressure windings and two groups of pressure regulation windings are wound on respectively on the moulding cardboard cylinder jointly, therefore structure is simple more, arrangement is tight more, suit is convenient, can effectively reduce the volume of transformer with split winding, and improve electric and mechanical strength.
2, the low pressure winding adopts the continous way structure, the winding hop count is odd number, and the outlet of low pressure two ends is all near a side outlet of the first moulding cardboard cylinder, easy to operate and amplified the insulation distance of low pressure winding outlet to the high pressure winding, more safe and reliable, and can effectively reduce the size that the 110kV fraction is split transformer body, the reduction volume of transformer, the consumption that saves material has reduced cost.
