1 Subject content and scope of application
JB/T31391991
This standard specifies the compilation method of type guide for explosion-proof electrical appliances and general electrical appliances. This standard applies to mining and general flameproof devices (including low-voltage explosion-proof electrical appliances, commercial-voltage explosion-proof electrical appliances, explosion-proof electric control equipment) and general electrical appliances for mining.
2 Definition
New products
Compared with old products, they have obvious improvements in one or more aspects of structure, material, and process, or adopt new technology principles and new design structures, thereby significantly improving product functions, that is, products with major technological breakthroughs. 3 Product classification
Explosion-proof electrical appliances and general electrical appliances for mining include the following twelve categories: circuit breakers,
starters
relays:
master electrical appliances;
dynamic electrical appliances:
plug-in electrical appliances
junction boxes:
protective devices:
commercial electrical appliances Pressure switch,
Electronic control equipment;
「, other categories.
4 Method for compiling product models
4.1 Compilation principles
,1.1 Product models are represented by uppercase Chinese phonetic characters and Arabic numerals. Table 1.2 Chinese phonetic letters should be selected according to the following principles: a, the first Chinese phonetic letter in the product name is used, b, if the above letters cannot be used in the model, the first letter of the second Chinese phonetic letter can be used: ℃. If there are difficulties, other letters can be used. 4.2 Overall composition of product models
4.2.1 Product models represent a series of products of a certain type. The combination of the category group code and the design code represents the series of products. 4. 2.2 The full model of a product represents the series, variety and specification of the product, that is, the variety code (such as current, voltage or capacity value, etc.) and other alphanumeric characters are added after the product model to determine the main specifications and vortex characteristics of a product.

Variety number
Use three Chinese pinyin characters to represent The product name is indicated. The category code is shown in Table 1 and Table 2. 4.3.2 Design code
Special environment code
is indicated by Arabic numerals. The design codes of general electrical products for mining explosion-proof devices are 1-49, the design codes of factory gas explosion-proof electrical products are 51-09, and dust explosion-proof electrical products are arranged from 101 onwards. 4.3.3 Variety code
is indicated by Arabic numerals, with unlimited digits, determined according to the main parameters of each product, generally indicated by current, voltage or capacity, etc. 4.3, 4 Series derived code or feature code uses a Chinese phonetic letter to indicate the characteristics of product changes within the series, and the code is shown in Table 3. 4.3.5 Specification code
uses digits (unlimited digits) to indicate product features that need further explanation. Such as the number of connections of the junction box, etc. 4.3.6 Special environment code
indicates the special environment that the product can adapt to, the special environment of explosion-proof electrical products, and the code is determined according to Table 4. There is no such code for dust explosion-proof electrical appliances and general electrical appliances for mining.
