摘要
保持配电变压器的经济运行对于电网节能降损具有重要意义。本文通过计算分析配电变压器损耗率与负载率的关系,找出配电变压器的经济运行区间,并对变压器增容的时机及经济性进行了探讨。以把握配电变压器损耗的变化规律,为合理安排投资、提高投资的经济效益提供指导。
It is important for the energy saving to keep the economic operation of the distribution transformer. Through analyzing the relation between the loss rate and load rate of distribution transformer, the economic running interval of distribution transformer is found out, the opportunity and economy of transformer capacity increase are discussed. In order to grasp the change law- of the distribution transformer loss, provide guidance for reasonable investment and improve the economic efficiency of the investment.
