How to use the portable DC high voltage generator? 1. Smaller in size, lighter in weight, more beautiful, more reliable, easy to operate, complete in functions, and easy to use in the field, it is an ideal and reliable product in the new century. 2. Manufactured with advanced technology and craftsmanship, how to use the new portable DC high voltage generator? 1. Smaller in size, lighter in weight, more beautiful, more reliable, easy to operate, complete in functions, and easy to use in the field, it is an ideal and reliable product in the new century. 2. Using advanced technology and process manufacturing, applying new PWM intelligent pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices, using intelligent technology to improve the intelligence rate, the frequency is up to 40kHz, so that the output high voltage stability is higher, ripple coefficient is smaller.
3. Using computer control technology, the output DC high voltage voltage, current, overvoltage setting, timing, grounding and various protection information are displayed on the large-screen LCD display. 4. Intelligent poor grounding protection and alarm function (poor grounding cannot boost voltage), pressure measuring circuit disconnection protection (high voltage measuring loop disconnected instrument cannot boost voltage), emergency stop button, which greatly improves the safety of operators during operation. In special circumstances, the poor grounding protection alarm function can also be released (such as when a generator is used as the power source or the field grounding is poor but the test can still be performed.
) high precision and accurate measurement. Both the voltage and ammeter are displayed digitally, 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 applied to the load test sample. There is no need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends to measure leakage current, and the high voltage end is displayed by a circular shielded digital meter, which is not afraid of discharge impact, has good anti-interference performance, and is suitable for on-site use.
5. High voltage regulation stability, smooth voltage regulation in full range, output voltage regulation using imported single multi-turn potentiometer, stable boosting process, high regulation accuracy, and designed with coarse adjustment and fine adjustment functions. The voltage regulation accuracy is better than 0.1%, the voltage and current measurement errors are less than 1.0%, and the ripple factor is better than 0.5%. 6. The function of high-precision 75%VDC-1mA is added, which brings great convenience to the measurement of zinc oxide arresters.
A single tap doesn't count. There are 75% voltage function keys on the control box of the instrument. During the arrester test, when the current rises to 1000uA, turn on the 0.75 button. At this time, the value displayed by the voltmeter and ammeter is 75% of the data. After that, the boost knob should be returned to the zero position immediately, and the fine adjustment voltage knob should be returned to the zero position at the same time, and the green button should be pressed immediately to cut off the high voltage and turn off the power switch. Do another test.
