摘要
FIELD: electric railway transport. SUBSTANCE: facility of power supply and adjustment of auxiliary machines of A C electric locomotives has asynchronous squirrel-cage motors fed from winding of auxiliaries of power transformer through phase splitter. Proposed facility provides for possibility of switching of machines to reduced speed with their power supply through additional direct frequency converter built on thyristors. This frequency converter can be connected with its output to input of rotating phase splitter feeding supply voltage to electric motors of drives of auxiliary machines. EFFECT: simplified design and provision for reduced productivity of mentioned- above auxiliary machines. 3 dwg
