大(da)量非(fei)線(xian)(xian)性(xing)負載使用(yong)會(hui)導致(zhi)中(zhong)(zhong)性(xing)線(xian)(xian)3N次諧波電(dian)(dian)流過大(da)，同時，三相不平衡(heng)等問題往往也會(hui)造成(cheng)中(zhong)(zhong)性(xing)線(xian)(xian)電(dian)(dian)流過大(da)。而(er)中(zhong)(zhong)性(xing)線(xian)(xian)電(dian)(dian)流過大(da)非(fei)常容易導致(zhi)中(zhong)(zhong)性(xing)線(xian)(xian)絕緣層老化(hua)起火(huo)(huo)引(yin)發火(huo)(huo)災(zai)，存在較(jiao)大(da)的(de)安全隱患(huan)。針對這樣的(de)情(qing)況，我司(si)采用(yong)*電(dian)(dian)力電(dian)(dian)子技術、控制理論等研制出(chu)了新型的(de)中(zhong)(zhong)線(xian)(xian)安防(fang)保護(hu)器，可有效消除中(zhong)(zhong)性(xing)線(xian)(xian)電(dian)(dian)流過大(da)的(de)情(qing)況而(er)造成(cheng)的(de)電(dian)(dian)氣火(huo)(huo)災(zai)安全隱患(huan)。
