Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0022] like figure 2 As shown, the specific embodiment 1 of the present invention is a single-phase short-circuit fault current limiter. The single-phase short-circuit fault current limiter includes a first reactor L1, a second reactor L2, a double split reactor M, a capacitor C and a switch K. Wherein, the double-split reactor M is composed of a first winding L01 and a second winding L02.
[0023] After the first winding L01 of the double-split reactor M is connected in series with the switch K, it is connected in parallel with the second winding L02, and then connected in parallel with the capacitor C. This parallel circuit is connected in series with the second reactor L2, and the entire series-parallel circuit is connected with the first reactor L1 in parallel. Among them, one end of the first reactor L1 and one end of the second reactor L2 a...
