Abstract
The utility model discloses a transformer of improved structure, relating to the technical field of transformers. The transformer comprises a framework, and an iron core assembly and a conducting coil which are arranged on the framework. The conducting coil is wound by strip wires. In the transformer of improved structure, the existing conducting coil wound by thread-like wires is replaced by the conducting coil wound by strip wires. As the cross section area of the strip wires is much bigger than that of the thread-like wires, the resistance of the conducting coil is largely reduced, heat produced by the conducting coil is largely reduced, heat losses are reduced, and transformer efficiency is improved. Besides, the cross section area of the strip wires is much bigger than that of the thread-like wires, the rated load capable of being bore by the transformer is largely improved, and transformer damage or failure risks caused by too large transformer load are largely reduced.
Description
Technical field
The utility model relates to the transformer technology field, refers in particular to a kind of structural improvement type transformer.
Background technology
Transformer is a kind of electric device very commonly used, and the basic pattern of transformer comprises that two groups are wound with coil of conductive wire, and claims to lump together in the inductance mode each other.When an alternating current with a certain given frequency flows in one of them group coil, in another group coil, will induce alternating voltage with same frequency.The function of transformer mainly contains: voltage transformation, current transformation, impedance conversion, voltage stabilizing (magnetic saturation transformer) etc.
And in the practice of transformer, after the elementary winding energising of transformer, the magnetic flux that coil produced flows at iron core, because iron core itself also is a conductor, will induced potential on perpendicular to the plane of the magnetic line of force, this electromotive force forms the closed-loop path and produces electric current on the section of iron core, so be called " eddy current " as a vortex.This " eddy current " increases the loss of transformer, and makes the iron core heating of transformer, and the temperature rise of transformer increases.Generally the loss that is produced by " eddy current " is called " iron loss ".In addition, the coiling transformer need be with a large amount of copper conductors, these copper conductors exist resistance, and this resistance can consume certain power when electric current flow through, and this part loss often becomes heat and consumes, and we claim this loss to be " copper loss ".So the temperature rise of transformer is mainly produced by iron loss and copper loss, because transformer exists iron loss and copper loss, so its power output is forever less than input power.When rated power, the power output of transformer and the ratio of input power are called the efficient of transformer.Existing transformer all adopts copper wire to make coil, and the copper wire of such coil is thin, the number of turn is many and cause the resistance of copper conductor bigger, thereby the efficient of transformer is very low, even is lower than 75%.In addition, because the coil copper wire is thinner, the load that causes transformer to bear is very limited, and this also is a big defective of existing transformer.
Summary of the invention
The technical problems to be solved in the utility model provides the structural improvement type transformer that a kind of resistance is low, efficient is high.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: structural improvement type transformer comprises skeleton, is arranged at the core assembly of skeleton and is arranged at the conductive coil of skeleton that described conductive coil is formed by the strip conductor coiling.
Wherein, the cross section of described strip conductor is " one " font.
Wherein, described skeleton is provided with baffle plate.
Wherein, described baffle plate is offered wired hole or wire casing.
Wherein, described skeleton is provided with keyset, and keyset is provided with binding post, and binding post is electrically connected with described strip conductor.
Wherein, described core assembly comprises two opposed iron cores, and this iron core is one-body molded.
The beneficial effects of the utility model are: the utility model provides a kind of structural improvement type transformer, comprises skeleton, is arranged at the core assembly of skeleton and is arranged at the conductive coil of skeleton, and described conductive coil is formed by the strip conductor coiling.The conductive coil that structural improvement type transformer described in the utility model uses adopts strip conductor to come coiling, replace the thread lead of existing usefulness to come the conductive coil of coiling, because strip conductor is more much bigger than the sectional area of thread lead, make the resistance of conductive coil reduce greatly, thereby significantly reduced the heat that conductive coil produces, reduce scattering and disappearing of heat, improved the efficient of transformer.In addition, because strip conductor is more much bigger than the sectional area of thread lead, the nominal load that transformer can bear has also improved a lot, thereby greatly reduces transformer causes transformer to damage or lost efficacy because of load is excessive risk.
