Sensor assembly, device and method for anticipatory detection of failures in a switch gear caused by contamination and corresponding switch gear

摘要

The arrangement (2) has two sensor units (4a, 4b) provided with conductor units (6a, 6b) that are arranged in parallel and/or at equidistant to one another. The conductor units are connected with one another in an electrically conducting manner, where each conductor unit has an electrically conducting contact surface. The sensor units are arranged in pairs, such that one conductor unit of the sensor unit (4a) is engaged into a distance between the conductor units of the sensor unit (4b) for producing a dovetail connection of the sensor units and for forming a sensor unit-pair. An independent claim is also included for a method for anticipatory detection of failures in a switch gear.
