变压器运行维护变压器运行维护transformer operation and maintenanceb一Onyaq}yunxlng we{hu变压姗运行维护(transformer operation andmalntenance)电力变压器进行电压变换及能量传翰的工作状态以及在其工作状态或在不工作状态期间所进行的技术处理，以保持其正常的工作状态或消除已基礴出的缺陷。对变压器运行的要求是:安全可靠，高效经济;正常负荷下输出电压保持在规定的范围内;紧急悄况下能按规定的方式超铭牌出力运行。当单台变压器容t不够时，可以采用两台以上并联运行的方式.为实现对变压器运行的要求，有关标准规定了变压器的使用条件、允许温升、超铭牌出力、并列运行、运行监视和维护检修事项。使用条件变压器的正常使用条件为:海拔不超过1。。。m;最高气温十40’C，最高日平均气温+30℃，最高年平均气温+20’C，最低气温对户外和户内分别为一30℃和一5℃;冷却水最高人口温度为+30℃;电压波形近似于正弦波，多相电源电压近似对称。特殊的使用条件下，变压器的额定参数要有相应的改变。例如，当冷却空气温度超过上述正常值，但超过值不大于10℃时，则温升限值按该超过值降低一个相同的值;运行在海拔高度超过l000m的场合，以每500m为一级，温升限值按下列数值减少:油浸自冷式变压器减少2.0%，油浸风冷式及强油风冷式变压器减少3.0%。此外，对十分恶劣的运行条件，例如严重污秽区、地展频发区等，变压器应该有相应的特殊技术条件。允许温升变压器某一部位的温度高于冷却空气温度或冷却水人口温度的允许差值。变压器内部各部位的温升是不相同的.对油浸式变压器，油的温度自下而上逐渐升高，绕组的温度也有同样的变化规律，其温度分布可简化为如图所示:绕组温度和油的温度在垂直方向上按两条平行直线分布，两者之间有一恒定的温度差山;绕组在同一平面上温度也不相同，饼式线圈的绕组中部散热条件较差，因此最热点的温升还会高于该平面上的平均温升值。离度顶娜璐妞一T~最翩平均倪组z，，坟一.一翻一泊一.目一均一阳，一平一日一开 绕组和油的温度分布图变压器绝缘的寿命就是由最热点的温度所决定的。通常的温升试验只能测得变压器上层油温及冷却器各部位的油温，还可用测绕组直流电阻的方法来推算各绕组的平均温度。但最热点的温度是无法用常规的方法侧量的。
