【正文】 od is applied to implement illumination calculation, and the needed coefficient method is applied to implement the load calculation, and the cross sections of the circuits are selected according to longterm allowable temperature rise and voltage loss, and the lowvoltage breakers are selected according to the maximum working current and line protection conditions. Socket and lighting circuits are arranged in different supply loop, and leakage protection breaker is applied in socket loop. Lighting protection with the 3rd level is designed in accordance with specifications, and grounding system adopts TNS system, and general equipotential connection, togenther local equipotential connection is designed. The overall design accords with the relevant technical regulation requirements. Equipments selection is reasonable so as to better meet the applicable functions, and be able to better guide the construction.
