摘要： A partial discharge test power supply system for an extra high voltage transformer comprises: an electric motor (1); an intermediate frequency generator (2) driven by the electric motor and outputting an intermediate frequency voltage; a middle transformer (9) receiving the intermediate frequency voltage and outputting a test voltage to be applied to a test sample (11) by a generator outlet (5); a low-voltage compensating reactor (8) connected between the intermediate frequency generator and the middle transformer; a high-voltage compensating reactor (10) connected between the middle transformer and the sample; wherein the electric motor and the intermediate frequency generator are arranged in a metal housing (100). The system also includes the following filters: a filter (a) arranged in the excitation circuit of the intermediate frequency generator, a filter (b) arranged between the high-voltage compensating reactor and the sample and a filter (c) arranged between the generator outlet and the low-voltage compensating reactor. The system provides a simple and reliable power source system with little background interference for the extra high voltage partial discharge tests.
