户外交流高压跌落式避雷器

户外交流高压跌落式避雷器是将配电型氧化锌避雷器改装后巧妙地安装在跌落熔断器的跌落式机构上，达到在不断电的情况下，借助绝缘拉闸操纵杆方便地对避雷器进行检测、维修与更换，不但保证了线路的畅通，而且大大地减少了电力维护人员的工作强度和时间，适用于10kV及以下输变电系统中。 

 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.

 本产品增加了脱离器，在避雷器出现异常发生故障时，利用工频短路电流让脱离器动作，使脱离器接地端自动脱开，避雷器元件翻落，退出运行防止事故进一步扩大，且易于维护人员及时发现进行维护和更换。

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.

 我公司采用了目前国际最先进的RW12型跌落机构，接触可靠、分合灵活，并采用复合支柱和不锈钢盖的先进配件，具有防污防腐好等优点。脱离器有热熔式和热爆式两种，热熔式脱离器简单经济，热爆式脱离器具有动作速度快，动作电流范围广，又能耐受规定电流冲击和动作负载的优点。

 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.
