Title: Motion characteristics of long ac arcs in atmospheric air

Abstract

Experiments on the motion of long alternating current arcs in atmospheric air show that the anode and cathode arc roots have different motion characteristics because of different formation mechanisms. During a half cycle of the arc current, the anode arc root moves towards the direction of magnetic force and occasionally has a jumping motion, while the cathode arc root moves sufficiently slow to consider it stationary and hardly has any jump. The arc column has a complex shape and moves under the drive of the magnetic force and is also quickened by the lower arc root.

  • A theoretical model for the unit cross section of a 1-atm unbounded arc was used to investigate arc behavior. The electrical source was taken as a dc voltage and resistance in series. Because the simulated arc is not radially bounded, the arc V-I characteristic is found to be time varying and dependent on the source values. The results of exercising the model also show that the central temperature of the arc is maintained in the neighborhood of 70,000 K and that changes in the source values can only raise this temperature for times on the order of 100 ..mu..s, approximatelymore » the time for diffusion of a temperature perturbation from the core of the arc to its periphery. The growth of the arc into ambient air is governed by the diffusivity of the ambient air, and is considerably slower.« less
  • In room-temperature atmospheric air, the large-scale diffuse plasmas can be generated via high-voltage nanosecond pulses with short rise-time and wire electrodes. Diffuse discharge with the wire electrode length up to 110.0 cm and the discharge spacing of several centimeters has been investigated in this paper. Electrical characteristics of diffuse discharge have been analyzed by their optical photographs and measuring of the voltage and current waveforms. Experimental results show the electrode spacing, and the length of wire electrodes can influence the intensity and mode transition of diffuse discharge. The characteristic of current waveforms is that there are several current oscillation peaks atmore » the time of applied pulsed voltage peak, and at the tail of applied pulse, the conduction current component will compensate the displacement one so that the measured current is unidirectional in diffuse discharge mode. The transition from diffuse discharge to arc discharge is always with the increasing of conduction current density. As for nanosecond pulses with long tail, the long wire electrodes are help for generating non-equilibrium diffuse plasmas.« less
  • The role of electrode surface and, especially, the effect of work function of a composite electrode surface in the transition process from micro-arcs to big-arcs under atmospheric pressure plasma conditions have been analyzed using an arcspot model. It is seen that the transition from microarcs to big-arcs occurs at relatively high work function values. An increase in the work function of a composite electrode surface results in arcs which carry higher currents, and have higher arcspot temperatures. The critical arc current for the transition to this high-current big-arc mode is found to depend both on the electrode work function andmore » on the electrode temperature. The model can also be used to predict the arc-spot temperature for any given arc temperature value.« less
