Is快速限流器对提高电能质量的应用

基于电压暂降的原因和危害,提出采用主变并联运行的方式降低电源阻抗,减少电压暂降的影响.介绍了Is快速限流器在主变并联运行中的应用及与电抗器的并联应用,解决了开关设备分断容量不够的问题,最后介绍了Is快速限流器设计原理.

Application of Is-Limiter for the Power Quality Improvement

Based on the reason and harm of voltage sag, a mode that main transformer parallel operation was applied to reduce impedance of power supply was proposed to lessen effect of voltag, sag. The application of Is rapid limiter in main transformer parallel operation and in parallel with electric reactor was introduced, which resolves problem that switchgear hasn't enough breaking capability. Finally, the design principle of Is rapid limiter was introduced.
