The complete set of frequency conversion series resonance test equipment consists of a frequency conversion power supply, excitation transformer, high-voltage reactor, and capacitive voltage divider; The complete set of frequency conversion series resonance test equipment adopts the method of adjusting the frequency of the power supply to achieve resonance between the reactor and the tested capacitor, and obtain high voltage and high current on the tested object. The capacitor and reactor of the sample are connected in series resonance, and the voltage divider is connected in parallel with the sample. The resonant voltage is measured using a frequency conversion series resonance test set and an overvoltage protection signal is issued; The excitation transformer couples the FM power output to the series resonant circuit, providing excitation power for series resonance.
The complete set of frequency conversion series resonance test equipment has a high degree of automation, small size, and light weight. The weight of each unit in the complete set of equipment shall not exceed 40kg, and it is suitable for on-site handling. The reactor adopts dry epoxy casting, which is reliable in operation, easy to transport, and does not require lifting for on-site testing. Installation testing can be carried out manually. The frequency converter series resonance testing equipment is widely used in industries such as power, metallurgy, petroleum, and chemical.
