Abstract

Maintenance technology is an algorithm for assigning measures to maintain the specified technical condition of TP and CM equipment during their operation. The operable state of TP and CM is achieved by performing tasks: predicting changes in parameters and strength; designation of parameter tolerance limits; determination of parameters and patterns of load changes; development of device failure models; collecting information about the current state of devices and analyzing the causes of failures; development of diagnostic tools and methods; selection and calculation of maintenance technology parameters; organization of maintenance and repair system works.

The process of technical maintenance and the time of KD can be optimized. Optimization criteria can be indicators of device readiness or minimization of time and material costs for TP and KM maintenance. The following indicators of the maintenance and repair system have been approved: average and specific duration, labor intensity, cost, availability and technical use coefficients.

Given the complex operating conditions of the CM and the fact that it actually has no redundancy, it is necessary to continuously monitor the reliability indicators of the system as a whole and its elements in particular. With the help of these indicators, it is possible to determine the most appropriate technologies, organization, periodicity and volume of preventive and repair work for the maintenance of KM and optimization of these works under the condition of economy.

New technologies for the operation of contact networks and the implementation of reliable and economical current removal on urban electric transport are proposed. Considered theoretical and practical issues of maintenance and repair technologies of the contact network by condition. The fundamental criteria of the state of the contact network and the quality of current collection are generalized. Experimental studies of the contact network were carried out and a method of assessing the quality of current removal and the condition of contact suspensions based on the dependence of contact pressure was proposed.
