SYZGF300-5 DC high voltage generator Introduction: SYZGF DC high voltage generator is a portable DC high voltage generator researched and manufactured according to the requirements of Chinese industry standard ZBF 24003-90 "General technical conditions for portable DC high voltage generator". It is suitable for power department, power station of enterprise and mining enterprise, scientific research unit. DC, high voltage tests on equipment such as zinc oxide surge arresters, magnetic blow arresters, power cables, generators, transformers, switches, etc. in railways, chemical industries, and power plants. SYZGF DC high voltage generator adopts intermediate frequency double voltage circuit, which is the first to apply the latest PWM intermediate frequency pulse width modulation technology, closed loop adjustment, and adopts large voltage feedback, which greatly improves voltage stability. Use high-power IGBT devices with excellent performance and their driving technology, and adopt special shielding, isolation and grounding measures according to electromagnetic compatibility theory. The DC high voltage generator is made of high quality, portable, and can withstand rated voltage discharge without damage. Features: 1. Similar products are smaller in size, lighter in weight, more beautiful, more reliable, simple in operation, complete in function, and convenient for field use; 2, using advanced technology, process manufacturing, the first to apply the latest PWM IF pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices and large voltage feedback, so that the output high-pressure stability is higher, the ripple coefficient is smaller; 3. The main components of the instrument are all imported from the United States, Germany, Japan and other countries to import advanced technology components, durable, not afraid of continuous short-circuit discharge to the ground; 4. High precision and accurate measurement. The voltage and current meters are digital display, the voltage resolution is 0.1kV, and the current resolution is 1uA. The voltage meter on the control box directly displays the voltage value added to the load test sample. It does not need to be externally applied, and the wiring is simple. The instrument has high and low voltage terminals to measure leakage current, and the high voltage end is displayed by circular shielding digital meter. It is not afraid of discharge shock and has good anti-interference performance, suitable for field use; 5, high voltage regulation stability, full range smooth voltage regulation, output voltage regulation using imported single multi-turn potentiometer, smooth boosting process, high adjustment accuracy; 6, negative polarity output, zero start, continuous adjustable, over voltage, over current, zero return, ground protection, special disconnection protection and other protection functions. The automatic protection circuit has strong functions, perfect protection and reliability, and makes the operation safe. Various technical indicators are superior to the industry standards; 7. The DC high-voltage generator adds a high-precision function of 75% U DC-1mA, which makes the measurement of zinc oxide arrester extremely convenient. No one calculation is required with a single touch. There is 75% voltage function button on the control box of the instrument. When the current is raised to 1000uA, when the current rises to 1000uA, the button of 0.75UDC--1mA is pressed. At this time, the value displayed by the voltmeter and ammeter is 75%. The data should be turned back to zero immediately after completion, and the green button should be pressed immediately to cut off the high voltage and turn off the power switch. Do other tests; 8, convenient over-voltage setting function, using the digital dial switch, can display the set voltage value visually, so that you operate more casual, the display value unit is kV; 9. The double pressure cylinder is developed and produced by American technology. The intermediate frequency transformer is specially designed by relevant experts, with small volume, large capacity and strong overload capacity, which is convenient for field operation test; 10. There are three built-in support feet at the bottom to increase the stability of the double pressure cylinder; 11. The upper cover of the control box can be used as a windproof base, which can be inserted into the double pressure cylinder to enhance the stability of the double pressure cylinder.
