Abstract
The utility model relates to a breather for a transformer. The breather is arranged between electrical equipment and a transformer oil tank, and comprises a cover cap, an upper cover plate, a lower cover plate, a glass cover and silica gel, wherein the cover cap is fixed on the upper cover plate by a bolt A; the upper cover plate and the lower cover plate are respectively arranged at the upper end and the lower end of the glass cover; and the silica gel is filled in the glass cover. Compared with the prior art, the breather for the transformer has the advantages of being simple in structure, convenient to maintain, low in cost, convenient and fast to use, etc.
Description
Technical field
The utility model relates to a kind of respirator, especially relates to a kind of transformer and uses respirator.
Background technology
Transformer respirator (being dehydrating breather or air-breather again) is connected through pipeline on the conservator of transformer, and drier is equipped with in its inside, like silica gel; Be used for the airborne moisture of adsorption filtration discrepancy transformer conservator; Slow down making moist and oxidation of transformer insulation oil, to keep the quality of transformer insulation oil, the quality of respirator performance; The length in useful life will directly influence the electric equipment reliability of operation.
At present; Respiratory organ structure on the market is complicated, cost an arm and a leg, the inconvenience maintenance; A kind of oily respirator is disclosed like utility application 200520048291.8, comprise expiration assembly, getter assembly and two ends respectively with the interior cover of expiration assembly, getter assembly socket and hollow.Wherein, interior cover side is provided with and is used for the connector that is communicated with oil pipe; The expiration assembly comprises first trunnion that is communicated with interior cover, be positioned at the ball-type spool of the first trunnion inner chamber and have pore and cover the upper end cover on first trunnion; Wherein the first trunnion inner chamber comprise first inner chamber that holds spool, be communicated with first inner chamber, interior cover and diameter than little second inner chamber of valve core diameter and first interface ramp between first inner chamber and second inner chamber; Getter assembly comprises aux. venturi, the ball-type spool that is positioned at the aux. venturi inner chamber that is communicated with interior cover and has pore and the bottom end cover of covering aux. venturi; Wherein the aux. venturi inner chamber comprise the 3rd inner chamber that holds spool, be communicated with the 3rd inner chamber, interior cover and diameter than little the 4th inner chamber of valve core diameter and be positioned at the 3rd inner chamber and the 4th inner chamber between second interface ramp.This kind respirator maintenance difficult, and cost is higher, is not suitable for the extensive application in network system.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of transformer simple in structure, easy to maintenance, that cost is low, easy to use to use respirator for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
A kind of transformer is used respirator; This respirator is arranged between electric equipment and oil tank of transformer; It is characterized in that described respirator comprises cover cap, upper cover plate, lower cover, cloche and silica gel, described cover cap is fixed on the upper cover plate through bolt A; Described upper cover plate, lower cover are separately positioned on the top and bottom of cloche, and described silica gel is filled in the cloche.
The cover cap of being told connects electric equipment through ring flange, and the lower end of described cloche connects oil tank of transformer.
Be equipped with rubber blanket between the cover cap of being told, upper cover plate, cloche, the lower cover.
Be respectively arranged with air inlet and gas outlet in the middle of described upper cover plate, the lower cover, be fixed with screen pack through bolt B on described air inlet and the gas outlet.
Compared with prior art, the utlity model has advantage simple in structure, easy to maintenance, that cost is low, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is cover cap, and 2 is upper cover plate, and 3 is lower cover, and 4 is cloche, and 5 is silica gel, and 6 is bolt A, and 7 is ring flange, and 8 is the transformer mailbox, and 9 is rubber blanket, 10 bolt B, and 11 is screen pack.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1; A kind of transformer is arranged on 8 of electric equipment and oil tank of transformer with respirator, and this respirator comprises cover cap 1, upper cover plate 2, lower cover 3, cloche 4 and silica gel 5, and cover cap 1 is fixed on the upper cover plate 2 and through ring flange 7 through bolt A6 and connects electric equipments; Upper cover plate 2, lower cover 3 are separately positioned on the top and bottom of cloche 4; The lower end of cloche 4 connects oil tank of transformer 8, fills by silica gel 5 in the cloche 4, is used to absorb airborne moisture and impurity.Between cover cap 1, upper cover plate 2, cloche 4, lower cover 3, be equipped with rubber blanket in addition; In the middle of upper cover plate 2, lower cover 3, be respectively arranged with air inlet and gas outlet; Be fixed with screen pack 11 through bolt B 10 on air inlet and the gas outlet, prevent contamination by dust oil and anti-oil pollution air.
When oil tank of transformer 8 internal pressures were elevated to certain pressure, gas was discharged in the external environment condition through gas outlet, air inlet successively, thus release pressure; When oil tank of transformer 8 internal pressures were reduced to certain pressure, gas was from entering into oil tank of transformer 8 through air inlet, gas outlet successively, thereby it is stable to keep-up pressure.
