摘要
光纤电流互感器的应用显著改善了继电保护动作的准确性。光纤电流互感器在变压器差动保护的应用,从根本上解决了电磁感应式电流互感器磁饱和造成的差动保护误动作,并使得励磁涌流的暂态保护可以得到实际应用;最后讨论了光纤电流互感器对变压器差动保护的其他影响。
Optic fibre current transducer application improves greatly the accuracy of relay protection.Its application in differential protection of transformers resolves the false action problem of differential protection caused by magnetic saturation of electromagnetic current transducers at root,makes transient protection of excited inrush practical.In the end,the other influences of optic fibre current transducer on differential protection of transformers are discussed.
