摘要：
A taped insulation structure is proposed for the cross-linked polyethylene (XLPE) insulated DC cable and the mass-impregnated paper (MI) insulated DC cable. In order to verify the reliability of the structure, the electric field distribution of the joint is calculated by simulation software. The simulation results show that taped insulation material with slightly larger conductivity compared with factory insulation can obviously improve the distribution of electric field at the root of stress cone. When the reverse polarity impulse voltage was applied, the direction of the electric field intensity formed by the reverse impulse voltage was opposite to the steady-state electric field formed by the previous DC voltage, so that the field distortion of the poly tetra fluoroethylene(PTFE) was reduced compared with MI. Considering the electric field distribution of joint under working temperature and technology difficulty of joint manufacturing, PTFE was selected as the taped insulation material and the joint manufactured as the structure illustrated in this paper passed the type testing. © 2019, Harbin University of Science and Technology Publication.
