摘要
电力系统中所有的电气设备,包括照明灯具都规定有一定的工作电压和频率。电气设备在其额定电压和频率下工作时,其综合经济效果好;但若电压偏高,其使用寿命将大大缩短,而且浪费电能。
All electrical equipments in power system, including lighting, provide a certain degree of operating voltage and frequency. Electrical equipment remains its overall economic effect as it works at its rated voltage and frequency. However, if it works at a bit higher voltage, its life will be significantly shorter, and there will be a waste of energy.
