The analysis of energy saving transformer with variable energy saving effect evaluation efficiency considering the typical load characteristic

New type energy saving distribution transformer has been paid to much more attention of energy saving and environmental protection performance of distribution network, area load characteristic of diversification is the key to energy saving with variable comprehensive performance evaluation factors. For life cycle assessment of energy saving with comprehensive performance and energy saving effect, this paper combined with the performance characteristics of energy saving with variable, on the basis of typical region, city, the nature of the load, the three angles of rural electrified wire netting, from A⁺, A, B, C, D five categories in the load area to select the typical distribution area, classifying the load characteristics research and summary analysis, aimed at no-load loss and load loss, operation efficiency, such as key performance indicators, energy saving effect evaluation of energy saving with variable, for energy saving with variable selection, replacement, comprehensive performance assessment and provide A theoretical reference and method of economic operation support.
