A functional approach to the analysis of technological processes of using thermal radiation in the process of repairing insulation of electric locomotive equipment

Abstract

Abstract The article provides an analysis of the interaction of the system “Emitter – Environment – Material” in the drying and hardening of the insulation of electrical equipment of electric locomotives, taking into account the intended purpose of the process. The structural-logical diagram of technological processes of using thermal radiation during repair of insulation materials of windings of power equipment of electric locomotives is presented. This structural and logical diagram indicates the need for an individual approach to the analysis of the system elements’ interaction in the process of using heat radiation for the polymerization of impregnating materials for hardening. It is necessary to comply with the parameters of the maximum permissible temperature and heating rate not only for isolation of this class of heat resistance but also for an impregnating material, depending on which losses in the medium depend. A simplified approach to the analysis of the interaction process of the “System” elements in the mathematical model is proposed. The basis of this model is the relationship between the dose of irradiation of polymer insulation with thermal radiation and the expected results on the characteristics and properties of electrical insulating materials.
