Description
Technical field
The present invention relates to transformer technology field, more particularly to a kind of oil-immersed type electric transformer radiator.
Background technology
Transformer is to convert alternating voltage, electric current and the device of impedance, when being connected with alternating current in primary coil, iron core
Exchange flux is just produced in (or magnetic core), makes to induce voltage (or electric current) in secondary coil.Transformer is by iron core (or magnetic core)
Formed with coil, coil has two or more windings, wherein connect the winding of power supply primary coil, remaining winding
Secondary coil.In generator, either coil movement by magnetic field or Movement in Magnetic Field by fixed coil, can be in coil
Induced potential, this two kinds of situations, the value of magnetic flux is constant, but has variation with the magnetic flux quantity of coil intersecting chain, this is mutual inductance
The principle answered.Transformer be exactly it is a kind of utilize undesirable mutual electromagnetic inductance effect, voltage of transformation, the device of electric current and impedance.Transformer is main
Carry out work using electromagnetic induction principle.Specifically：When transformer primary side applies alternating voltage U1, the electric current of first winding is flowed through
For I1, then the electric current can produce alternating flux in the core, make first winding and secondary winding that electromagnetic connection occur, according to electromagnetism
Principle of induction, alternating flux will induce electromotive force through the two windings, its size and umber of turn and main flux
Maximum is directly proportional, and the side voltage more than umber of turn is high, and the few side voltage of umber of turn is low, when Circuit Fault on Secondary Transformer is opened
During road, i.e. no-load transformer, one or two terminal voltages are directly proportional to a secondary winding number of turn, i.e. U1/U2=N1/N2, but it is primary with
Secondary frequencies are consistent, so as to fulfill the change of voltage.
But the efficiency of cooling is not fine, once transformer is rapidly heated, it is impossible to fast cooling, inevitably can be to transformer
Work have an impact.
