Technical Features
1. The GS103E fully automatic 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. The GS103E fully automatic intelligent DC high voltage generator pioneers intelligent poor grounding protection and alarm function (cannot boost voltage when grounding is poor), and can temporarily disable the poor grounding protection alarm function (such as when using a generator as power source or when poor grounding on site but testing is still possible). An emergency stop button is added, greatly improving operator safety during operation.
3. The GS103E fully automatic intelligent DC high voltage generator uses a 30-50kHz intelligent voltage doubling circuit, significantly reducing the volume and weight of the control box and voltage doubling cylinder, making it more convenient for field use. AIPWM technology is applied to adjust the inaccurate linearity of PWM technology, greatly improving instrument accuracy. AI technology is used to set overvoltage and overcurrent protection, replacing the digital dial switch that could 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, enabling the DC high voltage generator to withstand rated voltage discharge without damage.
4. The GS103E fully automatic intelligent DC high voltage generator adds AI fully automatic zinc oxide arrester measurement and oil-immersed or transformer measurement functions, and is specially designed with a 0.75UDC/1mA manual trigger button for zinc oxide arrester testing.
5. The GS103E fully automatic intelligent DC high voltage generator uses large voltage feedback, greatly improving voltage stability. It uses advanced components from the United States, Japan, and other countries. The voltage doubling cylinder is made of epoxy winding technology developed in Germany, reducing the instrument's self-leakage. The medium-frequency transformer is specially designed by experts, with small size and large capacity. The base of the voltage doubling cylinder contains a hidden △-Y support leg, which expands into a Y shape when in use for stable and convenient support, and contracts into a △ shape when packed, hidden inside the base.
6. The GS103E 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 optical isolation elements are also nanosecond-level. The action time is generally within 10 microseconds to completely cut off the DC main circuit. The drive signal is quickly turned off for protection. At the output end, dedicated sensors sample with nanosecond response time. Through nanosecond-level optical isolation elements and nanosecond-level analog switches, the entire process cuts off the drive signal of the power amplifier circuit within 2 microseconds, ensuring that power devices are not damaged in the event of output short circuit.
Safety Warnings for Use
1. Personnel conducting DC high voltage tests must be professionals with a "High Voltage Test Work Permit".
2. When using the RTZG-II series DC high voltage generator, users must comply with Article 168 of the "Electric Power Safety Regulations" and install two obvious disconnection points before the working power enters the tester.
3. When DC high voltage is 200kV and above, even if test personnel wear insulating shoes and stay outside the safety distance, due to the influence of high-voltage DC ion distribution, nearby human bodies may carry different DC potentials. Test personnel should not shake hands with each other or touch grounding bodies with their hands, otherwise there may be slight electric shock, which generally does not cause harm to people. Cable testing must use current limiting resistors.
4. When discharging large capacitance test objects, do not immediately contact the test object with the discharge rod. Gradually approach the test object with the discharge rod until the air gap begins to ionize and discharge with a hissing sound at a certain distance. When there is no sound, discharge with the discharge rod, and finally directly ground the wire for discharge.
