On September 5th, the G20 summit ended in Hangzhou. In just a few days, the summit will merge the traditions of the whole city with reality, and the innovation and classical blending will show the world a colorful and charming Hangzhou. During the period, the power security of the summit is also very important. Here we mainly talk about the safety impact of the three-phase unbalance of the power distribution network on the distribution network transformer.
Influence of three-phase load imbalance of power distribution network on distribution network transformer
1. Three-phase load imbalance will increase transformer losses. Transformer losses include no-load losses and compliance losses. When the three-phase load reaches equilibrium, the loss of the transformer is minimized.
2. Three-phase unbalance can cause serious consequences of burning the transformer. Unbalanced heavy-duty phase current is too large, too much overload, can cause overheating of windings and transformer oil, reduce transformer insulation performance, reduce transformer life, and even burn equipment.
3. Three-phase load unbalanced operation will cause the zero-sequence current of the transformer to be too large, and the temperature of the local metal parts will rise abnormally. In severe cases, the transformer operation accident will occur.
Liths Electric Solution: ACTSine-MO distribution network three-phase unbalanced treatment device
The three-phase unbalanced treatment device of the company’s distribution system ACTSine-MO adopts the main components such as Infineon IGBT and TI DSP of the United States, and realizes the three-phase current imbalance suppression of the whole machine through advanced proprietary patent control strategies and algorithms. Rate >99%. With its unique ultra-quiet design, the Lex ACTSine-MO unit operates at full noise down to 48dB, achieving the industry’s lowest noise levels and completely eliminating user complaints due to equipment noise. In the same new technology products, it enters a stable and reliable long-term operation stage in advance, and adapts to any harsh power supply environment. The Liss ACTSine-MO products have been operating stably and reliably in 12 provinces across the country.
