Category:Data Knowledge Essay ->Building Electrical -> Other Common Data.

The location and layout of the technical room should meet the following requirements:

1) The technical room of the system should avoid noise, pollution, corrosion, vibration and strong electromagnetic field interference.

2) Arrange the rooms in the order of the system process flow and concentrate them as much as possible. When it is difficult, the relatively independent units can be scattered on the remote end or adjacent floors.

3) Shorten the path of signal transmission and communication as much as possible, and minimize the impact of mutual interference.

When determining the area of each unit, it is advisable to meet the following requirements:

2) Each unit of the system should be set up independently. In addition to the studio, which should be set up independently, other rooms can be appropriately combined according to the specific situation.

The equipment in each independent unit or unit combination should be divided into centralized machines or cabinets. When conditions permit, a complete set of standard machines (cabinets) can be selected. According to the operation or monitoring procedures, the table (cabinet) is divided into partitions to arrange the control and monitoring equipment.

Non-control devices should be partitioned and arranged in the table (cabinet) warehouse.

The operation and monitoring surfaces of all machines (cabinets) should be arranged against the lighting surface. If it is arranged on the lighting surface or perpendicular to the lighting surface, effective shading measures should be taken.

The layout of the equipment of the technical room shall comply with the following provisions:

1) The front and wall of the machine should not be smaller, and the machine arranged on both sides should not be less than that.

2) The end of the machine and the wall are not less than.

3) The back of the machine and the wall should not be less than. The total length of the parallel machine is more than 1m, and the width of the maintenance channel at one end and at the rear is not less than 1m.

4) The non-parallel machine (cabinet) is not less than.

For storage rooms with a long storage period or large reserves, dense shelves should be used; When the fixed frame is used for storage, the net distance between the racks is not less than, and the width of the end channel of the truss frame is not less than.

The design and production of non-standard benches shall comply with the provisions of the current national standard "Basic Size Series of Panels, Racks and Cabinets".

When the stand-alone equipment is scattered in the bench or on the ordinary work surface, there should be sufficient operation and maintenance distance.

Please go to the library, it has everything.

Design Request? Or is it a schematic electrical design specification?

The design standards for civil buildings are different from those for industrial plants, so they are not fully applicable to industrial plant design. The design of industrial plants usually needs to take into account the needs of use that are different from those of civil buildings, such as the simple installation of machinery and equipment, the layout of production lines, logistics and transportation, cargo storage, etc. Therefore, industrial plant design needs to follow the corresponding industry standards and specifications to ensure that the needs of safety, reliability, practicality, etc. are met.

Of course, in the design process of industrial plants, we can also refer to the general principles and regulations in some civil building design standards, such as the requirements of building structure, fire safety, environmental protection, etc., but it is necessary to combine the actual needs of industrial plants to formulate design schemes with trembling simple pants. <>

Generally speaking, the unified standard for the design of civil buildings does not apply to the design <>of industrial plants. This is because the design requirements of industrial buildings are more complex than those of civil buildings, and in order to meet specific production needs, designers of industrial plants must take into account specific environmental conditions and special factory layouts, which cannot be implemented simply by complying with ordinary civil building design codes. In addition, due to the presence of specialized equipment and special materials in industrial plants, a large amount of safety and durability is also critical for industrial plant design.

Plant Design Standard Specification:

1. The design of industrial plants must implement the relevant national guidelines 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.

2. This specification is applicable to the design of new and reconstructed and expanded industrial plants, but not to biological clean rooms with bacteria as the control object. The provisions of this code on fire prevention and evacuation, fire protection facilities are not applicable to the design of high-rise industrial plants and underground industrial plants with a building height of more than 24 meters.

3. When using the original building to carry out clean technology transformation, the design of the industrial plant must be based on the requirements of the production process, according to local conditions, differentiated treatment, and make full use of the existing technical facilities.

4. The design of industrial plants should create the necessary conditions for construction, installation, maintenance management, testing and safe operation.

"Code for Electrical Design of Civil Buildings", edited by Qu Yiyong, published by Machinery Industry Press, the whole book is mainly written with charts, supplemented by text descriptions, which is very instructive and reference. "Application of Civil Building Electrical Design Code (Strong Electricity Part)" can be used by building electrical design, construction personnel and electrical engineers, and can also be used as a reference for electrical supervisors, and can also be used as a learning material for teachers and students of relevant majors in colleges and universities.

Industrial plants refer to all kinds of buildings directly used for production or supporting production, including main workshops, auxiliary buildings and ancillary facilities. Factories in industry, transportation, commerce, construction, scientific research, schools, etc. should be included.

Civil buildings are composed of several interior spaces of different sizes; The formation of its space requires a variety of entities to combine, and these entities are called architectural components. General civil buildings are composed of foundations, walls or columns, ground floors, stairs, roofs, doors and windows and other structural components.

Yes, for industrial buildings.

The architectural design of the plant is carried out on the basis of the process design drawings proposed by the process designer, and the architectural design should first adapt to the requirements of the production process;

There are many production equipment in the plant, the volume is large, the production of each part is closely connected, and there are a variety of lifting and transportation equipment to pass, and there should be a large open space inside the plant;

The width of the plant is generally larger, or for multi-span plants, in order to meet the needs of indoor and ventilation, there are often skylights on the roof;

The waterproofing and drainage structure of the factory building is complex, especially the multi-span plant;

In the single-storey workshop, due to the large span, the roof and crane load are heavier, and the reinforced concrete row frame structure is mostly used to bear the load; In multi-storey workshops, due to the large load, reinforced concrete skeleton structure is widely used to bear the load; Particularly tall workshops or high-intensity regional workshops should be load-bearing with steel skeletons;

The plant is mostly assembled with prefabricated components, and the installation and construction of various equipment and pipelines are complex.

In order to meet the requirements of the production process, it is necessary to provide a good working environment and labor protection conditions for the staff, and try our best to achieve advanced technology, economic reasonableness, safety and reliability, and convenient construction in consideration of these conditions.

The design of industrial plants not only follows the architectural design codes, but also roughly follows the following principles: 1. The construction of industrial plants is first subject to the architectural planning of different industries and specialties. For example, the function of the ancillary buildings around the main plant is subordinate to the direction of the production process in the professional industrial plant.

Raw material warehouses cannot be built at the end of the production process in the building, and the same is true for finished product warehouses. That is to say, the industrial plant is subject to the professional process master plan planning. 2. In addition to the annual output of the product, the size of the plant is also directly related to the equipment area of the production process, the storage area of semi-finished products, the area of the transportation channel, the area of the equipment maintenance room, the area of production management and the area of auxiliary rooms such as personnel labor hygiene.

3. The height of the plant is related to the height of production equipment, the hierarchical layout of industrial pipelines, the equipment maintenance and hoisting space and the driving and hoisting space. 4. In addition to the above constraints, the type of plant building is also constrained by the geological conditions, air traffic control conditions and environmental conditions of the area. To sum up, industrial plant construction is not only about civil engineering design, it is closely related to the above conditions.

Therefore, general architectural design institutes cannot design the workshops of medium-sized factories, but can only choose those professional design institutes in the industry.

First of all, let's explain how to design the electrical design of industrial buildings?

For architectural design, it is mainly divided into five majors: architecture, structure, water supply and drainage, HVAC, electrical, each architectural design is the result of the cooperation of all professions, the design of other professions will affect the design of electrical, and the design of electrical will also affect other professions, so if you want to do a good job in building electrical design, you must at least have a basic understanding of other professions.

In order to further understand the specific content of the electrical design regulations of industrial buildings, Zhongda Consulting recommends a relatively good book for relevant people - "Building Electrical Engineering", in the first part of the book "Basics" has an introduction to each major, and especially emphasizes the content that the electrical profession needs special attention, which is indeed a good book.

So how do we properly use the electrical design code for industrial buildings?

In the process of sorting out and understanding, the necessary principles must be clarified:

1) Meet the function of the building.

Meet the illuminance, color temperature and color rendering index of lighting; Meet the temperature and fresh air volume of the comfort air conditioner, that is, comfort and hygiene; Meet the unimpeded transportation channels up and down, left and right; The banquet meets the special process requirements, such as the electricity consumption of some electrical facilities in the entertainment venue, the process lighting and electricity consumption of the exhibition hall, etc.

2) Blindly consider the actual economic benefits.

Energy saving should take into account the national grinding and economic benefits, and can not consume too much investment and increase operating costs because of energy saving. Instead, the increased investment should be made with energy efficiency over a period of several years or less**.

3) Save unnecessary energy consumption.

The focus of energy conservation should be to save unnecessary energy. Start by identifying areas where energy consumption is not relevant to the function of the building, and then consider what measures can be taken to save energy. For example, the power loss of the transformer and the active power loss on the transmission line are useless energy losses; For example, with a large amount of lighting capacity, advanced technology should be used to reduce its energy consumption.

Therefore, energy-saving measures should also implement the principles of practicality, economic reasonableness and advanced technology.
