摘要
分析了市域线区间内电动机负荷采用AC 0.69 kV(660 V)供电的可行性与经济性.AC 0.69 kV(660 V)为规范规定的标准电压,低压相关元器件均可在 0.69 kV系统中正常运行,其实际运用案例在我国工业领域已数不胜数.研究表明,AC 0.69 kV应用于市域线电动机配电领域是可行的;可选择合适的负荷,由AC 0.69 kV供电,其他负荷的配电方案可按常规的AC 0.4 kV方式供电,2 种方案可并行;各市域线项目应根据工程投资估算确定远距离电机配电方案.当负荷的距离及容量合理时,AC 0.69 kV可显著减少工程的总投资.
Abstract
Analyzed the feasibility and economy of using AC0.69kV(660 V)power supply for motor loads in urban line sections.AC0.69kV(660 V)is the standard voltage specified in the specification,and low-voltage related components can operate normally in the 0.69 kV system.Its practical application cases in China′s industrial field are countless.Research has shown that the application of AC 0.69 kV in the field of urban line motor distribution is feasible.Suitable loads can be selected,powered by AC 0.69 kV.The distribution scheme for other loads can be powered by the conventional AC 0.4 kV method,and two schemes can be parallel.Each city line project should determine the long-distance motor distribution plan based on engineering investment estimation.When the distance and capacity of the load are reasonable,AC 0.69 kV can significantly reduce the total investment of the project.
