电压、频率和波形是衡量电力系统电能质量的三要素。电压作为三要素之首,标志着电压质量在用电设备的安全经济运行中所起的作用。 用电设备理想的工作电压是其本身的设计额定电压。由于受农村季节性用电及电网负荷利用率等条件所限,在农网中,电压偏移现象时有发生,电力部门通过及时调整负荷和调整电压加以控制,如若不然,低劣的电能,使用电设备不能正常运行,这将给用户造成生产和生活上的损失。容许电压偏移的标准是有限度的,是根据用电设备对电压偏移的敏感性及电压偏移对用电设备所造成的后果严重性而定。根据
Voltage, frequency and waveform are three elements that measure the power quality of the power system. Voltage as the first of three elements, marking the voltage quality in the safe operation of electrical equipment economy plays a role. The ideal operating voltage of electrical equipment is its own design rated voltage. Due to seasonal power consumption in rural areas and grid load utilization and other conditions, in the rural power grid, the voltage offset occurs from time to time, the power sector by adjusting the load and adjust the voltage in time to be controlled, otherwise, inferior energy use Electrical equipment can not operate normally, which will cause loss of production and life to users. The allowable voltage offset criteria are limited, depending on the sensitivity of the powered device to voltage excursions and the severity of the consequences of the voltage offset on the powered device. according to
