Description
Technical field
It is the magnetic core of transformer of a kind of high efficiency, low cost the present invention relates to the energy, electric power, electronic field.
Background technique
Magnetic core: magnetic core refers to a kind of sintering magnetic metal oxide being made of various iron oxide mixtures.For example, manganese-
Zn ferrite and nickel-zinc ferrite are typical magnetic core array materials.Manganese-zinc ferrite has high magnetic permeability and high magnetic flux density
Feature, and there is more low-loss characteristic.Nickel-zinc ferrite has high unit area impedance, less than spies such as several hundred low magnetic permeabilities
Property.Current magnetic core is not appropriate for a transformer and exports multiple independent current sources outputs for single design of transformer
Situation, for this purpose, the present invention devises the efficient magnetic core of completely new shared primary coil.
The present invention saves primary wire using the mode for sharing primary coil, and primary coil is located at secondary wire
Circle is intermediate, can accomplish leakage field minimum, efficiency highest, and coiling, installation, easy to maintain.
Summary of the invention
The object of the present invention is to provide the shared primary coil of a kind of high efficiency, low cost, multi-source output efficient magnetic
Core.
A kind of shared efficient magnetic core of primary coil type, principle are that the primary coil that multiple output voltage sources are shared is set
Among secondary coil, the magnetic field for allowing primary coil to generate is changed into the electric field energy of secondary coil as far as possible, due to primary line
Circle is surrounded by secondary coil magnetic core, can accomplish that efficiency highest, cost are minimum through possible reduction leakage field.
The present invention adopts the following technical solutions to realize.
According to a kind of above-mentioned shared efficient magnetic core principle of primary coil type, a kind of shared efficient magnetic core of primary coil type is by justifying
Cartridge type primary coil magnetic core, cylindrical type secondary coil magnetic core, and be provided with the collar plate shape of magnetic core mounting hole or more coreplane and constitute；
Wherein the primary coil magnetic core mounting hole up and down on coreplane is located at the centre of magnetic core coil magnetic core mounting hole, primary coil magnetic
After core, secondary coil magnetic core are mounted on coreplane up and down, secondary coil magnetic core can be evenly distributed with and be looped around around primary coil magnetic core.
Preferably, the primary coil magnetic core is cylinder type, may be implemented preferably to radiate.
Preferably, the cross section of the primary coil magnetic core should be greater than the gross area of primary coil magnetic core.
Preferably, a little heat release holes can be suitably opened on coreplane above and below the collar plate shape, facilitates outlet and heat dissipation.
Preferably, primary, the secondary coil core length should be less than the diameter or width of upper and lower coreplane.
Preferably, the primary, secondary coil magnetic core, upper and lower coreplane are all round, and thickness is greater than secondary magnetic core half
Diameter.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention.
Fig. 2 is upper coreplane main view of the invention.
Specific embodiment
Principle according to the present invention, a kind of shared efficient magnetic core example of primary coil type are as follows:
Example 1
As shown in Fig. 1, a kind of shared efficient magnetic core of primary coil type, by upper coreplane 1, primary magnetic core 2, secondary magnetic core 3, under
Coreplane 5 forms, wherein being provided with outlet hole 4 on upper coreplane 1 or lower coreplane 5.Wherein coreplane is collar plate shape up and down,
Center is provided with the mounting hole of primary magnetic core 2, is provided with 3 mounting hole of secondary magnetic core around primary magnetic core surrounding.In assembly, only
The coil being wound on I-shaped plastic processing frame need to be covered on magnetic core, then fill upper and lower coreplane, gum magnetic core and coreplane down
Contact surface.
The foregoing describe basic principles and main features of the invention and advantages of the present invention.The technical staff of the industry answers
The understanding, the present invention is not limited to the above embodiments, and the above embodiments and description only describe of the invention former
A kind of applicable cases of reason only change component structure, quantity, shape, material without departing from the principle of the present invention
Matter, mounting means, size, the parameters such as move mode, these changes and improvements belong to the scope of the present invention.
