The DC high-voltage generator is the latest research, design, and manufacture in accordance with the requirements of the Chinese industry standard ZBF 24003-90 "General Technical Requirements for Portable DC High-voltage Generators". It is a new era technology product-portable DC high-voltage generator, suitable for Electric power departments, scientific research institutions, railways, chemical industries, power plants, and large-scale enterprise power departments conduct DC high voltage tests and leakage current tests on zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, switches and other equipment.
Using pulse width modulation (PWM) technology, IGBT, and advanced electronic circuits and components, the output is not interfered by power grid fluctuations, and there are protective measures such as zero position, overcurrent, breakdown, and overvoltage, regardless of overcurrent, breakdown, The overvoltage protection circuit can act quickly, effectively guaranteeing the safety of equipment and personnel. Its output adopts liquid crystal display, and its volume and weight are much lighter than the original KGF type, which is very suitable for on-site use. The newly designed "0.75U" LCD can directly display and lock the 0.75U1mA field test without manual calculation.
High precision and accurate measurement. Both the voltage and current meters are digitally displayed, with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltmeter on the control box directly displays the voltage value added to the load sample. There is no need to add a voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends to measure the leakage current, and the high voltage end adopts a circular shielded digital meter to display, which is not afraid of discharge shock, has good anti-interference performance, and is suitable for on-site use.
High voltage regulation stability, full-scale smooth voltage regulation, output voltage regulation adopts imported single multi-turn potentiometer, the boosting process is stable, the regulation accuracy is high, and it is designed with coarse and fine adjustment functions. The voltage adjustment accuracy is better than 0.1%, the voltage and current measurement error is less than 1.0%, and the pulsation factor is better than 0.5%.
