工作条件 环境空气温度随季节而变但不超过-15℃~40℃ 海 拔: 不超过1000m 频 率: 50Hz/60Hz 电 压: 220V~690V 工作方式: 连续(S1) 起动方式: 满压起动、Y-△起动或电抗起动 传动方式: 可采用弹性联轴器或正齿轮传动绝缘、升温:F级。但定子绕阻温升限值80K,即按B级考核(电阻法)。轴承允许温度不超过95℃(温度计法)。 冷却方法: IC411 | Working conditions
Ambient temperature:to be altered with the change of seasons, but do not exceed -15℃ ~40℃ Altitude: to be used lower than 1,000 meters above sea level. Rated frequency: 50Hz/60Hz Rated voltage: 220V~690V Duty: Continuous ( S1 ) Method of Starting can be started on full voltage motors and can be started with Y-△ starter or reactor. Driving method: flexible coupling or spur gear can be used for driving. Insulation and temperature rise: class F. But the temp. rise of the stator windings is limited at 8OK, i.e. treated as class B (resistance method). Permissible working temp. of bearing should not be over 95℃ (thermometer method). Cooling method: IC 411 |
