UHV(W) Series No Partial Discharge Variable Frequency Power Supply

1. The equivalence of the experiment is good. The output of this device is a sine wave with low waveform distortion. The waveform distortion rate is less than 3%, which is different from other types of variable frequency power supply devices (other types of variable frequency power supply devices output square waves, which are shaped into sine waves). So, during the testing process, this device does not need to measure peak values.

2. By using fiber optic control, the high and low voltage control circuits are completely isolated.

3. Small size, light weight, flexible handling, very suitable for on-site use.

4. The operation is simple and convenient, the wiring is simple, and it can improve work efficiency by 50% (compared to the generator set method).

5. Safe and reliable, this device integrates multiple protections. Including: discharge breakdown protection, overvoltage setting protection, output short circuit protection, startup zero position protection, bridge arm amplification circuit protection, power curve protection, etc. When any type of protection occurs, the device immediately disconnects the test voltage output, cuts off the main circuit power supply, and ensures the safety of the test personnel, test subjects, and test system.

6. The signal source in this device is generated by a dedicated chip and controlled by a microcomputer. The output frequency is highly stable and can reach 0.01Hz.

7. The variable frequency output voltage is controlled by TI's high-speed microcomputer, and the instability of the output voltage is less than 1%.
