Fig. 4 is the plane graph of another embodiment of gas-insulated switchgear device of the present invention, and Fig. 5 is the front view of this embodiment, and Fig. 6 is an end view, only shows as Fig. 4 the breaking units shell of the three-phase shown in 5.
In this embodiment, the upper housing 9a of three-phase, 9b, 9c and downside shell 10a, 10b, 10c are arranged to more close mutually, have further increased spacing 12a as shown in fig. 1.That is to say, as Fig. 6 obviously as seen, extension 4a in the two-phase of both sides, 4c and 5a, 5c is arranged on each breaking units shell 6a, on the same height of 6c, and on the other hand, the extension 4b of middle phase, 5b be arranged on that breaking units shell 6b goes up and the differing heights of the extension of other two-phase on.Therefore, be arranged on equally highly with each extension mutually and compare, the upper housing 9a of this embodiment, 9c and downside shell 10a, 10c is provided with more closely.Have at gas-insulated switchgear device under the situation of this structure, when the multirow gas-insulated switchgear device was set as shown in Figure 1, the spacing 12a between the gas-insulated switchgear device of each row had further enlarged.
In addition, in the above-described embodiments, spacing 12a between the gas-insulated switchgear device of adjacent lines enlarges, obtained the space that to keep in repair and check the public operation unit, but, spacing between the upper and lower sides shell of the arbitrary phase of gas-insulated switchgear device of delegation has wherein also been enlarged, also obtained to carry out the public operation unit space of maintenance overhaul.In this case, the bearing of trend with upper and lower sides shell of the contiguous two-phase that enlarges spacing outwards is offset with respect to the central outrigger shaft of each breaking units shell.This structure from Fig. 1 obviously as seen.As supposition breaking units shell 6b, 6a, 6d and upper and lower sides shell 9b, 9a, 9d and 10b, 10a, 10d constitutes the gas-insulated switchgear device of delegation, and the upper and lower sides shell 9a of adjacent phase, 9d and 10a can form the spacing that public operation unit speech is had expansion between the 10d.
In addition, in the above-described embodiments, the gas-insulated switchgear device that is connecting has been described, but the principle of present embodiment also can be applicable to the gas-insulated switchgear device that connecting and the gas-insulated switchgear device of different size between bus and transformer between bus bar side and feeder line side.
In addition, in the above-described embodiments, breaking units shell 6a, 6c passes through extension 4a separately, 4c and 5a, the upper and lower sides shell 9a of the central outrigger shaft skew of 5c and bearing of trend and each breaking units shell, 9c and 10a, 10c is connected, therefore simplify their syndeton, and reduced upper and lower sides shell 9a separately, 9c and 10a, the axial length of 10c, but the shell that is connecting also can be arranged between extension and the upper and lower sides shell.
In the above-described embodiments, at least one setting like this in the upper and lower sides shell of the adjacent two-phase of gas-insulated switchgear device, just the center outrigger shaft skew of the bearing of trend of upper and lower sides shell and breaking units shell is opened, therefore between the upper and lower sides shell of the adjacent two-phase of the public operation unit of disconnect and earthing device, provide the space that enlarges, be arranged to coincide with all bearing of trends of upper and lower sides shell in the common unit and compare with the center outrigger shaft of separately breaking units shell, corresponding space is bigger among this embodiment, therefore under the situation in the occupation of land space that does not increase gas-insulated switchgear device, can be convenient to the maintenance and the inspection work of public operation unit.
The embodiment that has the gas-insulated switchgear device of transformer below with reference to Fig. 7 to Figure 14 explanation.
Fig. 7 is the plane graph of an embodiment of gas-insulated switchgear device of the present invention, it is based on the circuit structure in conjunction with Figure 18 explanation, the basic structure of each phase is with identical in conjunction with the embodiment of Figure 20 explanation, these parts are not elaborated, only to same or suitable element be marked with Figure 20 in identical label, different parts only is described below.
As can be known, in the gas-insulated switch unit of three-phase, the structure in the gas-insulated switch unit of the two-phase in two outsides is the same substantially from accompanying drawing, but middle then different mutually, the front view of this embodiment is shown in Fig. 8.Top and the bottom in the side of the breaking units shell 6a of vertical-type are provided with a pair of extension 4a, 5a, and upper and lower sides shell 9a, by current transformer CT2 and CT1 and lead division 4a, 5a's 10a is connected on their axis direction right side.As previously mentioned, disconnect and earthing device are installed in upper and lower sides shell 9a, in the 10a, and the public operation unit 20,21,22,23,24,25 that three disconnects and earthing device carry out switch are contained on their outer wall.The gas-insulated switch unit of a phase above in Fig. 7 comprises breaking units shell 6c, extension 4c, and 5c, transformer CT2, CT1 and upper and lower sides shell 9c, the structure of 10c is basic the same with the structure of a following phase.But disconnect and earthing device are carried out the operating unit 20,21,22,23 of switch, and 24 and 25 pairs of three-phases speeches are public, at upper and lower sides shell 9c, this operating unit are not installed on the outer wall of 10c.
The structure with other two-phase described above is identical basically for the structure of the gas-insulated switch of middle phase, but the position difference of current transformer CT1, CT2.That is to say that in the gas-insulated switchgear device of middle phase, current transformer CT2, CT1 are contained in upper and lower sides shell 9b, 10b near extension 4b, the 5b place, on the other hand, in the gas-insulated switchgear device of other two-phase that is located at two Outboard Sections, with middle current transformer CT2 mutually, CT1 compares their current transformer CT2, and CT1 is contained in upper and lower sides shell 9a separately, 9c, and 10a, last and the respectively extension 4a of 10c, 4c and 5a, the 5c place far away that is separated by.Therefore, the current transformer of adjacent phase is arranged to open partially along the bearing of trend of adorning the upper and lower sides shell of current transformer, make the upper and lower sides shell of three-phase be provided with very closely, and make reducing between the adjacent phase apart from 11a, this be adjacent distance between mutually with common gas-insulated switchgear device Comparatively speaking, in common device, the current transformer that diameter is bigger is contained in along them and extends axially direction separately on the same position of upper and lower sides shell.Therefore, corresponding this embodiment, distance 12 between adjacent lines enlarges, reduce corresponding to distance between adjacent phase 11a, and do not increase the occupation of land space of gas-insulated switchgear device, therefore reserved enough spaces of keeping in repair and checking work for the public operation unit of switch disconnect and earthing device.
Fig. 9 and 10 is respectively plane graph and the front view of another embodiment of the present invention.
Among the embodiment in front, current transformer CT2, the CT1 of the gas-insulated switchgear device of middle phase is provided with to such an extent that draw closer together with breaking units shell 6b than current transformer CT2, the CT1 of the gas-insulated switchgear device of other two-phase, and a pair of current transformer CT2, the CT1 that is to say homophase are in the relation of being arranged to consistency from top to bottom from the same distance of corresponding breaking units shell.But in the present invention, this from corresponding breaking units shell to same phase changes the distance current transformer CT2, the CT1.That is to say, in the middle of relate to during the gas-insulated switchgear device of phase, be contained in current transformer CT2 on the upper housing 9b and be positioned at breaking units shell 6b more closely, and be contained in current transformer CT1 and breaking units shell 6b on the downside shell 10b apart from far away.On the other hand, structure at the gas-insulated switchgear device of other two-phases in two outsides is basic identical, as long as the structure of one of them is described, the current transformer CT2 and the breaking units shell 6a distance that are contained on the upper housing 9a are far away, and the current transformer CT1 that is contained on the downside shell 10a is nearer from the distance of breaking units shell 6a than this current transformer CT2 that is contained on the upper housing 9a.
According to this embodiment, be contained in a pair of current transformer CT2 of vicinity of the same phase on the upper and lower sides shell and the position of CT1 respectively and open along their bearing of trend skew, the distance between extension 4a, the 5a is reduced, as shown in figure 10.Therefore make the contraction in length of the axle of the cell enclosure 6a that opens circuit in the gas-insulated switchgear device.That is to say that upper housing 9a and downside shell 10a can draw closer together the lower end that the upper end that makes current transformer CT1 is higher than current transformer CT2.
In Fig. 7 and embodiment shown in Figure 8, the current transformer CT2 that on the upper and lower sides shell of the two-phase in two outsides, is adorning, CT1, with middle current transformer CT2 mutually, the position of CT1 is compared, and leaves breaking units shell 6a separately, and the distance of 6c is farther.But the current transformer CT2, the CT1 that are located in contrast, the two-phase in two outsides also can be provided with than the more close breaking units shell 6a separately of the current transformer of middle phase, 6c.
Figure 11 and Figure 12 illustrate the plane graph and the end view of major part of the another embodiment of gas-insulated switchgear device of the present invention respectively.
In this embodiment, it is basic identical to be located at the structure of the structure of gas-insulated switchgear device of two-phase in two outsides and Figure 19 and common device shown in Figure 20.But for the gas-insulated switch unit of middle phase, the extension 4b of breaking units shell 6b is positioned at than breaking units shell 6a, the extension 4a of 6c, and 4c is low.Though do not illustrate in the drawings, in the middle of the following extension 5b of phase at above-below direction also with respect to following extension 5a in other two-phase in the outside, the 5c skew is opened.Therefore,, current transformer CT2 concerns the extension 4a that forms with skew when being arranged on along the vertical direction, each upper housing 9a that 4b is connected with 4c, and 9b, when 9c is last, reducing between the upper housing of contiguous phase apart from 11a, and do not hindered by the current transformer CT2 of each phase.In this embodiment, though the transformer of contiguous phase does not leave partially along the direction that extends axially of upper and lower sides shell, but the distance images front between the adjacent phase implements to reduce like that, reduces corresponding to this, does not make the occupation of land space enlargement of gas-insulated switchgear device between adjacent lines apart from increasing.Like this, just there are enough spaces of keeping in repair and checking the public operation unit.In addition, according to present embodiment, the arrangement principle of current transformer is that the current transformer of contiguous phase removes along the vertical direction, can be used for as Fig. 7 to gas-insulated switchgear device shown in Figure 10, can further dwindle in contiguous distance between mutually.
Figure 13 is the cross-sectional view of the major part of an embodiment again that gas-insulated switchgear device of the present invention is shown.
The complete gas-insulated switchgear device of three-phase is shown in this embodiment, and wherein current transformer CT1a, CT1b, the CT1c of three-phase are contained in the public shell 15.This public shell 15 is not shown with a breaking units shell extension 5() be connected, the current transformer CT1a of each contiguous phase, CT1b, CT1c are arranged to open with the direction skew that extends axially of public shell 15.In addition, because current 18a, 18b, 18c are arranged on each summit of imaginary rectangle, and be such as known in the art.Just obtained a three-phase complete gas-insulated switchgear device that has as Fig. 7 and combining structure embodiment illustrated in fig. 12.Therefore, the current 18a of three-phase, 18b, 18c are provided with to such an extent that lean on very closely mutually, and the distance between the adjacent row is enlarged, and make the public operation unit that enough spaces of keeping in repair and checking be arranged.
Figure 14 is the front view of another embodiment of gas-insulated switchgear device of the present invention.
