Non-firefighting cutoffs are different with regard to their cutoff mode, time, and cutting points. Based on an analysis of the types and characteristics of non-fire loads, the influence of the power cut, fire location, operation and management requirements, and other aspects, the corresponding cutoff mode, time, and cutoff points are given for different cutoff objects. An optimized non-firefighting power cutoff scheme is examined. For a three-stage load, the power outage will not affect the operation or rescue and can be automatically and immediately cut off. Loads with a fixed control process can be cut off automatically. Loads without a fixed control process can be cut off manually. The elevator, platform door, AFC gate, and entrance guard can be cut off after execution of the control logic command. It is safer to perform a cutoff in the low-voltage distribution cabinet of the substation. The authors suggest that normal lighting and a small power box can be cut off in different areas of the distribution box.
