Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 2, Figure 3, Figure 4, a kind of double-deck outlet structure suitable for GIS of the utility model, including three-phase two
Two are staggered GIS outlet casing tube 1 and be provided with upper layer crossbeam 21 and single Pin two of lower layer's crossbeam 22 returns back out line structure that front and back is arranged
Frame 2, the upper layer crossbeam 21 setting in outlet structure 2 from the closer truss column of GIS outlet casing tube 1, lower layer's crossbeam 22
It is arranged in outlet structure 2 from the farther away truss column of GIS outlet casing tube 1；The upper layer beam 31 is equipped with three outriggers 23, described to choose
Beam 23 is equipped with insulator chain 3；A, C phase outlet that the GIS outlet casing tube 1 first returns back out line are drawn by lower layer's crossbeam 22,
Lead is transitioned into upper layer crossbeam by the insulator chain 3 on outrigger 23 and drawn by the outlet of B phase, and B phase outlet is being located at the outlet of A phase just
Top, so that three-phase outlet spatially L-shaped arrangement；A, B phase that the second of the GIS outlet casing tube 1 returns back out line go out
Lead is transitioned into upper layer crossbeam 21 by the insulator chain 3 on outrigger 23 and drawn by line, and C phase outlet is drawn by lower layer's crossbeam 22
Out, and C phase outlet is located at immediately below the outlet of B phase, so that three-phase outlet is spatially in inverted " L " font arrangement；The GIS outlet
The A phase outlet that the second of casing 1 returns back out line is located at first and returns back out right above the c phase outlet of line.
Referring to Fig. 1 to Fig. 3, adjacent overhead outlet interval centre distance is a, due to using L-shaped respectively and falling
The outlet structure of "L" shaped, the A phase outlet that the second of GIS outlet casing tube 1 returns back out line are located at first and are returning back out the c phase outlet of line just
Top, therefore compared to original positive " product " word and " product " word outlet arrangement of falling, single Pin two, which returns outlet structure width, can reduce a/2.
Such as: according to national grid latest edition " universal design " and " common apparatus " scheme, in the adjacent overhead outlet interval of two of 220kv
Heart distance is 12 meters, and single Pin two, which returns outlet structure width, can reduce 6 meters, greatly save land resource.
Due to using the outlet structure of L-shaped and inverted " L " font respectively, the lead 5 of GIS outlet casing tube 1 be from
Ground guides outlet structure 2, therefore the second of A, B phase terminal of 1 first time lead of GIS outlet casing tube and GIS outlet casing tube 1 into
It returns back out the A phase terminal line of line and that c phase terminal that first returns back out line can lean on is relatively close.Draw to guarantee GIS outlet casing tube 1 first time
A, B phase terminal of line, the second of GIS outlet casing tube 1 return back out line A phase terminal line and first return back out line c phase terminal safety
Distance, therefore upper layer crossbeam 21 is arranged in outlet structure 2 from the closer truss column of GIS outlet casing tube 1, lower layer's crossbeam 22 is arranged
In outlet structure 2 from the farther away truss column of GIS outlet casing tube 1；Upper layer beam 31 is equipped with three outriggers 23, sets on the outrigger 23
There is insulator chain 3；The B phase outlet that GIS outlet casing tube 1 first returns back out line passes through the insulator chain 3 on outrigger 23 for lead transition
It is drawn to upper layer crossbeam.Be arranged in this way guarantee GIS outlet casing tube 1 outlet lead 5 between distance the case where meeting the requirements
Under, GIS outlet casing tube 1 can be as close as possible to outlet structure 2, so as to economize the land resource.
Further distance between the line lead 5 in order to guarantee GIS outlet casing tube 1, the GIS of every time GIS three-phase outlet go out
The arrangement in the shape of " pin " of thread casing 1, and A, C phase arrive the distance of outlet structure 2 apart from B phase is less than to outlet structure 2.
In order to guarantee the stress of upper layer crossbeam 21 and lower layer's crossbeam 22 and save material, upper layer crossbeam 21 and lower layer's crossbeam
22 use truss structure.
The long column braces for being equipped with line-styled or " X " font between the truss column of outlet structure 2, in order to guarantee outlet structure
The stability of frame is preferably provided with the column braces 6 in " X " font between the truss column of outlet structure 2.
