Overview:
YBX3 series flameproofthree-phase asynchronous motor (frame No. 63-355), acording to GB3836.1-2021 "Explosive Environment Part1: equipment, general requirements" and GB3836.2-2021 "Explosive Environment Part 2: equipment protected by explosion-proofenclosure" and MT451-2011 "General Technical Specification for safety performance of explosion-proof low-voltage three-phaseasynchronous motor for coal mine" , the isolation type was made. The explosion-proof mark is: Exdbl GB, ExdbllBT4 GB. The utility modelis suitable for use as general power eauioment on fixed eoulpment (Exdbl GBl in coal mine underaround containing methane or coal dusor on equipment in places containing Class ll A, class BT 1-t 4 groups (Exdbl GB, Exdbl BT 4GB) combustible gas or explosive mixture ofvapor and air.
Scope and conditions of use
3.1Application of common combustible gas,steam level,temperature levelfor example see table
3.2 Conditions of use 3.2.1Ambientair temperature varies with the seasonsbut does not exceed 35°C-LRB-underground coal mine) or 4C° c (factory),with a minimum ambient air temperature of-1C.°c. 3.2.2 Not more than 1000m above sea level 3.2.3 The maximum relative humidlity of ambient air shall not exceed 95% (when the temperature is 25°C--LRB-RB-(underground coal mine) orthe monthly average maximum relative humidity of the wettest month shall be 90% , and the monthly average minimum temperature shal not excecd 25°c (forfactory use). 3.2.4 Rated voltageis 380V,660V,1140V,380V/660V,660/1140V. 3.2.5 The rated frequency is 50Hz. 3.2.6 The motorrating is based on the continuous working system (s1) as a continuous rating,allowing full-voltage start. 3.2.7 The motoruses F class insulation,stator winding temperature rise (resistance method) by 8oK examination (of which the base number 315L 2,4 oles and,base number355,allowed by 105K examination).
