在机车正常情况下: 1.调压开关本身分级转换开关有限位装置,使主凸轮轴最大只能转340°,其辅助联锁的开距为6—9mm,CD与减速箱之间装有磨擦耦合器(其打滑转矩为0.34—0.4kgm),且CD选择了制停性能良好的直流电机。 2.从R_(84)本身看,R_(84)设计7Ω,1000W,额定电流为11.95A,而CD回路的起动电流≤10A,连续升退级电流≤5A;CD的堵转电流<15A,且R_(84)为断续工作制,TK从零级升到33级或从33级降到0级≤225,又由于《操作规程》的第25条限制,R_(84)的实际连续得电时间≤11S。
In the normal locomotive: 1. The pressure switch itself has a level switch limit device, the main camshaft can only rotate the maximum 340 °, its auxiliary interlocking distance is 6-9mm, between the CD and the gearbox Friction Coupler (with a slip torque of 0.34-0.4kgm), and the CD selected a DC motor with good stopping performance. 2. From R 84 itself, R 84 is designed with 7Ω, 1000W and rated current 11.95A, while the starting current of CD loop is less than or equal to 10A, the current of continuous rising and falling is less than or equal to 5A, the blocking current of CD is less than 15A, And R 84 is intermittent working system, TK rises from zero level to 33 level or from 33 level to 0 level ≤ 225, and due to the restriction of Article 25 of “Operational Rules”, the actual continuous of R_ (84) Electric time ≤ 11S.
