Description

Technical Field

[0001] The invention relates to the technical field of steel production, and in particular to a system and method for comprehensive protection of high-speed wire finishing rolling excitation inlet. Background Art

[0002] The excitation incoming line system of high-speed wire finishing rolling is transformed from three-phase AC 380V to three-phase AC 170V through a transformer, and then rectified by a rectifier trigger. The rectified two-phase DC 75V supplies power to the excitation winding of the finishing motor. The current load of the entire excitation system is very large, reaching 406A on the DC side. Therefore, when a fault occurs, it will be reflected in the temperature of the transformer winding dedicated to the excitation system. However, since the inspection cycle is 2 hours, uninterrupted real-time protection cannot be achieved. If the temperature degradation trend can be discovered in advance, the excitation transformer, rectifier trigger, excitation coil, excitation collector ring, etc. of the entire excitation system can be prevented from further damage;

[0003] The actual situation of the prior art is that the excitation transformer only has temperature display, but no related protection technology, which brings great hidden dangers and uncertainties to the safety and stability of the entire high-speed wire finishing rolling excitation incoming line system. Furthermore, the prior art of the motor winding incoming line connection of the excitation incoming line is a soft connection. Since the load reaches 406A, the connection is often burned. Due to the small space and long processing time, each occurrence of the above problem will cause the finishing rolling to trip and pile up steel, which will lead to production interruption and equipment accidents. Therefore, the present invention proposes a system and method for comprehensive protection of high-speed wire finishing rolling excitation incoming lines to solve the problems existing in the prior art.
