ZGF-200kV 300kV, DC Withstand Voltage Test Apparatus

This DC withstand voltage testing device is suitable for use in power, railway, chemical, mining, metallurgy, and steel industries

for DC withstand voltage and leakage tests on equipment such as zinc oxide surge arresters, magnetic blowout surge arresters, 

power cables, transformers, and generators. It can also be used as a power source for electrostatic dust collection and spraying.

1. The instrument is suitable for use in power, railway, chemical, mining, metallurgy, and steel industries for DC withstand voltage

 and leakage tests on equipment such as zinc oxide surge arresters, magnetic blowout surge arresters, power cables, transformers

 and generators. 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 applying the latest PWM pulse width modulation

 technology and voltage-current dual closed-loop feedback technology, it improves power supply regulation and load regulation,

 resulting in high voltage stability and low ripple.

Smooth voltage regulation across the entire range ensures high output voltage accuracy. The main unit voltmeter directly displays 

the voltage value applied to the load, eliminating the need for an external voltage divider and simplifying wiring and operation. 

Voltage resolution: 0.1kV; Current resolution: 1uA.

3. Comprehensive Protection: Features 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 protecting personnel and equipment safety.

3. 0.75U Function: Includes an intelligent, high-precision 0.75U function with a one-button button. Pressing this button automatically

 switches the voltage and current to the 0.75U state, facilitating the testing of zinc oxide surge arresters.

1. Split-type specifications: 200/2, 200/3, 200/5, 300/2, 300/3, 300/5
