Outdoor arrester with alternating current high voltage drop skillfully installed the arrester refitted from zinc-Oxide arrester in distribution type on 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.
A disconnector is added to the arrester, 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.
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 anto-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.
