摘要
对特高压直流系统运行方式转换过程中起关键作用的金属回线转换开关(MRTB)和金属回线开关(MRS)的控制保护策略进行研究分析,重点梳理了避雷器能量限制功能对开关控制的影响,并针对性地提出其在运行中存在的风险和预控措施,以指导现场MRTB和MRS的运维工作。
Metal return transfer breaker（MRTB）and metal return breaker（MRS）play a key role in the conversion process of operating modes in UHV-DC system.This paper analyzes the control protection strategies of the two switches,focusing on the influence of energy limit function of arrester on switch control.The risks and pre-control measures in operation are also put forward,so as to guide the on-site operation and maintenance of MRTB and MRS.
