Development of Mine-used Feedback Type Frequency Converter with Flameproof and Intrinsic Safety
摘要
Abstract
In view of problems that two-quadrant frequency converter can not feedback energy and design selection of braking resistant in two-quadrant frequency converter + resistant braking unit may not match with field conditions, a mine-used feedback type frequency converter with flameproof and intrinsic safety was designed. Design of main circuit and application effect of the feedback type frequency converter were introduced in details. The actual application shows that the frequency converter can feedback energy to power grid through rectify unit in range of rated power and meet with requirement of electric power and feedback power are less than 160 kW.关键词
