Study on Relationships between High-Frequency High-Voltage Pulse Breakdown Voltage of Air-Gaps and Pulse Delay Time

In the paper, power frequency and high-frequency high-voltage pulse breakdown voltage of air-gaps were measured by circuits of spark gap switches respectively, and then output waveforms were obtained by sampling circuits, finally a large number of data in experiments were recorded and were drawn into curves. It can be seen from curves: firstly, relationships between pulse breakdown voltage of air-gaps and pulse delay time or between pulse breakdown voltage of air-gaps and pulse coefficient are discussed when electrodes and distances between electrodes are different, secondly, relationships between pulse breakdown voltage and air-gap distances are analyzed under 100kHz pulse voltage when electrodes are spherical electrodes.
