Technical field
The present invention relates to transformer technology field more particularly to a kind of low drain sense large capacity high frequency middle high-pressure transformers.
Background technology
With the rapid development of power electronic devices, the Switching Power Supply of large capacity high frequency middle high-pressure has become its development and becomes Gesture, the general structure of this power supply be after lower pressure rectifier after being reverse into high frequency voltage again by high frequency middle high-pressure transformer liter Rectification exports after pressure.More on the market at present is the low pressure height used in power frequency large capacity high-tension transformer, Switching Power Supply Frequency power transformer also has part small-power high frequency high voltage transformer, and frequency is in 80kHz or so.High frequency middle high-pressure transformer be in, It is realized in high voltage power supply in the critical elements and Switching Power Supply of boosting and signal isolation and carries out the important of energy stores and transmission Component, the stability that its quality directly influences the efficiency of power supply and high voltage power supply is run, and it is also relate to its of power supply Its technical indicator and Electro Magnetic Compatibility.
Invention content
In view of this, the object of the present invention is to provide a kind of low drain sense large capacity high frequency middle high-pressure transformer, it is existing to solve There is the deficiency in technology.
In order to achieve the above object, the purpose of the present invention is be achieved through the following technical solutions:
A kind of low drain sense large capacity high frequency middle high-pressure transformer, including iron core, insulation framework, heat dissipation base, fastening are provided Part and high and low pressure coil, the heat dissipation base are set to the bottom of the iron core, and the iron core uses Mn-Zn magnetic cores, it is described it is high, Low-voltage coil is arranged concentric and carries out coil winding using Multi-strand excitation, and the insulation framework is comb teeth-shaped.
Above-mentioned low drain sense large capacity high frequency middle high-pressure transformer, wherein the layer insulation of the high and low pressure coil uses H Grade Kapton insulating materials.
Above-mentioned low drain sense large capacity high frequency middle high-pressure transformer, wherein the insulation framework uses high molecular material system At.
Compared with the prior art, the beneficial effects of the present invention are:
It is stable, ensure the safe and reliable operation of product, can be widely applied to argon arc welding machine, inversion rectification industry, has There is vast market prospect.
Description of the drawings
The attached drawing for constituting the part of the present invention is used to provide further understanding of the present invention, schematic reality of the invention Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings:
Fig. 1 shows the overall schematic of low drain sense large capacity high frequency middle high-pressure transformer of the present invention;
Fig. 2 shows the structural schematic diagrams of low drain sense large capacity high frequency middle high-pressure transformer of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts Embodiment shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase Mutually combination.
With reference to shown in figure 1, Fig. 2, low drain sense large capacity high frequency middle high-pressure transformer of the present invention includes iron core 1, insulation framework 2, heat dissipation base 3, fastener 4 and high and low pressure coil 5, heat dissipation base 3 are set to the bottom of iron core 1, and fastener 4 is clamping plate, is selected The Mn-Zn magnetic cores that magnetic core power is big, magnetic conductivity is high, loss is small, the operation is stable is high select reactance height big as magnetic conductive iron Iron core 1 to reduce the Wen Sheng of iron core 1.In terms of conductor selection, the influence of kelvin effect when fully taking into account high frequency, using multiply Excitation wire carries out coil winding, has not only met dielectric strength requirement, but also can reduce kelvin effect, layer insulation is high using temperature classification H grade Kapton insulating materials, ensure the safe and reliable operation of product.In order to meet the insulating requirements under high-voltage operation state, Using a kind of dielectric constant in wider frequency range, very low, breakdown voltage and retting-flax wastewater require all very high high molecular material Insulation framework 2 is done, tolerating high voltage and coil can be supported.The insulation framework 2 of coil makes comb teeth-shaped, to improve between cake Dielectric strength and retting-flax wastewater.High and low pressure coil 5 is carried out concentric cloth by surge voltage caused by order to reduce transformer leakage inductance It sets, the reactance height difference of coil is controlled within 5mm, ensures the abundant interlinkage of primary and secondary coil, reduces circuit Loss, improves the service efficiency of transformer.The basic parameter of this transformer is as follows:Capacity 50kVA, frequency 150kHz, high-pressure side Voltage 6600V, low-pressure side voltage 400V, three-phase and four-line.
From above-described embodiment as can be seen that advantage of the invention is that:
It is stable, ensure the safe and reliable operation of product, can be widely applied to argon arc welding machine, inversion rectification industry, has There is vast market prospect.
Specific embodiments of the present invention are described in detail above, but the present invention is not restricted to tool described above Body embodiment, is intended only as example.To those skilled in the art, any equivalent modifications and replacement are also all in the present invention Scope among.Therefore, made impartial conversion and modification without departing from the spirit and scope of the invention, should all cover In the scope of the present invention.
