Embodiment Construction

[0011] Power capacitor overvoltage cycle test equipment, the equipment includes seven parts of the front stage switching power supply cabinet, voltage regulator, isolation transformer, excitation transformer, capacitor voltage divider, thyristor quick-break switch and intelligent console, the front stage switch The power supply cabinet provides power for the whole set of equipment. The voltage regulator adjusts the voltage to the voltage required for the overvoltage cycle test of the test product. The thyristor quick-break switch provides instantaneous double voltage for the test product. The intelligent The console controls and measures the secondary voltage and current of the two voltage regulators and the secondary voltage and current of the excitation transformer, and simulates the measured waveforms at 1.1 and 2.25 times the voltage of the test capacitor.
