Abstract
This application discloses a hydrogen production rectification control system based on the Siemens 6RA80, relating to the technical field of hydrogen production rectification control devices. By electrically connecting the 6RA80 controller to the rectifier cabinet in the hydrogen production unit, the original analog circuit adjustment board and phase shifter board are replaced. The 6RA80 controller integrates thyristor triggering and voltage / current stabilization functions. Through electrical connection with the rectifier cabinet, it achieves precise control of the rectifier cabinet's output current / voltage, ensuring that the current and voltage of the electrolyzer remain stable within the set range. The 6RA80 controller replaces all parameters such as voltage limiting, current limiting, overcurrent, voltage feedback strength, and current feedback strength, which are traditionally set by potentiometers, with fully digital settings within the controller itself, achieving transparency, standardization, and precision in parameter settings. This solves the technical problems of large current fluctuations, low adjustment accuracy, inconvenient parameter settings, and weak anti-interference capabilities in traditional hydrogen production rectification control systems.
