摘要
随着电力系统负荷增长及分布式电源大规模并网,10kV配电网面临供电连续性与运行安全性双重挑战。环网柜承担着配电网环网供电、负荷切换及故障隔离功能,选型合理性影响配电系统运行效率与可靠性。传统选型标准聚焦额定参数匹配,忽视绝缘介质与运维特性系统性影响。文章围绕10kV配电网环网柜选型展开研究,从结构类型、技术参数及运维特性3个维度,分析选型对供电连续性、稳定性、故障处理效率及运行安全性的影响机理,以期为相关人员提供理论参考。
With the growth of power system load and the large-scale grid connection of distributed power sources,the 10kV distribution network is facing dual challenges of power supply continuity and operational safety.Ring main units undertake the functions of ring network power supply,load switching and fault isolation in distribution networks.The rationality of their selection affects the operational efficiency and reliability of the distribution system.The traditional selection criteria focus on the matching of rated parameters while neglecting the systematic influence of insulating media and operation and maintenance characteristics.This article conducts research on the selection of 10 kV distribution network ring main units,analyzing the influence mechanism of selection on power supply continuity,stability,fault handling efficiency and operational safety from three dimensions:structural type,technical parameters and operation and maintenance characteristics,providing theoretical support,in order to provide theoretical reference for relevant personnel.
