电压是衡量电能质量最主要的指标之一,电压偏差对低压用电设备会产生极大的危害,甚至会导致低压用电设备系统的失稳与崩溃。对电压偏差的概念进行阐述,分析民用建筑电气电压偏差如何产生及对用电设备的影响,提出低压系统电压偏差的改善措施,以提高其经济效益和社会效益。
Voltage is one of the most important indicators to measure the power quality. The voltage deviation will cause great harm to the low-voltage power equipment and may even lead to the instability and collapse of the low-voltage power equipment system. The concept of voltage deviation is described. The analysis of how the electrical voltage deviation of civil buildings is generated and the impact on the electrical equipment is put forward. The measures to improve the voltage deviation of low voltage system are proposed to improve its economic and social benefits.
