Abstract
Disclosed is a current-limiting cable connector for a high voltage electrical connection system of an American box transformer station and an outdoor ringed network, which is characterized in that one end of a fuse (3) is inserted into an elbow-shaped connecting terminal (6) equipped with a copper contact plate (4) and is fixed by a screw (5), the other end of the fuse (3) is screwed into one end of a double-head connecting terminal (2) with threads, the elbow-shaped connecting terminal (6) equipped with the fuse (3) is inserted along the lower end of an elbow-shaped cable connector (7), a plug-pull rod (8) is inserted to be fixed on the elbow-shaped connecting terminal (6) along the upper end of the elbow-shaped cable connector (7), a funnel-shaped rear base (1) is sleeved in along the lower end of the elbow-shaped cable connector (7) until a limit rib of the elbow-shaped cable connector (7) is tightly combined with a limit groove of the funnel-shaped rear base (1), thereby effectively saving space of the high voltage electrical connection system and reducing relative manufacturing cost.
Description
Affiliated technical field
The utility model relates to a kind of electric cable accessories that is used for American case change, outdoor ring main unit high-voltage electrical apparatus connected system.
Background technology
At present, the high-voltage electrical apparatus connected system of American case change, outdoor ring main unit directly adopts the cable joint of no fuse function to connect.For preventing the switch or the fuse of the extra mounting strap fuse function of the excessive burning apparatus of electric current, American case becomes, the space of outdoor ring main unit thereby increase, and manufacturing expense also increases thereupon.
Summary of the invention
American case becomes, the space of outdoor ring main unit high-voltage electrical apparatus connected system in order effectively to save, and reduces manufacturing expense, and the utility model provides the current limliting cable joint.
Technical scheme
When the high-voltage electrical apparatus of American case change, outdoor ring main unit connects, directly adopt the current limliting cable joint to connect.Because the current limliting cable joint adopts fuse (3) one ends are inserted the elbow type binding post (6) that copper contact blade (4) is housed, and fixed with screw (5), fuse (3) other end screws in the threaded end of double end binding post (2); The elbow type binding post (6) that fuse (3) will be housed inserts along elbow type cable joint (7) lower end; Plug bar (8) inserts along elbow type cable joint (7) upper end and is fixed on the elbow type binding post (6); Funnel type back seat (1) is inserted in along elbow type cable joint (7) lower end, combines closely up to the spacing muscle of elbow type cable joint (7) and the stopper slot of funnel type back seat (1).Elbow type cable joint (7) comprises outer conducting layer (12), inner conducting layer (14) and insulating barrier (13); Elbow type cable joint (7) outer surface has a spacing muscle.Funnel type back seat (1) comprises outer conducting layer (11), inner conducting layer (9) and insulating barrier (10); There is a stopper slot funnel type back seat (1) inboard.There are two contact grooves parallel and distance equates with copper contact blade (4) width elbow type binding post (6) groove inboard, is used for fixing copper contact blade (4); Be connected double end binding post (2) one ends with fuse (3) screw thread is arranged.Outer conducting layer (12) composition material is conduction EPDM, and inner conducting layer (14) composition material is conduction EPDM, and insulating barrier (13) composition material is insulation EPDM.Outer conducting layer (11) composition material is conduction EPDM, and inner conducting layer (9) composition material is conduction EPDM, and insulating barrier (10) composition material is insulation EPDM.
Owing to the current limliting cable joint adopts the built-in mode of fuse (3), both reached the effect that American case becomes, in time fuses when outdoor ring main unit high-voltage electrical apparatus connected system electric current is excessive, effectively saved the space of American case change, outdoor ring main unit again.
