title = "Experimental study on DC inductive arcs driven by magnetic fields",
abstract = "Electrical arc within a pair of AgSnO2 contacts was investigated when a DC inductive circuit was opened at different velocities. The arc was driven by axial and transverse magnetic fields. A 28V/5A inductive circuit was adopted as the experiment circuit, of which the time constant was 2 ms. Density of both the axial and the transverse magnetic fields varied from 0 mT to 200 mT. The opening velocity varied from 10 mm/s to 50 mm/s. A high speed camera and an oscilloscope were used to record time variations of arc images and arc voltages, simultaneously. Relationships between flux density and arc parameters, such as arc durations, arc stagnation time, distribution of arc positions and arc root velocities, were obtained at those opening velocities. Material transfer mass was measured at every 5000 breaking operations. Influences of the magnetic fields on the transfer mass were obtained under two types of the magnetic fields at those velocities. The results can be used to design magnetic blow contacts in switches.",
