配电电力变压器的选择
Selection of Distribution Power Transformer
口诀:电力变压器选容量,总用电设备承同时率。再除功率因数和效率。
Tips: Selecting capacity of power transformer and carrying rate of total power equipment. Then divide the power factor and efficiency.
说明:总用电设备是指工厂所有设备功率之和,同时率是指同时间投入运行的设备实际容量与用电设备容量的比值,一般选约为0.7
Description: Total electrical equipment refers to the sum of all the power of the plant equipment, and the simultaneous rate refers to the ratio of the actual capacity of the equipment in operation at the same time to the capacity of the electrical equipment, which is generally selected to be about 0.7.
功率因数:一般选0.8-0.9
Power factor: generally 0.8-0.9
效率:一般为0.85-0.9
Efficiency: generally 0.85-0.9
电力变压器容量=用电设备总容量×同时率/用电设备的功率因数×用电设备效率
Power Transformer Capacity = Total Capacity of Electric Equipment *Simultaneous Rate/Power Factor of Electric Equipment *Efficiency of Electric Equipment
