DC high-voltage generator, high-voltage electrostatic generator

Product Introduction:

DC high voltage generator is used to detect the electrical insulation strength and leakage current of power devices. It is designed and manufactured according to the requirements of the Chinese industry standard ZBF 24003-90 "General Technical Conditions for Portable DC High Voltage Generators". It is a new era product, and the 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 ungrounded protection.

Product Features:

1. The product is small in size, lightweight, more aesthetically pleasing, reliable, easy to operate, fully functional, and convenient for outdoor use.

2. Applying PWM high-frequency pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices, and utilizing high-frequency technology to increase the frequency, the frequency can reach up to 100kHz, resulting in higher output high voltage stability and smaller Bowen coefficient.

3. The product has high precision and accurate measurement. Voltage and current are both 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 sample, without the need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage terminals for measuring leakage current, and the high voltage terminal is displayed with a circular screen shielded digital meter, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.
4. The product has high voltage regulation stability, smooth voltage regulation across the entire range, and uses a single multi turn potentiometer for output voltage regulation. The boosting process is smooth, the regulation accuracy is high, and it is designed with coarse and fine adjustment functions. The voltage regulation is better than 0.1%, the measurement error of voltage and current is less than 1.0%, and the pulsation factor is better than 0.5%.
5. The product has various protection functions such as negative polarity output, zero start, continuous adjustment, overvoltage, overcurrent, return to zero, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, and ensures safe operation.
6. The addition of high-precision 75% VDC-1mA function has brought convenience to the measurement of zinc oxide lightning arresters. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. When conducting the zinc oxide test of the lightning arrester, when the current rises to 1000uA, the 0.75 button is turned on. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, the voltage boosting knob should be immediately returned to the zero position. At the same time, the fine adjustment voltage knob should be returned to the zero position, and the green button should be immediately pressed to cut off the high voltage and turn off the power switch. Conduct other experiments.
7. The convenient overvoltage setting function of the DC high voltage generator adopts a digital dial switch, which can intuitively display the set voltage value, making your operation more flexible. The displayed value unit is kV
8. The double pressure cylinder of the DC high voltage generator can be divided into sections for on-site use, which is flexible and convenient. It can be used for multiple purposes and is economical. There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder

Notes:

1. To ensure personal safety, users are repeatedly reminded to pay attention to the good grounding of the control box and high-voltage tower, as well as the discharge issues of the test samples and high-voltage tower after shutdown.

2. Please do not cover the upper and lower ventilation holes of the control box, and prevent foreign objects from falling into the holes. If the control box has a fan, it should be checked regularly to ensure that the fan is running properly.

3. When the insulation cylinder of the high-voltage tower is dirty, please wipe it clean with a dry cloth. Do not use organic solvents such as alcohol or gasoline for scrubbing. Use detergent to clean the surface of the insulation cylinder. Wait for it to air dry before use; When transporting or not in use, please place it in an aluminum alloy box.

4. When replacing the fuse, please replace the fuse according to the rated amperage next to the fuse seat.

5. If the high voltage shielded microampere meter displays "LOW BAT", please replace the 9V battery to avoid measurement errors. When not in use, please turn off the power.

6. Do not open the control box and high-pressure tower without permission, as this will affect the warranty of the product. The manufacturer is not responsible for disassembling on their own.
