避雷器的工作原理

2020-10-08

避(bi)雷器是連接在導線和地之間的(de)一種防止雷擊的(de)設(she)備，通常與(yu)被保護(hu)設(she)備并(bing)聯。

避(bi)雷器是如何避雷的？詳解氧化鋅避雷器的工作原理和使用

避(bi)雷器可以有效的保(bao)(bao)護(hu)(hu)(hu)(hu)電(dian)(dian)(dian)力設(she)(she)(she)備，一旦出現不正常電(dian)(dian)(dian)壓(ya)，避(bi)雷器產(chan)生(sheng)作(zuo)(zuo)(zuo)用，起到(dao)保(bao)(bao)護(hu)(hu)(hu)(hu)作(zuo)(zuo)(zuo)用。當(dang)被保(bao)(bao)護(hu)(hu)(hu)(hu)設(she)(she)(she)備在正常工作(zuo)(zuo)(zuo)電(dian)(dian)(dian)壓(ya)下運行時，避(bi)雷器不會產(chan)生(sheng)作(zuo)(zuo)(zuo)用，對(dui)地(di)(di)面來說視為斷路。一旦出現高(gao)電(dian)(dian)(dian)壓(ya)，且危及被保(bao)(bao)護(hu)(hu)(hu)(hu)設(she)(she)(she)備絕(jue)(jue)緣(yuan)時，避(bi)雷器立即(ji)動作(zuo)(zuo)(zuo)，將高(gao)電(dian)(dian)(dian)壓(ya)沖擊(ji)電(dian)(dian)(dian)流導向大(da)地(di)(di)，從而(er)限制電(dian)(dian)(dian)壓(ya)幅(fu)(fu)值，保(bao)(bao)護(hu)(hu)(hu)(hu)電(dian)(dian)(dian)氣設(she)(she)(she)備絕(jue)(jue)緣(yuan)。當(dang)過電(dian)(dian)(dian)壓(ya)消失后，避(bi)雷器迅速恢復(fu)原狀，使系統能夠正常供(gong)電(dian)(dian)(dian)。避(bi)雷器的主(zhu)要作(zuo)(zuo)(zuo)用是通過并(bing)聯放電(dian)(dian)(dian)間隙(xi)或非(fei)線性電(dian)(dian)(dian)阻的作(zuo)(zuo)(zuo)用，對(dui)入侵(qin)流動波進行削幅(fu)(fu)，降低被保(bao)(bao)護(hu)(hu)(hu)(hu)設(she)(she)(she)備所受過電(dian)(dian)(dian)壓(ya)值，從而(er)達到(dao)保(bao)(bao)護(hu)(hu)(hu)(hu)電(dian)(dian)(dian)力設(she)(she)(she)備的作(zuo)(zuo)(zuo)用。避(bi)雷器不僅可用來防護(hu)(hu)(hu)(hu)大(da)氣高(gao)電(dian)(dian)(dian)壓(ya)，也可用來防護(hu)(hu)(hu)(hu)操作(zuo)(zuo)(zuo)高(gao)電(dian)(dian)(dian)壓(ya)。
