IPC: H01G13/00
Filed: 1992-11-17
Abstract: PURPOSE:To decide replacement time of a smoothing capacitor by a method wherein the progress of deterioration in the capacity of the capacitor is detected directly. CONSTITUTION:A resistance 4 is connected in parallel with a smoothing capacitor 3 composed of an aluminum electrolytic capacitor, and a contactor 5 is connected in series with the resistance 4. The contactor 5 is opened when an inverter 11 is operated. In addition, a voltage detector 7 is connected in parallel with the smoothing capacitor 3. After a power supply to the inverter 11 has been turned off, the contactor 5 is close an electric charge which has been stored in the smoothing capacitor 3 is discharged, and a voltage at this time is detected by the voltage detector 7. The time in which the voltage is attenuated is measured by a discharge-time measuring circuit 8. A deterioration decision circuit 9 compares the obtained discharge time with a preset reference time. When the discharge time is the reference time or lower, a deterioration decision signal is output via an interface 10.
