JKXB series portable frequency conversion resonant device

The JKYB series cable portable frequency conversion resonant boosting device adopts the method of adjusting the frequency of the power supply, so that the reactor and the tested capacitor can achieve resonance, and obtain high voltage and high current on the tested object. It is a new method and trend of high voltage testing, which has been widely used at home and abroad.
The JKYB series frequency conversion resonant boost device adopts SPWM digital waveform generation chip with a frequency resolution of 16 bits, and the frequency fineness can reach 0.1Hz between 20-300Hz. It adopts orthogonal asynchronous fixed carrier modulation method to ensure good output waveform in the entire frequency range; The power part adopts IPM module to ensure instrument stability under weight.
The JKYB series variable frequency resonant boosting device consists of a frequency and voltage regulating power supply, an excitation transformer, a reactor, and a capacitive voltage divider.
Product nickname: Variable frequency resonance, Variable frequency series resonance, Series resonance, Series resonance transformer, Series resonance testing equipment, Portable cable withstand voltage testing device
Main functions and features:
1. Cables with voltage levels of 35kV and below are widely used and require a large amount of testing work. Therefore, this type of voltage withstand test device is small in size and light in weight, giving rise to portable cable voltage withstand test systems
2. This system requires that the weight of components that a single person can move on site should not exceed 30kg, and the weight of components that two people can move on site should not exceed 60kg, which is suitable for on-site handling
3. The power supply adopts 220V single-phase power supply or 380V single power supply, which is convenient for on-site power supply
4. The reactor part adopts dry-type epoxy casting, which is beautiful and reliable, suitable for the requirements of various types of cables
5. Oil immersed reactors are used for the withstand voltage test of cables with voltage levels of 110kV and above. When the individual weight is greater than 100kg, our company's small electric crane can be optionally equipped
