通俗地讲，电线万一失火，能够把燃烧限制在局部范围内，不产生蔓延，保住其他的各种设备，避免造成更大的损失。阻燃电缆概述阻燃电缆的含义：在规定试验条件下，试样被燃烧，在撤去火源后，火焰在试样上的蔓延仅在限定范围内并且自行熄灭的特性，即具有阻止或延缓火焰发生或蔓延的能力。

变频器输入侧功率因数低，是因为线路中存在高次谐波造成的。在电流的有功分量相等的情况下，相位角越大，无功电流就越大，这样铜损越大。1变频器输入侧功率因素低，主要原因是电路中存在高次谐波电流，增加补偿电容，在电网容量较低时，更容易出现电压的脉动，有可能损坏补偿电容。1单就改变功率因素来讲，直流电抗器优于交流电抗器。但是交流电抗器可以削弱冲击电流。（直流电抗器用在直流侧，目的是将直流电流中的交流部分稳定在某范围内，使直流部分连续，减少直流脉动。
