The invention discloses a ring main unit intelligent control system which comprises an AC/DC converting unit, a current detecting unit, a state detecting unit, an FTU, a storage battery unit, a normally-opened switch and a switch control unit. The AC/DC converting unit is connected with the alternating current; the AC/DC converting unit, the current detecting unit, the state detecting unit, the FTU and the switch control unit are sequentially connected with a terminal switch; the storage battery unit is respectively connected with the normally-opened switch and the switch control unit; the normally-opened switch is connected with the connecting ends of the current detecting unit and the state detecting unit; the switch control unit is respectively connected with the current detecting unit and the normally-opened switch. According to the ring main unit intelligent control system, the function that a storage battery supplies power under unforeseen circumstances is added so that the stability and the safety of electricity supply are improved, and meanwhile basic control over a ring main unit is achieved on the basis of the low cost and the simple structure.
