摘要
基于分形理论对智能漏电保护器关键部件——剩余电流互感器的故障进行分析,根据正常状态与故障状态剩余电流互感器输出波形盒维数之间的关系,研究一种电子式的剩余电流互感器故障自诊断方法,通过实验证明该方法的有效性。实验结果表明:该方法能够准确提取故障特征,并完成剩余电流互感器的故障自诊断,为剩余电流互感器故障诊断提供了新的途径。
Based on the frac tal theory , th is paper analyzes the faultofa residual current tra n s-former？ which is the key component of a leakage protector. A sel--diagnosis m ethod o f the ele c tro n-ic residual current t ransformer is studied b y the re la t io n sh ip of box dimensions o f rent transformer output waveform under th e normal state and the fa u l t state. tiveness of the method is proved b y experiments. The experimental re su lts show th a t th is methodcan accurately extract faul t features and complete faultsel--diagnosis of residual currenttrans fo rmers？ providing a new way for faul t diagnosis o f residual curre nttrans formers.
