Description
Technical field
The present invention relates to cable connector, particularly to the conductor crimping structure of a kind of oil-filled cable joint, it is adaptable to 66kV
～500kV oil-filled cable joint.
Background technology
At present, known crosslinked cable joint conductor connection is made up of cable core, aluminium hydraulic pressed connecting pipe, radome.Connect
Technique is that aluminium hydraulic pressed connecting pipe is inserted in crimping after cable core, and aluminium hydraulic pressed connecting pipe profile is designed as cylinder, can be had by additional radome
Effect uniform inner electric field.But oil-filled cable is different from crosslinked cable, oil-filled cable core internal generally hollow structure, hollow
Part is as oil duct, and core can not directly crimp, need supporter, otherwise can destroy oil duct.Oil-filled cable joint needs
Wrapped paper roll recovers insulation, if directly used between crosslinked cable aluminium hydraulic pressed connecting pipe contour structures, and cable paper insulating conical face
There is step, be unfavorable for that wrapped filling is insulated.
It addition, during wrapped oil-filled cable joint paper roll, expose the manual operations time in atmosphere longer, insulation
In can absorb some moisture, ply of paper has also been embedded large quantity of air.Therefore evacuation process must be carried out after making terminates, and
Under vacuo qualified cable oil is injected in transition joint.During evacuation, can suitably open and be connected on cable
Forbay, makes a small amount of cable oil ooze out from insulation, with oil purging, improves degassing effect, but oil-filled cable may be made to connect
Head is internal exists oil accumulation, affects the performance of oil-filled cable joint.
Summary of the invention
It is an object of the invention to provide the conductor crimping structure of a kind of oil-filled cable joint, mainly solve oil-filled cable and connect
The internal technical problem producing oil accumulation of head.
Technical scheme: the conductor crimping structure of a kind of oil-filled cable joint, two lining cores are lining in two respectively
In oil-filled cable central oil passage, two sections of cable cores penetrate from the two ends of aluminium hydraulic pressed connecting pipe respectively, and make the contact of two cable cores
Point is positioned at aluminium hydraulic pressed connecting pipe center, fixes aluminium hydraulic pressed connecting pipe by fixing bolt, uses pressing mold to crimp aluminium hydraulic pressed connecting pipe, aluminium hydraulic pressed connecting pipe periphery
Face is wrapped fills insulation.
Described lining core in a tubular form, is lining on the medial wall of central oil passage, and end-beveling also has male and fomale(M&F) on outer peripheral face
Section.
Described aluminium hydraulic pressed connecting pipe is pressed in the outside of cable core, the most outside diminishing taper of outer peripheral face at two ends
Face, it is easy to wrapped filling is insulated, homogenizing electric field；Oil through, the cable oil in crimping rear center oil duct it is designed with in the middle part of aluminium hydraulic pressed connecting pipe
Flow into oil-filled cable joint by oil through to fill in insulation.
The invention has the beneficial effects as follows: present invention can ensure that the electrical communication of cable core after crimping, mechanical strength and
Oil circuit is unimpeded.When the design of aluminium hydraulic pressed connecting pipe two ends taper surface makes lapped insulation paper roll tight as far as possible, prevent that local is the softest
Point, makes internal field's homogenizing simultaneously.The design of aluminium hydraulic pressed connecting pipe oil through improves degassing effect, solves oil-filled cable transition joint
The internal problem producing oil accumulation, insulating oil is saturated with in whole paper insulation, improves electrical strength, it is ensured that oil-filled cable joint
Longtime running under high voltages.

Detailed description of the invention
With reference to Fig. 1, the conductor crimping structure of a kind of oil-filled cable 1 joint, two lining cores 4 are lining in two oil-filled cables respectively
In central oil passage 3, two sections of cable cores 2 penetrate from the two ends of aluminium hydraulic pressed connecting pipe 6 respectively, and make the contact point position of two cable cores 2
In aluminium hydraulic pressed connecting pipe 6 center, fix aluminium hydraulic pressed connecting pipe 6 by fixing bolt 5, use pressing mold aluminium hydraulic pressed connecting pipe 6 to be crimped, outside aluminium hydraulic pressed connecting pipe 6
Side face wrapped filling insulation 8.Described lining core 4 in a tubular form, is lining on the medial wall of central oil passage 3, end-beveling at outer peripheral face
On there is male and fomale(M&F) section.Described aluminium hydraulic pressed connecting pipe 6 is pressed in outside the 2 of cable core, and the outer peripheral face at aluminium hydraulic pressed connecting pipe 6 two ends is the most outside
Diminishing taper surface, it is easy to wrapped filling insulation 8, homogenizing electric field；Be designed with oil through 7 in the middle part of aluminium hydraulic pressed connecting pipe 6, after crimping in
Cable oil in heart oil duct flows into oil-filled cable joint by oil through 7 and fills in insulation 8.
