The product has the characteristics of compact structure, low loss, low noise, energy conservation and environmental protection. Reduced the empty load loss of the product, improved capacity utilization, and achieved significant energy-saving effects.
Product Description
In response to the demand of China Railway Corporation for energy-saving products, the company has developed a new type of energy-saving autotransformer. This product has passed various test indicators of the National Transformer Inspection and Testing Center in one go: the no-load loss of the same capacity autotransformer has decreased by 28.5% and the load loss has decreased by 23.4% compared to the current operation. It has been determined as the first energy-saving product (set) in China and the first set of technical equipment in Shandong Province, and has passed the national new product appraisal. The appraisal committee unanimously believes that the overall technical indicators of this product have reached the forefront level and can be promoted for use. The product has now been connected to the grid for power transmission at the Jiaogezhuang AT station and the Pingdu North section station of the Weilai high-speed railway.
Product features
The product has the characteristics of compact structure, low loss, low noise, energy conservation and environmental protection.
1. Reduced the empty load loss of the product, improved capacity utilization, and achieved significant energy-saving effects.
2. Adopting advanced technology, the oil flow speed is accelerated, the heat dissipation efficiency is improved, the temperature rise is effectively reduced, and the overload capacity is improved.
3. Improved short-circuit resistance, reduced short-circuit impedance, greatly increased terminal voltage of the line, reduced and mitigated the impact of short-circuit point power, and ensured the operation of the transformer.
