The NAIVG-200kV/10k~5600kV/560k series fully automatic lightning pulse impulse voltage generator is designed for indoor and outdoor use, using a three insulated column support structure. Connect three columns reliably at each stage of the generator and form a stable structure with each other.

Each stage of the generator has a low inductance, large capacity surge capacitor placed in the center of the surge voltage generator structure. This capacitor adopts high-density solid capacitors, which have the characteristics of light weight and small volume. Even when operated continuously under rated conditions, they have sufficient service life.

The structural characteristics of the lightning pulse impulse voltage generator body of Nan'ao Electric. All the electric anodes used on the generator are plug-in wire wound anodes. The modulated electric anode of lightning waves adopts a non inductive winding system with very small inductance. The wave head electric anode and wave star electric anode are installed between the two columns of the generator. The charging resistor is installed on one side of the ignition ball gap.

The DC charging power supply (consisting of a high-voltage transformer, a voltage doubling capacitor, and a high-voltage body stack) adopts a voltage doubling rectification method. The high-voltage silicon stack is installed on an insulating support plate, and its direction can be manually changed through a simple spring crimping mechanism. The DC high voltage is output to the first stage capacitor of the impulse voltage generator through a protective resistor. The high voltage and high resistance used to measure the charging voltage are also installed on this insulation support plate.

The ignition trigger of the generator is achieved by triggering the ball gap at the lowest level to discharge it. Therefore, the ball gap at the bottom level is designed as a three gap structure, and the triggering pulse is a high-level, rapidly changing pulse voltage. It is generated by an ignition pulse amplifier. A coupling capacitor for detecting the ignition pulse of the generator is installed on the base of the generator.

To ensure the safe operation of the generator, the system provides a grounding mechanism. Once an abnormality occurs in the generator, the grounding discharge switch will automatically ground after the first charging resistor, resulting in all surge capacitors being discharged through the lowest level resistor.
