Unified Provisions on the Depth of Contents of Construction Drawings for Electrical Design in Chemical Enterprises
HG21507-92
Electrical Design Technology Center Station of the Ministry of Chemical Industry, First Design Institute of the Ministry of Chemical Industry
These regulations were proposed by the Electrical Design Technology Center Station of the Ministry of Chemical Industry, issued by the Infrastructure Department of the Ministry of Chemical Industry, and prepared by the First Design Institute
These regulations are applicable to the construction drawing design of large and medium-sized projects in chemical enterprises. For small enterprises or renovation projects of old enterprises, they can be appropriately simplified. For major foreign-related projects or foreign aid designs, they can be deepened accordingly when necessary.
This regulation is mainly based on the power supply, distribution and lighting commonly used in chemical electrical design, but the relevant detailed drawings (construction drawings are not included.
This regulation is revised on the basis of the original CD90A1-81. In this revision, there are major changes in combination with the needs of development.
After the promulgation of the new national standard, the Second Design Institute of the Ministry of Chemical Industry compiled the "Unified Regulations on Graphic and Text Symbols for Electrical Design of Chemical Enterprises", which should be followed in this regulation, but because the Chinese characters in the national standard are not enough, a part is supplemented. In order to adapt to the needs of development and facilitate international exchanges, the drawing format and representation method are different from the provisions of CD90.A11-81.
On the premise of adopting the equipment order specification, the content of the equipment table is appropriately simplified. 4.2.1
The revision adds a cable panel table, which is manufactured! The panel is returned to the construction unit, which is conducive to the construction 4.2.2 coke
on-site management and use.
4.2.3 Secondary circuit diagram There are more than two ways of representation. This time, power supply and distribution are represented in two different ways respectively, in order to provide two ways for the project to choose. In the specific project, one way or both ways can be specified.
4.2.4 The representation of the terminal table, power supply and distribution are also two different ways, either two ways coexist or one way is specified.
Preparation instructions
4.2.5 The civil engineering condition drawing of the substation was added in the revision, which is conducive to on-site construction. 1.3
In order to adapt to the future computer-aided design, in terms of the drawing size, computer drawing has been considered. This regulation only stipulates the design content, depth and expression method. There is no relationship between the drawings, and they are not used as the basis for determining the scheme and technical economy in the design. The participants in the preparation are Liu Guisheng, Wang Xijue, Fan Changqi, Wang Dazhi, Ye Wenjie, Shen Junhan, etc. Due to the time constraints and level limitations during the preparation process, please give more valuable suggestions for errors and inappropriateness.

Part II of the District Power Supply Center and Substation Preparation Instructions (I) Preparation of this Several Principles of the Present Regulations
1 Graphic and text symbols shall be based on the Ministry of Chemical Industry's "Graphic Symbols for Electrical Drawings" and "General Rules for the Formulation of Text Symbols in Electrical Technology" 1.1 Graphic symbols in circuit diagrams, blood designed as a network system with a specific module, the module used is M=2.5mm. 1.2 The length of the rectangle side and the diameter of the circle should be designed as multiples of 2%. For smaller symbols, 1.5m, 1.0m, and 0.5m are used. 1.3 The distance between lines is at least 2m to meet the requirement of 2.5mm minimum character height. 1.4 Regardless of the size of the symbol, the point should be at the intersection of the network. 1.5 The length of the connection between the horizontal and vertical elements should be appropriate. According to the size of the drawing, the M multiple should be appropriately determined. The midpoint of the graphic symbol coincides with the midpoint of the network. This line can also be used. When the line distance is 3M, 5M, 7M, etc., use 2. The drawings in this compilation are not related to each other (except for those noted), and are not used as the basis for design technology and solutions. People's Republic of China

3When two or more different expressions appear in the drawings, one can be selected [This now recommends the first one (A)]4 Civil engineering drawings are added to this compilation. The purpose is to benefit both the design and construction personnel, to improve the design quality and to cooperate with civil engineering construction. Therefore, it is stipulated that the formal construction drawings must include civil engineering drawings. Each institute can determine the degree of simplicity of the case according to the project situation and requirements (the country can archive it, but it will not be found on site)5 Notes on references in drawing:

Line numbering and marking method
()Text labeling method for flat flip equipment For example: High-voltage switchgear, with AH, multiple cabinets are AH1, AH2...AHn. The low voltage switch panel is named with AA, and multiple cabinets are named with AA1, AA2, etc. AAn. The motor is named with the process position number, such as B103A, B10.3B, etc. For other boxes, columns, and tables, please refer to the Chinese character symbols in this compilation. (II) Internal line marking method
2.1 For example: AHI high voltage switch cabinet to B103A high voltage motor power cable is marked with AH1-B103A, and its control cable is AH1-B103AC2.2 The lines in the workshop are named with the equipment position number. The main circuit and control circuit are named with the equipment position number, such as: motor position number B103A
fan pull number
2.3 External lines: (high voltage equipment)
Main circuit B103A
Control circuit B103AC
Main circuit S-1
Control circuit S-1C
Between substations: Example 1AH 01-24H05, indicates the No. 1 high-voltage switchgear of 1# substation to the No. 5 high-voltage switchgear of 2# substation.
Between high-voltage switchgear and electrical equipment: For example, 1AH 02-ITM01, indicates the No. 2 high-voltage switchgear of 1# substation to the No. 1 transformer of 1# substation, AH 03-P101A indicates the No. 3 high-voltage switchgear of 1# substation to the P101 high-voltage motor,
2.4 Lighting circuit
For example, the U phase of the third circuit of the No. 1 lighting distribution box is represented as AL1-U3. Note: The voltage busbar numbers listed in the table are applicable to the situation where there is only one voltage in the substation. If there are several different voltage levels,Different numbers can be used before the letter mark of the motherboard to distinguish them. Phase sequence marking
1) Marking of specific conductors:
Power supply of AC system
Power supply of DC system
(2) Phase sequence marking of electrical equipment terminals: AC system
