Specifically used to detect electrical insulation strength and leakage current of power devices
Integrated dc high voltage generator is a new generation of portable high-voltage detection instrument designed and manufactured according to China Power Industry Standard DL/T848.1-2004 "High-voltage test equipment general technical conditions Part 1: DC Integrated dc high voltage generator". Electrical insulation strength and leakage current of power devices.
The Integrated dc high voltage generator uses a high-frequency voltage doubling circuit, which uses advanced PWM pulse width modulation technology and voltage-current double-closed-loop feedback technology to improve power supply regulation and load regulation, resulting in high voltage stability and low ripple. Use imported high-power IGBT devices and their driving technology to eliminate switching interference and achieve high quality and portability of Integrated dc high voltage generator. The imported high-frequency high-voltage rectifier diode is used to make the double-press cylinder more compact and lighter, and improve the efficiency of the whole machine. According to EMI electromagnetic interference and EMC electromagnetic compatibility theory, measures such as shielding, isolation and grounding are adopted to improve the safety of the whole machine and to withstand the rated voltage discharge without damage. The instrument has complete protection functions, zero protection, over-voltage protection, over-current protection, and breakdown protection. The protection circuit uses nanosecond-level special sensors, which are fast and reliable, and effectively protect people and equipment. The over-voltage setting uses a digital dial switch, which is easy to operate and has high setting accuracy. Add intelligent high-precision 0.75U function button to facilitate the testing of zinc oxide arrester.
Integrated dc high voltage generator adopts integrated design scheme: double pressure cylinder and Host are placed in one chassis, combined with new technology, select new device, realize small size, high power, light weight, convenient operation, safe and reliable, power supply output quality The high advantage is the ideal test instrument for the high voltage test industry.
