This standard is a revision of the JB3752-84& method for compiling product models of electric control equipment. It not only maintains the consistency of the use of the original product model, but also takes into account the needs of continuous product development. The naming of product models in this standard is mainly based on the industry unified naming method, and also considers the naming method of enterprises on their own, so as to maintain the uniformity of product naming and reflect the autonomy and exclusive right of manufacturing enterprises. The implementation of this standard will make the naming of models of electric control equipment products in my country more standardized according to varieties and specifications, which plays an important role in the production, use, cooperation and maintenance of products.
This standard was revised with the addition of the scope of Chapter 1 and the notes in Chapter 3. JB/T3752 includes the following parts under the general title of the method of reducing the product model of low-voltage complete switchgear and control equipment: Part 1 (i.e. JB/T8752.1): Low-voltage transformation and switching equipment: Part 2 (i.e. JB/T3752.2): Electric control equipment. This standard will replace JB3752-84 from the date of implementation. Appendix A of this standard is a prompt appendix.
This standard was proposed and managed by the Technical Committee for Standardization of Electric Drive Complete Control Equipment: Drafting unit of this standard: Tianjin Electric Drive Design Institute. Main drafters of this standard: Dong Baosheng, Zhu Chunjuan, Luo Chong. I

This standard specifies the method for compiling the product model of general electronic control equipment and special-purpose supporting standardized electronic control equipment. This standard applies to the compilation of the product model of general electronic control equipment and special-purpose supporting standardized electronic control equipment. 2 Model naming principles
2.1 The naming of product models should be concise
2.2 The full model of the product must represent only one product and should not be mixed or repeated. JB/T3752.21999
JB37521984
2.3 The product model consists of uppercase Chinese phonetic letters (hereinafter referred to as letters) and Arabic numerals (hereinafter referred to as numbers). 3 Product model naming
The full model of the product consists of five parts: category code, series code, variety number, specification number and additional code. Its specific composition is as follows;
口O口
Additional code
Specification number
Variety numberbzxz.net
System design serial number
Series characteristic code
Category code
Note: Enterprises can add codes of different manufacturers as special models of their products according to the characteristics of the products they develop, or according to the product model naming method. However, this requirement must be applied by the enterprise and filed with the industry unit to avoid confusion and duplication. 4 Meaning of the code in the model
4.1 Category code: divided according to the scope of use of the product or the category of the motor controlled, the meaning of the code is shown in Table 1. WA Extremely Slow 1999-08-06 Tumor

The second combination: special machine matching standard electric control equipment DL—Elevator magnetic electric control equipment; Qz—Power brake speed control electric control equipment for lifting machinery; WS—DC speed control electric control equipment for excavators, JK—AC control electric control equipment: AR—Electric control equipment for other machinery.
4.4 Variety number: In a series of products, its varieties are divided according to the system electrical strategy or other basic characteristics. The variety number is represented by a letter. The letter is not given a fixed meaning in advance and can be arranged in sequence from "A\" according to the specific situation of each series of products. 4.5 Specification number: It represents the main parameters of the electric control equipment, such as: current, voltage, current/voltage, power, etc. If necessary, it can be represented by the main parameters and types of supporting machinery.
4.6 Additional code: In a variety, when it is necessary to represent its different auxiliary characteristics or in a set of electric control equipment, additional codes can be used to represent its various components. Additional codes can be represented by letters or numbers. The letters and numbers are not given a fixed meaning in advance and can be Arranged according to the specific situation of each series of products, generally with no more than two letters or two digits. For examples of product model compilation, see Appendix A (suggestive appendix). 5 Special requirements
