Scope

Scope: This standard specifies the types, basic parameters, dimensions, technical requirements, test methods and inspection rules, as well as marking, packaging, and warranty period requirements for YBBP3 series explosion-proof high-voltage frequency-controlled three-phase asynchronous motors (with frame numbers 355 to 630). This standard applies to YBBP3 series explosion-proof high-voltage frequency-controlled three-phase asynchronous motors (with frame numbers 355 to 630) (hereinafter referred to as "motors"). All motor series derived from this series can also refer to and implement this standard accordingly. Main technical content: The efficiency values specified in this standard are higher than the Class 2 energy efficiency values stipulated in GB 30254-2013 "Energy Efficiency Limits and Classification for High-Voltage Three-Phase Cage-Type Asynchronous Motors", and some specifications reach Class 1 energy efficiency values. The efficiency of 6 kV motors is determined according to the E method or E1 method specified in GB/T 1032-2012; for motors with a rated power of more than 1,000 kW, the efficiency is determined according to the H method specified in GB/T 1032-2012, and their stray losses are calculated according to the recommended values. For motor powers not mentioned in GB 30245-2013, their corresponding efficiency values are increased based on the actual calculated values. GB 30245-2013 does not stipulate 10 kV energy efficiency values. The 10 kV motor efficiency values are calculated based on the energy efficiency values in GB 30254-2013 through a comparison of a large number of experimental values. The YBBP3 series explosion-proof high-voltage frequency-controlled three-phase asynchronous motors are designed with the goals of protecting the environment, ensuring reliability, and meeting user needs. They incorporate modularization, universalization, and standardization design methods into the product, featuring compact structure, high efficiency, small
