Electrical design and construction drawing of speech lab

Building function: scientific research, Number of sheets: 11 sheets, Strong current design: low-voltage distribution , electrical lighting, relay protection, electrical control

This set of drawings is the electrical diagram of P3 laboratory, including lighting; distribution; Primary and secondary control schematic diagram of one in use and one standby water pump; Primary and secondary control schematic diagram of one working and one standby exhaust fan; Control schematic diagram of AHU1 air conditioning unit; Schematic diagram of electric heating control of air conditioning unit, etc.

1. The electrical construction drawing design of the project includes lighting, lightning protection and protective grounding, telephone and cable television.

2. The load level of the building is Level III power supply. The power supply is led from the outdoor box transformer in the campus to 380/220V. The buried depth of the cable is 0.8m. Repeated grounding and protective grounding should be made at the place where the building enters. The grounding resistance is less than 1 ohm, which is shared with the lightning protection grounding system. The emergency lighting adopts the storage type emergency lighting, and the emergency lighting time is not less than 30 minutes.

3. Line laying: copper core plastic insulated conductor BV-500V is selected for general lighting lines, and it is laid in FPC pipes in a concealed manner. During construction, the route can be properly adjusted according to the actual situation.

This drawing is the electrical cad design and construction drawing of a regional basic course laboratory, including the lighting plan of each floor, broadcast, security and fire protection electrical drawing, weak current plan, construction instruction drawing, potential connection plan, plan, security plan, building layout, socket plan, roof lightning protection plan, air conditioning plan, etc., which can be downloaded for reference.
