Abstract

To understand the ampacity and the accident causes of flame-proof high-voltage cable connectors

LBG1-200/6 high voltage cable connector is taken as an example. The structure and material of the connector are introduced from the aspects of electrical

insulation and thermal properties. A coupling model of electromagnetic field and thermal field of the cable connector is established via the finite element method to obtain and analyze the temperature distributions in different atrocious environments. And the additional temperature rise and ampacity change

which are caused by power harmonic

dielectric loss and slight structure change

are quantitatively analyzed by way of example. This study may benefit safe application of the mining cable connector.
