水轮发电机组在运行中,引起瓦温上升的原因很多。正确判断瓦温过高原因是解决问题的关键。柴河电站2号机组上导油槽温度及上导瓦温存在过高问题,本文对引起上导瓦温过高的原因作了分析,并以柴河电站2号机组为例,详细阐述了上导油槽温度及上导瓦温偏高的原因及处理方法。 Water turbine generator in operation, causing the rise of the tile temperature for many reasons. Correct judgments on the reasons for the high temperature is the key to solve the problem. The temperature at the sump of No.2 Unit of Chaihe Power Station and the overheating of the upper guidewaters are too high. This paper analyzes the reasons that cause the overheating of the upper guidewaters. Taking the No.2 unit of Chaihe Power Station as an example, The reason of the temperature of the oil sump and the high temperature of the upper guide shoe and the treatment method.
