Abstract
The utility model discloses an isolating hood comprising a unit hood body that is formed by press-injection of insulating materials, and composition of a front side panel, a rear side panel, a left side panel, a right side panel and a top panel; the rear part of the top panel is higher than the front part, and the top panel is provided with a plurality of external vent holes; the bottom end of the rear panel is provided with an opening; the upper parts of the rear ends of the left and right side panels are respectively provided with a rear mounting hole protruding behind the rear side panel, and the two rear mounting holes are coaxially arranged; and the front parts of the tops of the left and right side panels are respectively provided with an upper mounting holes, the two upper mounting holes are coaxially arranged and higher than the corresponding parts of the top panel, and the lower parts of the left and right side panels are respectively provided with a connecting hole. Compared with the prior art, the isolating hood can effectively isolate arc light, and the insulating property is promoted; in addition, the isolating hood has the advantages of light weight and convenience in use.
Description
Technical field
The present invention relates to electric power system equipment for power transmission and distribution manufacturing technology field, in particular for the alternate device of isolated insulation relatively that reaches of sulfur hexafluoride gas-insulating metal switch equipment.
Background technology
At present, along with sulfur hexafluoride gas-insulating metal switch equipment is little and used in a large number with its volume, the size of the on-load switch in the high-tension switch cabinet has determined the size of whole cabinet to a great extent, satisfy insulation simultaneously in order to obtain smaller size, by increasing separator, alternate isolation distance is dwindled, and the means of this separator are widely used.Existing separator adopts insulating barrier or heat-shrinkable T bush to constitute more, and weight ratio is bigger, is not easy to install, and consistency is poor, and dielectric strength is lower, and the basic structure of surrounding entirely that adopts, and is unfavorable for heat radiation.
Summary of the invention
Problem to be solved in the utility model provides a kind of cage, and it is poor that this cage can solve existing isolating device insulation property, and weight is big, awkward problem.
In order to address the above problem, the employing of this cage following technical scheme: this cage comprises and being formed by the insulating material pressure injection, by front panel, the rear side panel, Left-Hand Panel, the unit cover body of right panel and the compound formation of top panel, the rear part of described top panel is higher than the place ahead part, on described panel, be provided with a plurality of air-vents, described rear side panel bottom end is provided with opening, the top of the rear end of described Left-Hand Panel and described right panel is respectively equipped with a back installing hole that protrudes in after the described rear side panel, the coaxial setting of installing hole after these two; The front portion of described Left-Hand Panel and described right panel Xiang Duan is respectively equipped with one and goes up installing hole, go up the coaxial setting of installing hole for these two, go up installing hole for these two and be higher than described top panel, be equipped with connecting hole in the bottom of described Left-Hand Panel and described right panel in the part between the installing hole on these two.
In the technique scheme, can be combined into the cage that a threephase switch is used by three described unit cover bodies, these three unit cover bodies are arranged side by side successively, and adjacent two described unit cover bodies interconnect by the band in the described connecting hole that is installed on these two unit cover bodies.
Owing to adopted above-mentioned design, the present invention with the beneficial effect that the heat-shrink tube of prior art is compared is: good insulation preformance, in light weight, and easy to install.Be used in the sulphur hexafluoride insulating gas medium and can effectively isolate arc light, reinforced insulation makes sulphur hexafluoride can form effective convection current in the arc extinguishing process, helps heat radiation and arc extinguishing.
Description of drawings
Below in conjunction with drawings and Examples the design is further specified.
Fig. 1 be the utility model embodiment 1 structural representation;
Fig. 2 is the lateral plan of the utility model embodiment 1;
Fig. 3 is the structural representation of the utility model embodiment 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1, cage shown in Figure 2 comprise and being formed by the insulating material pressure injection, by front panel 1, rear side panel 3, Left-Hand Panel 4, the unit cover body of right panel 2 and top panel 5 compound formations, the rear part of top panel 5 is higher than the place ahead part, on top panel 5, be provided with a plurality of air-vents 9, the bottom of rear side panel 3 is provided with opening, and the top of the rear end of Left-Hand Panel 4 and right panel 2 is respectively equipped with a back installing hole 6 that protrudes in after the rear side panel 3, the coaxial setting of installing hole after these two; The front portion on Left-Hand Panel 4 and right panel 2 tops is respectively equipped with one and goes up installing hole 7, go up the coaxial setting of installing hole for these two, go up installing hole for these two and be higher than top panel 5, be equipped with connecting hole 8 in the bottom of Left-Hand Panel 4 and right panel 2 in the part between the installing hole on these two.
Shown in Figure 3, this cage in use, generally be to be combined into the cage that a threephase switch is used by three described unit cover bodies, these three unit cover bodies are arranged side by side successively, adjacent two unit cover bodies interconnect by the band 10 in the connecting hole 8 that is installed on these two unit cover bodies, the installing hole 6 of each unit cover body is installed on the same installation shaft, and the installing hole 7 of each unit cover body is installed on the same installation shaft.
