Abstract
The invention relates to a power device for a controlled electric reactor induced over voltage withstand test. The power device comprises a variable-frequency power cabinet, an intermediate transformer, a voltage gauge, a controlled electric reactor and a partial discharge testing instrument. The variable-frequency power cabinet is in circuit connection with the intermediate transformer. The intermediate transformer is in circuit connection with the voltage gauge. The voltage gauge is in circuit connection with the controlled electric reactor. The controlled electric reactor is in circuit connection with the partial discharge testing instrument. A partial discharge test is conducted through the arranged partial discharge testing instrument. The voltage in the circuit is controlled in real time through the intermediate transformer and the voltage gauge which are connected to the circuit in series, and therefore the stability of discharge detection is guaranteed.
