  但是在电缆燃烧时会释放大量的浓烟和卤酸气体,卤酸气体对周围的电气设备有腐蚀性危害需要带上防毒面具才能接近现场进行灭火。电缆燃烧时给周围电气设备以及救援人员造成危害,不利于灭火救援工作,从而导致严重的“二次危害”。

假设以1ma作为光耦的导通电流,那么在220v交流电由0V变化到141V的过程需要1.5ms。而因为期间的一致性问题,部分光耦可能会在0.5ma的时候就导通,部分可能在0.7ma的时候导通。现假设一致性带来的低导通电流为0.5ma,那么对应导通电压为71V,对应滞后零点时间为736us,这表明,不同光耦之间零点差异可能达到764us。(实际测试中我检测了10个样品,其中两个光耦导通性能差别大的时间差达到50us,其他普遍在10us左右)。

  (3)、敷设电缆时的环境温度不低于0℃,低环境温度:固定敷设-40℃,非固定敷设-15℃。(4)、电缆小弯曲半径:非铠装层或编织屏蔽的电缆,应不小于电缆外径的6倍,有铠装或铜带屏蔽结构的电缆,应不小于电缆外径的12倍。

  10、弯曲寿命比普通安装线要长,但不作为拖链电缆使用。●使用特性:1、较低的有效电容2、具有良好的耐火燃烧性能,可用于危险区域3、低传输阻抗。该产品含有屏蔽层,具有较强的抗电磁干扰、抗雷击及均匀电场,改善供电品质特性。

)机械原因引起的振动表现为:电动机轴上有外伸重量,轴系统的固有频率降低时,如果电动机高速运转,全旋转频率与轴系统固有频率接近,则振动加剧。转子残余不平衡引起离心力与转速的二次方成比例增加,所以用变频器驱动电动机高速运转时,振动加大。变频器是电子装置,所以温度对其寿命影响较大。通用变频器的环境温度一般要求-10~+50℃,如果能降低变频器运行温度,就延长了变频器的使用寿命,性能也稳定。变频器发热是由内部损耗产生的,以主电路为主,约占总损耗的98%,控制电路占2%。
