Calculation and Optimization of Cable Connector Electric Field Intensity in High Speed Rail Based on Finite Element

Abstract:

When high speed rail run at high altitudes, over-voltage occurred in the process of operating makes the air gap of cable connector breakdown. It is necessary to clear the electric field intensity distribution and its numerical size of cable connector to make an optimization in order to curb this phenomenon. For this reason, 1:1 finite element model is established by the use of ANSYS software, and the simulation results show that the maximum value of the electric field intensity of cable connector can reach 644.05 kV/m. The maximum electric field is reduced with adding an insulating jacket to the head of cable connector. When the thickness of the insulating jacket is respectively 3 mm, 5 mm, 7 mm, 10 mm, the maximum electric field intensity percentage decreased is 10.26%, 11.4%, 16.1%, and 16.7%. So the insulating jacket would be an effective measure to inhibiting the breakdown of the air gap at the cable connector.
