The structural representation of the oil conservator that Fig. 2 provides for the utility model embodiment.
Among last Fig. 1-Fig. 2:
Embodiment
The utility model embodiment provides a kind of exhaust apparatus of oil conservator, has realized the hermetically sealed exhaust of oil conservator, and then has avoided outside air to the transformer influence in useful life.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to accompanying drawing 1-2, the structural representation of the exhaust apparatus of the oil conservator that Fig. 1 provides for the utility model embodiment; The structural representation of the oil conservator that Fig. 2 provides for the utility model embodiment.
The exhaust apparatus of the oil conservator that the utility model embodiment provides comprises: be used for the tube connector 11 that links to each other with the exhaust plug 21 of the cabinet 2 of oil conservator, this tube connector 11 has external screw thread; The non-return valve 13 that is connected with tube connector 11, this non-return valve 13 from cabinet 2 to extraneous conducting.
In the exhaust apparatus of the oil conservator that above-described embodiment provides, the external world refers to relatively and cabinet 2, is the external world of cabinet 2.To extraneous conducting, namely gas can only flow to the external world from cabinet 2 to non-return valve 13, and can not flow to cabinet 2 from the external world from cabinet 2.Exhaust plug 21 has internal thread usually, so need tube connector 11 to have external screw thread, to realize being connected of tube connector 11 and exhaust plug 21, the connector of non-return valve 13 also has internal thread usually simultaneously, thus being threaded of realization tube connector 11 and non-return valve 13.
