    Abstract
  •   Introduction  China Fusion Engineering Experimental Reactror （CFETR） aims to demonstrate the engineering feasibility of steady-state combustion plasma. The 110 kV high-voltage power supply and distribution system supplies the superconducting magnet and the reactive power system through cables and other equipment. Therefore, the stable work of the high-voltage cable is very important to the development of the experiment.
      Method  The normal operation of the cable needed to consider the induced potential and circulating current of the metal sheath. In this paper, after fully investigating and calculating the metal sheathing method, it was determined that the 110 kV high-voltage XLPE cable was cross-connected and grounded. Use ANSYS Maxwell to model the three-phase cable, simulate the sheath induced voltage, and finally substitute the simulation results into the equivalent circuit constructed by Simplorer.
      Result  The simulation results show that the induced electric potential and circulating current of the sheath meet the requirements of national standards.
      Conclusion  The cross interconnection grounding scheme designed in this paper for the 110 kV cable sheath is safe and reliable, which can ensure the long-term stable operation of the cable.
