目前全国能源十分紧张,然而能源浪费也十分惊人。节约能源,加强能源管理,是当前一项重要任务,电能尤其如此。加强电能的基础工作,是电能平衡的测算。第一篇全面地介绍在这一工作中所涉及的照明、电动机、线路、变压器等用电设备,线路电能损耗、工作效率等参数的计算公式,以便从中查找电能浪费的原因以及电能节约的潜力。本文介绍了(一)照明;(二)异步电动机输入电功率近似计算;(三)异步电动机负荷的精确能量平衡计算。
At present, the national energy is very tense, however, energy waste is also very alarming. To save energy and strengthen energy management is an important task now, especially for electricity. To strengthen the basic work of electrical energy, is the calculation of electrical energy balance. The first comprehensively introduces the calculation formulas for lighting, motors, lines, transformers and other electrical equipment, line power loss, work efficiency and other parameters involved in this work so as to find out the causes of power waste and the potential for power conservation . This article describes the (a) lighting; (b) induction motor input power approximate calculation; (c) asynchronous motor load accurate energy balance calculation.
