摘要
根据图纸对某特高压站 1000 kV变压器采用的强迫油循环风冷(OFAF)的冷却方式进行分析,研究的主要内容包括电源切换回路、风冷控制回路、风冷全停跳闸回路,并且针对该风冷系统可能存在的缺陷进行改进,增加了电压监视部分,改进后可降低风冷系统运行过程中发生故障所带来的风险.
Abstract
Forced oil and forced air(OFAF)cooling mode used in the main substation of UHV substation is analyzed ac-cording to their drawings.The main contents include the power supply switching circuit,the cooling system control loop and full stop tripping circuit. Considering the problems which may happen while the system is operating,the improvement of the circuit in this cooling system is also mentioned in this paper.
