Description
Overview
DC Hipot Test Kit 60kV 120kV adopts a high-frequency voltage double circuit, advanced PWM high-frequency pulse width modulation technology, closed-loop adjustment, and large voltage feedback, which greatly improves voltage stability. Use high-power IGBT devices and drive technology with superior performance, and adopt special shielding, isolation, and grounding measures according to electromagnetic compatibility theory. The Series dc high voltage generators are made of high quality, portable, and capable of withstanding rated voltage discharge without damage. It has the characteristics of large output power and small volume, reliable over-voltage, over-current, and zero-closing protection, with a 0.75 times voltage switching function. It is mainly used in the power sector, industrial and mining, metallurgy, steel, and other enterprise power departments to conduct DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment.
