The cover body is a rectangular box body; an inclined plane is formed on the upper part of the front of the rectangular box body, and is provided with a round through hole; the round through hole is matched with a pull port of a GIS shell; the inclined plane is connected with the pull port; an outgoing line hole is formed on the rectangular box body; and a plate on the back of the rectangular box body has a detachable connection structure. The cover body has the characteristics of reasonable structure, convenience for leading out cables, and neat and compact layout.
Description
Technical field
The utility model relates to a kind of altogether outgoing line device technical field of case GIS combined electrical apparatus, specifically a kind of altogether case GIS combined electrical apparatus current transformer outlet cover body.
Background technology
Altogether after the installation of case GIS combined electrical apparatus, need to lay secondary cable, the leading-out terminal that is the current transformer in the combined electrical apparatus is connected with the linear quadratic control cabinet by circuit, usually protect for the leading-out terminal place to current transformer, at this place an outlet cover body can be set, also claim the CT cover, cable is connected with the linear quadratic control cabinet after passing the CT cover, for cable being protected the sheathed metal hose in this section cable outside between linear quadratic control cabinet and CT cover.Traditional CT cover is cylindrical housings, and a side is connected the opposite side outgoing cable with the mouth that pulls out of combined electrical apparatus housing, the CT cover of this structure, when outgoing cable, the cabling of cable is difficult to smooth vertical and horizontal, thereby increase the length that metal hose is used in the outside, also cause layout messy.
Summary of the invention
The utility model provides a kind of rational in infrastructure in order to overcome defects, makes things convenient for outgoing cable, the clean and tidy compact common case GIS combined electrical apparatus current transformer outlet cover body of layout.
The technical solution adopted in the utility model is: a kind of altogether case GIS combined electrical apparatus current transformer outlet cover body, described cover body is the rectangle box body, front upper at rectangle shape box body is provided with an inclined plane, be provided with manhole on this inclined plane, pulling out of this manhole and combined electrical apparatus housing is mouthful suitable, and described inclined plane is connected with the described mouth that pulls out, and is provided with wire hole at the rectangle box body, and the plate at rectangle box body rear portion is set to the structure that removably connects.
Wire hole described in the utility model can be arranged on the lower front of rectangle box body.
Wire hole described in the utility model can be arranged on the bottom of rectangle box body.
Wire hole described in the utility model can also be arranged on the sidepiece of rectangle box body.
The utility model advances the rectangularity box body with traditional cylindrical outlet hood structural reform, and be provided with an inclined plane with manhole in the front upper of rectangle box body and be used for mouthful being connected with pulling out of combined electrical apparatus housing, because pulling out mouth normally is obliquely installed, so the inclined plane that arranges on the cover body can better mouthful be connected with pulling out, also make things convenient for current transformer from pulling out a mouthful outlet, arrange on the cover body wire hole make things convenient for cable outlet and with the connection by metal hose of wire hole arranged outside, passing metal hose after cable is drawn is connected with the linear quadratic control cabinet, can make like this cable routing compact, neatly, but also can shorten the length of metal hose, save material; It is rectangle box body lower front that wire hole of the present utility model can be arranged on cover body, also can be arranged on the bottom of box body, can also be arranged on the sidepiece of box body, structure and outlet according to combined electrical apparatus are selected, increased the outlet method of current transformer, made outlet method more flexible, convenient simple and direct.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is that the utility model uses state reference map.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, cover body of the present utility model is rectangle box body 2, front upper at rectangle shape box body 2 is provided with an inclined plane 1, namely the plate face of these box body 2 front portions is comprised of the inclined plane 1 on top and the riser face of bottom, two sidepieces of box body 2 are up-narrow and down-wide shape, see Fig. 1, be provided with manhole on the described inclined plane 1, see Fig. 2, pulling out of this manhole and combined electrical apparatus housing 6 is mouthfuls 5 suitable, it is corresponding to be that the size of through hole and housing 6 pull out mouthfuls 5 bore, and described inclined plane 1 is connected with the described mouth 5 that pulls out, and usually in the junction of pulling out mouth 5 and box body 2 waterproof sealing gasket is set.Be provided with wire hole 8 at rectangle box body 2, wire hole 8 outsides are connected with metal hose 3, plate at rectangle box body 2 rear portions is set to detachable syndeton, in the present embodiment, the plate at box body 2 rear portions is square cover body formula, and being buckled in the outside of box body 2 sidepieces, the junction of the plate at box body 2 rear portions and box body 2 sidepieces also is provided with waterproof sealing gasket.Wire hole 8 in the present embodiment is arranged on the lower front of rectangle box body 2, namely on the riser face of 1 below, inclined plane.Wire hole 8 of the present utility model can also be arranged on the bottom of box body 2 or the sidepiece of box body 2, selects according to structure and the wiring needs of combined electrical apparatus.
Altogether after the installation of case GIS combined electrical apparatus; the cable that picks out on the connection terminal disk of current transformer passes from the mouth 5 that pulls out of housing 6; entering the outlet cover body by the manhole on the inclined plane 1 is that the CT cover is inner; then cable is connected with the linear quadratic control cabinet from the metal hose 3 that the wire hole 8 of CT cover passed and passed wire hole 8 outsides; also can between metal hose 3 and linear quadratic control cabinet, cable tray 4 be set; cable passes from the wire hole 8 of CT cover and is connected with the linear quadratic control cabinet after entering cable tray 4 by metal hose 3 again; see Fig. 3; metal hose 3 can be to protecting from the cable between CT cover and the cable tray; cable tray 4 is set can be to the current transformer above the GIS body; mechanism; the cable of density monitor etc. is fixed and protects; make cable laying in the cable tray of sealing, avoid outside factor to cause the damage of cable.The utility model is provided with the square CT cover with inclined plane 1, can better with pull out mouthfuls 5 and be connected, make things convenient for the current transformer outlet, cable is drawn from wire hole 8 and is then passed metal hose 3 and be connected with the linear quadratic control cabinet, can make cable routing compact, clean and tidy, can also shorten the length of metal hose 3, save material; Wire hole 8 of the present utility model can be as being arranged on box body 2 lower front in the present embodiment, also can be arranged on the bottom of box body 2, can also be arranged on the sidepiece of box body 2, structure and outlet according to combined electrical apparatus are selected, increased the outlet method of current transformer, made outlet method more flexible, convenient simple and direct.
The utlity model has rational in infrastructurely, make things convenient for outgoing cable, the clean and tidy compact characteristics of layout.
