$SF_6-N_2$ 혼합기체의 절연특성에 관한 연구
A study of the Insulation Characteristic in $SF_6-N_2$ Mixture Gases
초록
This SF6 gas is widely used in industrial of insulation field. In this paper, N2 is mixed to improve pure SF6 gas characteristics. Electron transport coefficients in SF6-N2 mixture gases are simulated in range of E/N values from 70 to 400 [Td] at 300K and 1 Torr by using Boltzmann equation method. The results of this method, which are like electron drift velocity, ionization coefficient, attachment coefficient, effective ionization coefficient, and critical EIN, can be important data to present characteristic of gas for insulation. Specially critical E/N is a data to evaluate insulation strength of a gas and is presented in this paper for various mixture ratios of SF6-N2 mixture gases. ?⨀ ␍? ܀㘱〮㜳㬓M敤楣楮攠慮搠桥污瑨
