摘要
通过对电网运行经济性和合理性的分析,论述了电网电压等级选择的主要原则,即遵循“几何均值”规律和“舍二求三”原则。提出较为完善的两个电压等级序列。在现行电压等级序列基础上,针对城网和农村电网指出了简化电压等级的目标。
In this paper, the main principle selecting the voltage grade of the electric network is expounded and proved by means of analysis about economical and rationality of the operating electric network, namely the law of 'geometricmean'and the principle of 'abandoning two and seeking for three'are followed. Two voltage grade being perfected comparatively are put forward. On the basis of current voltage grade order the goal that voltage grade is simplified is pointed out being aimed at the urban or rural electric network.
