The utility model provides a solid -state fault current limiter includes current -limiting reactor L1, current -limiting reactor L2, current -limiting reactor L3, thyristor valve T1, thyristor valve T2 and bypass circuit breaker K, current -limiting reactor L1 establishes ties with current -limiting reactor L2 and forms the current -limiting reactor branch road, and thyristor valve T1 and thyristor valve T2 establish ties and form the thyristor valve branch road, and bypass circuit breaker K and thyristor valve branch road are all parallelly connected with the current -limiting reactor branchroad, current -limiting reactor L3 one end and current -limiting reactor L1 and current -limiting reactor L2's mid point, its other end and thyristor valve T1 and thyristor valve T2's midpoint connection. The utility model provides an almost do not have the influence to electric power system when technical scheme can realize normal operating, the automatic conditional short -circuit current in back takes place for the trouble. Just the utility model provides a solid -state fault current limiter requires lowly to trouble recognition speed, simple structure, and nos full -controlled power electronic device, and the accessible changes the big or small individual adjustment of current -limiting reactor to the current -limiting effect of peak value of short circuit current and steady state value, the engineering application of being convenient for.
