Frequency conversion series resonance test system is also called series resonance, which is composed of frequency conversion power supply, excitation transformer, reactor and capacitance divider. The capacitor and reactor of the tested product form a series resonant connection mode; The voltage divider is connected in parallel with the test object to measure the resonant voltage on the test object and act as the overvoltage protection signal; The frequency-modulated power output is coupled to the series resonant circuit through the excitation transformer to provide the series resonant excitation power.
Wuhan huayi electric power technology is professional manufacturer of variable frequency series resonance test system in China. According to the test requirements of Egyptian customer, we provide professional solutions, the same equipment can do withstand voltage test on different subjects.
The solution was confirmed by customer and price can be met the target after adjusted.
