Description
Technical Field
The utility model relates to a bevel edge type coil lead wire row.
Background
The foil coil is formed by winding one wire or a plurality of wires in parallel, and is one type of layered coil. Unlike cylindrical coils are: the lead wire of the foil coil is thin and wide copper foil or aluminum foil, only has 1 turn in the axial direction, has a plurality of turns in the radial direction, and has an axial oil gap after being wound for a plurality of turns. The structure is mainly used for low-voltage and small-capacity transformers.
The foil coil is mainly used for medium and small transformers with the capacity less than 2000 kVA. The foil coil has the advantages that: the mechanical strength is good, the deformation is not easy, and the short-circuit force can be born; the electrical strength is good, and the impulse gradient voltage is uniformly distributed; is convenient for winding.
Foil windings are suitable for low voltage (hundreds of volts), high current (hundreds of amperes to thousands of amperes) windings, and are commonly used as secondary windings for distribution transformers. The foil type transformer adopts high-conductivity copper foil or aluminum foil as a conductive material, wherein the thickness of the copper foil or aluminum foil is about 0.1-2.5 mm, and each layer of the wire foil plate is wound with one turn. Insulating paper is lined between the conductive foils, the thickness is 0.05-0.12 mm, and diamond-shaped dispensing cable paper is generally adopted. Since the conductive foil may have metal dust on the surface and the insulating paper may have small pinholes, a high-strength insulating paper should be used as interlayer insulation.
The head and the tail of the conductive foil plate are welded with conductive bars (cold pressing connection by cold pressing pliers is also adopted) to be used as outgoing lines of windings. The winding direction of the foil winding specifies: the winding advancing direction of the foil plate is anticlockwise, namely left winding direction, as seen from the conducting bar end of the winding outgoing line; the winding advancing direction of the foil plate is clockwise, namely right winding direction. Depending on the structure of the foil winder and the relative position of the person to the machine, this should be: the person winds the winding machine, and the leading-out end of the conducting bar points to the right and turns to the left; points to the left and is the right winding direction.
The foil winding is wound by a common foil winding machine, and the operation is relatively simple. The operation procedure of the foil winding machine is carried out.
The foil winding can also be wound by two metal foil plates in parallel or overlapped, and when the foil winding is wound in an overlapped mode, no transposition is performed. Two metal foil plates are overlapped together and welded on the conducting bars; when the metal foil sheets are wound side by side, the gap between the two metal foil sheets cannot be larger than 1mm, and cannot be overlapped, and the gap can be controlled by braking of the edge adjusting device.
Foil winding machines offer higher productivity and product quality due to their higher degree of automation, foil coils have now been widely used in various large, medium and small transformers. The conventional phase lead-out row for the foil coil comprises a winding row phase lead-out row and a ending row phase lead-out row, and is usually a straight conducting row during manufacturing, and referring to a power transformer manual, when the current density of a lead wire meets the design requirement, the contact area is 3-5 times of the cross section of a small lead wire, in other words, the cross section of the small lead wire can be optimized to be smaller than the contact area, so that the original production is carried out by welding the whole straight conducting row and the conducting foil, and the requirement of saving the production material of the transformer is not met, and the cost is high.
