摘要
电流互感器是变电站重要的一次设备,它将一次系统的大电流变换成小电流提供给保护、计量、测量、故障录波等设备;运行中的电流互感器若二次侧开路,严重威胁人员和二次设备的安全;快速正确的处理方法可有效降低危害。
Current transformer(CT) is a connection between high voltage grid and its control system, which transforms the currentof high voltage system into a small, measurable current for protection devices, meters, automations and wave-recording devices.Any open-circuit in its secondary windings may leads to the following results: an inductive e.m.f. as high as several k V may occur,endangering staffs who work on the secondary circuits as well as other secondary equipments. If the open-circuit is handled fast inproper way, the damage can be limited to the least.
