农村中小型老旧变压器更新换代及增容改造

The update and capacity increased of old medium and small distribution transformers in rural area

根据有关资料的估算：从发电到供电，一直到用电的过程——广义电力系统中的各种电气设备（包括发电机、变压器、电力线路、电动机等）电能消耗约占发电量的28％～33％。这对全国来说一年就有3178亿kW·h～3746亿kW·h的电能损耗在运行的电气设备中，相当于10个中等用电量省的用电量之和。这说明节电潜力非常之大，但也说明我国电网线损率过高，是世界上产值落后之国。

Based on the assess of correlative data, the process from generating electricity to power supply-energy wastage of diversified electric facility in generalized electric power system（ including generators, transformers, electric power lines, motors and so on） is 28% - 33% in all generation. Every year, about 317.8 - 374.6 billion Kwh is expended in various electric facility all over the country, this is summation of ten medium electro-quantity province. It indicates that electric saving has great potential, at the same time, it also indicates that the line loss of the state grid is at a high level, so the country is one of low production value countries.
