For achieving the above object, the utility model provides a kind of direct water cooled fast fuse, comprises several fuse pieces, rebound, insulated tube and conductive plate, and described several fuse pieces all adopt silver strip to make, this fuse piece point is welded on the rebound, is filled with quartz sand between the fuse piece; Described rebound is welded on the conductive plate by ashbury metal, and this conductive plate is that plate body is provided with the copper of water cooling pipeline or aluminium matter water-cooled conductive plate.
Wherein, described conductive plate is the water-cooled conductive plate of setting up outer cooling water pipeline of being located at fuse one end, and this outer cooling water pipeline is connected by a water nozzle and cooling water source.
In the utility model, described conductive plate is the water-cooled conductive plate of setting up interior cooling water pipeline that is assemblied in the fuse two ends, and two interior cooling water pipelines are all connected by a water nozzle and cooling water source.
Direct water cooled fast fuse of the present utility model, it changes to the water-cooled conductive plate of setting up water composite cooling pipe on the plate body with the original copper or aluminium matter conductive plate of fuse, so that the type of cooling of fuse (hot surface is to air radiation by self cooling, be diffused into heat) change into mainly and force cooling by circulating water in the conductive plate water cooling pipeline, fuse is taken away by the cooling water in the heat-conducting plate by the heat that electric current produces, strengthened radiating effect, the single porcelain tube that enlarges a little after this improves can be developed into 6000A-8000A fast acting fuse (replacing original two 3000A or four 1500A parallel-connection structures), having reached increases single fusion tube current capacity, reduce power consumption, reduce the requirements such as switch off time and quickening fusing speed, further improved electrical technology performance and the operating efficiency of fuse.
