| Abstract: | This paper introduce the quench protection system applied in 2MJ SMES. This quench protection system adopt digital quench detection system and rely on high-powered NI-6224 digital acquisition card, so it can quickly and reliably detect quench in SEMS; Discharge energy circuit adopting alterable discharge energy resistance greatly improve discharge efficiency and reduce volatilization of cooling medium. |
