ZGR Series, RW Series
Drop-out Type High-voltage Fuse Protector
ZGR Series, RW Series are outdoor high-voltage fuses, usually installed on the high-voltage side of distribution transformers or distribution branch lines, for short-circuit and overload protection of high-voltage transformers and lines. When a circuit fault occurs, the fuse blows quickly, creating an arc. The arc suppression tube is heated by the electric arc, and a large amount of gas is generated. At this time, a huge pressure is generated in the tube, and it is blown vertically along the pipeline stroke, so that the arc is quickly elongated and extinguished. After the fuse is blown, the lower moving contact loses tension and turns down, and the locking mechanism releases the fuse tube, causing the fuse tube to drop, forming an obvious breaking gap.
