Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
With reference to shown in Fig. 1, a kind of device preventing transformer insulation oil deterioration of the present utility model, comprise oil storage tank 1, insulating oil 3 is deposited in oil storage tank 1, also comprise in the first casing 4, second casing 5, first connector 6, second connector 10, first casing 4 being provided with in the first nitrogen bag 14, second casing 5 and be provided with the second nitrogen bag 15, be connected by the first connector 6 between first nitrogen bag 14 and oil storage tank 1, be connected by the second connector 10 between the second nitrogen bag 15 and oil storage tank 1.In the utility model, first, second this wording is only used to distinguish same class parts, device.Filling nitrogen in the first nitrogen bag 14 and the second nitrogen bag 15, the amount of nitrogen wants appropriate, can not too much or very little.Then the first nitrogen bag 14 is put into the first casing 4, second nitrogen bag 15 and put into the second casing 5, utilize the first connector 6 to be connected with oil storage tank 1 by first nitrogen bag 14, utilize the second connector 10 to be connected with oil storage tank 1 by second nitrogen bag 15.Nitrogen bag has certain stretching elasticity, and insulating oil 3 in oil storage tank 1 can be provided because of required expansion space of expanding with heat and contract with cold.When insulating oil 3 temperature rises, the nitrogen in oil storage tank 1 extrudes back in nitrogen bag by the insulating oil 3 of expansion; Otherwise when insulating oil 3 temperature declines, nitrogen can be backfilled to oil storage tank 1 in nitrogen bag, maintain poised state.When insulating oil 3 temperature rises or decline, extruding nitrogen can be utilized to produce expansion space, to guarantee the safe handling of transformer 2.
In the utility model, be provided with connector, have the first connector 6 and the second connector 10.First connector 6 as shown in Figure 1, comprise the first connector 6 and comprise the first valve 7, first adpting flange 8, first tube connector 9, first adpting flange 8 is arranged on the first casing 4, first tube connector 9 one end is arranged on the first adpting flange 8, and the other end of the first tube connector 9 is arranged on oil storage tank 1.Second connector 10 comprises the second valve 11, second adpting flange 12, second tube connector 13, second adpting flange 12 is arranged on the second casing 5, second tube connector 13 2 end is arranged on the second adpting flange 12, and the other end of the second tube connector 13 is arranged on oil storage tank 1.
During actual use, sometime in two nitrogen bags, can work by two nitrogen bags simultaneously, also only can have the work of a nitrogen bag.But as preferably, can select only there is the work of a nitrogen bag.Such as, the first nitrogen bag 14 works, and now, the nitrogen opened in the first valve 7, first nitrogen bag 14 enters oil storage tank 1 by the first tube connector 9.Like this, in oil storage tank, rubber bulb of the prior art is set with regard to unnecessary.And in oil storage tank, be filled with nitrogen, also just achieve the isolation with air.First nitrogen bag 14 is arranged in the first casing 4, and the first casing 4 can protect the first nitrogen bag 14 to avoid because external force etc. cause the first nitrogen bag 14 damaged, extends the useful life of the first nitrogen bag 14.If change the first nitrogen bag 14, opened by the second valve 11, then close the first valve 7, by the first adpting flange 8, be separated by the first nitrogen bag 14 with oil storage tank, the nitrogen bag then more renewed is as the first new nitrogen bag 14.Therefore, in Renewal process, the utility model can realize seamless replacing, finds that the first nitrogen bag 14 is damaged even if interim, also can Temporarily Closed first valve 7, opens the second valve 11, is worked by the second nitrogen bag 15.Then in due course between change the first nitrogen bag 14.Thus, the utility model perfection solves the problem of prior art.Do not need transformer power failure operation.Do not need to take oil storage tank apart.Can not because of taking apart in oil storage tank replacing rubber bulb process because air enters cause the rotten of insulating oil 3.
Visible, a kind of device preventing transformer insulation oil 3 deterioration of the present utility model, can maintain the balance to insulating oil in oil storage tank, and the utility model is changed conveniently, replacing construction is short, can realize changing at any time, do not need to open oil storage tank, do not need power failure operation.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection range of the present utility model.
