Abstract
A frequency converter includes a storage element for storing electrical energy and a detector connected to the storage element and including a pressure sensor and a temperature sensor. The detector detects a physical variable in immediate vicinity of the storage element and provides a signal in accordance with an electrical resistance of the detector when a predefinable change over time of the physical variable is exceeded, with the electrical resistance representing an output of the detector. A housing encloses or substantially encloses the detector and the storage element. Communicating with the detector is an evaluation facility to detect the predefinable change over time of the physical variable. The evaluation facility and/or the detector is/are connected to a higher-level security system designed to decouple and/or to divert the electrical energy from the storage element when the predefinable change over time of the physical variable is exceeded.
