HPRWG1-12F

Drop-out osigurač i pull the load drop-out fuse is is vanjski visokonapon zaštita of električni. It is installed in high-voltage side of the distribution transformer or the Support Link of the distribution line as Transformers and lines short circuit, overload protection, and open, co-load struja. Drop-out fuse is made by the the insulating bracket and fuse tubes, static contact is installed at both ends of the insulation bracket, Moving contact installed on both ends of fuse tube, Fuse tube is composed by inner arc tube and outer phenolic paper tube or epoxy glass cloth tube. Pull load drop-out fuse can enhance flexibility auxiliar contacts and arc chute for open, co-load current.

When drop-out fuse in the normal operation, the fuse tube with fuse tension to form the closed position. When the system fails, the fault current blown fuse quickly, And form of arc, arc tube by the electric arc burning, Decompose large amounts of gas, formed a high pressure in the tube, and formed vertical wind along the pipeline, The arc was quickly stretch and elongated. After fuse blows, the moving contact lose tension and turned out, locking mechanism, release fuse tube, fuse tube drop, formed breaking Position. When pull the load, use insulating rod to pull the moving contact. At this point, the moving and the static contact is still contact. Continued pull the contact with the insulating rod, the auxiliary contacts are separated. the arc appear between the auxiliary contacts, and was stretch in the hood slit, the arc cover has gas, when the current is 0, the arc goes out.

Ovo proizvod je korišteno 10 ~ 35KV distribucija linije grananje linije linije i distributori transformatori primarni strana, For preopterećenje i kratki krug zaštita Separacija i Kombinacija the ocijenjeno opterećenje struja.
