Research on Composite Magnetic Field Contact of DC Vacuum Circuit Breaker and Its Arc Behavior
A composite magnetic field contact dedicated to DC vacuum circuit breaker is designed. Magnetic field simulation and DC breaking experiments were completed for this type of contact. The breaking current amplitude is 5 1kA, the commutation frequency is 3000 Hz, and the arc image is taken by high speed photography. The simulation analyzes Magnetic field distribution of composite magnetic field contacts and the Lorentz force of the arc on the contact surface. The trend of the arc is predicted. Experimental results show, under the condition of DC low current medium frequency breaking, the AMF-TMF contact can effectively drive the arc rotation. However, the rotation effect is not obvious. And the arc can move to the Axial Magnetic Field contact under the influence of the magnetic blowing force. The arc maintains the diffusion state after the contact reaches a certain opening distance, then it is extinguished when the current crosses zero. This kind of contact meets the demand of DC low current breaking.
