1、 Product Overview:
The DC high voltage generator is a new generation portable high voltage testing instrument designed and manufactured according to the Chinese new power industry standard DL/T848.1-2004 "General Technical Conditions for High Voltage Test Equipment Part 1: DC High Voltage Generator", specifically used to test the electrical insulation strength and leakage current of power devices.
stem or root of plantsDC high voltage generatorAdopting high-frequency voltage doubling circuit and applying new PWM pulse width modulation technology and voltage current dual loop feedback technology to improve power supply regulation and load regulation, resulting in high voltage stability and low ripple. Using imported high-power IGBT devices and their driving technology to eliminate switch interference and achieve high quality and portability of DC high-voltage generators. The use of imported high-frequency and high-voltage rectifier diodes makes the voltage doubler more compact and lightweight, improving the overall efficiency of the machine. According to the theories of EMI electromagnetic interference and EMC electromagnetic compatibility, measures such as shielding, isolation, and grounding are adopted to enhance the safety of the entire machine and enable it to withstand rated voltage discharge without damage. The instrument has complete protection functions, including zero protection, overvoltage protection, overcurrent protection, and breakdown protection. The protection circuit uses nanosecond level dedicated sensors to quickly, reliably, and effectively ensure personal and equipment safety. The overvoltage setting uses a digital dip switch, which is easy to operate and has high setting accuracy. Adding an intelligent high-precision 0.75U function button is beneficial for testing zinc oxide lightning arresters.
