UHV DC Transformer Field Calibration Platform:

Core technology and innovation points:

1. High-stability DC power supply technology for UHV site;

2. Fully automatic "missile upright" deployment structure, no assembly, no auxiliary equipment, and the test deployment process does not exceed 30 minutes;

3. Intelligent induction hydraulic automatic control buffer technology, the erection process is stable, smooth and safe;

4. Airbag-type metal scale pressure equalizing cover, inflated and formed during the test, and deflated and contracted during storage and transportation (used for 800kV and above):

5. Test platform automatic getting on and off technology;

6. Platform expansion support and automatic leveling technology.

Technical features:

1. Multi-level voltage stabilization, stability is better than 0.03%;

2. Full-wave symmetrical voltage doubling, ripple coefficient is better than 0.1%;

3. Coarse, fine, fine, digital output adjustment, fineness is better than 0.05%;

4. Divided output, the lower limit of reaching the standard is better than 5% of the rated output. Intelligent control, automatic boosting, timing, and pressure reduction:

5. Wheeled traction self-propelled chassis technology (optional);

The pressure doubling/pressure measurement adopts a micro-positive pressure nitrogen insulation structure, which is moisture-proof and non-toxic, safe in storage and transportation, and low in maintenance costs.
