Fm-type Series Resonant Ac High Voltage Test Device Developed

A new type AC high voltage tester is developed in this paper. This device realizes series resonance between high voltage inductance and tested capacitance. Because of series resonance a higher voltage exists on the tested capacitance than the power's output. So a new AC high voltage test way to large capacity sample comes true. This device has hereinafter characteristics.1. It can do large capacity sample test by small capacity power.2. The output frequency and output voltage of this device are very stable and they can be adjusted continuously. It can be applied to most electric power equipment to do AC high voltage test.3. This device is more small and light. It is convenient to transport and test on the spot. The device has more advantage than traditional adjustable AC high voltage design. It adopts adjustable method to make adjustable series resonance even easier and the change extend of tested much wider. It is fit to test the majority of electricity system design. The device works under the frequency of 50-300HZ. It is very strict with the requirement of the tested.The process of the design takes many kinds of anti-jammed and protective measures. The system works steadily and reliably. Through many imitation tests show that not only it has more advantage but also it has good developing and market promising.
