T/CCS 031-2023 Mine flameproof and intrinsically safe integrated VFD motor
Basic Information
Scope
This document specifies the terms and definitions, types and basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of explosion-proof and intrinsically safe variable-frequency speed-regulating all-in-one machines (hereinafter referred to as "all-in-one machines") for mining use.
This document is applicable to explosion-proof and intrinsically safe variable-frequency speed-regulating all-in-one machines for mining use in environments with the explosive risks of methane and coal dust, and with operating characteristics of two-quadrant or four-quadrant operation. These machines are used as prime movers for belt conveyors, emulsion pump stations, reloaders, scraper conveyors, and other equipment.
