Again, be provided with two electrode chambers in the described insulating body, described two fixed electrodes are installed in this two electrode chambers respectively.
Have, the interior end of cartridge fuse described in the utility model also is equipped with the compression spring represents pipe with the fusing that can eject expression again; The described insulation lid one distolateral through hole that ejects for fusing expression pipe that has, the fusing expression pipe other end is connected in the lead in the cartridge fuse.
Described insulation lid one side is connected in insulating body one side by a bearing pin.
In addition, described cartridge fuse is an insulated tube.
Described cartridge fuse is an insulated tube, and by inside and outside two-layer the composition, skin is to be made by glass fibre; Internal layer is can produce gas and carry out the arc extinguishing materials with function and make by having.
Described arc-control device is can produce the material that gas carries out arc extinguishing and form by having.
Described insulating body, insulation lid are made by electroceramics or fiberglass (FRP), epoxy resin, silicon rubber synthetic resin.
When the overcurrent that surpasses rated current flows through; the fuse that is provided with in the cartridge fuse is fused, and fusing back lead is because the open power of compression spring makes being forced to property of fuse separately; electric connection between the movable contact edge also is separated, thereby the machine of load side is protected.
The beneficial effects of the utility model:
In the seal cavity of insulating body and the formation of insulating lid body, cartridge fuse is installed, can prevent that cartridge fuse is stolen, fixed electrode, movable contact edge etc. can not be subjected to typhoon, storm, air pollution, the influence of dust etc. and wearing out, thus can be also stable for a long time electric power is provided.
When can carry out overcurrent protection to transformer, because have the switch sections of narrow slit arc-control device, so can under electriferous state, carry out switching manipulation and safe power cut construction with fuse.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model one embodiment.
Embodiment
Referring to Fig. 1, the utility model box-shaped closed belt switch fuse comprises, insulating body 1, and it is a box structure, is provided with two electrode chambers 6,7 in the insulating body; Its back side, outside is provided with installation connector 4,5 and is fixed on the electric pole.
Insulation lid 2, the one side is movably connected on insulating body 1 one sides rotationally by a bearing pin 3, can form confined space with insulating body 1 and cooperate; This insulation lid 2 one distolateral through hole 2b that have; Recess 2a of insulation lid 2 inboard formation with accommodation space;
Two fixed electrodes 8,10 are installed on respectively in the electrode chamber 6,7 of insulating body 1, and electrically connect by splicing ear 9,11 and outside lead; Electrode chamber 6 is positioned at load side, and electrode chamber 7 is positioned at mains side;
Arc-control device 12 covers at respectively outside the fixed electrode 8,10, and it is can produce the material that gas carries out arc extinguishing and form by having;
Cartridge fuse 13 is arranged in the insulation lid 2 recess 2a, establishes fuse 20 and lead 21 in it; These cartridge fuse 13 interior ends also are equipped with compression spring 17 represents to manage 18 with the fusing that can eject expression; Fusing expression pipe 18 1 ends are connected in the lead 21 in the cartridge fuse 2, and fusing expression pipe 18 other ends can eject the distolateral through hole 2b of insulation lid 2 one; Fuse keeps the compression spring to be in confined state by fusing expression pipe 18.(fusing expression pipe 18 is not from the outstanding state of insulation lid 2 rear end through hole 2b).
Two movable contact cuttves 15,16, be individually fixed on the aforementioned cartridge fuse 13, with aforementioned dielectric body 1 in two fixed electrodes, 10,8 corresponding positions on, and form series connection by fuses 20 in the cartridge fuse 13 and lead 21 and electrically connect;
Along with the folding of insulation lid 2, movable contact edge 15,16 can insert or break away from the fixed electrode 10,8 of aforementioned dielectric body 1.
