Let's take a look at these before using a DC high-voltage generator!

　　DC high voltage generatorAdopting intermediate frequency voltage doubling circuit, applying PWM intermediate frequency pulse width modulation technology, closed-loop adjustment, and adopting voltage feedback, the voltage stability is greatly improved. Using high-power IGBT devices and their driving technology, and based on electromagnetic compatibility theory, adopting special shielding, isolation, and grounding measures. The high-voltage generator has high quality, portability, and can withstand rated voltage discharge without damage.

The main components of the instrument are selected with advanced technology components, making the instrument more reliable and stable. The pressure doubling cylinder has a small volume, large capacity, strong overload capacity, and is convenient for on-site operation and testing. Suitable for DC high voltage testing of equipment such as zinc oxide lightning arresters, magnetic blow lightning arresters, power cables, generators, transformers, switches, etc. in the power sector, power plants, research institutions, railways, chemical industries, and power plants.

Instructions for Use:

1. High frequency output and voltage/current measurement cables are quickly connected to multi-core sockets: used for connecting the chassis with the voltage doubling part. When connecting, simply align the white dot on the cable plug with the white dot on the socket and rotate it clockwise to the correct position. To disassemble, simply turn the cable plug counterclockwise. Attention: When installing or removing the plug, please grip the metal ring of the plug tightly and rotate it. It is strictly prohibited to hold and pull the cable to rotate, in order to avoid disconnection between the plug and the cable.

2. Power fuse holder: The fuse is 10A.

3. Power input socket: single-phase AC 220V ± 10%, 50HzDC high voltage generatorThe configured power cord is connected to the power input socket (the socket comes with a 10A fuse or a separate fuse holder).

4. Grounding terminal: This grounding terminal is connected to the grounding terminal of the voltage doubling cylinder and the grounding of the test sample at one point, and then connected to the grounding grid.

5. Overvoltage setting dial switch: used to set the overvoltage protection value. The overvoltage setting range is within 0.05-1.2 times the rated voltage, and the displayed value of the dial switch is in kV.

6. Red illuminated button, high voltage connection button, high voltage indicator light: When the green light is on, pressing the red button will turn on the red light and off the green light, indicating that the high voltage circuit is connected. At this time, the voltage can be increased. This button is only effective when the voltage regulating potentiometer is reset to zero. If the red button is pressed and the red light is on while the green light is still on, but the button is released and the red light goes out and the green light is on, it indicates that the internal protection circuit is working. At this time, turn off the machine and check if the overvoltage setting dial switch is less than 5% of the full range and if there are any other faults. After confirming that there are no errorsDC high voltage generatorTurn it on again.
