Intelligent Medium-Frequency DC High Voltage Generator
Features and Main Functions
1. Smaller size, lighter weight, more attractive appearance, more reliable, easy to operate, and fully functional, making it ideal for field use. It is the most ideal reliable product of the new century.
2. Manufactured with advanced technology and processes, it pioneers the application of PWM high-frequency pulse width modulation technology and pulse train logic array modulation. It uses high-power IGBT devices and high-frequency technology to increase the frequency up to 100kHz, resulting in higher output voltage stability and smaller ripple coefficient.
3. Designed for maintenance-free operation, the main components are selected from advanced imported components from the United States, Germany, Japan, and other countries, ensuring durability and resistance to continuous direct short-circuit discharge to ground.
4. High precision and accurate measurement. Both voltage and current meters are digital displays, with voltage resolution of 0.1kV and current resolution of 0.1uA. The voltage meter on the control box directly displays the voltage applied to the load test object, eliminating the need for an external voltage divider and simplifying wiring. The instrument can measure leakage current at both high and low voltage ends. The high-voltage end uses a circular shielded digital meter display, which is resistant to discharge impact and has good anti-interference performance, suitable for on-site use.
5. High voltage regulation stability, smooth voltage adjustment across the full range. The output voltage adjustment uses an imported single multi-turn potentiometer, ensuring a stable voltage increase process and high adjustment precision, with coarse and fine adjustment functions. Voltage adjustment precision is better than 0.1%, voltage and current measurement error is less than 1.0%, and ripple factor is better than 0.5%.
6. Negative polarity output, zero-start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return-to-zero, grounding protection, and unique open-circuit protection. The automatic protection circuit is powerful, providing complete and reliable protection for safe operation. All technical indicators are superior to industry standards and similar products.
7. Added high-precision 75% VDC-1mA function, bringing great convenience to zinc oxide arrester measurement. A simple press without calculation is all it takes. The control box of this instrument has a 75% voltage function key. When performing arrester tests, when the current rises to 1000uA, press the 0.75 button. The values displayed on the voltage and current meters are the 75% data. After completion, immediately return the voltage increase knob to zero, and also return the fine voltage adjustment knob to zero. Then immediately press the green button to cut off the high voltage and turn off the power switch before proceeding with other tests.
8. Convenient overvoltage setting function, using a digital thumbwheel switch to display the set voltage value intuitively, making operation more flexible. The displayed value unit is kV.
9. The voltage doubling cylinder has a segmented structure, providing flexible and convenient on-site use. One machine can serve multiple purposes, offering economic benefits.
10. Three built-in support legs at the bottom increase the stability of the voltage doubling cylinder.
