箱式變壓器又叫箱式變電站，馬路邊，小區里都會有。如果在馬路上，路過一下就算了，但是假如買了個房子，旁邊卻有個箱式變壓器，那么心里肯定納悶了，聽說電氣產品都有電磁輻射，那么這箱式變壓器這么大個頭，它產生的電磁輻射對人體有害嗎？

           箱(xiang)式變(bian)(bian)壓器廠(chang)家(jia)(jia)提醒大(da)家(jia)(jia)，其(qi)實(shi)，不(bu)(bu)用擔心。家(jia)(jia)對(dui)箱(xiang)式變(bian)(bian)電(dian)(dian)(dian)站(zhan)等(deng)高(gao)低壓電(dian)(dian)(dian)氣成套產品的安裝都有規定，箱(xiang)式變(bian)(bian)壓器安裝需要(yao)經過家(jia)(jia)部門嚴(yan)格的“電(dian)(dian)(dian)磁(ci)環評”后才能上馬(ma)，實(shi)際上從目前(qian)已經建成的箱(xiang)變(bian)(bian)等(deng)電(dian)(dian)(dian)力設施(shi)的電(dian)(dian)(dian)磁(ci)測量數據(ju)來(lai)看，其(qi)電(dian)(dian)(dian)磁(ci)輻射值均低于家(jia)(jia)的限(xian)值標準(zhun)。由于居民對(dui)電(dian)(dian)(dian)磁(ci)輻射知識的缺乏，往(wang)往(wang)易產生誤解，從而(er)導致(zhi)許多電(dian)(dian)(dian)力設施(shi)無法如(ru)期(qi)開(kai)工(gong)，如(ru)果這些(xie)計(ji)劃建設的電(dian)(dian)(dian)力設施(shi)再(zai)不(bu)(bu)動工(gong)，目前(qian)電(dian)(dian)(dian)網(wang)的輸電(dian)(dian)(dian)瓶(ping)頸問題將(jiang)更為嚴(yan)重，將(jiang)會(hui)出現有電(dian)(dian)(dian)用不(bu)(bu)上的狀況。

        另外，電磁(ci)輻射不(bu)等(deng)于電磁(ci)污染，只有(you)科學理清概念才能消除不(bu)必要的(de)恐慌(huang)。我(wo)們(men)人(ren)類本身就處在(zai)各(ge)種(zhong)電(dian)(dian)(dian)(dian)(dian)磁(ci)輻(fu)(fu)(fu)射(she)(she)(she)的(de)(de)(de)(de)(de)(de)(de)包圍(wei)之中，天(tian)然磁(ci)場、太陽光等(deng)都會(hui)(hui)(hui)發(fa)(fa)出強度不(bu)同的(de)(de)(de)(de)(de)(de)(de)輻(fu)(fu)(fu)射(she)(she)(she)，不(bu)過(guo)(guo)(guo)只(zhi)(zhi)有當輻(fu)(fu)(fu)射(she)(she)(she)強度超過(guo)(guo)(guo)一定數值（安全值）時才(cai)會(hui)(hui)(hui)對(dui)人(ren)體產生危害，也(ye)就是(shi)(shi)(shi)我(wo)們(men)通常所(suo)說的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)污(wu)(wu)染(ran)。影響人(ren)類生活環境的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)污(wu)(wu)染(ran)主要(yao)來自(zi)(zi)于天(tian)然的(de)(de)(de)(de)(de)(de)(de)和(he)人(ren)為(wei)的(de)(de)(de)(de)(de)(de)(de)兩(liang)大電(dian)(dian)(dian)(dian)(dian)磁(ci)污(wu)(wu)染(ran)源。天(tian)然的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)污(wu)(wu)染(ran)是(shi)(shi)(shi)由某些自(zi)(zi)然現象(xiang)引起(qi)的(de)(de)(de)(de)(de)(de)(de)。較常見的(de)(de)(de)(de)(de)(de)(de)是(shi)(shi)(shi)雷電(dian)(dian)(dian)(dian)(dian)，除了(le)可能對(dui)電(dian)(dian)(dian)(dian)(dian)氣(qi)設備、飛機、建筑(zhu)物(wu)等(deng)直接造成危害外，還會(hui)(hui)(hui)對(dui)從幾千(qian)赫茲(zi)（KHZ）到(dao)幾百兆赫茲(zi)（MHZ）以(yi)上的(de)(de)(de)(de)(de)(de)(de)極寬頻率范圍(wei)內(nei)的(de)(de)(de)(de)(de)(de)(de)廣大地區產生嚴重的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)干(gan)(gan)擾(rao)(rao)(rao)。火山(shan)噴發(fa)(fa)、地震和(he)太陽黑(hei)子(zi)(zi)活動(dong)引起(qi)的(de)(de)(de)(de)(de)(de)(de)磁(ci)暴等(deng)現象(xiang)也(ye)會(hui)(hui)(hui)產生電(dian)(dian)(dian)(dian)(dian)磁(ci)干(gan)(gan)擾(rao)(rao)(rao)，天(tian)然的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)污(wu)(wu)染(ran)對(dui)短波(bo)通信(xin)的(de)(de)(de)(de)(de)(de)(de)干(gan)(gan)擾(rao)(rao)(rao)尤為(wei)嚴重。人(ren)為(wei)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)輻(fu)(fu)(fu)射(she)(she)(she)為(wei)分兩(liang)類：一類是(shi)(shi)(shi)X射(she)(she)(she)線等(deng)電(dian)(dian)(dian)(dian)(dian)磁(ci)的(de)(de)(de)(de)(de)(de)(de)輻(fu)(fu)(fu)射(she)(she)(she)，它(ta)們(men)能使被激發(fa)(fa)物(wu)質產生自(zi)(zi)由電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)，使原子(zi)(zi)成為(wei)帶(dai)電(dian)(dian)(dian)(dian)(dian)離(li)子(zi)(zi)，此種(zhong)輻(fu)(fu)(fu)射(she)(she)(she)稱(cheng)為(wei)電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)(fu)(fu)射(she)(she)(she)，如核設施(shi)、放(fang)射(she)(she)(she)性同位素及各(ge)類放(fang)射(she)(she)(she)性廢物(wu)等(deng)產生的(de)(de)(de)(de)(de)(de)(de)輻(fu)(fu)(fu)射(she)(she)(she)，它(ta)們(men)對(dui)人(ren)體的(de)(de)(de)(de)(de)(de)(de)損(sun)傷是(shi)(shi)(shi)巨大的(de)(de)(de)(de)(de)(de)(de)：另一類是(shi)(shi)(shi)射(she)(she)(she)頻、微(wei)波(bo)等(deng)電(dian)(dian)(dian)(dian)(dian)磁(ci)輻(fu)(fu)(fu)射(she)(she)(she)，它(ta)們(men)不(bu)會(hui)(hui)(hui)使電(dian)(dian)(dian)(dian)(dian)介質的(de)(de)(de)(de)(de)(de)(de)原子(zi)(zi)產生自(zi)(zi)由電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)而電(dian)(dian)(dian)(dian)(dian)離(li)，只(zhi)(zhi)是(shi)(shi)(shi)通過(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)能級的(de)(de)(de)(de)(de)(de)(de)躍(yue)遷而吸收能量(liang)，這種(zhong)輻(fu)(fu)(fu)射(she)(she)(she)稱(cheng)為(wei)非電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)(fu)(fu)射(she)(she)(she)。

          非電離輻射(she)(she)(she)(she)根據其(qi)輻射(she)(she)(she)(she)頻(pin)(pin)率又可分(fen)為微波輻射(she)(she)(she)(she)（300－300000 MHZ）射(she)(she)(she)(she)頻(pin)(pin)輻射(she)(she)(she)(she)（0.1－300 MHZ）和工頻(pin)(pin)輻射(she)(she)(she)(she)（50 HZ或60 HZ）三類。其(qi)中(zhong)無線(xian)(xian)電廣播、電視、無線(xian)(xian)電通信發射(she)(she)(she)(she)臺等各種射(she)(she)(she)(she)頻(pin)(pin)設備的輻射(she)(she)(she)(she)，影響區域(yu)較大，已經成為電磁污(wu)(wu)染環境的主要因(yin)素。東方大華提醒您，箱式變壓器低頻(pin)(pin)噪音污(wu)(wu)染或許(xu)更嚴重。

          高電(dian)(dian)(dian)壓設備不(bu)是(shi)電(dian)(dian)(dian)磁(ci)污染源，居民不(bu)必(bi)擔(dan)心遭受電(dian)(dian)(dian)磁(ci)輻(fu)(fu)射(she)危害。正常運行條件下的(de)(de)(de)高電(dian)(dian)(dian)壓設備，特別(bie)是(shi)輸電(dian)(dian)(dian)線(xian)路附近所(suo)產(chan)生(sheng)的(de)(de)(de)輻(fu)(fu)射(she)主要為50 HZ工(gong)頻(pin)電(dian)(dian)(dian)磁(ci)輻(fu)(fu)射(she)。根據大量的(de)(de)(de)現(xian)場(chang)實測資料表明(ming)，工(gong)頻(pin)電(dian)(dian)(dian)磁(ci)輻(fu)(fu)射(she)的(de)(de)(de)影響范圍十分(fen)有限(xian)，箱(xiang)式變電(dian)(dian)(dian)站(zhan)較(jiao)大的(de)(de)(de)工(gong)頻(pin)電(dian)(dian)(dian)場(chang)強度集中在(zai)進(jin)出線(xian)附近，其它(ta)方位(wei)的(de)(de)(de)工(gong)頻(pin)電(dian)(dian)(dian)場(chang)強度在(zai)2KV/ｍ以下。而(er)對于輸電(dian)(dian)(dian)線(xian)路而(er)言，在(zai)離(li)開邊(bian)導線(xian)10－15ｍ的(de)(de)(de)范圍以外(wai)，工(gong)頻(pin)電(dian)(dian)(dian)場(chang)強度小于居民區工(gong)頻(pin)電(dian)(dian)(dian)場(chang)強度推薦標準4KV/ｍ。

           近幾十年來際大電(dian)(dian)網（CIGRE）發表(biao)的(de)大量科學證據表(biao)明，在(zai)20KV/ｍ以(yi)下的(de)工頻電(dian)(dian)磁(ci)輻(fu)射對(dui)人(ren)體健康(kang)沒(mei)有不良影響，因此對(dui)于居住在(zai)離開箱(xiang)式變電(dian)(dian)站或輸(shu)電(dian)(dian)線(xian)路上述距(ju)離以(yi)外的(de)居民(min)而言，完全沒(mei)有必要(yao)擔心箱(xiang)式變電(dian)(dian)站或輸(shu)電(dian)(dian)線(xian)路電(dian)(dian)磁(ci)輻(fu)射對(dui)人(ren)體的(de)傷(shang)害。

           事實上，一些引起鄰近居民爭議，認為存在電磁污染的新建箱式變電所和輸電線，事后通過部門的實地電磁監測，不僅沒有發現一例超標的情況，而且測量數據往往遠遠低于家推薦的限值標準。所以我們是不必擔心我們生活中常見的箱式變壓器會對我們造成電磁輻射的。
