摘要
110kV瑞金变采用了一种利用电弧光信号和主变二次侧电流作为判据的保护系统,动作快速可靠,简单实用,为中低压母线保护提供了一种可借鉴方案。
The arc signal and main substation secondary current had been used as the criterion for the protection system in 110 kV Rui- jin substation, which was fast, reliable, simple and applicable and provided a reference for middle and low voltage bus protection.
