Structure and Working Principle of DC High Voltage Generator
GS series DC high voltage tester
The ZGS series products have undergone many improvements. The whole machine adopts thick film circuit large board structure, with clear and reasonable circuit layout and high reliability. The high voltage part uses light thin-wall composite special insulation materials, with good electrical performance and strong impact resistance. High-frequency PWM pulse width modulation ensures stable output voltage and small ripple coefficient. It has 0.75UDC/1mA function, which is beneficial for zinc oxide arrester tests. Hall element protection provides strong impact resistance.

The ZGS series is an impact-resistant, high-stability DC high voltage tester. It has large power margin, strong overload capacity, stability better than 0.3%, adjustment fineness of 0.2%, ripple less than 0.3%, and the control box volume is only 3/4 of ZGS. The circuit is more optimized, layout is clear and reasonable, and it adopts a large printed board flip structure (patented), which is easy to debug and maintain. It has a wide range of applications. It can be used for high-current charging, such as testing large capacitance samples like power cables and generators. Due to its good stability and small ripple, it can also be used as a high-voltage stabilized power supply, and is more suitable for conductivity current tests of zinc oxide arresters.

200kV 100/200 3-5 600/1000 420×320×158 φ180×1180 33 Large power margin, according to user requirements, can be upgraded from intermittent use to continuous use, making it an ideal high-voltage DC power supply. The driving part uses a more integrated thick film circuit, making the anti-interference performance more excellent. Structurally, it adopts a plug-in-free large printed board flip structure, making the circuit clearer and more reasonable, with strong maintainability. The protection system uses Hall elements, improving the protection response time to a few microseconds. Performance indicators are more excellent: stability ≤0.3%, adjustment fineness 0.2%, accuracy ≤0.5%, ripple ≤0.3%.
