The most frequently used in the market straight-through/insulation transition joint has three kinds of forms---rubber prefabricated component joint, silicon rubber cold-contraction type joint and predilation formula joint.No matter be rubber prefabricated component joint, silicon rubber cold-contraction type joint, or predilation form joint, all be difficult to satisfy the insulation external diameter technically and differ bigger (such as 500mm
2With 800mm
2) cable butting, because differing the air gap of bigger generation, the cable insulation external diameter can cause partial discharge quantity bigger than normal, even the possibility that causes joint to be climbed wearing.And their mounting means all is earlier adapter body to be enclosed within on the cable, and crimping connects gold utensil then; therefore cable handling length is longer; adapter body itself does not possess water resistance yet in addition, solve waterproof and dampproof problem by means of the encapsulating containment vessel, and very inconvenience is installed.Offhand ready and when needing wherein ready cable operation when a branch line of butt joint cable, three kinds of traditional joints all can't be realized on function.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can realize different cross section cable butting, offhand when ready at a branch line of butt joint cable, and the high voltage power cable that can realize the operation earlier of ready cable, need not fill any insulation pouring agent, waterproof, protection against the tide, anti-mechanical damage is with plug-in reducing cable butting joint.
In order to address the above problem, the high voltage power cable that the utility model provides plug-in reducing cable butting joint, adapter body is by being the main insulation and the connecting cylinder of base material with the High Performance Insulation resin, screen, containment vessel, the integrated poured moulding of metal insert, described containment vessel outer surface is sprayed with the insulation sheath, first stress cone with cable insulation outside dimension coupling is installed on the cable, the core of described cable is provided with occluder and wedge shape tube, the holder of first spring awl holds out against described first stress cone on the inner conical surface of described adapter body one end, occluder and wedge shape tube are inserted in the described connecting cylinder, be provided with the stop cover between described stress cone and described connecting cylinder, the tail pipe of band earth terminal passes through metal insert, the tail pipe sealing ring is installed on the described adapter body; The holder of second spring awl holds out against second stress cone, plug on the inner conical surface of the described adapter body other end, is provided with on the end face of described adapter body and described second spring awl holder corresponding shell.
Adopt the high voltage power cable plug-in reducing cable butting joint of technique scheme, be mainly used in the connection of high voltage power cable, the Stress Control unit that originally is overall shaped in the adapter body is independent, realized the butt joint of the irrealizable reducing cable of conventional joint, the mold pressing connected mode is exempted from being connected to of wedge shape tube, occluder and cable core; Wedge shape tube, occluder are connected with the plug-in that is connected between the adapter body.Adopted plug-in structure very easily is installed, reduced difficulty of construction, integral body is dry construction, need not fill any insulation pouring agent, and the fault of having stopped to cause because of leakage produces.The intact stress cone that puts of cable handling, then after putting stop cover, occluder on the cable core, the wedge shape tube is installed on the described occluder with specific purpose tool by technological requirement, then cable is inserted in the adapter body, described wedge shape tube is finished be inserted in the interior connecting cylinder of described adapter body, then the holder of spring awl is installed on the described adapter body, to install by technological requirement with the tail pipe of earth terminal again, carry out corresponding seal operation, and with each grounded part reliable ground.
In sum, the utility model be a kind of volume little, in light weight, easy for installation, can realize different cross section cable butting, offhand when ready at a branch line of butt joint cable, the high voltage power cable that can realize the operation earlier of ready cable, need not fill any insulation pouring agent, waterproof, protection against the tide, anti-mechanical damage is with plug-in reducing cable butting joint.
