External Force Damage Detection Method of Buried Cable Based on Optical Fiber Sensing Technology

The safe and stable operation of high-voltage buried cable plays an important role in the development of energy. The damage of cable is mainly caused by external force. Aiming at the method of online monitoring of high-voltage buried cable operation by distributed optical fiber sensor, the XLPE high-voltage buried cable model is established by using optical fiber sensor technology and finite element software ANSYS, and the simulation analysis of buried cable damaged by external force is carried out, The change of internal physical quantity can provide reference for distributed optical fiber sensor to monitor the operation status of high voltage buried cable online.
