Utility model content
The purpose of this utility model is exactly to solve the problem, and provides a kind of wiring effective, and improve cable utilance, joint there will not be the 10-35kV cable joint structure of point discharge.
To achieve these goals, the utility model adopts following technical scheme: a kind of 10-35kV cable joint structure, comprise 10-35kV cable waiting and the 2nd 10-35kV cable waiting, described 10-35kV cable waiting has the first conductor, described first conductor outer wrapping first coating layer, described first coating layer has the first internal shield from inside to outside, first insulating barrier and the first outer shielding layer, described 2nd 10-35kV cable waiting has the second conductor, described second conductor outer wrapping second coating layer, described second coating layer has the second internal shield from inside to outside, second insulating barrier and the second outer shielding layer, described first conductor link has the first extension, described second conductor link has the second extension, described first end, extension and the second extension welding edges, to form the rounded connector portions in cross section, repairing coating layer is set outside described connector portions, described repairing coating layer has repairing internal shield from inside to outside, repair insulating barrier and repair outer shielding layer, repair internal shield two ends respectively with the first internal shield, second internal shield connects, the two ends of repairing insulating barrier are connected with the first insulating barrier, the second insulating barrier respectively, the two ends of repairing outer shielding layer are connected with the first outer shielding layer, the second outer shielding layer respectively.
Preferably: the contact-making surface of described repairing coating layer and the first coating layer, and with the contact-making surface of the second coating layer, all in closing in taper.
Preferably: outside described repairing coating layer, reflecting coating band is set.
Compared with prior art, the utility model has following beneficial effect: the utility model can continue to use by after the cable splice that cannot meet length requirement, and wiring effect is better, improves cable utilance, simultaneously in wiring place, there will not be point discharge phenomenon.
Accompanying drawing explanation
Fig. 1 is 10-35kV cable joint structure cross-sectional schematic in embodiment.
Fig. 2 is reflecting coating band schematic diagram in 10-35kV cable joint structure in embodiment.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 and Fig. 2, a kind of 10-35kV cable joint structure, comprise 10-35kV cable waiting 1 and the 2nd 10-35kV cable 2 waiting, described 10-35kV cable 1 waiting has the first conductor 11, described first conductor 11 outer wrapping first coating layer, described first coating layer has the first internal shield 12 from inside to outside, first insulating barrier 13 and the first outer shielding layer 14, described 2nd 10-35kV cable waiting has the second conductor 21, described second conductor 21 outer wrapping second coating layer, described second coating layer has the second internal shield 22 from inside to outside, second insulating barrier 23 and the second outer shielding layer 24, described first conductor 11 link has the first extension 11a, described second conductor 21 link has the second extension 21a, described first 11a end, extension and the second extension 21a welding edges, to form the rounded connector portions in cross section, repairing coating layer is set outside described connector portions, described repairing coating layer has from inside to outside repairs internal shield 31, repair insulating barrier 32 and repair outer shielding layer 33, repair internal shield 31 two ends respectively with the first internal shield 12, second internal shield 22 connects, the two ends of repairing insulating barrier 32 are connected with the first insulating barrier 13, second insulating barrier 23 respectively, the two ends of repairing outer shielding layer 33 are connected with the first outer shielding layer 14, second outer shielding layer 24 respectively.
To repair internal shield (repairing insulating barrier and repair outer shielding layer similar), left and right end in circular repairing internal shield is connected with the first internal shield, the second internal shield respectively, form integral structure, repair the thickness of internal shield and the consistency of thickness of the first internal shield, the thickness repairing internal shield is also consistent with the thickness of the second internal shield.After repairing coating layer is shaping, the cross-sectional area of conductor of connector portions is rounded.
In order to improve intensity and fail safe further, can at the outer sheathed reinforcement structure (not shown) of connector portions, strengthening structure is tubular, strengthen inside diameter slightly larger than the external diameter repairing outer shielding layer, the left end strengthening structure is clamped on 10-35kV cable waiting, and right-hand member is clamped on the 2nd 10-35kV cable waiting.The mode of clamping can with reference to prior art, and strengthening structure object is auxiliary joint portion carrying axial tension.
