 跌落式復合外套氧化鋅避雷器 







       可投式、可卸式避雷器是將氧化鋅避雷器改裝后巧妙地安裝在跌落式熔斷器的跌落式機構上,達到在不斷電的情況下,可以借助絕緣拉閘操縱桿方便地對避雷器進(jìn)行檢測、維修與更換,不但保證了線(xiàn)路的暢通,而且大大地減少了電力維護人員的工作強度和時(shí)間,特別適合于
不宜停電的場(chǎng)所如郵電通訊、機場(chǎng)、車(chē)站、醫院、繁華商業(yè)區等。產(chǎn)品其它性能同配電型避雷器。
       跌落式避雷器增加了脫離器,避雷器被雷擊過(guò)電后,如果避雷器外觀(guān)無(wú)損壞時(shí),人工用眼觀(guān)察是較難發(fā)現的,這使尋找故障點(diǎn)進(jìn)行修復很費時(shí),另一方面繼承了可卸式避雷器的特點(diǎn),避雷器過(guò)電故障后,由于仍與電網(wǎng)連接,更換新的避雷器時(shí)要么帶電作業(yè),要么線(xiàn)路拉閘停
電,給修復更換工作造成麻煩,也拖延了電網(wǎng)恢復時(shí)間。
      本跌落式避雷器出現異常發(fā)生故障時(shí),利用工頻短路電流讓脫離器動(dòng)作,使脫離器接地端自動(dòng)脫開(kāi),避雷器元件翻落,退出運行防止事故進(jìn)一步擴大,并易于維護人員及時(shí)發(fā)現進(jìn)行維護和更換。其翻落原理類(lèi)似熔斷器熔絲熔斷熔斷引起熔管翻落。我公司采用了目前國際最先
進(jìn)的熱爆式脫離器,具有動(dòng)作速度快,動(dòng)作電流范圍廣,又能耐受規定電流沖擊和動(dòng)作負載的優(yōu)點(diǎn)。

型號及含義


產(chǎn)品電氣參數表


安裝使用說(shuō)明
       1.安裝使用前請檢查避雷器元件與跌落式機構之間的松緊程度,以保證接觸良好并投卸靈活。
       2.跌落式機構上接線(xiàn)端接高壓線(xiàn),下接線(xiàn)端必須可靠接地,切勿接反。
       3.避雷器在投入運行前和投入運行后的注意事項同普通避雷器。
       4.當避雷器需要檢修或更換時(shí),可在不斷電的情況下,借助絕緣拉閘操縱桿對準避雷器單元上的拉鉤進(jìn)行方便的操作,如同更換跌落式熔管。
