变压器因自身的总功率损失和阳光照射,常出现较高的线圈温度(同时反映较高的油温),这往往使设备达不到铭牌输出功率。如要超过铭牌的输出功率勉强运行,则可能导致加速绝缘老化甚至损坏。曾因变压器问题影响了发供电。例如,玉林潘岭变电所主变 Transformers often experience higher coil temperatures (also reflecting higher oil temperatures) due to their total power loss and sun exposure, which tends to keep the device from reaching the nameplate output. Reluctance to run beyond the output power of the nameplate can result in accelerated aging of the insulation or even damage. Transformer problems have affected the power supply. For example, Yulin Panling substation main transformer
