電子(zi)吊秤怎么防雷(lei)擊呢？打雷(lei)閃電時會導(dao)致大(da)氣電磁場的激烈改變，首要體(ti)現有三種(zhong)物(wu)理進程：

一、電(dian)(dian)磁感(gan)應，即閃(shan)電(dian)(dian)通道(dao)中電(dian)(dian)流隨時(shi)刻發(fa)生改變(bian)，在它周(zhou)圍空間構成改變(bian)的電(dian)(dian)磁場，在通道(dao)附件的導電(dian)(dian)物(wu)體上發(fa)生感(gan)應電(dian)(dian)壓和渦電(dian)(dian)流；

二、靜電感(gan)應，即閃(shan)電導致的(de)地上大(da)氣靜電場改變，使接(jie)閃(shan)物體鄰近(jin)導體發生(sheng)感(gan)應電荷(he)，對地構(gou)成極高的(de)電位差；

三、電(dian)(dian)磁(ci)輻(fu)射，是(shi)由(you)(you)閃(shan)電(dian)(dian)通道中的(de)電(dian)(dian)流極速改變構(gou)成的(de)。由(you)(you)于(yu)電(dian)(dian)子吊秤(cheng)只耐低(di)壓(ya)，因而(er)閃(shan)電(dian)(dian)導致的(de)上(shang)述(shu)三種(zhong)物理進程對其(qi)損壞性，尤(you)其(qi)是(shi)電(dian)(dian)磁(ci)感應。微(wei)電(dian)(dian)子設(she)備越(yue)先進、耗電(dian)(dian)越(yue)小、越(yue)活絡，則損壞性越(yue)大(da)。

因(yin)而，電子(zi)吊秤(cheng)避免雷(lei)擊要做(zuo)好以下作業：

一(yi)、在(zai)秤(cheng)(cheng)體(ti)鄰近(jin)上空要設置(zhi)避雷(lei)針(zhen)(zhen)，以尖(jian)端放電(dian)(dian)效(xiao)應中(zhong)和云團(tuan)中(zhong)的(de)電(dian)(dian)荷，使電(dian)(dian)子吊秤(cheng)(cheng)不致因(yin)雷(lei)擊而(er)損壞。避雷(lei)針(zhen)(zhen)的(de)高度(du)可依據(ju)電(dian)(dian)子吊秤(cheng)(cheng)長(chang)度(du)而(er)定(ding)，避雷(lei)針(zhen)(zhen)維護(hu)半(ban)徑等(deng)于其高度(du)的(de)一(yi)個圓(yuan)形區域。

二、整個(ge)秤臺要接(jie)(jie)地(di)(di)，用一根或數根接(jie)(jie)地(di)(di)電(dian)纜將秤體與接(jie)(jie)地(di)(di)樁(zhuang)相連，接(jie)(jie)地(di)(di)樁(zhuang)要打在電(dian)位穩定的零區，且接(jie)(jie)地(di)(di)電(dian)阻小(xiao)于4。秤臺與接(jie)(jie)地(di)(di)樁(zhuang)之(zhi)間有了(le)寬闊的大(da)電(dian)流(liu)回流(liu)通道，則(ze)當靜電(dian)感(gan)應時(shi)，能(neng)夠從大(da)地(di)(di)彌補電(dian)子(zi)使其(qi)間和，在設(she)備發生高電(dian)位后能(neng)疾(ji)速分散而(er)不致損壞電(dian)子(zi)吊秤。

三、每個傳(chuan)感(gan)(gan)器(qi)要(yao)(yao)有維護接(jie)地(di)(di)(di)。因而每個傳(chuan)感(gan)(gan)器(qi)方位要(yao)(yao)設(she)置(zhi)一個接(jie)地(di)(di)(di)線，傳(chuan)感(gan)(gan)器(qi)與(yu)“地(di)(di)(di)”之間設(she)置(zhi)接(jie)地(di)(di)(di)樁，接(jie)地(di)(di)(di)線與(yu)接(jie)地(di)(di)(di)樁進(jin)行牢靠銜(xian)接(jie)或將(jiang)接(jie)地(di)(di)(di)線與(yu)就近地(di)(di)(di)腳螺栓銜(xian)接(jie)。但地(di)(di)(di)腳螺栓有必要(yao)(yao)與(yu)根底內鋼筋接(jie)地(di)(di)(di)網相連(lian)。

四、穿(chuan)信號電纜的(de)金(jin)屬穿(chuan)線管也有必(bi)要與(yu)接地網(wang)相連。

五、稱(cheng)重傳感(gan)器信號電(dian)(dian)(dian)纜(lan)的(de)屏蔽層要接地(di)。電(dian)(dian)(dian)子吊秤由(you)市電(dian)(dian)(dian)電(dian)(dian)(dian)網供電(dian)(dian)(dian)時，從配電(dian)(dian)(dian)室(shi)到設備(bei)地(di)有(you)根(gen)長一(yi)段空(kong)間(jian)間(jian)隔(ge)，秤臺到秤房也有(you)一(yi)段較氏間(jian)隔(ge)的(de)信號電(dian)(dian)(dian)纜(lan)，不難(nan)設想，雷擊(ji)經過電(dian)(dian)(dian)磁(ci)(ci)感(gan)應路徑，在引線(xian)上引人高(gao)電(dian)(dian)(dian)位，就有(you)能夠(gou)形(xing)成稱(cheng)重外表的(de)損壞(huai)(huai)，因而，稱(cheng)重傳感(gan)器的(de)信號線(xian)和鼓勵稱(cheng)重傳感(gan)器的(de)電(dian)(dian)(dian)流電(dian)(dian)(dian)源線(xian)選用將屏蔽層接地(di)的(de)電(dian)(dian)(dian)纜(lan)銜(xian)接，以消除電(dian)(dian)(dian)磁(ci)(ci)感(gan)應雷擊(ji)損壞(huai)(huai)或導致燃爆的(de)能夠(gou)。

稱重傳感器

信號電纜的屏蔽(bi)層能夠與稱(cheng)重(zhong)傳感器的接(jie)地線(xian)相(xiang)連，也能夠與稱(cheng)重(zhong)顯現(xian)器的接(jie)地樁相(xiang)連；可依現(xian)場狀況斷(duan)定(ding)，但不答應雙點別離同兩個(ge)接(jie)地樁人地。

六、稱重(zhong)顯現外(wai)表外(wai)殼(ke)要接地(di)。因而。地(di)秤房內(nei)設(she)接地(di)樁(zhuang)，且與秤的根底內(nei)鋼筋網(wang)（接地(di)）相連，當選用塑料外(wai)殼(ke)時(shi)，應(ying)在外(wai)殼(ke)內(nei)外(wai)表噴涂一層(ceng)金屬(shu)膜再接地(di)。

七(qi)、接(jie)線(xian)盒(he)要接(jie)地。接(jie)線(xian)盒(he)要設置接(jie)地線(xian)與秤體相連。

八(ba)、電源要(yao)有接地(di)，一起(qi)要(yao)配防(fang)浪涌維(wei)護器。
