摘要
海上风电变压器建造成本高、维护难度大、更换周期长,一旦发生故障,将造成巨大的经济损失和广泛的社会影响。传统的变压器状态评估方法包括化学手段和物理手段,通过对设备的一些物理化学参量推断设备运行状态。近些年的研究表明频域响应测量具有现场抗干扰能力强、能够区分油与纸的状态、且富含绝缘信息丰富等优点,可应用于变压器等设备的状态评估中。因此,探索频域响应测量参数与油纸绝缘系统状态的对应关系对变压器状态评估具有指导意义。
The offshore wind power transformer is characterized by high value and difficult maintenance while the replacement cycle is long.Transformer failure will cause huge economic losses and a wide range of social impacts.Traditional test methods assess transformer condition through physical and chemical parameters.In recent years,research indicated that frequency response has strong on-site anti-interference ability,distinguish the state of oil and paper,and is rich in insulation information,which can be applied to the status assessment of transformers.Therefore,it has bright future in transformer condition assessment by studying the corresponding relationship between the frequency response parameter and state of oil-paper insulation system.
