dc high potential hipot test equipment

The dc high potential hipot test equipment high-voltage direct current generator is an instrument that generates high-voltage direct current. It is mainly used for insulation testing of power equipment, leakage current tests, and DC withstand voltage tests. It complies with international and industry standards such as IEC 60-1 and DL/T 848.1. It adopts a sectional design and can flexibly adapt to testing requirements of different voltage levels ranging from 35kV to 220kV. It supports DC tests for equipment such as zinc oxide arresters and cables.
The dc high potential hipot test equipment core of this device uses PWM pulse width modulation technology, high-power IGBT components, and intermediate frequency voltage boosting circuits. Combined with electromagnetic compatibility shielding design, it ensures stable output. It has nanosecond-level rapid protection functions, including multiple safety protection mechanisms such as overvoltage, overcurrent, and poor grounding, and integrates an intelligent micro-ammeter and 0.75 times voltage lockout function, enabling precise measurement of the Industrial High Voltage Hipot Tester characteristics of arresters. The working power supply is AC220V, with a measurement accuracy of 1.0% and a ripple coefficient of ≤0.5%. It is suitable for on-site testing in the fields of power, industry, and research. Main models include high-frequency voltage boosting, portable, and intelligent control types, meeting the needs of various testing scenarios.
