However, due to the complexity of the construction environment and the diversity of electrical equipment, the risk of electrical accidents also increases. By setting up an electricity safety warning system, it is convenient to monitor the power operation status in subway construction in real time, timely discover and warn potential electrical faults, and effectively prevent the occurrence of electrical accidents.

[0003] The power system usually includes a distribution room and connecting lines. The distribution room is connected to the construction tunnel and is equipped with distribution equipment. The connecting lines are used to connect with other power equipment. During the construction process, some connecting lines are set close to the inner wall of the subway. The safety warning system for the power system usually includes a flame sensor and an audible and visual alarm. When the flame sensor senses a fire, the audible and visual alarm is sounded by the audible and visual alarm, and then the relevant staff uses a fire extinguisher to extinguish the fire at the fire site.
