This series of 20kV and 35kV non-excitation voltage regulating dry-type transformers are low-loss products, complying withtherequirements of national standards GB1094, GB/T10288 and IEC726, and have the following characteristics:
1. High performance, low loss, 10(13)Replacement products of model series,2. Use high-quality sicon steel sheets to significantly reduce the magnetic flux density, reduce the magnetostriction of the silicon
steelsheets during operation, and effectively reduce noise.
3. Optimize the high-voltage coil sructure, improve the distribution of interlayer voltage and capacitance, greatly improvetheproduct's ability to withstand the impact of atmospheric overvoltage and operating overoltage, and also improve theelec-tric field distribution, further reducing the product's partial discharge.
4. The temperature control system and air cooling device can be conigured to automatically stat the fan cooling device when theload istoo large, effectively improving the overload capacity of the equipment.
