1. Strong electricity project. Water supply and drainage works. High-voltage transformer and distribution system, low-voltage transformer and distribution system, lighting system, accidental lighting system, automatic fire alarm system, water supply and drainage system. 2.Weak power engineering. Telephone. Closed circuit. Comprehensive wiring system. Automated office system. Strong electricity part. The strong electricity part of this project includes high voltage distribution system. Low-voltage distribution system. Power system. Lighting system. Accident system. Lightning protection and grounding system. Set up substation in the basement, so that the high-voltage power supply from the municipal power grid led to two 10KV power cable buried directly into. Also set up another diesel generator set for power outages. The project grade is divided into three levels, including emergency department, operating department, central monitoring, maternity ward, baby room, blood dialysis center, medical imaging center, accident emergency lighting, evacuation instructions and safety exit lights, fire electrical equipment, fire control room, elevator power, information centers, life pumps and sewage pumps, etc. for the first level, the electronic microscope, advanced wards, etc. for the second level, and other electrical loads for the third level. One or two loads are powered by dual power cables, which are automatically switched in the end distribution box. Fire control room information center. Operating room, calculator room, X-ray room, etc. X-ray room, etc. to install UPS power supply cabinet to ensure the reliability of power supply; accident emergency lighting both as usual lighting, when a fire occurs by the control room to control its forced lighting, become an accident lighting. The grounding system of this project is TN-C-S type, and the grounding resistance is not more than 1 ohm. High voltage distribution system. Inpatient building basement substation, its high-voltage power supply from the municipal power grid to introduce two 10KV power cable buried directly into the high-voltage inlet cabinet, inlet cabinet and calculation cabinet, inlet isolation cabinet, contact cabinet and contact isolation cabinet plus electrical and mechanical interlocks. High-voltage circuit breakers using vacuum circuit breakers, direct system operating system. Low-voltage power distribution system. Low-voltage distribution system grounding adopts TN-C-S system. The working zero line and grounding protection line are separated from the low voltage switchgear of the transformer and distribution center and are not connected. The distribution voltage is 220/380V, and the distribution method adopts the combination of radial type and trunk type, and radial type power supply is adopted for the loads with large single capacity or main loads.3. Power system. Refrigeration unit. Fire-fighting water pump. Living water pump. Elevator, etc. Radial power supply. Fan. Fire shutter. Air conditioning and other trunk-type power supply, in order to ensure the power supply of important loads, important equipment such as the emergency department. Surgical Department. Infant department. Blood Stealing Center. Fire control room. Elevator power. Domestic water pumps etc. are primary power supply, electron microscope, advanced wards are bipolar power supply and others are tertiary. One. Secondary loads even with double power cable power supply, in the end of the distribution box is automatically set to change the fire control room information center. Operating room. Calculation room. X-ray room and other installation of USP power box cabinet to ensure the reliability of power supply; accident emergency lighting both as usual lighting, when a fire occurs by the control room to control its forced lighting, become an accident lighting. The main power distribution trunk line is led from the substation along the cable bridge (trunking) to each electrical shaft and then to the sub-distribution box. The main power distribution line adopts closed wire mother. Highly flame retardant copper core cable or wire.
