Frequency series-resonant voltage test equipment

Frequency series-resonant voltage test equipment The principle is to use series resonance, by adjusting the frequency controller's output frequency

Frequency series-resonant voltage test equipment Product Description
FM sets of series-parallel resonant series resonance test device is to use the principle, by adjusting the frequency controller's output frequency, makes the circuit of the reactor inductance L and capacitor C test items occurred series resonance, resonant voltage increases on the goods shall be test voltage.
  Complete sets of series-parallel resonant frequency test equipment is widely used in electric power, metallurgy, petroleum, chemical, etc., suitable for large-capacity, high-voltage capacitive test products, such as generators, transformers, GIS, high-voltage cross-linked cables, transformers, casing, etc. transfer experiments and preventive trials.
  I plant in the FM series-parallel resonant high-pressure experiments, self-developed FM, voltage software technology, leading the industry in the domestic high-pressure test, using this technology uses 16-bit precision FM, 10KHZ carrier frequency, SPWM and import of original modular design of the overall IPM and manufacture complete sets of FM series-parallel resonance test device, in full compliance with the relevant national procedures and requirements of high-pressure experiments.
Frequency series-resonant voltage test equipment Composed of sets of equipment parts
Whole device consists of FM power host, excitation transformers, reactors, voltage divider, compensation capacitor, the test line containers.
