高压故障电流限制器应用及研究

指出随着电力工业的迅猛发展及用电规模的不断攀升,导致很多电力节点的短路电流超标,如何限制或快速开断过大的短路电流、保护电力主设备及电网安全成为电力工作者关注的重大问题,故障电流限制器正是解决这一问题的关键设备。阐述了高压故障电流限制器的概念、分类、原理,分析了高压故障电流限制器的发展水平、发展趋势、典型及实际应用情况,表明故障电流限制器的使用在预防变压器损坏事故方面有良好的应用前景。

The Application of High-voltage Fault Current Limiter

With the rapid development of electric power industry and the expansion of power utilization scale,short-circuit current at nodes exceeds standard value.Thus,how to limit or fast cut off the short-circuit current to ensure the security of main equipment and power grid has been an important issue for electric workers.Fault current limiter can solve these problems.This paper focuses on the structure,classification,principles,the development level,development trend and the typical application of fault current limiter which shows better prospect of application to prevent the damage of transformer.
