Abstract
The utility model discloses a 110 kV to 220 kV crosslinked cable oil-filled outdoor terminal, which comprises a stress cone, an epoxy silicone rubber sleeve (or a porcelain sleeve), a sleeve upper flange, a sleeve lower flange, a platen, an oil-tight ferrule, a ferrule gasket, a tail pipe and insulating oil. The utility model is characterized in that: the oil-tight ferrule ensures that the insulating oil inside the sleeve enclasps a cable body at one end; and the lower flange adopts a bolt to press the oil-tight ferrule so as to prevent the leakage of the insulating oil. The crosslinked cable oil-filled outdoor terminal can ensure evener electric field distribution at a cable insulation shielding cut part and stable electrical property of a cable termination; meanwhile, the outdoor terminal, which accords with the national standards and the standards of the International Electric-technical Commission (IEC), optimizes the oil-tight structure of the cable termination, thereby ensuring a simpler and more reasonable structure.
Description
Technical field:
The utility model is meant the HV XLPE Power Cable outdoor terminal, is applicable to the 110kV-220kV crosslinked cable.
Background technology:
The crosslinked cable terminal just is being widely used in the net of city, because the electric field of insulation shield cut-off part is very concentrated, so 6kV and above electric pressure cable in use all adopt a kind of stress cone that has the oviduct shape of making of semiconductive material to improve herein Electric Field Distribution, referring to the patent No. 02261002.2 Chinese patent.At present, after the hv cable termination of use adopted stress cone to install more, the structure that insulating tape or use " O " sealing ring are twined in the bottom prevented the insulating oil leakage.But this structural requirement stress cone material must match with insulating oil, and the sealing of insulating oil should be specifically noted that otherwise oil leakage phenomenon can occur.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of oil-filled outdoor terminal of crosslinked cable that is applicable to the 110kV-220kV electric pressure of design,
The technical solution of the utility model is, the oil-filled outdoor terminal of a kind of 110kV-220kV crosslinked cable, its composition comprises lower flange 3, platen 4, oil seal lasso 5, lasso pad 6, tail pipe 7, insulating oil 8 on stress cone 1, epoxy-silicone rubber sleeve pipe (or porcelain bushing) 2, the sleeve pipe, it is characterized in that: hold the insulating oil in the sleeve pipe 8 tightly cable body by an end with oil seal lasso 5, and issue blue 3 and use bolts to compress oil seal lasso 5 planes to prevent the insulating oil leakage of oil that leaks.
Described oil seal lasso 5 one ends are that taper or cast and cable body insulation shielding form sealing to cover; The other end is the face-flange shape, by cable termination lower flange 3 and platen 4 it is compressed sealing.
Described stress cone 1 adopt firm silicone rubber by twice or multiple injection moulding have the parts of certain geometry in conjunction with shape, wherein form one section straight line, two sections curves by three line segments with the inner surface of the tubaeform member of semi-conducting material manufacturing.
Owing to use the novel sealing ring that prevents leakage of oil, make to install to be more prone to, be easy to grasp, seal more reliable; Firm silicone rubber by certain geometry and repeatedly the injecting glue moulding be used in the cable stress cone, bigger grip force can be provided, make the margin of safety of terminal stress cone greatly improve.

Embodiment:
The grease proofing leakage of cable outdoor terminal is a pith.What cable terminal insulation oil was revealed prevents it is one of crucial principle of Terminal Design, and what guarantee this key technology is the oil seal measure, and promptly an end is that taper or cast oil seal lasso and cable body insulation shielding form sealing; The other end is the face-flange shape, by cable termination lower flange and platen it is compressed sealing.Running quality guarantees the annex more than 20 years, can not guarantee safe operation if insulating oil is revealed.
The moulding of firm silicone rubber stress cone is the difficult problem of electric cable accessories industry always, because solids flowability problem, in having the tangent stress cone structure of straight line and circular arc, firm silicone rubber is difficult to flow near the point of contact the narrow and small zone, we have finished the manufacturing of firm silicone rubber stress cone by the design of special technology and mould and planform.
Oil-proof in order to guarantee 20 years run durations of cable termination, we have taked subordinate's solution (seeing accompanying drawing 2): cable termination inside is except installing conventional parts, the sealing ring 5 of a kind of uniqueness of its leakage-preventing place's specialized designs, the upper end that it has an awl dish be used for and insulation shield between form sealing; Has the flange shape.By pressing of cable termination lower flange 3 and pressure benefit 4 forming sealing, simultaneously, in order to adapt to the multiple cross-section of cable, wear the bore dia of cable position greater than the known maximum gauge of cable in the middle of the compression plate, by the lasso pad 6 of supporting different interior diameters, prevent the destruction of oil pressure to the sealing ring stage casing.In Fig. 2, the stress cone 1 of cable termination inside is to be made by conduction and insulating material to form, and the horn mouth shape inner surface that electric conducting material is made is to be formed by connecting by many curves, and the complete sum of curve keeps design shape directly to have influence on safe operation.Indeformable in the production in order to guarantee curve, just must adopt special planform and repeatedly the injecting glue method can obtain desirable finished product.
