Product Introduction: The FSZGF series DC high-voltage tester is a new generation of portable DC high-voltage test equipment designed and manufactured according to the latest Chinese electric power industry standard DL/T848.1-2004 "General Technical Conditions for DC High-Voltage Generators". It is mainly suitable for DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, and generators in power departments, industrial and mining enterprises, metallurgy, steel, and other enterprises' power departments.
The FSZGF series DC high-voltage tester adopts a high-frequency voltage doubling circuit, applies the latest PWM pulse width modulation technology and voltage and current dual closed-loop feedback technology, improves power supply regulation rate and load regulation rate, making the voltage stability high and ripple small. It uses imported high-power IGBT devices and their driving technology to eliminate switching interference, achieving high quality and portability of the DC high-voltage generator. It selects imported high-frequency high-voltage rectifier diodes, making the voltage doubling cylinder more compact and lightweight, improving the overall efficiency of the machine.
The FSZGF series DC high-voltage tester adopts an integrated design scheme: the voltage doubling cylinder and the main unit are placed in one chassis, combined with the latest technology and the latest components, achieving advantages such as small size, high power, light weight, convenient operation, safety and reliability, and high power output quality. It is an ideal test instrument for the high-voltage testing industry.
