HIGH-VOLTAGE TRANSFORMER COMPRISING A FOIL WINDING

摘要

The low-voltage winding of a line transformer consists of a foil winding. In order to tune the line transformer to the third or the fifth harmonic, the coupling factor is adjusted by sliding the highvoltage winding with respect to the low-voltage winding. The length of the leg of the core whereabout the low-voltage winding and the highvoltage winding are arranged substantially exceeds thewidth of the lowvoltage winding. The high-voltage winding can be partly slid off the low-voltage winding, with the result that the coupling factor is reduced.
