　　本厂电缆含税，全国免费送货。矿用阻燃铠装通信电缆阻燃性能：矿用通信电缆引发火灾的原因，主要是因为过负荷、短路、接触电阻过大及外部热源作用。在短路、局部过热等故障状态及外热作用下，绝缘材料绝缘电阻下降、失去绝缘能力，甚至燃烧，进而引发火灾。

主回路，就是输入输出而已变频器有单相和三相之分，单相变频器一般是单相220伏供电的，因为国内民用都使用这种单相电压，所以这种单相变频器也迎合而生，理论上接入电源可以广泛点，很多民用的小设备可以使用这类变频器和电机来完成调速。上图上半部就是主回路接线，非常简单，输入有个空气开关断路器之类的器件，给变频器L1和N线供电，变频器输出UVW接电机的UVW端，这样主回路的接线就已经完成了，主回路接线，主要是线比较粗，线头一般都要压上线耳，这样和变频器的端子接触电阻小，保证导电性能良好。

Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also have additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is to use two different shielding materials, on the electromagnetic shielding of going about with each other, the shielding effect will be better.

三个线圈CCCC为Y连接，如用△（三角形）接法也能同样运行。，，A相B相间加电压，两个线圈磁通方向相反如箭头所示。该激磁驱动电路如下图所示。T1~T6为功率管，各相线圈接法，T1~T6的B端为电源端，G端为接地端。T1~T6导通顺序如下表所示，O表示功率管导通，由此给Y接法的3个端子中的两个加正负电压。由于三个线圈的尾端短接，必定使两相绕组顺次激磁，即三相绕组两相激磁驱动。
