| 主权项 | 1. A pre-cover-opening power-off method, comprising the steps of: (a) fixing a bolt casing provided with a motion sensor to a bolt which has been screwed into an electrical equipment cover plate; (b) connecting the motion sensor to a safety protecting and monitoring unit in a wired or wireless manner; and (c) when the bolt casing is fixed to the bolt, the motion sensor is activated so that the motion sensor sends out a signal, and the safety protecting and monitoring unit, upon receiving the signal, sends out a command to permit power delivery for the electrical equipment to operate; and when the bolt casing is taken off, the motion sensor is activated so that motion sensor sends out another signal, and the safety protecting and monitoring unit, upon receiving the other signal, sends out a command to cut off a power supply for the electrical equipment or give out an alarm. | ||
