High-precision transient recording type fault indicator

The utility model provides a high-precision transient wave recording type fault indicator, which comprises a shell, a cover shell hinged to the top of the shell, two groups of springs I fixedly arranged at the top in the cover shell, fixing plates fixedly connected to the bottom ends of the two groups of springs I respectively, and insulating arc-shaped plates fixedly arranged at the bottoms of the fixing plates, and two fixing blocks are oppositely and fixedly installed at the inner top of the cover shell, first semicircular magnetic blocks are fixedly installed at the bottoms of the two fixing blocks, and the two fixing blocks are located between the two first springs. The gap between the shell and the cover shell is placed on a cable, the cable is located between the shell and the cover shell, the cover shell is pressed downwards, an insulating arc-shaped plate makes contact with the cable, two first springs are linked to contract, the purpose of low-stress line pressing is achieved, the situation that the
