Technical field
The utility model is related to transformer technology fields more particularly to a kind of resistance to shorting to consolidate rope copper foil windings.
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
（Or magnetic core）In just generate exchange flux, make to induce voltage in secondary coil（Or electric current）.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 coil generally comprises low-voltage coil and high-tension coil, which is sleeved on outside low-voltage coil, transformer
