The power supply system at the construction site shall strictly implement the TN-S system (see the attached figure: Site Temporary Power Layout Plan for details). The power supply line adopts five core cable, and the power supply system at the construction site is "three-level power distribution" and "two-level protection". The motors at the construction site shall strictly comply with the standard requirements of "one machine, one switch" and "one leakage and one box": main power supply → primary distribution cabinet → secondary distribution box → tertiary switch box → electrical equipment. 1. The design site of lightning protection and grounding shall be equipped with two sets of grounding electrodes for each tower crane. The 50X5 hot galvanized flat iron shall be reliably welded with the tower crane foundation bottom plate reinforcement and led to the tower crane ladder to prevent lightning strikes. The grounding resistance shall not be greater than 4 Ω. According to the mechanical power used on the construction site and the power consumption of other electrical equipment and lighting, according to the construction schedule, the maximum number of mechanical equipment that simultaneously use electricity during the peak construction period. The power consumption of the construction elevator is separated from that of the tower crane, so the power consumption of the external elevator during the construction is not considered. The tower crane can be gradually removed in the secondary decoration stage to meet the power consumption of the external elevator. For the main structure, the power load of steel and wood processing plants can be transferred to the secondary decoration stage. The demand of various mechanical equipment in construction shall be calculated by coefficient.
