HUAYI - Model ZGS-120KV -DC Hipot Generator Tester for High-Voltage Testing
The ZGS-DC Hipot Generator Tester by HUAYI is engineered to execute high-voltage testing with precision. Utilizing a high-frequency voltage doubling circuit combined with the latest PWM technology and closed-loop feedback systems, this tester ensures stable voltage levels and minimal ripple. It incorporates advanced IGBT devices to eliminate switching interference, and employs shielding, isolation, and grounding measures to enhance safety and reliability. Imported high-frequency diodes contribute to a compact design, optimizing efficiency. Its comprehensive protection functions include zero, over-voltage, overcurrent, and breakdown protection, utilizing nanosecond special sensors for swift action. Designed with a high-precision 0.75U1mA function, it is particularly well-suited for zinc oxide arrester tests. The unit supports intermittent operation under rated load and has an overload capacity of 10% greater than the rated voltage for 10 minutes, accepting AC220V ±10% 50HZ power input.
DC hipot tester adopts a high-frequency voltage doubling circuit, using the latest PWM pulse width modulation technology and the voltage and current double closed-loop feedback technology to improve the power supply adjustment rate and load regulation rate, making voltage more stable and ripple smaller. Using imported high-power IGBT devices and their driving technology to eliminate the interference of the switch. According to EMI electromagnetic interference and EMC electromagnetic compatibility theory, shielding, isolation, and grounding measures are adopted to improve the safety of the whole machine, and can withstand rated voltage discharge without damage. The selection of imported high-frequency high-voltage rectifier diodes makes the cylinder more compact and lightweight, to enhance the efficiency of the whole machine.
The Instrument protection function is complete, with zero protection, over-voltage protection, overcurrent protection, breakdown protection, protection circuit selection of nanosecond special sensor, and quick and reliable action, effectively protecting the safety of personnel and equipment.
