Description

Externally-sleeved insulated sleeve
Technical field:
Patent of the present invention relates to a kind of sleeve pipe, relates in particular to a kind ofly directly to put insulating case at the electric conductor outer surface, has insulation property height, big, corrosion-resistant, the convenient externally-sleeved insulated sleeve of installing of tensile strength allowable stress.
Background technology:
Along with development of science and technology, the electric pressure of power transmission and transformation improves gradually, and the insulating requirements of conductor is also just more and more higher, occurred the cable from low pressure to the high pressure all size in the world in succession, voltage is high more, and the class of insulation of lead is also just high more, therefore, related technical difficulty also can strengthen thereupon.Simultaneously along with the raising of industrial expansion and living standards of the people, increasing gradually of power consumption causes continuing to increase of main transformer capacity, therefore to the requirement of bus ampacity also with on a new step.
Existing conductor mainly adopts the copper bar bus structure, mainly has following shortcoming: (1) is rectangular structure because of the single winding displacement of copper bar bus, and specification is roughly 10MM * 120MM, is easy to generate corona discharge at this row's bus water caltrop place, and coefficient of safety is not high; (2) because of the pipe bus has certain distance at transformer between the distribution box, need built on stilts the installation, the copper bar bus is easy to generate sagging because of own wt in built on stilts process, needs short distance to carry out shore supports during installation; (3) copper bar bus kelvin effect is big.
Summary of the invention:
Patent of the present invention is at above the deficiencies in the prior art, a kind of advantage of cable with hard bus of having drawn is provided, filled that original hard bus is wrapped to be easy to generate the shortcoming that the slit causes partial discharge, had insulation property height, big, corrosion-resistant, the convenient externally-sleeved insulated sleeve of installing of tensile strength allowable stress.
For realizing the above object, the technical scheme that patent of the present invention adopts is:
Externally-sleeved insulated sleeve is by: polyethylene glue connection material sleeve pipe; electric conductor; epoxy coating; aluminium foil; copper strips; semiconductive material; polytetrafluoroethylene film; the insulation busbar; outer jointing jacket; the silicone grease coating is formed; it is characterized in that; the electric conductor external structure is followed successively by: epoxy coating; polyethylene glue connection material sleeve pipe; aluminium foil; copper strips; semiconductive material; polytetrafluoroethylene film; the insulation busbar; outer jointing jacket; the silicone grease coating; concrete structure is: the electric conductor surface is coated with epoxy coating; polyethylene glue connection material casing pipe sleeve is contained in the electric conductor outside; aluminium foil is posted on polyethylene glue connection material surface; copper strips is attached on the aluminium foil surface; copper strips is derived as earth connection; semiconductive material surrounds on the copper strip surface; polytetrafluoroethylene film is wrapped to be compressed in the semiconductive material outside, is set with insulation busbar and outer jointing jacket at outermost layer.
Described polyethylene glue connection material sleeve pipe is divided into plurality of sections, there is being curved place to be divided into some segments, every section polyethylene glue connection material sleeve pipe head is provided with some projectioies, every section polyethylene glue connection material sleeve pipe afterbody is provided with some grooves, when connecting, every section polyethylene glue connection material sleeve pipe head bossing is inserted other end section polyethylene glue connection material sleeve pipe afterbody groove part, make both tight connectings by external force.
Described every section polyethylene glue connection material sleeve pipe head and afterbody are coated with epoxy coating, are used for filling breath.
The insulating sleeve outer jointing jacket surface that described suit is finished is coated with the silicone grease coating.
Patent of the present invention can solve following technical problem: (1) makes isolated bus can adapt to various environment because polyethylene glue connection material sleeve pipe has advantages such as heat-resisting, acid and alkali-resistance, corrosivity, prolongs isolated bus useful life; (2) compare with existing copper bar bus structure and increased allowable stress, can grow that distance is built on stilts installs, need not shore supports; (3) original copper bar bus water caltrop place is easy to generate corona discharge, and existing bushing type electric conductor is that cylindrical shape avoids producing electric discharge phenomena, the coefficient of safety height; (4) be coated with the silicone grease coating on the electric conductor surface, every section polyethylene glue connection stub bar portion and afterbody are coated with epoxy coating, are used for filling breath, help reducing partial discharge, and insulation property are reliable; (5) easy to process; (6) cost is low.

Fig. 2 is patent of invention polyethylene glue connection material sleeve pipe and electric conductor crook suit schematic diagram;
Fig. 3 is a patent of invention insulating sleeve integral installation schematic diagram;
Fig. 4 is a patent of invention insulating sleeve generalized section;
Embodiment:
As Fig. 1; shown in Figure 2; externally-sleeved insulated sleeve is by: polyethylene glue connection material sleeve pipe 1; electric conductor 2; epoxy coating 3; aluminium foil 4; copper strips 5; semiconductive material 6; polytetrafluoroethylene film 7; insulation busbar 8; outer jointing jacket 9; silicone grease coating 10 is formed; during concrete enforcement; the electric conductor 2 of selective rule shape; remove surperficial burr; remove surface dirt with the wipes of alcohol flush away; smear epoxy coating 3 on electric conductor 2 surfaces; main effect is the air gap of eliminating between electric conductor 2 and the polyethylene glue connection material 1; prevent partial discharge, suit polyethylene glue connection material sleeve pipe 1 on electric conductor 2.
As shown in Figure 1 and Figure 2, polyethylene glue connection material sleeve pipe 1 is divided into plurality of sections, there is being curved place to be divided into some segments, every section polyethylene glue connection material sleeve pipe 1 head is provided with some projectioies, every section polyethylene glue connection material sleeve pipe 1 afterbody is provided with some grooves, when connecting, every section polyethylene glue connection material sleeve pipe 1 head bossing is inserted other end section polyethylene glue connection material sleeve pipe 1 afterbody groove part, make both tight connectings by external force, every section polyethylene glue connection expects that sleeve pipe 1 head and afterbody are coated with epoxy coating 3 simultaneously, be used for filling breath, seal.
As shown in Figure 4, end to end polyethylene glue connection material sleeve pipe 1 is sleeved on behind electric conductor 2 surfaces the sleeve surface wiped clean, aluminium foil 4 is posted on the surface then, copper strips 5 is wrapped on aluminium foil 4 surfaces, copper strips 5 is derived as earth connection, manage under the bus insulation destruction situation in order to prevent on the one hand, short circuit appears in ground connection, shields; Make Leakage Current and surface volume electric current lead to the earth on the other hand by earth connection.Semiconductive material 6 surrounds on copper strips 5 surfaces, plays shielding action, evenly the distribution of voltage.Polytetrafluoroethylene film 7 is wrapped to be compressed in semiconductive material 6 outsides, is set with insulation busbar 8 and outer jointing jacket 9 at outermost layer at last, and insulating sleeve is played anticollision, radiation protection, suit is finished the insulating sleeve outer surface smear silicone grease coating 10.
