摘要
直流输电换流变压器的套管SF6密度继电器在运行过程中易出现故障,严重影响电网安全稳定运行。因此,分析SF6密度继电器事故发生的原因,提出将密度继电器移出阀厅并加装四通阀的设计方案,确保换流变压器套管SF6压力在正常范围,保证电网安全可靠运行。
The casing SF6 density relay of HVDC converter transformer is prone to malfunction during operation,which seriously affects the safe and stable operation of power grid. By studying the SF6 density relay the cause of the accident,put forward and remove the density relay valve hall with four-way valve design,to ensure the safe and reliable operation of the power grid,and has significant economic benefits.
