Beijing - A hotel decoration electrical completion drawing
1、 Design overview: This project is the interior decoration design project of Yanqing Jingliang Maisui Express Hotel. 2、 Design content: 1. This design includes the power distribution and emergency lighting system of lighting, socket and air conditioning system in the decoration area. 2. Power distribution trunk system, power system, lightning protection and grounding system 3、 Power supply and distribution system: 1. This design is a decoration design project, and the load levels of various equipment are subject to the original civil electrical design. 2. The power supply voltage of the project is 380/220V, and the power is introduced from outdoor box type transformer. 3. In this project, a power distribution room is set on the first floor, and the power, lighting, etc. from the power distribution room are laid through steel pipes or cable trays. 4. The general lighting in the guest room is led out from the distribution box in each guest room, and the non emergency lighting in general places is led out from the general lighting box. 4、 Lighting system: 1. Refer to the decoration drawings for the positioning dimensions of all lighting fixtures and electrical equipment. High luminous efficiency energy-saving lamps are used as fluorescent light sources, and the power factor of energy-saving electronic ballasts is not less than 0.9. Damp proof enclosed special lamps shall be used in wet places such as shower rooms. The electrical connections of various lighting lamps and the direct contact with the ceiling shall be properly sealed. All lighting circuits shall be equipped with a special PE for connecting lamps (such as Class I lamps) with installation height less than 2.4m and grounding requirements and relevant equipment. Pay attention to wiring as required. 2. Evacuation lighting and emergency evacuation indicator light, with battery, emergency lighting time ≥ 30 minutes. 3. The enclosure glass of emergency evacuation indicating lighting must be made of non combustible materials. 4. Lighting and socket are powered by different branches; All sockets are equipped with leakage circuit breaker protection. 5. The lighting lamps in the elevator shaft shall be of installation type. The upper end of the elevator shaft is 0.5m from the top and the lower end is 0.5m from the bottom of the shaft. A 13W waterproof energy-saving lamp is installed 5-7m from the top of the shaft, and 36 generator low-voltage power supply is used. Control switches are set in the machine room and the pit. The elevator shaft maintenance socket is installed 0.5m from the top of the shaft, 0.5m from the bottom of the shaft and every two floors. 16A waterproof socket is used. 6. See the decoration professional drawings for the positioning dimensions of all lighting fixtures and electrical equipment. 5、 Equipment installation: 1. The distribution box of each floor and guest room is embedded in the wall. The distribution box in the distribution room is mounted on the wall in an exposed manner. 2. Evacuation instructions not installed on the wall in the drawing are hoisting at 2.0m from the lower opening to the ground.
