Silicon rubber umbrella skirt (not shown) on surface.
The embodiment of insulator
To illustrate one of the insulator including aforementioned dielectric sleeve pipe referring to Figure 13 to Figure 15
Embodiment.
Figure 13 shows that the longitudinal direction of the insulator of the embodiment according to an example of the present invention is cutd open
View；Show the schematic perspective view of the insulating base 340 of insulator in Figure 13 with Figure 14.
In the embodiment of an example of the present invention, disclose a kind of insulator.As figure
Shown in 13 and Figure 14, it (can also be aforementioned exhausted that this insulator mainly includes insulated sleeve 100
Edge sleeve pipe 200), insulation cluster parachute 330, outlet end cap 360 and insulating base 340.
As shown in figure 13, in the illustrated embodiment, insulated sleeve 100 has arrival end 100a
(lower end in Figure 13) and the port of export 100b relative with arrival end 100a are (in Figure 13
Upper end).Insulation cluster parachute 330 is formed on the outer wall of insulated sleeve 100.Metal outlet
End cap 360 is sealably mounted in the outlet of insulated sleeve 100.
Continuing with referring to Figure 13, in one embodiment of the invention, in insulated sleeve 100
Inner space 301 in be filled with insulating gas or iknsulating liquid, for example, SF6 gas.From
Electric equipment (not shown), for example, transformator or chopper, the current－carrying conductor 310 of extraction
From the entrance of insulated sleeve 100 be introduced into insulated sleeve 100 and be arranged on insulated sleeve 100
Outlet on outlet end cap 360 electrically connect.
In the illustrated embodiment, as shown in Figure 13 and Figure 14, insulating base 340 is to pass through
The unitary members that pressing process is disposably formed.In the illustrated embodiment, insulating base
340 include integral part of insulating flange 341 and insulation connecting tube 342.Insulating flange 341
It is formed on the base portion of insulation connecting tube 342, and be adapted to be mounted on the housing of electric equipment.
Insulation connecting tube 342 is connected with the arrival end 100a of insulated sleeve 100.
As Figure 14 clearly illustrates, multiple installing hole 341a are formed with insulating flange 341,
Insulating flange 341 can be by the multiple bolts connection (not shown) through installing hole 341a
To on the housing of electric equipment.
Continuing with referring to Figure 14, in the illustrated embodiment, insulating base 340 also include with
Insulating flange 341 and the insulation integral part of multiple insulating strength muscle 343 of connecting tube 342.Often
Individual insulating strength muscle 343 is connected respectively to outer wall and the insulation connecting tube 342 of insulating flange 341
Outer wall on so that improve insulating flange 341 and insulation connecting tube 342 between bond strength.
In the illustrated embodiment, as shown in figure 14, multiple insulating strength muscle 343 are around exhausted
The base portion uniform intervals distribution of edge connecting tube 342.
As shown in Figure 13 and Figure 14, in the embodiment of an example of the present invention, insulation
Connecting tube 342 includes the first pipe portion 342a, the second pipe portion 342c and the 3rd pipe portion 342b.The
One pipe portion 342a is located at one end of the close insulating flange 341 of insulation connecting tube 342；Second
Pipe portion 342c is located at the other end away from insulating flange 341 of insulation connecting tube 342；3rd
Pipe portion 342b is located between the first pipe portion 342a and the second pipe portion 342c.As Figure 13 and Figure 14
Shown, the first pipe portion 342a has first external diameter, and the second pipe portion 342c has outside less than first
The second external diameter in footpath, and the 3rd pipe portion 342b has and is gradient to second external diameter from first external diameter
Gradual change external diameter.
So, insulated sleeve 100 just must not be matched with the insulating flange 341 being relatively large in diameter,
And only need second pipe portion 342c less with diameter to match, it therefore reduces insulated sleeve
100 diameter, decreases the quantity of material manufacturing insulated sleeve 100, reduces manufacturing cost.
Additionally, in previously described embodiments of the present invention, the lower face of insulation connecting tube 342 is in charge of
Internal diameter is big compared with top bore, and the lower part of the connecting tube 342 that insulate exactly electric field is relatively
The place concentrated, thus more effectively improve insulation service efficiency, and need not entirely be insulated
Connecting tube 342 and insulated sleeve 100 are made equally big, have saved material.
In the illustrated embodiment, as shown in Figure 13 and Figure 14, the internal diameter of insulated sleeve 100
It is slightly larger than the external diameter of the second pipe portion 342c of insulation connecting tube 342 and be less than the first pipe portion 342a
External diameter.The arrival end 100a of insulated sleeve 100 is hermetically socketed in insulation connecting tube 342
The second pipe portion 342c outside.
However, it is noted that the present invention is not limited to the embodiment illustrating, another in the present invention
In individual embodiment, for example, as shown in figure 15, the external diameter of insulated sleeve 100 can be slightly smaller than
The internal diameter of the second pipe portion 342 ' of insulation connecting tube 342.So, the of insulation connecting tube 342
Two pipe portions 342 ' can hermetically be socketed in outside the arrival end 100a of insulated sleeve 100.
In the embodiment of an example of the present invention, insulating base 340 and insulated sleeve
100 can be made up of identical insulant, and thermal coefficient of expansion so between the two will phase
Same, therefore, just it is not easy that gap occurs between the two.
In the embodiment of an example of the present invention, insulated sleeve 100 is to be soaked by winding
The winding pipe that the glass fibre of stain epoxy resin is made.Insulating base 340 is to be soaked by compacting
The rolled-up stock that the glass fibre of stain epoxy resin is made.In the illustrated embodiment, insulation sleeve
The port of export 100b of pipe 100 is hermetically wrapped in the second pipe portion 342c of insulation connecting tube 342
On, thus defining the sealing structure of an entirety, improve insulator air-tightness.
As shown in Figure 13 and Figure 14, in the illustrated embodiment, insulator also includes outside and connects
Line row 370, this external cabling row 370 is removably mounted at outlet end cap 360
On outer wall.For example, it is arranged on threadably on outlet end cap 360.
In the embodiment of an example of the present invention, as shown in Figure 13 and Figure 14, insulate
Son also includes high-tension shielding ring 380, and this high-tension shielding ring 380 is removably mounted at
On the outer wall of outlet end cap 360, and arrange 370 around external cabling.High-tension shielding ring 380
For making external cabling arrange the electric field homogenizing of 370 generations, prevent concentration electric discharge.
In the embodiment of an example of the present invention, as shown in Figure 13 and Figure 14, insulate
Son also includes tubular base portion shielding 350, and this tubular base portion shielding 350 is contained in insulation connecting tube
In 342, and around current－carrying conductor 310.Tubular base portion shielding 350 is used for making current－carrying conductor 310
The electric field homogenizing producing at insulating base 340, prevents concentration electric discharge.
In one embodiment of the invention, as shown in Figure 13 and Figure 14, in described insulation method
Formed fluted on blue 341 bottom surface, the edge part of described tubular base portion shielding 350 is assemblied in
In groove on the bottom surface of described insulating flange 341.
Note that the insulator of the present invention can be not only used for transformator or the extraction of chopper is led
The insulation of line, can be also used for the insulation terminal of high tension cable.
In the present invention, due to the insulation for being installed to insulator on the housing of electric equipment
Pedestal is to be made with cheap insulant, rather than expensive metal, therefore,
Reduce manufacturing cost.Additionally, easily be combineding with each other between insulating base and insulating sleeve, and
And similar thermal expansion coefficient between the two or identical, therefore, it is not easy that seam occurs between the two
Gap, improves sealing property.
