The Study Of Electric Locomotive Main Transformer Technology State Detection And Evaluation Method

Electric locomotive main transformer at the core of electric locomotive parts, bear an important responsibility of guarantee locomotive normal continuous operation, electric locomotive main transformer fault or not is key to smooth efficient locomotive transport passengers and goods one of the important factors.This topic describes the electric locomotive main transformer test type, the method and principle, studied the transformer insulating oil assay and the relationship between the fault, electric locomotive main transformer are analyzed for the purpose of the second annual inspection and its test method and maintenance technology, combining with an instance of repair electric locomotive main transformer faults are studied to predict and analyse the situation and its application of design process improvement.Accounts in electric locomotive main transformer and the types, principles and methods of the experiment when electric locomotive main transformer is described in detail and the difference between the traditional power transformer, from the principle and main technical parameters, main wiring design, arrangement of external structure, size and shape terminal layout, the main transformer circulating cooling principle and protection function illustrates several aspects, such as the basic structure and principle of electric locomotive main transformer will be14, including type test and routine test project, the test article reveals the main transformer test purpose, method and evaluation indicators, through to the electric locomotive repair technology and its second annual inspection purpose, transformer test, the relationship between transformer oil test and fault detection of research and anticipation of transformer faults such as data collection for the analysis of electric locomotive transformer maintenance and fault forecasting process and method, it is concluded that electric locomotive main transformer oil gas content, with three maintenance examples illustrate electric locomotive two yearly check transformer troubleshooting analysis and processing, electric locomotive main transformer fault forecasting and design improvement.This subject aims to combine the key maintenance case study through a variety of test especially that the index of electric locomotive main transformer insulation oil fault state judgment and transformer maintenance and repair of meaning, and to achieve continuous improvement in transformer design and process, improve the level of maintenance, according to the realization of the fault forecasting efficiency highest accurate positioning fault fast and efficient maintenance of transformer. and hope this topic research summarized a set of suitable for electric locomotive overhaul transformer has the guiding significance of the article.to fill the domestic lack of electric locomotive overhaul transformer guidance paper blank.
