MEWOI8500H Intelligent DC high voltage generator The smart high voltage direct current generator is mainly used for DC withstand voltage test or DC leakage current test of high voltage electrical equipment zinc oxide arrester, power cable, transformer, circuit breaker, generator in power departments of power sector, industry, metallurgy, iron and steel and other enterprise etc.
MEWOI8500H Intelligent DC high voltage generator applies AIPWM technology, has adjusted the inaccuracy linearity of PWM technology, the instrument accurate has been improved greatly. And the AI technology has been adopted to set overvoltage protection and overcurrent protection, which replaced the digital dial switch that can only set the voltage value, unable to set current value and voltage drift, has kept the manual 0.75UDC1mA function.
MEWOI8500H Intelligent DC high voltage generator is widely applied in the DC HV tests carried out for the zinc oxide lightening arrester, magnetic blow-out arrester, power cable, generator, transformer, circuit breaker, etc.
|1.Use large touch LED screen with human-machine dialogue function;|
2. Full-automatic MOA voltage rise measuring function: good repeatability, high accuracy;
3. Automatic voltage rising function: With preset test voltage, the output voltage can be maintained constant;
|4. Automatic timing function: Preset the voltage rising time of the standard test voltage, after rising to the standard test voltage, the timing will start automatically, when the timing is completed the voltage will drop automatically;|
5. The HV over-voltage setting uses micro-processor for setting, which is highly precise and highly reliable;
6. Preserve the manual test mode;
7. Data storage function: Being able to timely catch the test parameters and automatically preserve the test results;
8. Based on the electromagnetic compatibility theory, use the special shielding, multi-level isolation and grounding and various other protection strategies to form a organized protection combination, during discharging under rated voltage the equipment will not be damaged;
|9. HF, ZGF totally intelligent series of DC HV tester possesses the online operation function with built-in online control software. The host computer (such as being equipped with PC) is installed with control software and auxiliary communication cable (optional) which can realize the online control.|
