Abstract
The utility model discloses a radial double-splitting foil coil. A first coil-out copper bar and a second coil-out copper bar are both located on the inner side of the coil. A first layer of copper foil is welded on the first coil-out copper bar, a first layer of insulation material is wrapped on the inner side of the first layer of copper foil, a second layer of copper foil is welded on the second coil-out copper bar, and a second layer of insulation material is wrapped on the inner side of a second layer of copper foil. The first layer of copper foil and the second layer of copper foil are arranged at intervals. During winding, the first coil-out copper bar and the first layer of copper foil are simultaneously wound on a winding mold, and when winding to a half turn of the inner diameter of the coil, the second layer of copper foil is placed on the inner side of the first layer of insulation material to be wound simultaneously. The radial double-splitting foil coil is less in magnet leakage at the end, small in axial force during a short circuit and strong in short circuit bearing capability. Turn-to-turn capacitance of the coil is evenly distributed along a winding, thereby increasing stability of the winding on impact overvoltage.
Description
Technical field
The utility model relates to a kind of transformer and uses foil coil, specifically a kind of radial pair of division foil coil.
Background technology
Foil coil is exactly the coil of coil with the Copper Foil coiling; During this coil winding earlier Copper Foil with lift one's head the copper bar firm welding, be fixed on the coiling mould and begin coiling lifting one's head copper bar then, on request the number of turn stipulated of coiling; Cut off Copper Foil, weld tail head copper bar and get final product.Generally adopt this foil coil structure in the transformer industry now.
The electric current of low voltage winding in transformers is bigger usually; If want many parallel connections with wire-wound, in coiling, can produce very big helical angle, brow leakage is big; Vertical direction at coil when transformer is short-circuited can produce very big mechanical force, causes the damage of coil; If use the Copper Foil coiling, the width of Copper Foil equals the height of line segment, and end winding is put down; Brow leakage is few; So the axial force in the time of its short circuit is also little, thereby it is strong to bear short-circuit capacity, the foil coil turn-to-turn capacitance is evenly distributed along winding; Increase the superpotential stability of winding impact, and be convenient to realize the mechanization of winding technique process.
Along with developing rapidly of power industry; The purposes of transformer with split winding is increasing; The difference of transformer with split winding and common transformer is that its low pressure winding splits into the branch road that two rated capacities equate (or not waiting), and the voltage and current of these two branch roads equates (or not waiting).Between these two branch roads (coil) and between two branch roads (coil) and other coils enough electrical strengths are arranged, these two branch roads (coil) can also can move simultaneously in isolated operation.Realize the structural design of this transformer with split winding, can't accomplish with foil coil structure and winding method commonly used now.
Summary of the invention
The purpose of the utility model provides a kind of radial pair of division foil coil, and this end winding leakage field is few, and the axial force in the time of short circuit is also little, thereby it is strong to bear short-circuit capacity; The coil turn-to-turn capacitance is evenly distributed along winding, has increased the superpotential stability of winding impact.
The purpose of the utility model realizes through following technical scheme:
A kind of radial pair of division foil coil is characterized in that: this coil comprises the first outlet copper bar, ground floor Copper Foil, ground floor insulating material, the second outlet copper bar, second layer Copper Foil and second layer insulating material; The said first outlet copper bar and the second outlet copper bar all are positioned at the coil inboard; The ground floor Copper Foil is welded on the first outlet copper bar, and it is inboard that the ground floor insulating material is coated on the ground floor Copper Foil; Second layer Copper Foil is welded on the second outlet copper bar, and it is inboard that second layer insulating material is coated on second layer Copper Foil; Said ground floor Copper Foil and second layer Copper Foil are provided with at interval.
In the utility model, the first outlet copper bar and the second outlet copper bar all are positioned at coil inboard and phase difference of half internal coil diameter girth.The second layer Copper Foil that is coated with second layer insulating material is arranged on the inboard of the ground floor Copper Foil that is coated with the ground floor insulating material.
In the utility model, ground floor Copper Foil and inboard ground floor insulating material thereof and the second layer insulating material of second layer Copper Foil and inboard thereof have constituted two mutually independently, the coil that can isolated operation also can move simultaneously.Between these two coils and between two coils and other coils enough electrical strengths are arranged, these two coils can also can move simultaneously in isolated operation.
The utlity model has following advantage: the end winding leakage field is few, so the axial force its short circuit the time is also little, thereby it is strong to bear short-circuit capacity; The coil turn-to-turn capacitance is evenly distributed along winding, has increased the superpotential stability of winding impact.The utility model winding method is simple, convenient, is convenient to realize the mechanization of winding technique process; Need not increase new equipment and frock, on existing common double-deck paper tinsel formula coil winding machine, just can realize.
