What specification is needed for the electrical design of general factory buildings?
Plant design standards: industrial plant design must implement the relevant national principles and policies, so as to be technologically advanced, economically reasonable, safe and applicable, ensure quality, and meet the requirements of energy conservation and environmental protection.
Electrical equipment consists of two parts: power supply and electrical equipment. The power supply includes storage battery, generator and its regulator. The electrical equipment includes the starting system of the engine and the lighting, signal and instrument of the automobile, as well as the ignition system of the engine in the forced ignition engine.
The requirements of electrical design of microelectronics factory building mainly include the following aspects: power supply: power supply needs to meet the requirements of stability, reliability and safety, generally using two-way power backup or uninterruptible power supply (UPS) to ensure that microelectronics production is not affected by power failure.
Transformer room, distribution room, capacitor room, etc., shall be provided with facilities to prevent rain, snow, snakes, rats and small animals from entering the room through daylighting windows, ventilation windows, doors, cable ditches, etc. The power distribution room with a length of more than 7m should have two exits and should be arranged at both ends of the distribution room. When the length is more than 60m, an outlet should be added.
In short, the design should be carried out in strict accordance with the “Code for Design of low Voltage Distribution” and various factors should be fully considered to ensure the safety and reliability of power supply. Reduce the outlet circuit of the low voltage cabinet.
Design Essentials of Industrial Lighting
1. The basic elements of lighting design are as follows: illuminance determination: illuminance standard for industrial buildings is determined according to “Industrial Enterprise Lighting Design Standard” TJ34-79; illuminance for civil buildings, before the national standard is promulgated, it should be selected according to the “Technical regulations for Building Electrical Design” according to the use requirements.
2. Article 0.3 the lighting design of industrial enterprises shall not only abide by this standard, but also comply with the requirements of the relevant national standards and norms. Chapter II Lighting methods and Lighting types Article 0.1 Lighting methods can be divided into general lighting, zonal general lighting, local lighting and mixed lighting.
3. For industrial applications that do not pay much attention to dimming function, high temperature environment and high reliability, electrolytic capacitor design is not recommended.
4. The illuminance standard values of industrial enterprises should be classified according to the following series: 0.130, 50, 7100, 150,200,300,500,750,1000, 1500, 2000 and 3000Lx. 2. The standard value of lighting design should be the average illuminance value on the working surface of the production site.
What is the lighting brightness standard of the factory building?
The standard values of illuminance in different places vary from 50lx~750lx. Please refer to the “Building Lighting Design Standard” GB50034-2004 illuminance specification, you can get the place illuminance standard value you want.
-750. The lighting of 12-meter factory building is suitable for 1500-750lumen, and the lighting brightness standard for ultra-precision operation, design, drawing and precision inspection is 3000-1500. The luminance standard of design room, analysis, assembly line and painting lighting is 1500-750.
According to different workshop functions and environmental requirements, workshop lighting brightness standards are also different. At present, the national standard stipulates that the lighting brightness of the workshop is not lower than that of 150lux, while for some processes that require higher light, such as precision assembly, inspection, etc., the lighting brightness is not lower than 500lux.
There should be sufficient natural lighting or artificial lighting in the workshop or work place. The lighting coefficient of the workshop should not be lower than the standard IV, the mixed illuminance of the working face of the inspection place should not be less than 540lx, the working face of the processing site should not be less than 220lx, and other places should not be lower than 110lx.
The illuminance standard values of industrial enterprise lighting should be classified according to the following series: 0.130, 50, 7100, 150,200,300,500,750,1000, 1500, 2000 and 3000Lx. 2. The standard value of lighting design should be the average illuminance value on the working surface of the production site.
Standard: ultra-precision operation, design, drawing, precision inspection lighting brightness standard 3000 to 1500. The brightness standards of design room, analysis, assembly line and painting lighting are 1500 to 750. Packaging, metering, surface treatment, warehouse lighting brightness standard 750 to 300.
