Cable frequency conversion resonance, cable resonance
The cable special frequency conversion resonance test device adopts the method of adjusting the frequency of the power supply to make the reactor and the capacitor under test achieve resonance, and obtain high voltage and large current on the test product. It is a new method and trend of current high voltage test. It has been widely used at home and abroad.
The cable special frequency conversion resonance test device uses a special SPWM digital waveform generator chip with a frequency resolution of 16 bits, and the frequency fineness can reach 0.1Hz at 20~300Hz; the SXRC series cable special frequency conversion resonance test device adopts orthogonal non-synchronization The fixed carrier modulation method ensures that the output waveform is good in the entire frequency range; the power part adopts the advanced IPM module to ensure the stability and safety of the instrument under the minimum weight.
The special frequency conversion resonance test device for cables is composed of a frequency and voltage regulation power supply, an excitation transformer, a reactor, and a capacitor voltage divider.
