電(dian)(dian)磁線(xian)圈(quan)的(de)低壓(ya)電(dian)(dian)器類別多，應用(yong)廣(guang)，且產量大。電(dian)(dian)工(gong)經常要對這類電(dian)(dian)器電(dian)(dian)磁系統的(de)線(xian)圈(quan)進行(xing)維(wei)修和(he)更換(huan)。因此，簡單地(di)近似計(ji)算和(he)換(huan)算交、直流(liu)線(xian)圈(quan)參數，以便當原線(xian)圈(quan)損(sun)壞或參數（如電(dian)(dian)壓(ya)或工(gong)作(zuo)制等）改(gai)變時，就地(di)取(qu)材(cai)繞制個合(he)乎要求的(de)線(xian)圈(quan)取(qu)代原線(xian)圈(quan)，這是電(dian)(dian)工(gong)應知應會的(de)技能(neng)。本文舉例介(jie)紹(shao)了交、直流(liu)線(xian)圈(quan)參數的(de)換(huan)算和(he)簡化計(ji)算。

電磁線圈主要參數進行整定(ding)、計(ji)算(suan)(suan)和換(huan)算(suan)(suan)的方法。這些(xie)計(ji)算(suan)(suan)和換(huan)算(suan)(suan)方法對其他有(you)觸點直流(liu)電器(qi)同樣適(shi)用。通過這些(xie)計(ji)算(suan)(suan)和換(huan)算(suan)(suan)，可以(yi)使(shi)已有(you)的電磁繼電器(qi)、接觸器(qi)產品滿足(zu)機車(che)上各種不同控制或測量的需要。

電(dian)磁(ci)線(xian)(xian)圈(quan)(quan)(quan)參(can)(can)數的(de)(de)(de)(de)換(huan)算方法: 在(zai)接觸器的(de)(de)(de)(de)使(shi)用和(he)維修中,有時會碰到這(zhe)(zhe)樣的(de)(de)(de)(de)情況,如手中現(xian)有接觸器線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)工作電(dian)壓(ya)與電(dian)源電(dian)壓(ya)不符（例如現(xian)有接觸器線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)工作電(dian)壓(ya)為(wei)380伏(fu),而電(dian)源電(dian)壓(ya)為(wei)220伏(fu)）,這(zhe)(zhe)時就需要(yao)重繞線(xian)(xian)圈(quan)(quan)(quan),如果(guo)已知現(xian)有線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)參(can)(can)數,我們可以在(zai)這(zhe)(zhe)些參(can)(can)數的(de)(de)(de)(de)基礎上(shang)進行換(huan)算以求得所要(yao)重繞線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)參(can)(can)數,在(zai)進行換(huan)算時的(de)(de)(de)(de)原則是(shi): 1.保證電(dian)磁(ci)系統的(de)(de)(de)(de)吸(xi)力不變(bian),對于直(zhi)流電(dian)壓(ya)線(xian)(xian)圈(quan)(quan)(quan)來(lai)說,就是(shi)要(yao)保證線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)磁(ci)勢不變(bian),對于交流電(dian)壓(ya)線(xian)(xian)圈(quan)(quan)(quan)來(lai)說,就是(shi)要(yao)保證鐵心中的(de)(de)(de)(de)磁(ci)通不變(bian)。 2.保證線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)溫升不變(bian),也就是(shi)說線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)發熱功率和(he)線(xian)(xian)圈(quan)(quan)(quan)外形(xing)尺寸。
