Abstract
A monitored switch gear device that includes a switch gear, a plurality of magnets, a magnetic field sensor and a processing circuitry. The switch gear includes an opening/closing mechanism adapted to selectively open and close an electrical circuit. The opening/closing mechanism includes a pivotally mounted shaft configured to rotate about a pivot axis as the opening/closing mechanism moves between an open and a closed state. The magnets of the plurality of magnets are spaced from each other and fixedly attached to the shaft. The magnetic field sensor senses a magnetic field generated by each magnet of the plurality of magnets as the shaft pivots. Each magnet of the plurality of magnets defines a different angular position of the shaft detected by the magnetic field sensor in which the magnetic field sensor senses a respective magnet of the plurality of magnets. The processing circuitry computes a first angular speed of the shaft based on signals provided by the magnetic field sensor when it senses the magnetic field generated by at least two magnets of the plurality of magnets as the shaft pivots in one direction.
