摘要

数值模拟被广泛应用于高压气爆断路器灭弧装置中电弧与气流之间能量交换的研究。在大电流阶段,影响能量交换的主要因素是辐射。用于描述辐射传热的数值模型包括一个吸收系数,它取决于许多参数。主要参数是气体的温度和压力以及等离子体柱的半径。本文研究了主要灭弧介质:干燥空气(N2)、SF6、CO2,温度为300 ~ 30 000 K,压力为1 ~ 30 atm,等离子体柱半径为1 ~ 40 mm。

The Absorption Coefficient in Various Gases in the Range of Temperatures of 300–30 000 K and Pressures of 1–30 Atm

Numerical simulation is widely used in the study of energy exchange between the arc and the gas flow in arc-quenching devices of HV gas-blast circuit breakers. In the high-current phase, the main factor that influences energy exchange is radiation. Numerical models used to describe radiative heat transfer include an absorption coefficient, which depends on many parameters. The main parameters are the temperature and pressure of the gas and the radius of the plasma column. In this paper, the absorption coefficient for the main arc-extinguishing media was investigated: dry air (N2), SF6, CO2 in the temperature range of 300—30 000 K and pressures of 1–30 atm with plasma column radii in the range of 1–40 mm.
