Brief Introduction
SXBZ series DC high-voltage generators use high-frequency voltage
doubler circuits, apply advanced PWM high-frequency pulse width
modulation technology, closed-loop adjustment, and use large
voltage feedback to greatly improve voltage stability. Use
high-performance IGBT devices and driving technology with excellent
performance, and adopt special shielding, isolation and grounding
measures according to the theory of electromagnetic compatibility.
The DC high voltage generator has realized high quality, portable,
and can withstand rated voltage discharge without damage. It has
the characteristics of large output power and small volume,
reliable overvoltage, overcurrent and zero-position closing
protection functions, with a voltage switching function of 0.75
times. Mainly applicable to power sector, industrial and mining,
metallurgy, iron and steel and other enterprise power departments
to conduct DC withstand voltage test or DC leakage current test on
high voltage electrical equipment such as zinc oxide arresters,
power cables, transformers, circuit breakers and generators.
Features
- The DC high voltage generator has a small ripple coefficient,
stable and reliable voltage output, no noise, and good reliability.
- With over-voltage, over-current, zero-voltage start-up and fault
protection functions, the voltage protection value can be set and
displayed intuitively.
- Digital display of voltage and current, and readings when power is
on, which is convenient for monitoring the output status.
- With a voltage conversion of 0.75 times, convenient for testing
zinc oxide lightning arresters.
- Compact product structure, small size, easy to carry.
