Intelligent DC High Voltage Generator - DARUI Electric
DARUI Electric recommends for you
Product Features
1. Intelligent DC High Voltage Generator adopts computer control technology to control AIPWM pulse width modulation, measurement, protection, and display. It displays output DC high voltage, current, voltage setting, current setting, timing, and protection information on the LCD screen, and is equipped with a USB interface and printer for real-time storage or printing of test data.
2. It pioneers intelligent poor grounding protection and alarm function (cannot boost voltage when grounding is poor), and can cancel the poor grounding protection alarm once (such as when using a generator as power source or when grounding is poor but testing can still proceed). An emergency stop button is added, greatly improving operator safety during operation.
3. It adopts a 30-50kHz intelligent voltage doubler circuit, which significantly reduces the volume and weight of the control box and voltage doubler cylinder, making it more convenient for field use. AIPWM technology is applied to adjust the non-linearity of PWM technology, greatly improving the instrument's accuracy. AI technology is used to set overvoltage and overcurrent protection, replacing the digital dial switch that can only set voltage value but not current value and voltage drift. According to electromagnetic compatibility theory, special shielding, isolation, and grounding measures are adopted to achieve high quality, withstand rated voltage discharge without damaging the machine.
4. The SBGF fully automatic intelligent DC high voltage generator adds AI fully automatic zinc oxide arrester measurement and oil-immersed or transformer measurement functions, and reserves a manual trigger button of 0.75UDC/1mA specially designed for zinc oxide arrester testing.
5. SBGF adopts large voltage feedback, greatly improving voltage stability. It uses components from American and Japanese technologies; the voltage doubler cylinder is made with German technology developed epoxy winding technology, reducing the instrument's own leakage; the intermediate frequency transformer is specially designed by experts, small in size and large in capacity. The base of the voltage doubler cylinder hides △-Y support legs, which expand into Y shape when in use for stable support, and shrink into △ shape when packed, hidden in the base.
6. The SBGF fully automatic intelligent DC high voltage generator has multiple protection functions, such as low-voltage overcurrent, low-voltage overvoltage, high-voltage overcurrent, high-voltage overvoltage, zero-position protection, and non-grounding protection. Fault sampling uses dedicated sensors with nanosecond response time, and the optical isolation components are also nanosecond-level, with action time generally within 10 microseconds to shut off the DC main circuit. The drive signal fast shutdown protection uses dedicated sensors at the output end for sampling, with nanosecond response time. Through nanosecond-level optical isolation components and nanosecond-level analog switches, the drive signal of the power amplifier circuit is cut off within 2 microseconds, ensuring that power devices are not damaged in case of output short circuit.
