The ZGF DC high-voltage generator adopts an intermediate frequency voltage doubling circuit, applies PWM pulse width modulation technology and high-power IGBT devices. According to the theory of electromagnetic compatibility, special shielding, isolation, and grounding measures are adopted to achieve high regulation accuracy, simple operation, small size, light weight, and convenience for the power department. The enterprise power department conducts DC high voltage tests on equipment such as zinc oxide lightning arresters, power cables, generators, transformers, and switches.
