The reliable storage of spring potential energy is a prerequisite for ensuring the correct closing and opening operations of a circuit breaker. A fault identification method for circuit breaker energy storage mechanism, combined with the current-vibration signal entropy weight characteristic and grey wolf optimization-support
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
Abstract: In recent years high-speed electromagnetic repulsion mechanism (ERM), which is produced based on the eddy-current effect, has been widely applied to vacuum circuit breakers. One of the challenges for the design of ERM is to improve the speed of ERM by optimization design.
All operating mechanism functions are integrated in the magnetic actuator of the AMVAC circuit breaker. The actuator is a bi-stable magnet system, in which armature change-of-state is accomplished by the magnetic field of two electrically excited coils. The armature is held magnetically in the limit positions by the fields of two rare-earth

The VM1 vacuum circuit-breaker finds its universal range of applications throughout the chain from power generation in power stations through controlled distribution in transformer substations to the final consumer, such as the chemicals industry, steel industry, automobile industry, airport and building power supply.
All operating mechanism functions are integrated in the magnetic actuator of the AMVAC circuit breaker. The actuator is a bi-stable magnet system, in which armature change-of-state is accomplished by the magnetic field of two electrically excited coils. The armature is held magnetically in the limit positions by the fields of two rare-earth
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry ( overcurrent ). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which operates once and then must be replaced, a
The objective of this paper is to develop an electromagnetic repulsion mechanism for a 40.5 kV vacuum circuit breaker and then to make an optimization. Design of experiments (DOE) method are used to screen the prominent factors.
