Zusammenfassung: | The invention discloses a cable metal sheath circulation calculation method considering a cable laying arrangement form, relates to a cable circulation calculation method, and aims to solve the problem that a calculation result is inaccurate due to the fact that a laying mode is not considered in an existing cable circulation calculation method. The method comprises the following steps: establishing a mathematical model of the crossed interconnection cable based on a physical model; segmenting the cable in combination with the actual laying condition of the cable to obtain the length of each segment of the cable under different laying conditions; simplifying the established mathematical model of the crossed and interconnected cable according to the length of each section of cable under different laying conditions to obtain a simplified mathematical model; constructing a circuit by using the obtained simplified mathematical model to obtain an equivalent circuit diagram; and according to the obtained equivalent |
