Abstract
Extracting apparatus is prevented under a kind of American Unit Substation pull-out fuse electriferous state, panel including American Unit Substation, panel is provided with pull-out fuse and on-load switch, the periphery of pull-out fuse is provided with the protective frame being fixed on panel, the side of protective frame is hinged with the protective plate covered on above pull-out fuse, and the opposite side of protective frame is provided with electromagnet.Prevent extracting apparatus from pull-out fuse can be prevented to be pulled out in the energized state under American Unit Substation pull-out fuse electriferous state of the present utility model, avoid high voltage personal injury and device damage；The steel plate deformed caused by the perforate of pull-out fuse can also be corrected simultaneously, prevents leakage of oil.
Description
Technical field
It the utility model is related to the pull-out fuse safety device field of American Unit Substation, specifically a kind of American-type box
Becoming under pull-out fuse electriferous state prevents extracting apparatus.
Background technology
The pull-out fuse of American Unit Substation is not allow to extract in the case of powered, if will in the energized state by mistake
Pull-out fuse, which is extracted, will cause high voltage personal injury and device damage, in routine work, for lacking experience and not
For the staff to go and find out what's going on, situation about by mistake extracting pull-out fuse is also to happen occasionally, directly exposed
Potential potential safety hazard be present in pull-out fuse；Formula fuse is additionally inserted into exposed to outer, can also caused by perforate steel plate
Deformation, the occurrence of causing oil leak.
The content of the invention
Technical problem to be solved in the utility model is the deficiency for overcoming above-mentioned prior art, there is provided a kind of structure letter
It is single, prevent extracting apparatus under the American Unit Substation pull-out fuse electriferous state to work well.
The utility model is realized with following technical scheme：Prevent under a kind of American Unit Substation pull-out fuse electriferous state
Only extracting apparatus, includes the panel of American Unit Substation, and the panel is provided with pull-out fuse and on-load switch, the plug-in type
The periphery of fuse is provided with the protective frame being fixed on panel, and the side of the protective frame, which is hinged with, to be covered on pull-out fuse
The protective plate of side, the opposite side of the protective frame are provided with the electromagnet for adhesive protective plate.
It is further：The electromagnet is powered by the low-pressure side of American Unit Substation.
The material of the protective frame is 2.0mm thickness galvanized steel plain sheets.
The material of the protective plate is 2.0mm thickness galvanized steel plain sheets.
The utility model has advantages below：Prevented under American Unit Substation pull-out fuse electriferous state of the present utility model
Extracting apparatus can prevent pull-out fuse to be pulled out in the energized state, avoid high voltage personal injury and equipment damage
It is bad；The steel plate deformed caused by the perforate of pull-out fuse can also be corrected simultaneously, prevents leakage of oil.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of the utility model protector；
In figure：1st, panel, 2, pull-out fuse, 3, on-load switch, 4, protective frame, 5, protective plate, 6, electromagnet.
Embodiment
Extracting apparatus, including U.S. are prevented under a kind of American Unit Substation pull-out fuse electriferous state as shown in Figure 1 to Figure 2
The panel 1 that formula case becomes, the panel 1 are provided with pull-out fuse 2 and on-load switch 3, the periphery of the pull-out fuse 2
Provided with the protective frame 4 being fixed on panel 1, the side of the protective frame 4 is hinged with the protection for covering on the top of pull-out fuse 2
Plate 5, the opposite side of the protective frame 4 are provided with the electromagnet 6 for adhesive protective plate 5.The electromagnet 6 is by the low of American Unit Substation
Press side power supply.The utility model is that protective frame is arranged on into the surrounding of pull-out fuse and is welded on American Unit Substation panel,
The height of protective frame is higher than the height of pull-out fuse, and protective frame is provided with protective plate, and protective plate is hinged on the one of protective frame
Side, and the protective plate can be provided with electromagnet by electromagnetic actuation on another side plate of protective frame, the power supply that electricity inhales iron is derived from U.S.
The low-pressure side that formula case becomes, after on-load switch, which closes a floodgate, to be powered, low-pressure side will be that electricity inhales iron power supply, and electromagnet can be by protective plate
Hold, realize the purpose that protective plate can not be opened under transformer belt electricity condition, protective plate blocks pull-out fuse
The inside, it furthermore achieved that the function that pull-out fuse can not be extracted under transformer belt electricity condition.Avoid because of maloperation
High voltage personal injury and device damage caused by pull-out fuse is extracted.It can also avoid because because of pull-out fuse simultaneously
Perforate caused by steel plate deformed, prevent leakage of oil.
Extracting apparatus is prevented under a kind of American Unit Substation pull-out fuse electriferous state as shown in Figure 1 to Figure 2, it is described anti-
The material for protecting frame 4 is 2.0mm thickness galvanized steel plain sheets.The material of the protective plate 5 is 2.0mm thickness galvanized steel plain sheets.It is of the present utility model
Protective frame and protective plate are 2.0mm thickness galvanized steel plain sheets, you can ensure protective plate and electromagnet directly effective adhesive, plate simultaneously
The steel plate of zinc can also improve the service life of protective frame and protective plate.
