It is arranged with vertical structure, according to the regulation of " Code for design of cables of electric works " (GB50217-2007), " cable is in any laying
The change position up and down of mode and its All Paths condition, should all meet cable allow bending radius requirement ", " cable
Allow bending radius, the requirement of Ying Fuhe cable insulation and its structural property.For self-tolerant sheath oil-filled cable, allow curved
Bilge radius can be by 20 times of calculating of the outside diameter of cable ", it needs to design biggish turning of cable space, excavates deeper cable duct.
110kV, 220kV high-tension cable are chiefly used in crosslinked polyetylene insulated Copper core power cable, section be often 400mm2 or
630mm2 is respectively as follows: 91.3 and 97.5mm for the 110kV outside diameter of cable according to producer's data, bending radius 1.8m when laying
With the bending radius 2.3m and 2.4m when 2.0m, operation；113.1mm2 and 118.3mm2 are respectively as follows: for the 220kV outside diameter of cable,
Bending radius 2.8m and 3m when bending radius 2.3m and 2.4m when laying, operation.In order to meet wanting for Cable Bending Radius
It asks, the depth of cable duct needs to reach 2.5~3 meters hereinafter, have the shortcomings that civil engineering high construction cost, project amount are big, long in time limit,
It is not easy to construction and installation and operation and maintenance again.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of GIS combination electric appliance equipment high-tension cables quickly to connect dress
It sets, applied to the connecting portion of combined electric appliance equipment and cable, realizing reduces civil engineering cost, reduce project amount, shorten the construction period
Purpose.
In order to solve the above technical problems, the present invention adopts the following technical scheme: GIS combination electric appliance equipment high-tension cable is quick
Attachment device, including cable termination cylinder and along the cable of cable duct laying, the cable has end, the end
It is inserted into cable termination inner barrel from cable termination cylinder body bottom, is equipped with the electricity connecting with end in the cable termination cylinder
Cable terminal connects conductor, it is characterised in that: the cable termination cylinder includes having folder perpendicular to the vertical section on ground, with ground
The angle section at angle and the arc transition section for connecting vertical section and angle section, the end are located at angle section, and the cable is whole
End connection conductor has the head end being located in vertical section and the tail end in arc transition section.
Preferably, the lower end of the cable termination cylinder is equipped at least one outlet hole.
Preferably, the cable termination cylinder is circumferentially distributed hand hole.
Preferably, the angle on the angle section and ground is 30 ° or 60 ° or 90 °.
The present invention is equipped with the angle section being tilted a certain angle in cable termination cylinder lower part, while cable termination connects conductor
Tail end also tilts respective angles, can be substantially reduced cable trench depth, plays optimization power distribution equipment place, reduces civil engineering
Amount, the effect reduce construction workload, shorten the construction period, operation and maintenance is facilitated to overhaul.
Detailed description of the invention
Present invention will be further described below with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the schematic diagram of the prior art；
Fig. 2 is structural schematic diagram of the invention.
Specific embodiment
The technical solution of the embodiment of the present invention is explained and illustrated below with reference to the attached drawing of the embodiment of the present invention, but under
It states embodiment to be merely a preferred embodiment of the present invention, and not all.Based on the implementation example in the implementation mode, those skilled in the art
Obtained other embodiments without making creative work, belong to protection scope of the present invention.
As shown in Fig. 2, GIS combination electric appliance equipment high-tension cable Quick Connect Kit, including cable termination cylinder 1 and electricity
The disconnecting switch of cable terminal cylinder upper end connection, the cable duct 3 below cable termination cylinder, the cable laid along cable duct
2, the cable have end, the end from cable termination cylinder body bottom be inserted into cable termination inner barrel, it is described every
It leaves pass and is equipped with disconnecting switch connection conductor, be equipped with cable termination in the cable termination cylinder and connect conductor, the cable is whole
End connection conductor connection disconnecting switch connection conductor and end.Wherein, the cable termination cylinder 1 includes perpendicular to ground
Vertical section 11 has the angle section 13 of angle with ground and connect the arc transition section 12 of vertical section and angle section, the electricity
Cable end is located at angle section, and the cable termination connection conductor has the head end being located in vertical section and is located in arc transition section
Tail end.
While cable termination cylinder 1 has angle, end part can also design angle, in order to install, when
So, angle can also be not provided with.It is unified that cable termination, which connects conductor and the angle design of cable termination cylinder 1,.
