Yb3 series explosion-proof three-phase asynchronous motor is used to contain methane or coal dust in coal mine (non mining working face) (ex I d) and plant (ex D II at4, D II BT4) contains a class II, formation of group B class T1-T4 flammable gas or vapor and air mixture explosive field.

环境温度为-15℃~35℃(煤矿井下)或-15℃~40℃(工厂)

The temperature of the environment is -15 (the coal mine) or ~40 (the factory) at -15 for the ~35 (the coal mine) at the temperature of the environment

特点是:防爆标志为ExdⅠ、Ex dⅡAT4、d ⅡBT4,Ⅰ类的最高表面温度不超过150℃(当电机表面可能堆积煤尘时),不超过450℃(当电机表面不会堆积或采取措施可以防止堆积煤尘时);Ⅱ类的最高表面温度应不超过:T1(450℃)、T2(300℃)T3(200℃)、T4(135℃);接线盒可分别制成三个或六个出线端子,适用于橡套电缆(或塑料电缆)和钢管布线两种结构。

Features: explosion proof mark Exd I, ex D II at4, D II BT4, class I, the maximum surface temperature not exceeding 150 DEG C (when motor surface may accumulate dust), not more than 450 DEG C (when the surface of the motor will not accumulate or measures can be taken to prevent the accumulation of coal dust); class II of the maximum surface temperature shall not exceed: (450 DEG C) T1, T2 (300 DEG C) and T3 (200 DEG C), T4 (135 DEG C); junction box can be respectively made into three or six terminals for rubber sheathed cable (or plastic cable and steel pipe wiring structure.
