Latest Patents
One of his latest patents is an electromechanical circuit breaker and method of breaking the current in said electromechanical circuit breaker. This innovative device is designed to establish and break the current in a main circuit. It comprises a fixed contact element and a moving contact element that are in electrical contact for carrying the current. The moving contact element can be displaced to a second position, separating it from the fixed contact element to cut off the current. The circuit breaker features a blow-out device with a magnetising coil that generates a magnetic field to drive an arc generated by the separation of the contact elements into an arc extinction means. This design allows for high breaking efficiency, even when dealing with smaller currents.
Another significant patent is a switch that incorporates a vacuum interrupter. This switch features a vacuum interrupter housed between two supply terminals. The vacuum interrupter consists of a tubularly constructed, evacuated housing with both fixed and movable contact members. The design ensures that the vacuum-tightness of the vacuum interrupter is maintained during manufacturing assembly and operation, preventing any undesired forces from damaging the bellows.
