Description
Technical field
The utility model is related to a kind of insulation of second third copper pipe bus transition joint annex, belongs to electrical equipment technical field.
Background technology
With China's expanding economy, power load is continuously increased, and transforming plant main transformer capacity is continued to increase, transformer
10kV inlet wire side bus rated current are increasing, conventional copper bar and rectangular bus bar technically with structure be difficult meet bus
Heating and the requirement of short-circuit electromotive force, thus cause the increase of added losses, skin effect coefficient, cause under the ability of damming
Drop, CURRENT DISTRIBUTION are uneven.
New cast isolated bus a kind of in recent years gradually obtains national grid and various large enterprises are approved, still
There are many problems to exist in actual applications, such as every section of connection processing of isolated bus, by tube type bus production structure institute
Limitation, every bus length is most long 9 meters, the bending for also having various angles in live laid processes, safety between bus and bus
Connection is to be related to one of key point of whole piece bus safe operation, and it is disconnected that prior art not can solve bus insulation shielding
The electric field and voltage uniformity problem of mouth.Because existing insulating tube type busbar has conductor, conductor shielding, insulation and insulation shielding,
Insulation shielding section field intensity is uneven in the process of running, such as uneven insulation shielding fracture electric field, then isolated bus joint
It will irregularly be discharged in operation, cause accident, many enterprises of Current Domestic solve terminal using around packet mode terminal
Problems of The Electric Field, but this mode complex process, high to wrapped level requirement, around-packing technology is unstable, in running easily
Generation hidden danger.
The content of the invention
The utility model will solve technical problem：Overcome the shortcoming of above-mentioned technology.There is provided a kind of solution insulating tube type female
The transition joint voltage of line, the insulation copper pipe bus transition joint annex of second third of Problems of The Electric Field.
In order to solve the above-mentioned technical problem, the utility model proposes technical scheme be：A kind of insulation of second third copper pipe bus
Transition joint annex, including：Hollow shielded-plate tube, the insulation tube being wrapped in outside the shielded-plate tube, positioned at the insulation tube two ends
Semiconductive stress cone；The semiconductive stress cone be hollow truncated cone-shaped, the big one end of its radius towards the insulation tube simultaneously
Wrapped up by the insulation tube；The insulation tube outer surface is coated with conductive silicon rubber.
Such scheme is further improved：The insulation tube forms for the transparent high temperature vulcanized molding of silicon rubber.
Such scheme is further improved：The outer surface of the semiconductive stress cone is enclosed with transparent rubber insulation
Layer, the transparent rubber insulating barrier outer surface is coated with conductive silicon rubber.
The insulation copper pipe bus transition joint annex of second third that the utility model is provided, insulated part uses transparency liquid silicon rubber
Glue makes, and dielectric strength and transparency are all very high, and field intensity processing in insulating tube type busbar transition joint external screen fracture two ends is adopted
With the semiconductive stress cone after liquid curing, using bell shape, overlap, reach uniform with insulating tube type busbar insulation shielding
The effect of insulation shielding, makes insulation shielding fracture radial field and longitudinal field intensity obtain perfect uniform.Outsourcing is bored in semiconductive
Cover the insulating barrier of layer of transparent silicon rubber, insulating barrier can ensure the uniform of voltage on the outside of semiconductive well, and insulating barrier is transparent
What can be will be apparent that in silicon rubber, manufacturing process sees impurity clearly, reduces because the impurity removal of the opaque use of rubber color is tested, insulation
Layer one layer of conductive silicon rubber of trypsin method, is used as transition joint insulation shielding.The utility model can perfectly solve insulation
The transition joint voltage of tube type bus, Problems of The Electric Field, safety guarantee is provided for substation operation, is reduced because insulating tube type is female
Related accidents and problem caused by line transition joint annex.Simple installation is easy to operate, with the exclusive expansion of the utility model during installation
Technology by product and be expanded to greatly with bus bulk 10mm, by peculiar support bar pull out.The utility model is provided simultaneously with preventing
Water, antifouling and preferable weather resistance, resistance to IV grade of gradation for surface pollution, weather-proof 45 DEG C of -40 DEG C of high temperature resistants of low temperature whole nation on probation are most of
Area is applicable.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is a preferred embodiment structural representation of the utility model embodiment.
Fig. 2 is Fig. 1 A-A to cross section structure diagram.
Label is schematically as follows in figure：1- insulation tubes, 2- shielded-plate tubes, 3- semiconductive stress cones.
Embodiment
Embodiment
The insulation copper pipe bus transition joint annex of second third of the present embodiment, as depicted in figs. 1 and 2, including：Hollow shielding
Pipe 2, the insulation tube 1 being wrapped in outside shielded-plate tube 2, the semiconductive stress cone 3 positioned at the two ends of insulation tube 1；During semiconductive stress cone 3 is
Empty truncated cone-shaped, the big one end of its radius is wrapped up towards insulation tube 1 and by insulation tube 1；The outer surface of insulation tube 1 is coated with conductive silicon
Rubber formation screen layer.
Insulation tube 1 is to use liquid silastic material, is formed through high temperature vulcanized molding, dielectric strength and transparency are all very
Height.The outer surface of semiconductive stress cone 3 is enclosed with transparent rubber insulating barrier, and transparent rubber insulating barrier outer surface is coated with conduction
Silicon rubber.
Semiconductive stress cone, is overlapped with insulating tube type busbar insulation shielding, is reached the effect of uniform insulation shielding, is made insulation
Shielding fracture radial field and longitudinal field intensity obtain perfect uniform.
The utility model is not limited to the concrete technical scheme described in above-described embodiment, in addition to the implementation, this practicality
It is new to have other embodiment.The technical scheme of all use equivalent formation, is the guarantor of the utility model requirement
Protect scope.
