摘要
介绍了南方电网系统换流变压器典型的冷却方式,通过实例分析了换流变压器冷却系统的常见故障,针对交流电源自动切换回路、回检告警回路、电源电压监视继电器和控制柜设计的薄弱环节和存在问题,提出了改进措施,提高了供电可靠性,增强了系统抗干扰能力和冷却器全停故障甄别能力。
This paper analyzes a typical cooling method of conveller transformer in China Southern Power Grid. Through real case studies, weak links and problems are noted in automatic AC power switching, cheek-baek and alarm circuit, line monitoring relay and control cabinet. Meanwhile, corresponding improvement suggestions are provided, which can improve the reliability of AC power, enhance anti-interfereuee ability and capacity on the identification of all-cooler-off fault.
