摘要
笔者针对变压器的试验信息,分析了影响变压器剩余寿命评估的因素,确立了用于变压器剩余寿命评估的信息量。根据已有的研究成果,结合健康指数公式,推导并建立了依据当前信息所反映出的变压器状态的健康指数、剩余寿命计算公式,结合实例,应用所建立的模型对变压器的健康指数、剩余寿命进行分析和计算,经验证评估,结果与设备的实际情况相符。
The factors affecting transformer remnant life estimation are analyzed in view of the transformer testing data. On the basis of the established information for remnant life estimation of power transformer, a formula which reflects transformer's health condition and remnant life is deduced according to the current information. The model is applied to calculate the health index and remnant life of a transformer. Estimation result shows consistency with the practical condition of the transformer.
