12月7日获悉,为深化配电网标准化建设,在国网设备部的统一部署下,中国电力科学研究院有限公司近日牵头组织15家省级电力公司、19家国内知名电气设备制造企业联合成立专项攻关团队,启动配电网低压柔性直流开关设备标准化设计工作。
低压柔性直流开关是柔性直流配电网的关键设备,能够快速可靠地开断负荷电流、过载电流及故障电流,保障柔性直流配电网系统安全可靠运行。当前,低压柔性直流开关呈现规模化应用趋势,但由于现有低压柔性直流开关生产厂家多、结构设计差异大、产品质量参差不齐、造价成本高,且国内尚没有相关技术标准,设备选型、后期维修、物资储备等工作存在较多不便。
为此,攻关团队按照“安全可靠、坚固耐用、标准统一、通用互换、合理分级、广泛适用”的原则,重点围绕产品选型原则、典型结构方案、主要接口参数、关键元件配置及试验检测细则,开展配电网低压柔性直流开关设备标准化设计工作,助力提升设备设计通用性及运维便利性,推动配电设备转型升级。
