What Are The Technical Characteristics of DC High Voltage Generator?

       The DC high-voltage tester produced by GDZX is a new-generation portable DC high-voltage tester designed and manufactured according to the Chinese power industry standard DL / T848.1-2004 "General Technical Conditions for DC High-voltage Generators". It is mainly suitable for the power sector, industrial and mining, metallurgy, steel and other enterprise power departments to conduct DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide surge arresters, power cables, transformers, and generators.

Technical characteristics of DC high voltage generator:

1. Small size, light weight, easy operation, complete functions, easy to use in the field, it is an ideal and reliable product in the new century.

2. Adopt advanced technology and process manufacturing, take the lead in applying the new PWM intelligent pulse width modulation technology, pulse string logic array modulation, using high-power IGBT devices, using intelligent technology to increase the intelligence rate, the frequency is up to 40kHz, so that the output high voltage stability is higher, the ripple factor is small.

3. Using computer control technology, display the output DC high voltage, current, overvoltage setting, timing, grounding and various protection information on the large-screen LCD display.

4. Intelligent ground fault protection and alarm function, pressure measurement circuit disconnection protection, emergency stop button, greatly improve the safety of the operator during the operation process. Under special circumstances, it can also release the poor grounding protection alarm function with high precision and accurate measurement. Both the voltage and the ammeter are digitally displayed with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltage meter on the control box directly displays the voltage value added to the load test product. There is no need to add an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends to measure the leakage current, and the high voltage end is displayed with a round shielded digital meter. It is not afraid of discharge shock and has good anti-interference performance. It is suitable for field use. 

5. The voltage regulation has high stability, smooth voltage regulation over the whole range, the output voltage regulation adopts imported single multi-turn potentiometer, the boosting process is stable, the regulation accuracy is high, and the coarse and fine adjustment functions are designed. The voltage regulation accuracy is better than 0.1%, the voltage and current measurement errors are less than 1.0%, and the pulsation factor is better than 0.5%.

6. The function of high-precision 75% VDC-1mA has been added, which brings great convenience for the measurement of zinc oxide surge arresters. There is no need to calculate with one touch. There is a 75% voltage function key on the control box of this instrument. When conducting the arrester test, when the current rises to 1000uA, the 0.75 button is turned on. At this time, the value displayed by the voltmeter and ammeter is 75% of the data. After that, the booster knob should be returned to the zero position immediately, and the fine-adjustment voltage knob should be returned to the zero position, and the green button should be pressed immediately to cut off the high voltage and turn off the power switch. Than do other tests.

7. The pressure multiplying cylinder can be divided into sections, and it can be used on site. It is flexible and convenient.

8. The voltage doubler body is developed by German technology; the intermediate frequency transformer is specially designed by the relevant experts, with small size and large capacity. 

9. It conforms to the technical requirements of DL / T848.1-2004, and has passed the type test of the Electrical Equipment Quality Inspection and Testing Center of the Ministry of Electric Power.
