摘要
针对变电站直流融冰装置参数工程设计问题,比较和分析不同标准、规范关于融冰电流计算公式的差异,以某 500 kV变电站实际工程直流融冰装置参数设计为例,按照不同计算公式给出了最小融冰电流、最大融冰电流、1h融冰电流、直流融冰压降、直流融冰装置容量等参数计算结果;通过对比分析给出实际工程中融冰装置参数设计公式选用的建议.
Abstract
Aiming at the engineering design of DC ice-melting device parameters in substations,the differences between calculation formulas of ice-melting current in different standards and specifications are compared and analyzed.Taking the parameter design of DC ice-melting device in a 500 kV substation for example,the calculation results of minimum ice-melting current,maximum ice-melting current,one-hour ice-melting current,DC ice-melting voltage drop,DC ice-melting device capacity and other parameters are given.Suggestions for the selection of parameter design formula of ice-melting device in practical engineering are proposed.
