Abstract
The present invention relates to a work machine, in particular to a construction machine and/or mining machine such as a crawler-type vehicle, a dump truck, mining device or the like, having an electric drive which comprises power electronics which have at least one transformer which has power connections covered by a cover for connecting power cables, wherein a manually actuable grounding device is provided for the all-pole grounding of the transformer and/or for short-circuiting an intermediate circuit connected thereto. The invention in this respect in particular also relates to such a transformer. In accordance with the invention, the manually actuable grounding device is coupled to a cover latch of the cover such that the cover can be unlatched by actuating the named grounding device.
