Abstract

A kind of mirror image balances isolated power supply transformer, including iron core, primary coil and secondary coil, and the iron core includes frame and the coiling stem being connected with two frame sides of frame;Primary coil and secondary coil are wound on coiling stem, and the direction of winding of primary coil and secondary coil is opposite.Due to using such structure, completely isolated power grid firewire is dangerous;The loss of transformer itself reduces;The silicon steel sheet core magnetic saturation principle for balancing isolated power supply transformer by mirror image to the surge from power grid is eliminated;Harmonic wave interference from power grid and third harmonic interference are effectively isolated and are eliminated when armature winding inputs, harmonic wave interference will not be substantially produced using secondary output winding.

Description

A kind of mirror image balances isolated power supply transformer
Technical field
The present invention relates to a kind of transformer.
Background technology
Currently available technology, a kind of isolated power supply transformer, including iron core, primary coil and secondary coil.There are problem It is:Power quality is poor, gushed from power grid stream, harmonic component interference it is relatively more.
The content of the invention
The purpose of the present invention is:A kind of mirror image balance isolated power supply transformer is provided, it stablizes with power quality, harmonic wave The characteristics of component interference is few.
What the present invention was realized in:A kind of mirror image balances isolated power supply transformer, including iron core, primary coil and secondary Coil, it is characterized in that:The iron core includes frame and the coiling stem being connected with two frame sides of frame;
Primary coil and secondary coil are wound on coiling stem, and the direction of winding of primary coil and secondary coil is opposite.
A kind of mirror image balance isolated power supply transformer, it is characterized in that:The laminate patch coefficient of the iron core is big In 0.95.
A kind of mirror image balance isolated power supply transformer, it is characterized in that:The iron core is inflated annealing Processing.
A kind of present invention mirror image balance isolated power supply transformer, due to using such structure, completely isolated power grid fire Line is dangerous;The loss of transformer itself reduces;The silicon steel of isolated power supply transformer is balanced by mirror image to the surge from power grid Piece iron core magnetic saturation principle is eliminated;To the harmonic wave interference from power grid and third harmonic interference when armature winding is inputted into Row is effectively isolated and eliminates, and harmonic wave interference will not be substantially produced using secondary output winding.
Brief description of the drawings
Fig. 1 is the stereogram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of mirror image balance isolated power supply transformer, including iron core 1, primary coil 2 and secondary coil 3, The iron core 1 includes frame 11 and the coiling stem 12 being connected with two frame sides of frame;
Primary coil 2 and secondary coil 3 are wound on coiling stem 12, the direction of winding of primary coil 2 and secondary coil 3 Conversely.
The laminate patch coefficient of the iron core 1 is more than 0.95.
The iron core 1 is inflated annealing.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that the ordinary skill for this area For personnel, without departing from the principles of the present invention, some improvement and modification can also be made, this is also considered as the present invention's Protection domain.
