Description
Technical field:
The utility model belongs to high voltage equipment field, relates to a kind of GIS(Cubicle Gas-Insulated Switchgear) distribution structure.
Background technology:
Along with the growth at full speed of national economy, domestic a large amount of extra-high-voltage alternating current transformer stations and DC converter station are built and are put into operation successively, still have a large amount of ultra-high voltage transformer stations, current conversion station in planning construction.In extra-high-voltage alternating current transformer station and DC converter station, power distribution equipment is arranged comparatively complicated, will inevitably produce 1000kV GIS pipeline bus and need pass through this problem of road.For 1000kV GIS, if passing through in the employing routinely of road place, pipeline bus passes through scheme (at the localized raised GIS of road place pipeline bus, reducing again height after leap road), its disadvantage has comparatively adverse influence to installation and repairing exactly.When crane lifting GIS main equipment, have arm, suspension hook and be lifted the possibility that thing and the GIS pipeline bus raised are collided, once meet accident, consequence is very serious.Meanwhile, the scheme of passing through is on the ground very unfavorable to aseismic design, and equipment seismic Calculation is difficult to pass through.
Utility model content:
The purpose of this utility model is to provide a kind of pipeline bus to pass through the distribution structure of road, leader cable ditch is set between GIS main equipment and road, GIS pipeline bus penetrates subterranean tunnel between leader cable ditch and road, the auxiliary systems such as illumination, draining, ventilation are set, can meet the needs of Practical Project in tunnel.
For achieving the above object, the utility model is to take following technical scheme to be achieved:
Pipeline bus passes through a distribution structure for road, comprises pipeline bus, road, tunnel cover plate and grid plate; Road below is provided with tunnel; Tunnel upper is provided with tunnel cover plate, and cover plate both sides, tunnel are provided with withdraw-type grid plate; Grid plate arranged outside has leader cable ditch; Pipeline bus penetrates tunnel from the grid plate of tunnel cover plate one side, passes tunnel from the grid plate of tunnel cover plate opposite side.
The utility model further improves and is: leader cable ditch outside is furnished with GIS main equipment.
The utility model further improves and is: tunnel cover plate is made up of some detachable cover plates.
The utility model further improves and is: the structure that pipeline bus adopts some joint expansion joints to connect in tunnel.
The utility model further improves and is: in tunnel, be provided with illuminator, drainage system and ventilating system.
The utility model further improves and is: the part that pipeline bus runs through tunnel is U-shaped.
The utility model further improves and is: described pipeline bus is GIS lateral bus, and one side connects the GIS main equipment that is arranged in leader cable ditch outside, and opposite side connects GIS main pipeline bus.
With respect to prior art, the utility model has the advantages that:
1, make the GIS pipeline bus can be easily from Underground Crossing road, do not affect GIS main equipment lifting maintenance.
2, comparatively favourable to GIS antidetonation, guarantee fail safe.
3, tunnel top cover plate be set to piecemeal can withdraw-type, facilitate installation and repairing.
4, GIS pipeline bus adopts the devices such as expansion joint in tunnel, takes pipeline bus apart several parts shorter into length; Penetrate and pass tunnel place at pipeline bus grid plate is set, if desired grid plate is removed, branch bar segmentation in tunnel is hung out, be conducive to operating maintenance simultaneously.
5, the auxiliary systems such as illumination, draining, ventilation are set in tunnel, guarantee reliable.
Accompanying drawing explanation:
Fig. 1 is the utility model power distribution equipment floor map;
Fig. 2 is the utility model power distribution equipment sectional schematic diagram.
In figure: 1, GIS main equipment; 2, GIS main pipeline bus; 3, GIS lateral bus; 4, GIS expansion joint; 5, disc insulator; 6, leader cable ditch; 7, road; 8, tunnel; 9, cover plate; 10, grid plate; 11, entrance.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 and Fig. 2, a kind of pipeline bus of the utility model passes through the distribution structure of road, between GIS main equipment 1 and road 7, leader cable ditch 6 is set, GIS pipeline bus penetrates subterranean tunnel 8 between leader cable ditch 6 and road 7, the interior auxiliary systems such as illumination, draining, ventilation that arrange in tunnel 8.From Fig. 1 and Fig. 2, can find out, this kind of design arrangement mode arranges leader cable ditch 6 between GIS main equipment 1 and road 7, and GIS pipeline bus penetrates subterranean tunnel between leader cable ditch 6 and road 7; Tunnel cover plate 9 is removable is divided into some, and piecemeal is removed under special circumstances; GIS pipeline bus, at the interior employing in tunnel 8 GIS expansion joint 4, is taken pipeline bus apart several parts shorter into length, and what coordinate that pipeline bus enters to be located in can withdraw-type grid plate 10, can realize easily installation and repairing.While adopting this scheme, GIS pipeline bus can be easily from Underground Crossing road 7, does not affect GIS main equipment lifting maintenance; Comparatively favourable to GIS antidetonation, guarantee fail safe; Installation and repairing more for convenience.The more conventional pipeline bus of this scheme on the ground scheme of passing through has had very large optimization.
Refer to shown in Fig. 1, in specific embodiment of the utility model, the GIS main equipment 1 of road 7 one sides connects GIS main pipeline bus 2 and GIS lateral bus 3, GIS lateral bus 3 penetrates subterranean tunnel 8 from the entrance 11 of grid plate 10, GIS lateral bus 3 is at the interior employing in tunnel 8 GIS expansion joint 4, take GIS lateral bus 3 apart several parts shorter into length, convenient maintenance; Between GIS expansion joint 4, connect by disc insulator 5.The part that GIS lateral bus 3 runs through road 7 is U-shaped, and GIS lateral bus 3 runs through the GIS main pipeline bus of the rear connection opposite side of road 7.
Can draw by above-mentioned analysis, between 1000kV GIS main equipment 1 and road 7, leader cable ditch 6 is set, road 7 belows arrange subterranean tunnel 8, GIS pipeline bus has the installation and repairing of convenience, improves equipment anti-seismic performance, guarantees the features such as safe and reliable to operation from the distribution structure that penetrates subterranean tunnel 8 between leader cable ditch 6 and road 7 and pass through road, can application preferably in engineering; And for passing through road scheme, 1000kV GIS pipeline bus provide a new optimization to solve structure.
