Abstract
The utility model discloses a low magnetic leakage main transformer. Current transformer is first, secondary coupling is good inadequately in order to overcome, and big class of leakage inductance is not enough, the winding comprises the line cake of a plurality of prefabrications, three -layer insulated wire coiling for the primary, and secondary coil falls into a plurality of " line cake " coiling with flat flat line coiling, will insert between the primary around good secondary " line cake ". The utility model discloses mainly used is used in power supply, uninterrupted power source, and domestic appliance control panel etc. It is just, secondary coupling is good, and the magnetic leakage is few, and the leakage inductance is little, and is effectual, handling ease especially, efficiency improves, cost reduction.
Description
Technical field
This utility model relates to a kind of transformator, is specially a kind of low magnetism leakage main transformer.
Background technology
Tightness relation leakage inductance (inductance of leakage field) reaction during the primary and secondary coupling of transformator, leakage inductance reaction is the least better, and the efficiency of leakage inductance hour transformator is high.Existing main transformer, is the most all to use " sandwich " winding, is wound between primary by secondary folder, at the beginning of so can increasing, the coupling between secondary, reduces leakage inductance.But, first, secondary between need to do and insulate, and primary inductance is relatively big, and the coiling number of turns is more, multilamellar to be coiled into, and secondary current is relatively big, and line footpath is the biggest, thus causes winding height big, and primary and secondary coupling is the best.
Utility model content
The purpose of this utility model is aiming at above-mentioned deficiency, it is provided that a kind of low magnetism leakage main transformer, and well, leakage field is few, and leakage inductance is little, effective, especially handling ease in its primary and secondary coupling, and efficiency improves, and cost reduces.
For reaching above-mentioned purpose, the technical solution of the utility model is, this low magnetism leakage main transformer, and including the winding being arranged on iron core, described winding is made up of some prefabricated line cakes.
Described line cake is rolled by monolayer enamel-covered wire and forms.
Described line cake is flat, and each line cake is connected non junction.
Three layer insulation wire coiling used instead by this utility model primary coil, insulate, and can save frame design；Secondary coil flat wire coiling, is divided into multiple " line cake " coiling, inserts between primary coil by the secondary " line cake " wound, and farthest improves the coupling of primary and secondary, leakage inductance being accomplished, minimum, high-frequency effects and withstanding current capability are more preferable；Just, secondary can separate coiling, then assembles, more existing more convenient further around secondary after complete primary；Use design of windowing by all kinds of means, at utmost improve radiating effect.
This utility model is mainly used in being used in power supply unit, uninterrupted power supply (ups) Unity, household electrical appliance panel etc., and well, leakage field is few in its primary and secondary coupling, and leakage inductance is little, effective, especially handling ease, and efficiency improves, and cost reduces.
Accompanying drawing explanation
Fig. 1 is this utility model cross section schematic top plan view.
In figure, 1. iron core, 2. line cake.
Detailed description of the invention
As shown in this figure, this low magnetism leakage main transformer, including the winding being arranged on iron core 1, described winding is made up of some prefabricated line cakes 2, and line cake 2 is rolled by monolayer enamel-covered wire and forms, and line cake 2 is in flat, and each line cake 2 is connected with each other non junction.
The three layer insulation wire coiling of this utility model primary coil, can save frame design；Secondary coil flat wire coiling, is divided into multiple " line cake " coiling, inserts between primary coil by the secondary " line cake " wound, and farthest improves the coupling of primary and secondary, leakage inductance being accomplished, minimum, high-frequency effects and withstanding current capability are more preferable；Just, secondary can separate coiling, then assembles, more existing more convenient further around secondary after complete primary；Use design of windowing by all kinds of means, at utmost improve radiating effect.
