摘要 主变压器风冷信号是供变电运行和监控运行人员参考的重要信号,由此来确定变压器冷却器的工况。文章针对电力系统中主变压器冷却器信号不能准确反映各组冷却器工况的问题,提出增加测控装置遥信点和运用视觉效果防止主变压器风冷全停的改进方案。改进方案实现强油风冷主变压器冷却器的工况更加详细,有效地防止主变压器冷却器全停和因此而造成主变压器跳闸事故的发生,增强电力系统供电的可靠性。 The air-cooling signal of main transformer is an important reference signal to substation and supervision operators,thereby to determine the conditions of the coolers.Aiming at the problem of cooler signal of main transformer can not accurately reflect the working conditions of each cooler in electric power system,the article presents the improvement solutions of increasing telesignalisation points for measurement and control device and applying visual effect to prevent aircooling full stop.The improved solutions can realize the conditions of forced-oil-air cooling transformer coolers more detailed,effectively prevent the main transformer coolers full stop and tripping accidents,enhance the reliability of power supply.
