摘要
由于换流阀水路冷却系统渗漏而引起现场强迫停运事故屡有发生,对电网安全、稳定运行产生了较大影响。为了减少换流阀水路冷却系统渗漏概率,重点分析换流阀渗漏的原因,并提出了相应的防渗漏设计和防渗漏工艺措施,确保了换流阀长期可靠、稳定运行。
Because of the converter valve leakage of water cooling system, it causes the filed forced outage accidents occurred frequently, and influences the security and stability of power grid operation. In order to reduce the leakage probability of water cooling system, focus on the analysis of the reasons for the leakage of the converter valve. Put forward the corresponding anti-leakage design and anti-leakage technology measures, and then ensure the long-time reliable and stable operation of converter valve.
