戶外交流高壓跌落式避雷器是將配電型氧化鋅避雷器改裝后巧妙地安裝在跌落熔斷器的跌落式機構上，達到在不斷電的情況下，借助絕緣拉閘操縱桿方便地對避雷器進行檢測、維修與更換，不但保證了線路的暢通，而且大大地減少了電力維護人員的工作強度和時間，適用于10kV及以下輸變電系統(tǒng)中。 

 Outdoor arrester with alternating current high voltage drop skillfully installed the arrester refitted from zinc-Oxide arrester in distribution type on drop-out gear of the drop-out fuse. In the case of continuous power, detection, maintenance and replacement can be carried out conveniently on the arrester with an insulated wind up lever, which can not only keep lines clear but also greatly reduce working strength and time of electricity maintenance personnel. The above mentioned arrester is suitable to power transmission and distribution system with voltage of 10kV and below.

 本產品增加了脫離器，在避雷器出現(xiàn)異常發(fā)生故障時，利用工頻短路電流讓脫離器動作，使脫離器接地端自動脫開，避雷器元件翻落，退出運行防止事故進一步擴大，且易于維護人員及時發(fā)現(xiàn)進行維護和更換。

A disconnector is added to the arrestor, when abnormalities occur and the arrester breaks down, short circuit current of power frequency makes the disconnector move so that earth terminal of the disconnector disengage automatically, components of arresters turn over and are out of operation to prevent the accident from becoming more serious which are easy for maintenance personnel to maintain and replace them timely.

 我公司采用了目前國際最先進的RW12型跌落機構，接觸可靠、分合靈活，并采用復合支柱和不銹鋼蓋的先進配件，具有防污防腐好等優(yōu)點。脫離器有熱熔式和熱爆式兩種，熱熔式脫離器簡單經濟，熱爆式脫離器具有動作速度快，動作電流范圍廣，又能耐受規(guī)定電流沖擊和動作負載的優(yōu)點。

 Our company has adopted the most internationally advanced RW12 drop-out gear with reliable contact which can be opened and shut flexibly. Advanced accessories including compound pillars and stainless steel covers are adopted, which have the advantages of anti-fouling and erosion prevention. There are thermal melt disconnectors and thermal explosive ones. Thermal melt disconnectors are simple and economical, while the thermal explosive ones featured in high action speed, a wide range of operating current, can withstand impact of stipulated current and movement load.
