The invention relates to a 10 kV switch cabinet comprising a cabinet body and a cabinet door. The cabinet body is equipped with a live code chip of which the QR code content can be modified. The cabinet body is equipped with a scanner for scanning the live code chip. The scanner is connected with a display and a control power supply. The scanner scans the live code chip to acquire the word and image prompts of the switch cabinet, and displays a source of danger through the display. The cabinet door is arranged on the cabinet body through an electronic lock. The control power supply is electrically connected with the electronic lock. The advantages are as follows: through the live code chip, the information needed for ensuring the safety of the switch cabinet in different states can be stored, maintainers only need to scan the live code chip through the scanner to acquire the word and image prompts of the switch cabinet, maintainers can read the information of the switch cabinet before maintenance, the safety during maintenance is improved, and personal casualty is avoided; and through the display, the source of danger in the switch cabinet can be visually displayed to maintainers so maintainers can make a comprehensive analysis.
