Description
Technical field
The present invention relates to a kind of fuse switch, particularly relate to contact connecting terminal block under a kind of distribution stand fuse switch.
Background technology
Fuse switch, because of features such as economy, flexibility and accommodative ability of environment are strong, is widely used in pole type transformer stand, cable stand primary side, as overcurrent protective switch equipment.But fuse switch is in the process of application, also show some drawbacks because of its lower contact point structure problem, concrete condition is as follows:
1, under drop type contact copper aluminium contact because of the reasons such as wind pendulum stressed at Cu and Al combination place easy fracture, thus initiating failure.
2, drop type lower terminal contact and the horizontal female copper aluminium node real contact area deficiency that goes between of transformer, easily cause the overheated scaling loss of contact.
3, the horizontal bus of transformer is generally 35mm2JKLYJ type insulated conductor, cannot install earth connection, under fuse switch switch contact and upper contact distance be 0.3 m less than 0.7m, do not meet like this installing earth connection trouble free service requirement.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide contact connecting terminal block under a kind of distribution stand fuse switch, solving fuse switch in the process of application, there is the problem of potential safety hazard in lower contact connected mode.
Technical scheme of the present invention is as follows:
Terminal board body comprises linkage section, horizontal segment and latter end; Linkage section and being all obliquely installed between latter end and horizontal segment; Linkage section and latter end are equipped with bolt hole, connecting bolt on bolt hole; Horizontal segment is provided with connecting hole, connecting bolt formula ground loop on connecting hole.
Described body overall length 400 mm, wide 30 mm, thick 5 mm; Connect segment length 150mm, horizontal segment length 200mm, the long 50mm of latter end.
Angle of inclination between described linkage section and horizontal segment is 105 °-115 °.
Angle of inclination between described horizontal segment and latter end is 105 °-115 °.
Described bolt hole and the diameter of connecting hole are 6mm.
Described bolt hole is apart from edge 30mm, and connecting hole is apart from latter end 20mm.
Described bolt and bolt type ground loop are provided with neonychium.
Described linkage section is provided with polishing layer, and polishing layer outer surface scribbles conductive layer.
Advantageous effect of the present invention is as follows:
1, the distance of the horizontal bus lead-in wire of transformer is shortened, the transverse direction being adjusted to shortening by original vertical, lateral anglesization lead-in wire goes between, decrease the mechanically stressed point connecting contact place and cause because of reasons such as wind pendulum, simultaneously because lower connection point terminal row is directly connected and fixed with drop type insulator, enhance bonding strength, the mechanical bearing capacity of contact junction under raising drop type.
2, increase the physical contact area of junction, strengthen the electric current handling capacity of junction.Because under drop type, connection point terminal row adopts smooth connection with the horizontal bus leading line terminals of transformer, make the planar connection portions around bus leading line end sub-aperture, equal can coming with drop type lower terminal physically effectively contacts, and be connected on polishing layer with the basis of conductive layer, add actual contact area, enhance through-current capability, decrease the possibility of contact scaling loss.
3, after drop type lower terminal row angular extends, product itself comprises electricity testing grounding ring, solve become the horizontal bus operation of platform and pole type transformer operation high-pressure side cannot the problem of hanging earthing conductor, really meet the related request becoming platform standardized work, be more convenient for becoming platform operating personnel and effectively take technical safety measures in this operation, thus ensure personal safety.

Embodiment
embodiment
As shown in Figure 1-2, terminal board body comprises linkage section 1, horizontal segment 2 and latter end 3, body overall length 400 mm, wide 30 mm, thick 5 mm; Connect segment length 150mm, horizontal segment length 200mm, the long 50mm of latter end; Linkage section and being all obliquely installed between latter end and horizontal segment, the angle of inclination a between linkage section and horizontal segment is 105 °-115 °, and the angle of inclination b between horizontal segment and latter end is 105 °-115 °; Linkage section and latter end are equipped with the bolt hole 4 that diameter is 6mm, are convenient to insulated conductor and adopt terminal to be effectively connected with drop type terminal board, bolt hole distance edge 30mm, connecting bolt on bolt hole, bolt is provided with neonychium; Horizontal segment is provided with diameter 6mm connecting hole, connecting hole distance latter end 20mm, connecting bolt formula ground loop 5 on connecting hole, and bolt type ground loop is provided with neonychium; Described linkage section is provided with polishing layer, and polishing layer outer surface scribbles conductive layer, increases actual connection contact-making surface, prevents tie point loose contact.By effectively regulating the angle of bend of terminal board, thus ensure that terminal board ground loop and the drop type upper contact electro-mechanical part distance of positions keep more than 0.7m from L.Drop type terminal board all carries out insulation processing except within the scope of the 50mm of two ends.The present invention is by theory calculate and experiment, and after angular extends drop type lower node, the mechanical bearing capacity of drop type meets the requirements, and current capacity significantly improves, and security context obviously improves, and has application and popularization value more widely.
