摘要： Provided is an apparatus, such as an arc mitigating device, which can include a first plasma generation device and a second plasma generation device. The second plasma generation device can include a pair of opposing and spaced apart electrodes and a low voltage, high current energy source connected therebetween. A conduit can be configured to direct plasma between the first and second plasma generation devices, such that the second plasma generation device receives plasma generated by the first plasma generation. The plasma from the first plasma generation device can act to reduce the impedance of an area between the pair of opposing electrodes sufficiently to allow an arc to be established therebetween due to the low voltage, high current energy source.

摘要： Provided is an apparatus, such as an arc mitigating device, that includes an annular body that defines a lumen and a longitudinal axis, the annular body having a body length along the longitudinal axis. An electrode can be disposed coaxially within the lumen. The electrode may extend into the body by an electrode length that is at least about 50% of the body length, and may have diameter less than or equal to about 50% of an inner diameter of the annular body. An ablative material portion can be disposed between the annular body and the electrode. The annular body and the electrode may be configured such that when an arc exists between the annular body and the electrode, the ablative material portion undergoes ablation and thereby generates a plasma.

摘要： A plasma gun with two gap electrodes on opposite ends of a chamber of ablative material such as an ablative polymer. The gun ejects an ablative plasma at supersonic speed. A divergent nozzle spreads the plasma jet to fill a gap between electrodes of a main arc device, such as an arc crowbar or a high voltage power switch. The plasma triggers the main arc device by lowering the impedance of the main arc gap via the ablative plasma to provide a conductive path between the main electrodes. This provides faster triggering and requires less trigger energy than previous arc triggers. It also provides a more conductive initial main arc than previously possible. The initial properties of the main arc are controllable by the plasma properties, which are in turn controllable by design parameters of the ablative plasma gun.
