For detecting the speed of dynamic contact of a vacuum circuit breaker
a differential moving magnet type magnetoelectric speed sensor is designed. Through the transformation of electromagnetic induction law formula and finite element analysis of the permanent magnet magnetic field
the structure of the speed sensor is obtained.Through the analysis of the sensor output-input characteristics
the connection method of coil is determined. By analyzing the sensor’s magnetic field distribution
a magnetic flux algorithm and the solution are given. And the performance of the magnetoelectric speed sensor is also analyzed. Simulation analysis is carried out via commercial software on the magnetoelectric speed sensor
and the results show that the structure and performance of the magnetoelectric speed sensor are satisfactory.
