摘要
20 kV等级配电网在增大输送容量、降低网损等方面效益明显,在原有10 kV配电网基础上推行20 kV电压等级,需对相应设备进行改造。以嘉兴电网为例,对220 kV,110 kV主变及10 kV配变20 kV电压等级改造进行了探讨,提出了改造方案及相应技术措施。
20 kV distribution network is of obvious benefit to increasing transmission capacity and reducing power loss in the grid.Retrofit of relevant equipments is required for promotion of 20 kV voltage grade based on the existing 10 kV distribution network.This paper discusses the retrofit of 20 kV voltage grade of 220 kV and 110 kV main transformers as well as 10 kV distribution transformers illustrated with an example of Jiaxing grid and puts forward the retrofit plan and relevant technical measures.
