Intelligent portable frequency conversion series resonant test device working principle

Intelligent portable frequency conversion series resonant test device Direct Product Description:

Widely used in electric power, metallurgy, petroleum, chemical, and other industries, suitable for large-capacity, high-voltage capacitive test products, such as generators, transformers, GIS, high voltage cross-linked cables, transformers, casing and other transfer experiments and Preventive tests. The company's independent research and development of frequency conversion and voltage regulator software in the field of variable frequency series resonant high voltage test is superior to the domestic high voltage test industry. It uses this technology to adopt 16-bit fine frequency conversion, 10KHZ carrier frequency, SPWM and imported original IPM overall module design and manufacturing. The frequency conversion series-parallel resonance test set is in full compliance with the national regulations and requirements for high-voltage experiments.

Intelligent portable frequency conversion series resonant test device Direct working principle:

The frequency conversion series resonance test device uses the principle of series-parallel resonance and adjusts the output frequency of the inverter controller so that the inductance L of the reactor in the loop and the capacitor C of the sample resonate. The resonant voltage is the voltage applied to the sample. Through the frequency modulation controller to provide power supply, the test voltage through the excitation transformer after a preliminary boost, so that high voltage is added to the reactor L and the test sample CX, by changing the output frequency of the FM controller, so that the circuit is in series resonance; The resonant frequency of the loop depends on the capacitance CX of the test object and the inductance L of the reactor, and the output voltage of the inverter controller is adjusted so that the high voltage on the sample reaches the required voltage value.
