Description
Technical field
The utility model belongs to field of electrical equipment, is specifically related to a kind of dry-type transformer.
Background technology
Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, it have a public iron core and with its crosslinked several windings, and locus between them is constant, when some windings receive AC energy from power supply, by inductance magnetisation, the electromagnetic induction principle of the raw electricity of magnetic strength changes voltage, with same frequency in remaining winding, and different voltage transmission AC energy.Transformer can be divided into oil-filled transformer and dry-type transformer by the type of cooling, at present, the low pressure winding of dry-type transformer mostly is copper conductor and forms around finger, it is little that this low-voltage, big current wire have anti-short circuit capability around the coil referred to, ampere-turn is uneven, and radiating effect is poor, replace uneven, the outstanding problems such as supplementary load loss are large, and human weld's quality is unstable, the serious normal operation that have impact on transformer.
Therefore, need a kind of new technical scheme to solve the problem.
