Abstract
The utility model discloses a reinforced seal oil-filling type outdoor terminal which comprises a sleeve, a stress cone and a tail pipe, wherein the stress cone and the tail pipe are arranged in the sleeve along the vertical direction; a cable body is penetrated through the stress cone and the tail pipe; a seal component is arranged between the cable body and the tail pipe; and the seal component is tightly attached to the outer surface of the cable body and the inner surface of the tail pipe. The reinforced seal oil-filling type outdoor terminal is simple in structure, convenient to mount and good in seal performance, precludes the potential mounting problem caused by the technical individual difference among construction personnel, prevents the insulating oil in the terminal from leaking along the cable body in an insulating and shielding manner, enables the operation of the cable system to be stable and reliable, and improves the safety.
Description
Technical field
The utility model relates to a kind of high pressure, extra-high-tension cable filling type outdoor terminal, particularly relates to a kind of enhanced leaktightness filling type outdoor terminal.
Background technology
Development along with China's power construction; Electricity needs is constantly soaring; The construction of high pressure and supergrid especially now, the increasing demand of the power cable with cross-linked polyethylene insulation of 66kV and above electric pressure increases, and has also promoted developing rapidly of electric cable accessories simultaneously.The cable outdoor terminal is main electric cable accessories, through it underground cable and the high voltage transmission line positive connection on the high voltage power transmission tower.Present cable termination product comprises dry type silicon rubber outdoor terminal and oil-filled terminal, and widely used is oil-filled terminal.This structure comprises exhausted sleeve pipe, insulating oil, flange, the outlet bar, tail pipe, the earthing device that are connected with cable core.Tail pipe and cable body hold from being connected through self-adhesive tape; Because workmen's individual technological disparity; When holding self-adhesive tape, possibly occur holding bad, perhaps since self-adhesive tape directly contact with insulating oil, make self-adhesive tape swelling in insulating oil; Cause stress relaxation, thereby insulating oil leakage takes place.If the terminal breakdown accident just possibly take place in the long-term seepage of insulating oil.Utilities Electric Co. repeatedly finds cable filling type outdoor terminal insulating oil end seepage situation in the product maintenance process, have no alternative but the maintenance that has a power failure.
The utility model content
Be to provide a kind of enhanced leaktightness filling type outdoor terminal, through increasing seal member, making between cable body and the tail pipe increases secondary seal the order of the utility model, avoids because the stress relaxation of self-adhesive tape causes poor sealing and the seepage insulating oil.
The described a kind of enhanced leaktightness filling type outdoor terminal of the utility model; Comprise sleeve pipe, stress cone, tail pipe; Said stress cone and tail pipe divide upper-lower position to be located in the sleeve pipe; Cable body passes stress cone and tail pipe, between cable body and tail pipe, is provided with seal member, and sealing parts and cable body outer surface and tail pipe inner surface fit tightly.
Described seal member and cable body and tail pipe are interference fit, and seal member adopts silicon rubber to process.
The utility model is through the insulation shielding and the tail pipe interference fit of seal member and cable body, and making between cable body and the tail pipe increases secondary seal, avoids because the stress relaxation of insulation self-adhesive tape causes poor sealing and the seepage insulating oil.
The utlity model has following advantage:
1, product safety is reliable.The seal member that the utility model adopts is that silicon rubber is made; Because the high resiliency of silicon rubber, make cable because variation of temperature is expanded with heat and contract with cold can both be the seal member interference fit, guarantee good sealing property; Make the reliable, stable, safe of cable system.
2, the utility model can use the cable filling type outdoor terminal with different electric pressures, different cross section, highly versatile.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of seal member among Fig. 1.
Embodiment
The structure of the utility model such as Fig. 1 mainly comprise sleeve pipe 1, stress cone 3 and tail pipe 6, in sleeve pipe 1, are full of insulating oil 2.6 fens upper-lower positions of stress cone 3 and tail pipe are located in the sleeve pipe 1; Cable body 4 passes stress cone 3 and tail pipe 6; It is characterized in that between cable body and tail pipe 6, being provided with seal member 5; Sealing parts and cable body 4 outer surfaces and tail pipe 6 inner surfaces fit tightly, and sleeve pipe 1 lower surface is installed on the base 7, and the seal member shape is as shown in Figure 2.
The utility model adopts following method to install: handle cable body 4 earlier well; Be installed to tail pipe 6 on the cable; Smear the lubricated silicone grease of one deck insulation at the surfaces externally and internally of cable body 4 outer surfaces and tail pipe 6, the surfaces externally and internally of seal member 5 again; Be installed to tail pipe and cable body insulation shielding outer surface to seal member 5, should guarantee cable body insulation shielding, seal member, tail pipe three's tight contact.The Installation Stress awl 3 then, connect the current-carrying part of stress cone, cable body insulation shielding, seal member, tail pipe with the conduction self-adhesive tape earlier, again with insulation self-adhesive tape fixed-link.Thereby can avoid because workmen's individual technological disparity, when holding self-adhesive tape, possibly occur holding bad, perhaps, make self-adhesive tape swelling in insulating oil, cause stress relaxation, thereby generation insulating oil leakage because self-adhesive tape directly contacts with insulating oil.
