摘要
在220 kV及以上的超高压输变电工程中,随着OPGW、ADSS等光缆在输电线路中的使用,光纤电流差动保护因其保护原理简单、动作快速、不受串补影响、能可靠地反应线路上各种类型故障等优点,作为超高压线路主保护之一得到了越来越广泛的应用。
In the UHV transmission and transformation project of 220 kV or above, along with the usage of OPGW and ADSS optical-fiber cable, the optical fiber differential protection which has the merit such as simple principle, fast action, not to be affected by series compensation, reliably responding every type of fault on line becomes more and more widely used as one of the main protections for UHV lines.
