ZGF-200kV 300kVDC withstand voltage test device

This 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:  Using a high-frequency voltage multiplier circuit and the latest PWM pulse width modulation technology and voltage and current dual closed-loop feedback technology, the power supply regulation rate and load regulation rate are improved, resulting in high voltage stability and low ripple.

Smooth voltage adjustment across the entire range, with 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, simplifying wiring and operation. Voltage resolution is 0.1kV, and current resolution is 1uA.

3. Comprehensive protection:  Complete protection functions, including zero-position protection, overvoltage protection, overcurrent protection, and breakdown protection. The protection circuit uses nanosecond-level dedicated sensors, ensuring rapid and reliable operation and effectively guaranteeing personal and equipment safety.

3. 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.
