Technical field
The utility model is related to transformer technology field more particularly to a kind of 10kV dry-type transformers new coil structures.
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 generated 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 there are two or more than two 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 is exactly a kind of to 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：As transformer primary side application alternating voltage U1, the electricity of first winding is flowed through
It flows for I1, then the electric current can generate alternating flux in the core, make first winding and secondary winding that electromagnetic connection occur, according to electricity
Magnetic induction principle, alternating flux pass through the two windings that will induce electromotive force, size and umber of turn and main flux
Maximum value it is directly proportional, 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 variation of voltage.But traditional transformer loop construction is complicated, and assembling is cumbersome, and heat dissipation is not
Good, volume is larger.
