Study on Microcosmic Mechanism of Scattering Cross Section of Environmentally Friendly Mixed Gas Insulating Medium
In order to promote the development of a new type of environmentally friendly insulating gas for the insulating medium of power equipment,this paper adopts the microscopic calculation method of quan-tum mechanics,takes the collision scattering cross section of electron/gas molecules as the calculation target,and adopts the close coupling approximation method to calculate the 00-00 elastic collision and 00-02 of the He-H2 mixed gas multi-particle system when the relative collision energy E=0.2 eV.00-04 Differential re-flection cross section of inelastic(rotational excitation)excitation collision,further analyze the impact of rela-tive impact energy value on elastic and inelastic collision calculation results,summarize the variation law of differential scattering cross section of the collision system,and provide theoretical basis and guidance for ex-ploring the mechanism of insulation characteristics of mixed gas.The results show that the 00-00 elastic col-lision differential cross section of He-H2 mainly occurs in the small Angle part,the scattering of 00-02 in-elastic collision mainly occurs in the large Angle part,and the 00-04 transition can be realized,but the in-elastic collision differential cross section is very small,and the 00-06 excitation of He-H2 collision is impos-sible to be realized.
