Abstract
The utility model discloses a cable branching box for urban power grid cabling reconstruction, which serves to tap, branch, relay or convert, and an H busbar (2), an H busbar (3) and an H busbar (4) are mounted obliquely and sequentially from the bottom up on the inner side of the high-voltage cable branching box casing (1), and corresponding cable accessories are mounted at the 12 ports of the H busbar (2), the H busbar (3) and the H busbar (4).
Description
Affiliated technical field
The utility model relates to a kind of high voltage cable branch box of multiple current branches.
Background technology
At present, the cable branch box that is used for city net cable transformation, employing is installed three butt joint sleeve pipes side by side in cable branch tank shell inboard, but adopt pluggable mode that electric cable accessories is installed on the port of butt joint sleeve pipe two ends, three-core cable is connected on the electric cable accessories, plays tap, branch, relaying or transformation after the energising.Under the situation of a current branch number of pre-increase, to on three each ports of butt joint sleeve pipe one end front connector be installed respectively, to promptly increase by one road electric current after the three-core cable connection energising, again the back joint is plugged respectively and is connected in the front connector, another root three-core cable is connected back joint energising promptly increases by one the tunnel again on original current branch number.Because cable branch box adopts on the butt joint sleeve pipe and can plug when connecting, increase the plug installation that the current branch number must carry out the respective cable annex in advance, largely increase the space of cable branch tank shell, manufacturing expense also increases thereupon.Plug at the multiple-limb number connects, because the electric cable accessories own wt electric cable accessories easily takes place connects fracture, has potential safety hazard.
Summary of the invention
For effectively saving the space of cable branch box, reduce manufacturing expense, prevent that multiple-limb electric current plug connection from security incident taking place, the utility model provides a kind of high voltage cable branch box.
Technical scheme
A kind of high voltage cable branch box adopts in high voltage cable branch box housing (1) inboard from top to bottom to tilt H type busbar (2), H type busbar (3), H type busbar (4) are installed successively, electric cable accessories is installed in successively on 12 ports of H type busbar (2), H type busbar (3), H type busbar (4).H type busbar (2) the electric cable accessories unanimity that two ends connected; Two ports of H type busbar (2) one ends are installed front connector (5), back joint (6) from the inside to surface successively, front connector (7), back joint (8).H type busbar (3) the electric cable accessories unanimity that two ends connected; Two ports of H type busbar (3) one ends are installed front connector (9), back joint (10) from the inside to surface successively, front connector (11), back joint (12).H type busbar (4) the electric cable accessories unanimity that two ends connected; Two ports of H type busbar (4) one ends are installed front connector (13), back joint (14) from the inside to surface successively, front connector (15), back joint (16).
Because H type busbar (2), H type busbar (3), each end of H type busbar (4) have two ports to be used for the stube cable annex respectively.The promptly pre-two-way current branch number that increases, only need to connect front connector respectively at H type busbar (2), H type busbar (3), two ports of H type busbar (4) one ends, to get final product after two three-core cables connection front connector energisings, under the constant situation of used electric cable accessories quantity, increase by one times of space of two-way current branch number saving than adopting the butt joint sleeve pipe to connect.When the plug of multiple-limb electric current connects, to compare the butt joint sleeve pipe and adopt two terminations to come the balanced weight of attachment, a kind of high voltage cable branch box adopts four terminations to come the compensating cable weight of attachment, effectively prevents the generation of multiple-limb plug attachment security hidden danger.
