Description
Technical field
The present invention relates to realize being subjected to the gas-insulated switchgear device of converting equipment miniaturization, particularly the improvement of the arrangement of gas-insulated switchgear device.
Background technology
Gas-insulated switchgear device, in metallic cylindrical container inside, the gas of good insulating such as inclosure SF6, and, with insulation twelve Earthly Branches take-over point (this contact constitutes the switching of high-voltage conductor and this bus current of bus) such as insulation spacers, its economy and maintainability are good, so, occupy the main flow of newly-installed switching device in recent years.
Below with reference to Fig. 4 to Fig. 7, an example of the gas-insulated switchgear device in the prior art is described.
Fig. 4 is the single line tie lines figure of the gas-insulated switchgear device in the multiple bus mode of representing before.Fig. 5 is based on the side view of the gas-insulated switchgear device of single line tie lines figure shown in Figure 4.Fig. 6 is the front elevation of the gas-insulated switchgear device that mark 18 directions are seen from Fig. 5.Fig. 7 is the front elevation of the gas-insulated switchgear device that mark 19 directions are seen from Fig. 5.
As shown in Figure 4 and Figure 5, main bus bar is made of the 1st bus and the 2nd bus, on the 1st, the 2nd bus, 1,2, is connecting the 1st, the 2nd main bus bar grounding opening-closing device 3A, 3B and the 1st, the 2nd meter transformer 4A, 4B.
1st, the 2nd bus 1,2 and the 1st, the 2nd main bus bar constitute by omiting the cylindrical vessel one with grounding opening-closing device 3A, 3B, are provided with the 1st, the 2nd lead division 5A, the 5B that are connected usefulness with other machine.The 1st bus and the 2nd bus bar configuration are about the summary vertical line.As shown in Figure 6, in order to improve the operability of grounding opening-closing device 3A, 3B, minimum between the 1st bus and the 2nd bus.
The 2nd bus 2 is being supported by pallet 7B, directly is connected with the 2nd lead division 6B of the 2nd meter transformer 4B at lead division 5B place.
As shown in the figure, the interval of the 1st bus and the 2nd bus, littler than the body diameter of the 1st, the 2nd meter transformer 4A, 4B, so, the 1st bus 1 is connected the 1st bus lead division 5A by bus 8 with the 1st lead division 6A of the 1st meter transformer 4A, supported by the 1st pallet 7A and support 9.
In the lower space of the 1st bus 1 and the 2nd bus 2, disposing the control panel 10 of distribution mouth down, be fixed on the common substrate 12.Be connected the control cable 13 on each machinery compartment and the control panel 10, be connected with distribution mouth 11 by common substrate 12.
But there is following problem in above-mentioned gas-insulated switchgear device before.That is,,, the space is set increases so the 1st bus 1 is connected by bus 8 with the 1st meter transformer 4A because the interval of the 1st bus and the 2nd bus is littler than the diameter of the 1st, the 2nd meter transformer 4A, 4B.
In addition, supporting the 1st, the 2nd meter transformer 4A, 4B respectively by the 1st, the 2nd pallet 7A, 7B, and be fixed on the common substrate 10, so, less economical.
In order to address this problem, though take the measure drawn back in the vertical line direction between the 1st bus and the 2nd bus,, this measure makes the height dimension of machine strengthen.

Embodiment
Below, referring to figs. 1 through Fig. 3, an embodiment of gas-insulated switchgear device of the present invention is described.Among Fig. 1 to Fig. 3, annotate with same tag with part identical among Fig. 4 to Fig. 7, its explanation is omitted.Fig. 1 is the front elevation of the gas-insulated switchgear device seen of the mark 19 ' direction from Fig. 3.Fig. 2 is the front elevation of the gas-insulated switchgear device seen of the mark 18 ' direction from Fig. 3.
In the present embodiment, the 1st bus 1 and the 2nd bus 2 are located at the slightly bearing of trend of vertical line 17 stackedly, on the 1st, the 2nd bus 1,2, are respectively equipped with the 1st, the 2nd meter transformer 4A, 4B.The container central axis 14A of the 1st meter transformer 4A, with respect to central shaft 15A direction off-centre on the summary vertical line of lead division 5A, 6A, eccentric size is the size shown in the mark 16A.The container central axis 14B of the 2nd meter transformer 4B, with respect to central shaft 15B direction off-centre under the summary vertical line of lead division 5B, 6B, eccentric size is the size shown in the mark 16B.
In the present embodiment of Gou Chenging, the 1st, the 2nd meter transformer 4A, 4B can be stacked on the same vertical line 17 like this, line direction shortens, and the erection space of gas-insulated switchgear device is dwindled.
In addition, in the present embodiment, as shown in Figure 3, and on the 1st meter transformer 4A that is supporting by pallet 7, stacked the 2nd meter transformer 4B on same vertical line.1st, lead division 6A, the 6B of the 2nd meter transformer 4A, 4B are connected with bus bar side lead division 5A, 5B.This bus bar side lead division 5A, 5B are omiting on the cylindrical vessel, constitute with the 1st, the 2nd grounding opening-closing device 3A, 3B and the 1st, the 2nd bus 1,2 one.
In the present embodiment of this structure,, support the 1st, the 2nd grounding opening-closing device 3A, 3B and the 1st, the 2nd bus 1,2 with the summary cylindrical vessel of the 1st, the 2nd meter transformer 4A, 4B.Like this, can cancel and be used to support the instrument of connection bus (this connection bus is the connection bus of the 1st, the 2nd meter transformer 4A, 4B and the 1st, the 2nd bus 1,2) and the 1st bus with supporting pallet, can provide component number few, reduce cost, improve the gas-insulated switchgear device of reliability.
In addition, in the present embodiment, as shown in Figure 3, the side of main bus bar side at the pallet 7 of supporting the 2nd meter transformer 4B is installed with control panel 10.
In the present embodiment of this structure, owing to control panel 10 is fixed on the pallet 7 of supporting the 2nd meter transformer 4B, so, common substrate can be cancelled.Like this, because the cancellation common substrate, the center of gravity of reduction gas-insulated switchgear device can improve vibration strength.
In addition, in the present embodiment, as shown in Figure 3, control panel 10 (this control panel 10 be installed in the supporting the 2nd meter transformer 4B pallet 7 on) machine side distribution mouth 11 towards the 2nd bus bar side, that is, be configured in upside, control panel 10 be connected with each machine with control cable 13.
In the present embodiment of this structure,, can shorten control cable 13, reduce cost, improve operation owing to,, that is, be configured in upside towards the 2nd bus bar side the machine side distribution mouth 11 of control panel 10.
In addition, in the foregoing description, the off-centre of the central shaft of the container central axis of the off-centre of the central shaft of the container central axis of the 1st meter transformer 4A and lead division 5A, 6A and the 2nd meter transformer 4B and lead division 5B, 6B, be set in the slightly above-below direction of vertical line, but be not limited thereto, as long as can shorten line direction, the direction of above-mentioned off-centre and offset (mark 16A, 16B illustrated dimension) can be suitably selected as required.
As mentioned above,,, line direction can be shortened, like this, erection space can be dwindled because container central axis and lead division central shaft are eccentric respectively according to gas-insulated switchgear device of the present invention.
According to gas-insulated switchgear device of the present invention, be with 2 container central axis with respect to the lead division central shaft, direction and following direction off-centre on vertical line slightly, so, shorten line direction more, dwindle erection space more.
According to gas-insulated switchgear device of the present invention, component number is few, cost is low, reliability is high.
According to gas-insulated switchgear device of the present invention, owing to can cancel common substrate, so center of gravity reduces, vibration strength is good.
According to gas-insulated switchgear device of the present invention, because control cable is short, so cost is low, good work.
