Еffect of climatic factors on service life of insulating materials of traction electric machines

Abstract

The aspects of operation of electrical equipment under the influence of limit values of a number of climatic parameters, as well as the performance of equipment with a change in altitude, are considered. The results of experimental comparative studies of the electrical insulation resistance of TEM samples based on the insulation temperature resistance class of 220 with serial samples based on class F or H are presented. Based on the results of comparative tests confirmed the expediency and prospects of application of insulation class 220. The analysis of the results of the impact of climatic factors on the physical and mechanical properties and service life of insulation materials, as well as the safety and quality of electrical equipment.
