The invention provides a printed board and a printed board protection method. The printed board comprises a substrate, a partition plate vertically arranged on the substrate, a detection module, an arc extinguishing module and a control module. The arc extinguishing module is arranged in the central area of the partition plate and stores arc extinguishing substances; the detection module is arranged in the edge area of the partition plate and connected with the arc extinguishing module and the control module. The control module is used for transmitting the environment detection data acquired by the detection module to the control module of the electrical equipment to which the printed board belongs, and sending a protection instruction to the control module of the electrical equipment to which the printed board belongs when a first arc safety protection condition is met; and the arc extinguishing module is used for releasing an arc extinguishing substance when the environment detection data acquired by the de
