I. Characteristics:
1.110KV Series Oil immersed Power Transformer has optimized design using advance technologies in order to offer low noise, low partial discharge, high resistance to short cuircuit capacity. Advance design software are used for electromagnetic calculation and design ensure sufficient safety margin during short circuit period. This is based on in-depth theoretical and experimental studies on magnetic, thermal, mechanical strength and short circuit strength. To ensure reliability of the transformer, the insulation are decided based on calculation of the electric field distribution in inner coils will ensure voltage gradient and at coil end it will ensure low partial discharge.
2. Potential distribution is effectively improved by application sofware to calculate the impact and gradient potential distribution. The potential calculation is also done between various parts of the coil including between the coil and coil and earthing.
3. Low Partial Discharge, improves service life.
4. Low noise
Lower the noise level by choosing high quality steel core material, right flux density and the self-vibration frequency of the core, application of high resistance to short-cuicuit of the body structure,
Improves the connection method of tanl and active part.
5. Low temperature rise
Apply reasonable oil flow distribution structure by calculation of oil flow distribution, reduce the winding hot spot temperature rise and the average temperature rise in order to increase overload of each part, extend the life of transformers.
