ExdⅡBT4 适用于工厂用Ⅱ类 B 级,温度组别为 T1、T2、T3 和 T4 组的爆炸性气体混合
“ExdⅠ” --- safe for use in the non- mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present.
“ExdⅡAT4”--- safe for use in plants where the explosive mixtures of ⅡA Class, TI, T2, T3 or T4 are present.
为使电动机安全可靠运行,机座号 160 及以上电动机轴承结构设置有注排油装置,机 座号 250 及以上电动机,预留轴承温度监测传感元件位置。
2.10 电动机风扇、风罩:机座号 280 及以下电动机采用防静电塑料风扇,其转动惯 量小、损耗低,机座号 315 及以上采用铸铝或钢板焊接风扇,重量轻、强度高,全系列风 扇与轴采用键联接,运行可靠。风罩为钢板结构,在防止一定大小的外物侵入的前提下得 到最大的通风面积,使风路通畅。
2.5 A cylindrical shaft extension is equipped on motors, which is driven by coupling or spur gearing.
2.6 The stator windings are wound with polyester enamel round wire of high strength and then treated with the progress of vacuum-pressure impregnation (VPI), to make them become a solid integral. Therefore, the winding insulation is excellent in electrical and mechanical properties, moisture resistance and thermal stability.
