GOZ-ZGF DC high voltage generator has large output power, small size, light weight, safe and reliable features. It also has advantages of reliable during over-voltage and over-current, zero closing protection, with 0.75 times the voltage latching, and with time relay, voice alarm. It is mainly used in national and company power sector, research institutes, railway, chemical industry, power plants for DC high voltage test of zinc oxide surge arresters, magnetic blow arrester, power cables, generators, transformers, switches and other equipments. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities’ inspection, and issue a DC high voltage test report.
Also called: high voltage generator, IF DC high voltage generator, split DC high voltage generator, DC high voltage generation equipment
1． Smaller in size, lighter weight, more reliable, easy operation, full functions, easy for field using, the most ideal product.
2． Using the most advanced technology, manufacturing technology, the first application of the latest high-frequency PWM pulse width modulation technology, burst modulation logic array, using high-power IGBT devices, using high-frequency technology to improve the frequency which is up to 100kHz resulted in high stability of the high-voltage output and smaller ripple coefficient.
3． Maintenance-free design, the main components are imported from the United States, Germany, Japan and other countries, for they are durable and not afraid of continuous direct short discharge.
4． High precision. Voltage and current meter are digital display with voltage resolution of 0.1kV and current resolution 0.1uA.Control box voltmeter displays directly the load test voltage value, so no external voltage divider needs and with simple wiring. The instrument has high and low ends of measuring display for the leakage current, while high end digital table shows the circular shield, which is not afraid of the impact from discharge. With good anti-jamming performance, it is especially suitable for field use.
5． High stability for voltage regulation. Smooth voltage during full-scale, output voltage is adjusted by imported single multi-turn potentiometer, so there is smooth during voltage step up, high precision, and coarse and fine control features. Voltage regulation accuracy is better than 0.1%, voltage and current measurement error is less than 1.0%, ripple factor is better than 0.5%.
6． Negative output, zero start, continuously adjustable, over-voltage, over-current, back to zero, ground fault and disconnection protection and other protection functions. Automatic circuit protection feature is strong, comprehensive and reliable, so the operation is safe, and various technical indicators are better than the industry standard and superior to similar products.
7． It has addition function of high-precision 75% VDC-1mA which brings great convenience to MOA measurement. Touch without calculations. The instrument has 75% of the voltage control function button, when doing arrester test and current rises 1000uA, open 0.75 button, then the value is 75% of the data voltmeter and ammeter showing. After finishing test, immediately put the voltage step-up button back to zero, fine control button back to zero, and press the green button in the same time, high voltage power turns off, then other test can be done.
8． Convenient overvoltage tuning setting function, using the digital dial switch, tuning voltage visualize display, so that you operate more freely. The display value is in units of kV.
9． Voltage multiplier can be divided, field using flexible, and affordable.
10． In the bottom has three support legs, increasing stability for the voltage multiplier.
