监视水轮发电机组的瓦温,是关系机组能否正常运行的重要项目。监视轴承的温度一般都用温度继电器测量瓦温上限值的方法,但在轴承出现异常苗头、瓦温产生急剧变化时,用这种方法是测不出来的,因为当继电器动作时,轴承也已接近烧损状态。为了克服以上缺点,尽早发现轴承异常,必需对轴承的有关 Watching the temperature of the turbine generator unit is an important project that relates to the normal operation of the unit. The temperature of the bearing is usually monitored by the temperature relay method of measuring the upper limit of the watt-hour temperature. However, when the bearing is abnormal and the temperature of the watt-hour changes drastically, this method can not be measured because when the relay operates, the bearing Burned close to the state. In order to overcome the above shortcomings, early detection of bearing abnormalities, the bearings must be related
