- Scope
- JB/T 8674-1997 This standard is formulated based on my country's current standards and explosion-proof regulations for three-phase asynchronous motors. This standard specifies the type, basic parameters and dimensions, technical requirements, test methods and inspection rules of YB series (frame number 355~450) high-voltage flameproof three-phase asynchronous motors, as well as marking, packaging and warranty period requirements. This standard applies to YB series (frame number 355~450) high-voltage explosion-proof three-phase asynchronous motors (hereinafter referred to as motors). All series of motors derived from this series of motors can also be implemented with reference. The explosion-proof performance of this series of motors complies with the regulations of GB 3836.1 and GB 3836.2, and is made of explosion-proof type. The explosion-proof marks are dⅠ, dⅡAT4, dⅡBT4, and dⅡCT4, which are respectively suitable for underground fixed equipment in coal mines and factories of Class IIA, Class IIB, and Class IIC. The combustible gases or steam in the temperature group T1~T4 dare to form explosive gases with air. Mixture place.
