Abstract
An intelligent digital controller for a mine rectifier cubicle belongs to a rectifier cubicle controller and mainly solves the technical problems of the existing controller that the digital display is not accurate, the current control precision is not enough, and the structure is complex and inconvenient to repair. A single-chip microcomputer is used as a digital control core, and a digital circuit is simple with strong anti-interference ability. The collected voltage, current analog amounts are converted into digital switch amounts by the single-chip microcomputer, the current and the voltage are displayed by a common anode digital tube and compared with the voltage and the current which have been preset in programs; if the output voltage exceeds the preset voltage, the single-chip microcomputer outputs an over-voltage alarm signal to prompt staff to pay attention to the output voltage of a rectifier. If the output current exceeds the preset voltage, the single-chip microcomputer outputs an over-current alarm signal and a power supply of the rectifier is cut off, so as to protect electrical equipment. The controller is mainly used for the mine rectifier cubicle.
