Abstract
In the article it is shown that the optimal frequency of maintenance of systems of electric traction is determined by its reliability, as well as the average time spent on the performance of one maintenance (M). More reliable equipment should be serviced less frequently. In addition, the more time is spent on one service, one can deeply control the equipment and prevent more failures, and hence the maintenance period increases. Determination of the frequency of maintenance on the basis of the results of periodic control of the parameters of equipment and its elements allows you to determine the most expedient term of maintenance, as well as the elements used. A feature of standard methods for determining the frequency of maintenance is that they require the availability of certain statistical data on the operation of elements of equipment or equipment in general. This circumstance greatly complicates and increases the error of calculations, which is not unimportant factor in determining the methods of periodicity of maintenance. They also do not allow to judge the feasibility of carrying out maintenance on this particular equipment of electric traction systems. Unlike these methods, determining the frequency of maintenance based on the results of periodic monitoring of equipment parameters and its elements allows you to determine the most appropriate period of maintenance, as well as elements whose preventive replacement is most appropriate. Mathematical relations are obtained for the choice of periodicity of maintenance from the condition of maximum probability of detection of a malfunction. The algorithm of the sequence of the calculation of the optimal terms of the maintenance is developed. The mathematical description of the optimal value of the period between maintenance with the condition of the minimum value of the non-working condition factor is obtained. The method of the choice of periodicity of technical maintenance is offered from the condition of the minimum factor of the non-operating condition of the equipment.
