Device for monitoring and controlling switching devices and combinations of switching devices

Abstract

Abstract Devices for monitoring and controlling switchgear to determine the required maintenance dates usually operate on a mechanical or time basis. Electronic devices are limited to counting the switching cycles and comparison with stored reference values. In order to achieve maintenance or inspection appropriate to the actual state of the switchgear, the events actually occurring and the instantaneous state of the switchgear are recorded by a multiplicity of sensors (1 to 13) and fed as signals to an evaluation logic (14) which carries out a correlation, an assessment and a comparison with stored behaviour patterns (16) and acts on an optical and/or acoustical indicating device (17) or makes a record in a scannable memory (15). <IMAGE>
