1影响线损的主要因素1.1影响线损的技术因素(1)配电网结构的影响。如低压线路供电半径太大,达不到国家电网公司对低压输电半径的技术要求;配电变压器布点不合理,导致配电变压器距离负荷中心较远;电容器以及电缆中的绝缘子使用时间过长;主干线路导线线径小;调压器、消弧线圈以及变压器等设备产生铜损;带电设备绝缘性能不好引起电力泄漏;配电站与变电站中的信号设备、通风设备以及充电装置消耗电力等。
1 main factors affecting the line loss 1.1 line loss affecting the technical factors (1) the impact of distribution network structure. Such as low-voltage line power supply radius is too large, less than the State Grid Corporation of the low-voltage transmission radius of the technical requirements; distribution transformer distribution is unreasonable, resulting in distribution transformer far away from the load center; capacitors and insulators in the cable for too long; The trunk line wire diameter is small; voltage regulator, arc suppression coil and transformer and other equipment copper loss; charged equipment insulation performance is not good cause power leaks; distribution substations and substation signal equipment, ventilation equipment and charging device power consumption .
