| Abstract: | The principle of a new kind of gas-gap switch is presented in this paper.A detailed theoretical analysis taking into account the gas conduction in continuum or rarefied state and the axial conduction in the fins is presented.A theoretical heat transfer model is built for this kind of switch.The relationships between thickness of the fin,length of the fin,gap clearance between fins and on-inductance are given.The off-inductances as functions of gas pressure,thickness of exterior wall are also shown. |
