Abstract

The invention relates to a transformer which can increase the output power and reduce the energy loss. A pair of or a plurality of pairs of secondary coils are oppositely installed around, inside and outside a primary coil, and the secondary coils are mutually connected in series. The magnetic flux generated around, inside and outside the primary coil is fully used effectively to exert the maximum efficiency, thereby reducing the loss of the electric energy.

Description

The electromagnetic field multiaspect is utilized transformer

Affiliated technical field

The present invention relates to a kind of transformer that can improve power output minimizing energy loss.

Background technology

At present, known transformer structure is made up of primary coil, secondary coil and iron core.Add an alternating voltage U1 on primary coil, alternating current is just arranged in primary coil, it produces alternating flux in iron core.This alternating flux had both been passed primary coil, also passed secondary coil, all will cause induced electromotive force in former and deputy coil.Closed secondary coil circuit just produces alternating current in secondary coil.In transformer when work,, electric current flows through coil and has produced " copper loss " and magnetic flux flow and cross iron core and produced " iron loss ".Because iron loss and copper loss that transformer exists are more, in addition the electromagnetic field that primary coil produced be present in around primary coil and inside and outside have versatility, and existing transformer has only utilized the one side or the part of primary coil electromagnetic field, rest parts is not utilized fully, being depleted in vain.Therefore, existing transformer has the big big energy-consuming of volume, the deficiency that power output is little.

Summary of the invention

In order to overcome the existing big big energy-consuming of volume of transformer, the deficiency that power output is little the invention provides a kind of transformer, and this transformer has that volume is little, power consumption is few, the advantage that power output is big.

The technical solution adopted for the present invention to solve the technical problems is: at the two ends of primary coil or at the inside and outside of primary coil or around primary coil, install a pair of relatively or install manyly to secondary coil, and secondary coil is connected mutually.Around primary coil, inside and outside electromagnetic field, all effectively utilize because magnetic flux and magnetic hinge increase, power output increases thereupon.Along with increasing of power output, the number of turn of former and deputy coil and the size of iron core can correspondingly reduce, and therefore, have not only improved power output but also have reduced the loss of energy, have saved copper material and steel simultaneously again.

The invention has the beneficial effects as follows, increased power output, improved the utilization of electric energy, reduced the loss of electric energy, reduced the size of coil and iron core, saved copper material and steel.
