| 隔爆型锥形转子电动机是我厂最新设计的IIB、IIC级防爆电机。 BZD系列电机主要作为防爆电动葫芦的起升电动机和防爆电动卷扬机及其它设备的带制动动力之用。BZDY系列电机主要作为防爆电动葫芦的运行电机和单梁行车的驱动装置配套之用。 BZD系列和BZDY系列电动机按国家标准GB3836．2-83《性环境用防爆电气设备隔爆型电气设备“d”》的要求，制成隔爆型，防爆标志dII BT4、dII CT4，适用于工厂具有级别IIB、IIC级，温度组别T1～T4组的可燃性气体、蒸气与空气形成的性气体混合物的场所。 电动机工作制为S4，基准负载持续率为25%，每小时等效起动次数为120次。 额定电压： 380V 额定频率： 50Hz 防护等级IP44或IP54 | |||
| The motor with conic rotor is the lateat IIB and IIC one designed byour works. The BZD range of motors is used as the lifting motor of explosion- proofelectric hoist and the driving equipment of explosion- proof windingengine and other machinery. The BZDY range of motors is as the runmotor of explosion-proof hoist or matched with the driving device ofsingle carrier. The explosion-proof characteristic GB3836.2-2000 << Flame-proof "d"- - ElectricalApparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type. This range ofmotors, whose explosive marking is dI, dIIAT4, dIIBT4 and dIICT4, canrespectively used in places where there are flammable gas and themixture of the vapour and air in the coal minging and factory wherethe protection degree is IIA,IIB or IIC and temperature is T1-T4. Duty type is S4 whose the basic load continuity is 25% and theequivalent starting times is 120 every hour. Rated voltage: 380V. Rated frequency: 50Hz. Protection grade: IP44 or IP54. | |||
