Abstract

The article is devoted to continue presenting the results of experimental studies on the identifi-cation of rational modes of IR energy supply in encapsulation technology insulation windings of electric machines (EM) of traction rolling stock (TPS). In this paper, published the results of com-paring the effectiveness of the use of various oscillatory modes of infrared (IR) energy supply in the process of winding insulation encapsulation the frontal parts armature winding of the traction mo-tor type NB-514B electric locomotives series "Ermak" on the process plant at their depot and fac-tory repair. In studies to identify rational oscillating modes IR energy supply option duty cycle remained unchanged for the existing design of the generator of heat radiation technological installation, and changed only option cyclical, characterized by changing the speed of rotation of the armature trac-tion motor on the plant corresponding to 5, 25 and 50 Hz when the drive installation works from the frequency converter. The process of encapsulation was carried out first only short-wavelength radiation generated incoherent halogen emitters, then only at medium-wavelength radiation generated pulse ceramic radiators, and finally - with alternating heating medium short- and medium-wavelength radiation, i.e. with these two types of emitters in the spectral-oscillating mode IR energy, on which is currently obtained patent for the invention. For comparability of experimental studies same dose irradiation of segments frontal part of the armature windings of the traction motor type NB-514B electric lo-comotives «Ermak». Objective factors when comparing encapsulation modes to identify the most efficient are pa-rameters such as dielectric strength (the value of the breakdown voltage insulating tape) and ce-menting capacity.
