浪涌保(bao)護(hu)(hu)器(qi)，也叫防(fang)(fang)雷(lei)器(qi)，是一種(zhong)為各(ge)種(zhong)電(dian)(dian)子(zi)設(she)備(bei)(bei)、儀器(qi)儀表、通訊線(xian)路(lu)(lu)提供安全防(fang)(fang)護(hu)(hu)的電(dian)(dian)子(zi)裝置。里(li)面(mian)的防(fang)(fang)雷(lei)導熱(re)石(shi)墨(mo)片起到關鍵的防(fang)(fang)護(hu)(hu)作(zuo)用，當電(dian)(dian)氣回路(lu)(lu)或者通信線(xian)路(lu)(lu)中因為外(wai)界的干擾突然產生尖峰電(dian)(dian)流或者電(dian)(dian)壓時，浪涌保(bao)護(hu)(hu)器(qi)能在(zai)極短的時間內(nei)導通分(fen)流，從(cong)而(er)避免浪涌對回路(lu)(lu)中其他設(she)備(bei)(bei)的損(sun)害。下面(mian)青島聚和稀(xi)碳小編(bian)介紹間隙型防(fang)(fang)雷(lei)導熱(re)石(shi)墨(mo)片特性與用途(tu)：

       原(yuan)始(shi)的防(fang)雷(lei)(lei)器(qi)是羊角形間隙(xi)，出(chu)(chu)現(xian)于19世紀末期，用于架(jia)空(kong)輸(shu)電線路，防(fang)止雷(lei)(lei)擊損壞設備(bei)絕緣而造(zao)成停電，故稱“防(fang)雷(lei)(lei)器(qi)”。20世紀20年代(dai)，出(chu)(chu)現(xian)了(le)鋁防(fang)雷(lei)(lei)器(qi)，氧化(hua)膜防(fang)雷(lei)(lei)器(qi)和丸式(shi)防(fang)雷(lei)(lei)器(qi)。30年代(dai)出(chu)(chu)現(xian)了(le)管式(shi)防(fang)雷(lei)(lei)器(qi)。50年代(dai)出(chu)(chu)現(xian)了(le)碳(tan)化(hua)硅防(fang)雷(lei)(lei)器(qi)。70年代(dai)又出(chu)(chu)現(xian)了(le)金(jin)屬氧化(hua)物防(fang)雷(lei)(lei)器(qi)。

       防(fang)雷(lei)器(qi)(qi)石墨(mo)片(pian)是用來生(sheng)產(chan)防(fang)雷(lei)器(qi)(qi)的(de)配件,作為導電(dian)(dian)(dian)(dian)(dian)間隙，雷(lei)擊時，巨大(da)的(de)電(dian)(dian)(dian)(dian)(dian)流通過導線(xian)引向防(fang)雷(lei)器(qi)(qi)，然后石墨(mo)片(pian)承載了大(da)量電(dian)(dian)(dian)(dian)(dian)流，減輕了電(dian)(dian)(dian)(dian)(dian)源的(de)荷載，保護(hu)了電(dian)(dian)(dian)(dian)(dian)源。電(dian)(dian)(dian)(dian)(dian)涌保護(hu)器(qi)(qi)的(de)類型和(he)結(jie)構按不同的(de)用途有所不同，但它至(zhi)少應包含(han)一個非線(xian)性電(dian)(dian)(dian)(dian)(dian)壓(ya)限制元件。用于電(dian)(dian)(dian)(dian)(dian)涌保護(hu)器(qi)(qi)的(de)基本元器(qi)(qi)件有：放電(dian)(dian)(dian)(dian)(dian)間隙、充氣放電(dian)(dian)(dian)(dian)(dian)管(guan)(guan)、壓(ya)敏電(dian)(dian)(dian)(dian)(dian)阻、抑(yi)制二極(ji)管(guan)(guan)和(he)扼流線(xian)圈等。

       石(shi)(shi)墨間(jian)隙(xi)(xi)防(fang)雷(lei)器是(shi)采(cai)用防(fang)雷(lei)間(jian)隙(xi)(xi)導熱(re)石(shi)(shi)墨片作為(wei)放(fang)電(dian)(dian)間(jian)隙(xi)(xi)的防(fang)雷(lei)器，這種避雷(lei)器主要利用的是(shi)多(duo)層間(jian)隙(xi)(xi)連續(xu)放(fang)電(dian)(dian)，每層放(fang)電(dian)(dian)間(jian)隙(xi)(xi)相互(hu)絕緣，這種疊層技術不僅(jin)解決了續(xu)流(liu)(liu)問題而且是(shi)逐層放(fang)電(dian)(dian)，無形中增大了產品自身的通(tong)流(liu)(liu)能力。優點：放(fang)電(dian)(dian)電(dian)(dian)流(liu)(liu)大，測(ce)試(shi)50KA（實際測(ce)量值）漏電(dian)(dian)小，無續(xu)流(liu)(liu)，無電(dian)(dian)弧外瀉，熱(re)穩(wen)定(ding)性(xing)好。缺點：殘(can)壓高，反應(ying)時(shi)間(jian)慢。一體(ti)的專業石(shi)(shi)墨原(yuan)料，石(shi)(shi)墨制品供應(ying)商。品種齊(qi)全，交(jiao)貨及時(shi)，穩(wen)定(ding)性(xing)好，免費拿樣(yang)，按(an)需定(ding)制。
