电气节能的技术措施主要有以下四个方面(建议):1供配电系统节能1)准确计算负荷容量,合理设计供配电系统,实现供配电系统和用电设备的经济运行。2)合理设置变电所(深入负荷中心),用电负荷的低压供电半径控制在250m以内,减少线路损耗。3)按变压器经济运行条件,合理选择变压器的容量和台数,变压器负荷率控制在70%~85%范围内。变压器采用低损耗、低噪声节能型变压器。季节性负荷较大时,设置专用变压器。4)无功功率补偿采用集中补偿和分散就地补偿相结合的方式,变电所采取低压集中补偿方式,补偿后的功率因数不
The technical measures for electrical energy saving mainly include the following four aspects (suggestions): 1. Energy-saving for power distribution system 1) Calculate the load capacity accurately, rationally design the power supply and distribution system, and realize the economic operation of power supply and distribution system and power consumption equipment. 2) Proper setting of substation (depth load center), the low-voltage power supply load of the load control within 250m, reducing line losses. 3) According to the economic conditions of the transformer, a reasonable choice of the capacity and number of transformers, transformer load factor control in the range of 70% to 85%. Transformer low-loss, low-noise energy-saving transformers. When the seasonal load is large, set up a special transformer. 4) Reactive power compensation adopts the combination of centralized compensation and decentralized on-site compensation. Substation adopts low-voltage centralized compensation mode, the compensated power factor is not
