Abstract

The utility model discloses a kind of 110kV dry outdoor terminals tail pipes, it is characterised in that including tail pipe ontology, the tail pipe ontology is Concentric Reducers, outer in the middle part of tail pipe ontology to be arranged with epoxy resins insulation casing, and ground terminal is equipped in the rear end of tail pipe ontology.The utility model tail pipe leading portion tube body comes into full contact with semiconductive inner cone rear portion in 110kV dry outdoor terminal stress cones and ensure that good ground connection, the step of epoxy resins insulation casing, leading portion tube body and stage casing tube body junction plays the role of terminal limit when mounted, intermediate groove position cable anchor ear fixed position ensures terminal lower end not inclination and distortion at runtime;When being installed with electrical cable aluminium sheath, the fixed ear dead earth line of ground terminal, fingertip spring is wound on cable aluminium bellows, and after tail pipe puts on cable, fingertip spring is in close contact with tail pipe stage casing inboard wall of tube body, realizes electrical connection.

Description

A kind of 110kV dry outdoor terminals tail pipe
Technical field
The utility model is related to a kind of 110kV dry outdoor terminals tail pipe, specifically a kind of 110kV is crosslinked polyetylene insulated Power cable dry outdoor terminal tail pipe.
Background technology
110kV cross-linked polyethylene insulated cables power cable dry outdoor terminal tail pipe and electrical cable aluminium sheath all use sealing lead work Skill, sealing lead each serve as sealing and are electrically connected the two effects.Aluminium sheath need to be heated at high temperature when sealing lead, heating leads to cable sheet Body there is a possibility that damage;In addition lead is high potential metal, and electrochemical reaction easily occurs with aluminium, sealing lead is caused to loosen, and is sealed Property and electrical connection performance cannot get effective guarantee.
Utility model content
The purpose of this utility model is to provide a kind of 110kV dry outdoor terminals tail pipe.
The purpose of this utility model is achieved through the following technical solutions:
A kind of 110kV dry outdoor terminals tail pipe, including tail pipe ontology 1, the tail pipe ontology 1 is Concentric Reducers, in tail 1 middle part of tube body is outer to be arranged with epoxy resins insulation casing 2, and ground terminal 3 is equipped in the rear end of tail pipe ontology 1.
Preferably, the tail pipe ontology 1 is sequentially increased by diameter leading portion tube body, stage casing tube body, back segment tube body and Connect the annulus composition of adjacent both ends tube body.Tail pipe ontology 1 is one-pass molding.Two sides of the axial cross section of tail pipe ontology 1 are in It is step-like.
Fingertip spring is equipped in the stage casing tube body to be used to be in close contact realization electrical connection with electrical cable aluminium sheath.
The material of the tail pipe ontology 1 is aluminium alloy.
The ground terminal 3 is equipped with fixed ear and is used for dead earth line.
The beneficial effects of the utility model:
The leading portion tube body of the utility model tail pipe fully connects with 4 rear portion of semiconductive inner cone in 110kV dry outdoor terminal stress cones It touches, since terminal semiconductive position is just overlapped with cable semi-conductive mouth 5, electric field strength highest, semiconductive position are necessary herein There are good ground connection, tail pipe leading portion tube body to come into full contact with and ensure that with semiconductive inner cone rear portion in 110kV dry outdoor terminal stress cones The step of good ground connection, epoxy resins insulation casing, leading portion tube body and stage casing tube body junction plays terminal limit when mounted The effect of position, intermediate groove position cable anchor ear fixed position ensure terminal lower end not inclination and distortion at runtime;With electricity When cable aluminium sheath is installed, the fixed ear dead earth line of ground terminal, fingertip spring 6 is wound on cable aluminium bellows, tail pipe set After upper cable, fingertip spring is in close contact with tail pipe stage casing inboard wall of tube body, realizes electrical connection;Tail pipe back segment tube body be sealing and Glass fibre epoxy when installation, successively in the wrapped water blocking tape of tail pipe back segment tube body, glass fibre epoxy armoring tape, is waited in stabilization zone One layer of heat-shrink tube is shunk again after armoring tape solidification, is respectively formed waterproof sealing layer 7, armouring reinforcing layer 8 and pyrocondensation sealant 9, is had Have the advantages that good waterproof performance, intensity are high, against weather is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model 110kV dry outdoor terminal tail pipes.
Fig. 2 is the application schematic diagram of the utility model 110kV dry outdoor terminal tail pipes.
In figure, 1- tail pipe ontologies, 2- epoxy resins insulation casings, 3- ground terminals, 4- semiconductive inner cones, 5- cables partly lead Power port, 6- fingertip springs, 7- waterproof sealing layers, 8- armouring reinforcing layers, 9- pyrocondensation sealants.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of 110kV power cable with cross-linked polyethylene insulations dry outdoor terminal tail pipe, including tail pipe ontology 1, Tail pipe ontology 1 is Concentric Reducers, by leading portion tube body, stage casing tube body, back segment tube body and the annulus for connecting adjacent both ends tube body Composition, is arranged with epoxy resins insulation casing 2, in tail pipe outside the leading portion tube body rear portion of tail pipe ontology 1 and stage casing tube body front The stage casing tube body rear portion of ontology 1 is equipped with ground terminal 3.
The tail pipe ontology 1 is one-pass molding, and material is aluminium alloy.
Fingertip spring is equipped in the stage casing tube body to be used to be in close contact realization electrical connection with electrical cable aluminium sheath.
The ground terminal 3 is equipped with fixed ear and is used for dead earth line.
The leading portion tube body of the present embodiment tail pipe comes into full contact with 4 rear portion of semiconductive inner cone in 110kV dry outdoor terminal stress cones, Since terminal semiconductive position is just overlapped with cable semi-conductive mouth 5, electric field strength highest, semiconductive position must have good herein Good ground connection, tail pipe leading portion tube body come into full contact with semiconductive inner cone rear portion in 110kV dry outdoor terminal stress cones and ensure that well Ground connection, the step of epoxy resins insulation casing, leading portion tube body and stage casing tube body junction plays terminal limit when mounted Effect, intermediate groove position cable anchor ear fixed position ensure terminal lower end not inclination and distortion at runtime;With cable aluminium When sheath is installed, the fixed ear dead earth line of ground terminal, fingertip spring 6 is wound on cable aluminium bellows, and tail pipe set powers on After cable, fingertip spring is in close contact with tail pipe stage casing inboard wall of tube body, realizes electrical connection;Tail pipe back segment tube body is sealing and reinforces Area when installation, successively in the wrapped water blocking tape of tail pipe back segment tube body, glass fibre epoxy armoring tape, waits for glass fibre epoxy armouring One layer of heat-shrink tube is shunk again after band solidification, is respectively formed waterproof sealing layer 7, armouring reinforcing layer 8 and pyrocondensation sealant 9, is had anti- Aqueous advantage good, intensity is high, against weather is good.
