Abstract

The law of magnetic field distribution of dry type half-iron-core reactors is studied by using field-circuit coupling method.Firstly

the self inductance and mutual inductance of the paralleled branch coils for the dry type half-iron core reactor are obtained by way of finite element magnetic field calculation result.Then

the current of the paralleled branch coils excited by sine voltage is obtained by way of phasor.Lastly

an axial symmetrical magnetic field calculation model of the dry type half-iron core reactor is established by way of finite element

the influence of iron on the rule of magnetic field distribution of reactor is analyzed and calculated

which provides theoretical evidence for the design and development of the dry type half-iron core reactor.
