ZGF 60kV 120kVDC Hipot Tester
The integrated design solution places the voltage multiplier and main unit in a single chassis. Combining the latest technology and components, it achieves advantages such as small size, high power, light weight, convenient operation, safety, reliability, and high-quality power output, making it an ideal testing instrument for the high-voltage testing industry.
The instrument is suitable for DC withstand voltage and leakage current testing of equipment such as zinc oxide surge arresters, magnetic blow-out surge arresters, power cables, transformers, and generators in power, railway, chemical, mining, metallurgical, and steel industries. It can also be used as a power source for electrostatic dust collection and spraying.
1. The instrument is suitable for DC withstand voltage and leakage current testing of equipment such as zinc oxide surge arresters, magnetic blow-out surge arresters, power cables, transformers, and generators in power, railway, chemical, mining, metallurgical, and steel industries. It can also be used as a power source for electrostatic dust collection and spraying.
2. Stable output voltage: Utilizing a high-frequency voltage multiplier circuit and the latest PWM pulse width modulation technology and voltage and current dual closed-loop feedback technology, it improves power supply regulation and load regulation, resulting in high voltage stability and low ripple. Full-range smooth voltage adjustment and high output voltage accuracy.
The main unit's voltmeter directly displays the voltage value applied to the load, eliminating the need for an external voltage divider and simplifying wiring. Voltage resolution is 0.1kV, and current resolution is 1uA.
3. Comprehensive protection: Complete protection functions include zero-position protection, overvoltage protection, overcurrent protection, and breakdown protection. The protection circuit uses nanosecond-level dedicated sensors for fast and reliable operation, effectively ensuring personal and equipment safety.
4. 0.75U function: An intelligent high-precision 0.75U function button is added. Pressing this button automatically switches the voltage and current to the 0.75U state, facilitating the testing of zinc oxide surge arresters.
