1. A device for testing contents of a switch cabinet after planning-based assembly of technical components (2a-2e) and wiring of the technical components via terminal connections (6) provided for the wiring by means of marked electrical lines (5), the device comprising:
a camera unit (7) for at least two-dimensional image acquisition of the technical components (2a-2e) of the switch cabinet, contents of which are in fully assembled form, wherein the technical components are mounted and wired on a mounting plate (4) of the switch cabinet (1),
an evaluation unit (8) for carrying out a comparison between an image layout (100) of an actual state based on the image acquisition with a provided planning layout (200) of target state, at least with regard to:
a) a completeness and position of the installed technical components (2a-2e),
b) assignment of the terminal connections (6),
c) wiring of the electrical lines (5),
an output unit (11) for providing a test result on structural consistency of the switch cabinet (1) for an assessment with regard to delivery release or fault rectification,
wherein in addition to the structural consistency of the switch cabinet (1), the evaluation unit (8) is also configured to check functional consistency by comparing functionality produced by the technical components (2a-2e) and connection of the technical components via the electrical lines (5) with an electrical circuit diagram (300) associated with the planning layout (200), and
wherein a simulation unit (12) is provided which, on the basis of a positive structural and functional test, is configured to carry out a simulation of various operating states of the switch cabinet (1) over a predefined period of time in order to test temperature development in the switch cabinet under a given load scenario against a corresponding planning specification, thereby providing a quality check to determine whether the switch cabinet contents comply with thermal limit values at the given load scenario.
