Intrinsically safe energy transmission unit for supplying an electrical device with increased power

Abstract

A safe energy supply unit () and system, for supplying an electrical device () in an explosion-proof area, transmits power from an energy source (), including a plurality of galvanically isolated individual sources, with a multiple line connection () with a plurality of galvanically isolated and individually shielded conductor pairs (). A collector device (), in an explosion-proof jacket () at an end of the multiple line (), has uncoupling devices () for the galvanically isolated conductor pairs and a combiner circuit () that combines the transmitted electric power from each line into a global power. The global power is outputted at an output () of the collector device to the electrical device. The conductor pairs allow for an increased global power, which is scalable, safely transmittable, with standard, conductor pairs. The electrical device is intrinsically safely supplied with high power with minimal effort.
