Integrated air cooling and arc resistant system for medium voltage drive

Conductive elements (A-C) are positioned within a housing () of an electric device. The conductive elements (A-C) are arranged such that in an event of an electric arc () occurring between the conductive elements (A-C) an electromagnetic force is exerted upon plasma of the electric arc () such that the electric arc () is directed towards a wall () of the housing (). Furthermore, a conductor configuration () includes conductors (A,B,C) and sacrificial electrodes (A-C) positioned within a housing () of an electric device, wherein the conductors (A-C) are arranged such that in an event of an electric arc () occurring between the conductors (A-C) an electromagnetic force is exerted upon plasma of the electric arc () such that the electric arc () is directed towards the sacrificial electrodes (A-C).

Arc fault resistant electric equipment

Embodiments include a liquid cooled electronic device including a compartment configured to enclose an electronic module therein.
