Abstract
EN: Abstract. The review of methods of post-repair tests of traction asynchronous motors under conditions
of locomotive depot is carried out.The necessity of introducing special stands for post-repair tests is
shown in order to improve their quality, reduce the number of failures of service equipment, improve
safety of the railway transport. Let's consider a question of power supply of the research asynchronous
engine in wide frequency range and also a possibility of creation of the universal stand for testing
important asynchronous engines of the electrorolling stock. Survey of possible versions of the scheme
mutual loadings of asynchronous electrical machines which can be used for testing traction asynchronous
engines of the rolling stock is executed. Such systems can be constructed both with use of the static
converter of frequency, and without it. The given short characteristic of each alternative, certain
advantages and shortcomings of each of system options. It is shown that systems with use of static
converters of frequency differ in high power efficiency, allow to carry out tests in the wide frequency
range of power supply, however have higher prime cost. Schemes without converters of frequency differ
in smaller power efficiency, impossibility to carry out tests in the wide range of frequency of power
supply, high level of consumption of reactive power . The results of the carried-out analysis can be used
when choosing rational option of a system mutual loadings of asynchronous electric motors which will
differ in higher functionality and power efficiency. Use of such systems will allow to lower capital
expenditure for creation new and modernization of traction electrical machines that exist at the station for
test.
