Abstract
The utility model relates to a high-voltage cable branch box, which comprises a box body, a bus-bar, cable joints, a cable inlet bobbin and a cable outlet bobbin. The bus-bar, the cable joints, the cable inlet bobbin and the cable outlet bobbin are all arranged in the box body. The high-voltage cable branch box is characterized in that both the cable inlet bobbin and the cable outlet bobbin are internally provided with a cable clamping unit respectively. One ends of cables are connected with the cable joints, while the other ends of the cables are supported by the cable clamping units after passing through the cable clamping units. Due to the adoption of the high-voltage cable branch box, the end portions of cables, which are connected with the cable joints, bear a smaller pulling force respectively. Therefore, the connection parts of cables are prevented from breaking.
Description
Technical field
The utility model relates to a kind of power supplying and distributing equipment that is applied to electric power system, is specifically related to a kind of high voltage cable branch box.
Background technology
Existing high voltage cable branch box is generally a stainless steel rectangular box, and parts such as bus row and cable joint are set in the casing.There is following problem in existing high voltage cable branch box: the one, consider easily for cabling, terminal block district and cable joint place in the casing arbitrarily, because three-core cable is connected on the electric cable accessories, play tap, branch, relaying or transformation after the energising, cable line and vigour part arbitrary placement, can produce mutual interference, when plug connects on the cable branch box butt joint sleeve pipe electric cable accessories take place easily and connect fracture, have potential safety hazard.Simultaneously, because the ring network power supply district is in electriferous state all the time, in case can the generation accident during misoperation.The 2nd, high voltage cable branch box is divided into separate several service areas, respectively in order to arrange different circuits and components and parts, causes in each service area of high voltage cable branch box the space narrow and small like this in each service area, and inner ventilation is bad.Owing to will guarantee alternate safe distance requirement, more make the high voltage cable branch box overall volume huge, floor space is also big, and manufacturing expense also increases thereupon.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model is to provide a kind of cable branch box, and the utility model can make the suffered pulling force in end of cable stube cable joint reduce, and can avoid the junction to rupture.
The technical scheme that realizes the utility model purpose is as follows:
High voltage cable branch box, comprise casing, and the bus that is arranged in the casing is arranged and cable joint, also be provided with long cable section of ingoing line tube and cable outlet tube in the described casing, in long cable section of ingoing line tube and cable outlet tube, be equipped with cable clamping device, one end of cable is connected with cable joint, and the other end of cable is supported by clamping device after passing clamping device.
Adopted such scheme, by clamping device cable has been supported, not only be conducive to the arrangement to cable, the layout that makes cable is reasonable standard more.In addition, by the clamping supporting role of clamping device to cable, the suffered pulling force in end of cable stube cable joint is reduced, can avoid the junction to rupture, guarantee the reliability that cable is connected with cable joint.
Further, described clamping device comprises supporting bracket, and supporting bracket is provided with through hole, is provided with the tensioner cover in the through hole.Cable by the tensioner cover with its parcel after, support, this structure to cable fixedly the time comparatively convenient, simple.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of clamping device in the utility model;
1 is casing, and 2 are bus row, and 3 is cable joint, and 4 is the long cable section of ingoing line tube, and 5 is the cable outlet tube, and 6 is clamping device, and 7 is cable, and 8 is supporting bracket, and 9 is the tensioner cover.
Embodiment
See figures.1.and.2, high voltage cable branch box of the present utility model comprises casing 1, and is arranged on bus row 2 and cable joint 3 in the casing 1, also is provided with long cable section of ingoing line tube 4 and cable outlet tube 5 in the described casing 1.Be equipped with cable clamping device 6 in long cable section of ingoing line tube 4 and cable outlet tube 5, an end of cable 7 is connected with cable joint 3, and the other end of cable 7 passes clamping device 6 backs and supported by clamping device.Described clamping device comprises supporting bracket 8, and supporting bracket is provided with through hole, is provided with tensioner cover 9 in the through hole.
