Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The exploded view of the dry transformer outer case construction that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of casing frame.
Embodiment
Core of the present utility model is to provide a kind of dry transformer outer case construction, improves the anti-seismic performance of dry-type transformer case, ensures the safe operation of dry-type transformer in strong motion environment.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Incorporated by reference to Fig. 1, the exploded view of the dry transformer outer case construction that Fig. 1 provides for the utility model.
Dry transformer outer case construction provided by the utility model, comprises casing frame 1, sheet material 2, connector and for the installing hole of installation connecting element.
The dry transformer outer case construction that the utility model embodiment provides, the integrated casing framework 1 that employing is metallic atom lattice structure is the skeleton of structure as a whole, sheet material 2 is fixed on to the body structure that forms sealing on casing frame 1 by connector, dry transformer outer case construction in strong motion environment, because the structure of casing frame 1 has fabulous power transmission, can be subject under the condition of the different active forces of all directions, make stressedly in integral body, to disperse preferably, be difficult for causing stress to concentrate, thereby improved the anti-seismic performance of dry transformer outer case construction, ensured the safe operation of dry-type transformer in strong motion environment.
In a specific embodiment of the present utility model, the connector of dry transformer outer case construction comprises screw bolt and nut.
Cooperation by bolt and nut is fixed on sheet material 2 on casing frame 1, the whole body structure that forms, when bolt is installed, the head of bolt is arranged to the outer surface of body structure, so not only be convenient to the maintenance of equipment, and under strong motion environment, if bolt occurs to become flexible and comes off from sheet material 2, can not fall the inside at body structure yet, the phenomenon of having avoided loosening bolt to drop and cause transformer to open circuit and burn in dry-type transformer, when having improved whole anti-seismic performance, improved again whole fail safe like this.
In order further to guarantee the fixing stability of bolt in strong motion environment, nut is selected U-shaped elastic nut, and is fastened on casing frame.
Incorporated by reference to Fig. 2, the structural representation that Fig. 2 is casing frame.
