METHOD AND APPARATUS FOR CALCULATING ELECTRIC ARC RADIATION ENERGY OF ELECTRIC POWER SWITCH DEVICE, AND DEVICE

A method and apparatus for calculating the electric arc radiation energy of an electric power switch device, and a device. The method comprises: constructing a two-dimensional electric arc simulation model for an electric power switch device according to a fundamental equation of two-dimensional magnetohydrodynamics; performing iterative calculation in the two-dimensional electric arc simulation model according to the initial temperature and initial pressure of the electric power switch device, so as to obtain temperature data that meets iterative constraint conditions; and according to the temperature data and the electric arc radius of the electric power switch device, calculating the electric arc radiation energy of the electric power switch device. Radiation calculations of different regions of an electric arc are taken into consideration, such that a calculated radiation energy result has a high accuracy and a rational physical mechanism, the existing need to solve a radiation transport equation is avoid
