Switch cabinet sensor voltage visualization intelligent device and method

The invention provides a switch cabinet sensor voltage visualization intelligent device and method. The device comprises an insulating shell, a voltage display, a live-line alarm lamp and a voltage measuring probe. A power supply module, and a voltage measurement module, an A/D conversion module, a data conversion module and a digital display module which are connected in sequence are arranged in the insulating shell; the power supply module supplies power to the voltage measurement module, the digital display module, the A/D conversion module and the data conversion module. According to the invention, the internal voltage of the electrified display is detected, and then the voltage data is displayed on the display screen, so that the detection is flexible, and the inspection efficiency is high. The insulating shell is connected with the measuring probe to achieve insulation between a human body and voltage, the safe working environment of detection personnel is further guaranteed, the electric shock risk is
