Abstract
The utility model relates to a tapping mechanism which is applied in a GIS (Gas Insulated Switchgear) and is connected with a cable. The mechanism comprises a transverse hole and a vertical hole which is vertical to the transverse hole; the transverse hole is connected with the vertical hole to form a mechanism which is shaped like the Chinese character ''tu'' (concave). Compared with the prior art, the utility model has the advantages that the tapping mechanism can decrease the occupied underground space, has simple mechanism and is convenient to construct, etc.
Description
Technical field
The utility model relates to electric power transmission & distribution field, especially relates to the perforate mechanism that a kind of GIS of being applied to is connected with cable.
Background technology
At electric power transmission & distribution field GIS (Gas insulated switchgear; The sulphur hexafluoride gas insulated metal enclosed swit chgear) in the cable interconnection technique; Be generally the bending radius that satisfies cable and the making of cable termination, need stop enough spaces to the cable floor floor height of GIS below.
As shown in Figure 1.Conventional GIS below floor bore size is only by offering greater than GIS terminal projection size.Should be from cable floor ground to GIS cable termination cylindrical shell bottom surface this moment: Cable Bending Radius a+ tail pipe straightway b+ (flange thickness outside cable termination tail pipe height+GIS cable termination) c.The cable floor floor height should be: above-mentioned height-cable termination cylindrical shell bottom surface is from the height d of GIS room floor.
As shown in Figures 2 and 3, traditional floor perforate is a slot, the very inconvenience of installation of such mechanism pair and the liftoff nearer GIS of cable termination.
In present urban construction, the underground space is in short supply day by day, the increase day by day of construction cost.How to adopt technological means that prior art is improved, dwindle the cable floor height as far as possible, thereby reduce engineering construction cost, become the technical problem that those skilled in the art press for solution.
The utility model content
The purpose of the utility model is exactly to provide a kind of can the minimizing take the underground space for the defective that overcomes above-mentioned prior art existence, and mechanism is simple, and construction is applied to the perforate mechanism that GIS is connected with cable easily.
The purpose of the utility model can realize through following technical scheme: the perforate mechanism that a kind of GIS of being applied to is connected with cable; It is characterized in that; This mechanism comprises a cross-drilled hole and one and the perpendicular vertical core of described cross-drilled hole, and cross-drilled hole and vertical core are connected to form a convex shape mechanism.
Described cross-drilled hole is a slot.
Described vertical core is a slot.
Compared with prior art, the utlity model has to reduce and take the underground space, mechanism is simple, the advantage easily of constructing.
Description of drawings
Fig. 1 is a GIS cable bindiny mechanism sketch map;
Fig. 2 is the GIS sectional drawing;
Fig. 3 is a Traditional GIS basis perforate structural scheme of mechanism;
Fig. 4 is the GIS basis perforate structural scheme of mechanism of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
Perforate mechanism as shown in Figure 4, that a kind of GIS of being applied to is connected with cable, this mechanism comprise the vertical core 1 that a cross-drilled hole 2 and and said cross-drilled hole 2 are vertical, and cross-drilled hole 2 is connected to form a convex shape mechanism with vertical core 1.Cross-drilled hole 2 is a slot.Vertical core 1 is a slot.Basic perforate mechanism through with existing GIS cable termination below is expanded into convex shape mechanism; Make when adopting this kind mechanism; Can cable termination be raised to the construction of GIS aspect, descending after having constructed moves to GIS housing below again, up inserts in the GIS housing then; This method can be saved epoxy equally and separate this height of cover, thereby significantly reduces the cable floor height.This scheme should be from cable floor ground to GIS cable termination cylindrical shell bottom surface: the final radius of turn of cable+cable length of straigh line+cable termination tail pipe height+(epoxy is separated cover height+epoxy and separated cover metal joint height).The cable floor floor height should be: above-mentioned height-cable termination cylindrical shell bottom surface height overhead.
Liftoff very near GIS is an example with cable termination, and this scheme is to cable floor requirement for height such as following table 1 and table 2:
Table 1 220kV cable floor high request
| 220kV cable floor high request | |
| Below the 1600mm2 (wet type) | 4600mm |
| Below the 2500mm2 (wet type) | 5000mm |
| Below the 1600mm2 (dry type) | 3700mm |
| Below the 2500mm2 (dry type) | 4000mm |
Table 2 110kV cable floor high request
| 110kV cable floor high request | |
| Below the 1200mm2 (wet type) | 4100mm |
| Below the 1200mm2 (dry type) | 3800mm |
The utility model is owing to adopted above-mentioned bindiny mechanism; With being arranged in the tunnel connecting portion that joint portion on the cable shaft outer wall is arranged on the outer tunnel, station in the prior art, utilize the space of tunnel connecting portion to hold the last bending section of cable, the outlet cable is located in the cable shaft with vertical state basically; Thereby reduced the floor height of cable floor greatly; Practiced thrift the underground space, it is few to have the underground space of taking, and mechanism is simple; The beneficial effect easily of constructing goes for being connected of the liftoff very near GIS of cable termination and cable.
