Located in an international metropolis, Shanghai Xuce Electric Technology Co., Ltd. is the most powerful manufacturer of power detection equipment. Our main products are: grounding resistance tester, DC resistance tester, insulation resistance tester, and frequency conversion series resonance test. Complete sets of devices, shunts, AC/DC voltage dividers, transformer characteristic testers, frequency conversion series resonant withstand voltage testers, automatic capacitance inductance testers, lightning protection device testers, DC high voltage generators, zinc oxide surge arresters, etc. .
Frequency conversion series resonant voltage withstand test device (series resonance) is widely used in electric power, metallurgy, petroleum, chemical, and other industries, and is suitable for large-capacity, high-voltage capacitive test products, such as generators, transformers, GIS, high-voltage cross-linked cables , Transformer, 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 ahead of 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 manufacture. The frequency conversion series-parallel resonance test set-up (series resonance) is in full compliance with the national regulations and requirements for high-voltage experiments.
Series resonant frequency voltage test equipment works <br> <br> reactor L and a capacitor C consisting of the test series resonator has a fixed resonance frequency F = 1 / (2π√L · C ) when the test frequency is equal to At this frequency, the circuit resonates. The variable frequency series resonance test equipment (series resonance) uses the principle of series-parallel resonance and adjusts the output frequency of the frequency conversion controller so that the inductance L of the reactor in the loop and the capacitance C of the sample product resonate. The resonant voltage is the Add voltage. 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 a desired voltage value.
The frequency conversion series resonant withstand voltage test device completes the composition of the â—‡ frequency modulation power supply - it can change its output frequency, but also can change its output voltage.
â—‡ reactor - in series with the sample, constitute the LC series resonant circuit.
Excitation magnetic transformer - acts as a coupling signal and voltage change, and increases the voltage according to its own changes.
Tantalum Divider - Measure the voltage on the sample and feed it back to the FM power supply as a sample signal.
â—‡ compensation capacitor - to compensate for the small capacity of the test sample, adjust the frequency of the sample.
