Crossed interconnection cable sheath circulation calculation method and device, electronic equipment and medium

The invention discloses a cross interconnection cable sheath circulation calculation method and device, electronic equipment and a medium. According to the crossed interconnection cable sheath circulation calculation method, when the crossed interconnection cable metal sheath circulation is calculated, the influence of the leakage current in the wire core is considered, the sheath circulation on each crossed interconnection section is accurately obtained, the actual operation condition is better met, and the cable can be conveniently monitored and protected. In order to obtain the continuous distribution condition of the sheath current on the line of the sheath loop, the Pi-type equivalent circuit between the wire core and the sheath is infinitesimal, then the distributed equivalent circuit is obtained, and the similar calculation is carried out, so that the distribution condition of the sheath circulating current on each crossed interconnection section is more accurately obtained, and the cable is convenient
