To be mutually combined.
With reference to shown in figure 1, Fig. 2, the utility model low drain sense Large Copacity high frequency middle high-pressure transformer includes iron core 1, insulation
Skeleton 2, heat dissipation base 3, fastener 4 and high and low pressure coil 5, heat dissipation base 3 are located at the bottom of iron core 1, and fastener 4 is clamping plate,
From the Mn-Zn magnetic cores that magnetic core power is big, magnetic conductivity is high, loss is small, working stability is high as magnetic conductive iron, and it is high from reactance
The big iron core 1 of degree is with the temperature rise of reduction iron core 1.In terms of conductor selection, the influence of kelvin effect when fully taking into account high frequency, use
Multi-strand excitation carries out coil winding, has both met dielectric strength requirement, and and can reduces kelvin effect, and layer insulation is using heat-resisting etc.
The high H level Kapton insulating materials of level, ensure the safe and reliable operation of product.In order to meet that the insulation under high-voltage operation state will
Ask, using the macromolecule that a kind of dielectric constant in wider frequency range is very low, breakdown voltage and retting-flax wastewater requirement are all very high
Material does insulation framework 2, can tolerating high voltage, and can support coil.The insulation framework 2 of coil makes comb teeth-shaped, to improve
Dielectric strength and retting-flax wastewater between cake.In order to reduce surge voltage caused by transformer leakage inductance, high and low pressure coil 5 is carried out together
The heart is arranged, the reactance height difference of coil is controlled within 5mm, ensures the abundant interlinkage of primary and secondary coil, reduces electricity
The loss on road, improve the service efficiency of transformer.The basic parameter of this transformer is as follows：Capacity 50kVA, frequency 150kHz are high
Press 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 present utility model is：
It is stable, ensure the safe and reliable operation of product, can be widely applied to argon arc welding machine, inversion rectification industry, have
There are wide market prospects.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
