挑(tiao)選合(he)(he)適的防(fang)雷(lei)(lei)(lei)器(qi)：根據(ju)需要維護的設備和系統，挑(tiao)選合(he)(he)適的防(fang)雷(lei)(lei)(lei)器(qi)類(lei)型(xing)。常見的防(fang)雷(lei)(lei)(lei)器(qi)有電(dian)(dian)源防(fang)雷(lei)(lei)(lei)器(qi)、信(xin)號防(fang)雷(lei)(lei)(lei)器(qi)、天饋防(fang)雷(lei)(lei)(lei)器(qi)等。挑(tiao)選時要注意防(fang)雷(lei)(lei)(lei)器(qi)的工作電(dian)(dian)壓、標(biao)稱放(fang)(fang)電(dian)(dian)電(dian)(dian)流(liu)(liu)、最大放(fang)(fang)電(dian)(dian)電(dian)(dian)流(liu)(liu)等參(can)數是否符(fu)合(he)(he)被維護設備的要求。
正確(que)安(an)(an)(an)裝(zhuang)(zhuang)防(fang)(fang)雷器(qi)：防(fang)(fang)雷器(qi)的(de)安(an)(an)(an)裝(zhuang)(zhuang)位置應(ying)盡(jin)量接(jie)近被維護(hu)設備，減少(shao)連接(jie)電(dian)(dian)(dian)(dian)纜的(de)長度，以降(jiang)低雷電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)通過(guo)電(dian)(dian)(dian)(dian)纜產生的(de)電(dian)(dian)(dian)(dian)壓降(jiang)。對于電(dian)(dian)(dian)(dian)源防(fang)(fang)雷器(qi)，應(ying)安(an)(an)(an)裝(zhuang)(zhuang)在電(dian)(dian)(dian)(dian)源線(xian)路的(de)進線(xian)端；對于信號防(fang)(fang)雷器(qi)，應(ying)安(an)(an)(an)裝(zhuang)(zhuang)在信號線(xian)路的(de)進線(xian)端。
定期檢(jian)查(cha)和維護：防雷器(qi)在長期使用過(guo)程中(zhong)可能會(hui)因多次(ci)雷擊而逐漸損壞(huai)，需要(yao)定期檢(jian)查(cha)其工作狀況。檢(jian)查(cha)時應(ying)注意防雷器(qi)外殼是否完好，接(jie)線是否牢固，有無過(guo)熱、燒(shao)焦等現象。
更換(huan)老(lao)化的防雷(lei)器(qi)：防雷(lei)器(qi)一(yi)般有一(yi)定的使(shi)用(yong)壽命(ming)，使(shi)用(yong)時間過長的防雷(lei)器(qi)其維護性(xing)能可(ke)能會下降，應及時更換(huan)。
