Abstract
The utility model relates to a grounding structure of a transformer core and a clamping piece. The grounding structure comprises a cover plate, a mounting barrel, a flange and a wiring board, wherein the mounting barrel and the flange are fixed on an outer shell of a transformer by welding; the flange is positioned in the mounting barrel; a first sealing ring is arranged between the cover plate and the mounting barrel that are connected through a bolt; a second sealing ring is arranged between the flange and the wiring board that are connected through a bolt; a core grounding rod and a clamping piece grounding rod are cast and directly fixed on the wiring board; and two ends of the core grounding rod are connected with a grounding sheet on the core and a grounding point in the mounting barrel respectively through a core grounding line. The grounding structure of the transformer core and the clamping piece is simple, convenient to manufacture, firm in sealing, not easy to damage and low in cost, and can meet user requirements.
Description
Technical field
The utility model relates to the ground structure of a kind of transformer core and folder.
Background technology
Traditional transformer core, folder ground connection are after drawing from top cover by two small casings, to cause the transformer lower position by copper bar or cable again.Small casing is subjected to extraneous factor to influence easy damage in the long-distance transportation process, and the installation sealing surface can not get ensureing that the phenomenon that oil impregnate, leakage of oil occur is more frequent; Adopt conventional method in addition, the time-consuming material that takes.
The utility model content
The utility model at traditional transformer core, folder ground connection be draw from top cover by two small casings after, cause the above-mentioned deficiency that the transformer lower position produces by copper bar or cable again, the ground structure of a kind of transformer core and folder is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the ground structure of a kind of transformer core and folder comprises cover plate, seat raises, flange and terminal block, described rising seat and flange are fixed by welding on the shell of transformer, described flange is positioned at the seat that raises, described cover plate and raise and to be provided with first sealing ring between the seat and to connect by bolt, be provided with second sealing ring between described flange and the terminal block and connect by bolt, iron core grounding post and folder earthing rod directly are fixed on the terminal block by pouring into a mould, the two ends of described iron core grounding post link to each other by an earth point in the ground strip on iron core grounding line and the iron core and the seat that raises respectively, and the two ends of described folder earthing rod link to each other with a earth point and a rising interior earth point on the folder by the folder earth connection respectively.
The beneficial effects of the utility model are: the ground structure of the utility model transformer core and folder simple in structure, easy to make, sealing is firm, not fragile, cost is low, be a kind of iron core, folder ground structure that can satisfy customer requirements.

Description of drawings
Fig. 1 is the structural representation of the ground structure of the utility model transformer core and folder.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is the structural representation of the ground structure of the utility model transformer core and folder.As shown in Figure 1, the ground structure of described transformer core and folder comprises cover plate 1, seat 2, flange 4 and terminal block 6 raise.Described rising seat 2 and flange 4 are fixed by welding on the shell of transformer, and described flange 4 is positioned at the seat 2 that raises.Described cover plate 1 and raise and to be provided with first sealing ring 8 between the seat 2 and to connect by bolt.Be provided with second sealing ring 5 between described flange 4 and the terminal block 6 and connect by bolt.Described first sealing ring 8 and second sealing ring 5 the effect that can play sealing is set, being provided with of described second sealing ring 8 can prevent that leakage of oil or oil impregnate from appearring in terminal block 6 places, being provided with of described first sealing ring 8 can be when leakage of oil or oil impregnate appear in terminal block 6 places, prevent that leakage of oil or oil impregnate from appearring in cover plate 1 place, prevent that promptly leakage of oil or oil impregnate from appearring in ground structure of the present utility model.Iron core grounding post 3 and folder earthing rod 7 directly are fixed on the terminal block 6 by pouring into a mould, the two ends of described iron core grounding post 3 link to each other by earth points in the ground strip on iron core grounding line and the iron core and the seat 2 that raises respectively, and the two ends of described folder earthing rod 7 link to each other with a earth point and rising 2 interior earth point on the folder by the folder earth connection respectively.Second sealing ring 5 between terminal block 6 and flange 4 goes wrong, when causing terminal block 6 places leakage of oil or oil impregnate to occur, the setting of first sealing ring 8 can be used as the second road barrier after the first road barrier is second sealing ring 5 between flange 4 and the terminal block 6, guarantee that it is oil-proof, play the dual-seal effect.The inside and outside two-layer hermetically-sealed construction that first sealing ring and second sealing ring form in the ground structure of the utility model transformer core and folder makes it be not easy to occur damage, oil leakage phenomenon.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
