Product Description

Portable DC High Voltage Generator

It adopts medium-high frequency rectification and filtering technology, which solves the disadvantages of ordinary medium-low frequency high voltage generating devices, such as large ripple coefficient and unstable waveform. This series of products meets the requirements of the newly promulgated national power industry standard ZBF24003-90 "General Technical Conditions for DC High Voltage Generators DL/T 848.1—2004", and is widely used for DC withstand voltage tests and leakage current tests of electrical equipment. It also specially sets the functions of measuring the voltage U1mA under 1mA of zinc oxide arrester and the leakage current under 0.75U1mA. It is a new high-tech product researched, designed, and manufactured recently, suitable for DC high voltage tests on zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, switches, and other equipment in power departments, factory and mining enterprise power departments, scientific research units, railways, chemical industry, power plants, etc. It is the most ideal replacement product in the new century.

The new generation DC high voltage generator adopts a high-frequency voltage doubling circuit, takes the lead in applying the latest PWM high-frequency pulse width modulation technology, closed-loop adjustment, and uses large voltage feedback to greatly improve voltage stability. It uses high-performance high-power IGBT devices and their driving technology, and according to electromagnetic compatibility theory, adopts special shielding, isolation, and grounding measures. This makes the DC high voltage generator achieve high quality and portability, and can withstand rated voltage discharge without damage.

The main components of the portable DC high voltage generator instrument are selected from advanced technology components from the United States, Germany, Japan, and other countries, making the instrument more reliable and stable. The voltage doubling cylinder is developed and produced with German technology, and the high-frequency transformer is specially designed by experts with small size, large capacity, and strong overload capacity, which is convenient for on-site operation and testing. Looking to the future, we will continue to actively expand the market. With quality and reputation as our life, we will continuously improve our scientific and technological level, develop cutting-edge high-quality products to meet the needs of users, strive to develop, and create new brilliance in the new century.
