Description
Technical field
The utility model relates to technical field of transformer manufacturing, particularly relates to a kind of plate-type oil box structure for oil-filled transformer.
Background technology
The board-like fuel tank that now general oil-filled transformer is used, is equipped with oil level indicator pressure relief valve at lid section.Its effect be the oil level of transformer oil in fuel tank in order to detect transformer simultaneously when decompositing gas in oil tank of transformer, when causing air pressure to increase, the pressure in fuel tank can be discharged.
The board-like Oiltank structure of existing transformer mainly observes oil level and release pressure by oil level indicator pressure relief valve, and current this structure, because the purchase cost of oil level indicator is higher, causes cost when producing to float, falls in profitability.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of plate-type oil box structure for oil-filled transformer, directly can observe oil sample, and structural design is simple, and easy to operate, cost is comparatively cheap.
The technical scheme realizing above-mentioned purpose is: a kind of plate-type oil box structure for oil-filled transformer, comprise oil tank body and be arranged on the some fin on the sidewall of oil tank body, described plate-type oil box structure also comprises at least one arc transparent reinforced glasses pipe, each arc transparent reinforced glasses pipe is all vertically arranged, each described arc transparent reinforced glasses Guan Jun is between adjacent two described fin, and the two ends of each described arc transparent reinforced glasses pipe are connected with the flange on the sidewall being welded on described oil tank body by sealing ring correspondingly, each described arc transparent reinforced glasses pipe also arranges a pressure release glass tube projected upwards, this pressure release glass tube and corresponding described arc transparent reinforced glasses pipe mutually through and one-body molded, the top of the tube wall of each described pressure release glass tube is provided with two relief holes, each described pressure release glass tube is arranged one for covering the glass cap of described two relief holes.
Above-mentioned a kind of plate-type oil box structure for oil-filled transformer, wherein, described two relief holes are symmetrical arranged on the top of the tube wall of corresponding pressure release glass tube.
Plate-type oil box structure for oil-filled transformer of the present utility model, beneficial effect is compared with prior art: in the middle of the fin of original board-like fuel tank, increase at least one transparent reinforced glasses pipe to replace the effect of original oil level indicator pressure relief valve, directly can observe oil sample, this kind of structural design is simple, easy to operate, cost is comparatively cheap.Only need increase at least one arc transparent glass tube in the space between fin and oil tank body, the effect of original oil level indicator pressure relief valve can be played, simultaneously because add these arc transparent glass tubes, contribute to the thermal diffusivity improving transformer.

Embodiment
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, its embodiment is described in detail:
Refer to Fig. 1 and Fig. 2, most preferred embodiment of the present utility model, a kind of plate-type oil box structure for oil-filled transformer, comprise oil tank body 1, be arranged on some fin 2 on the sidewall of oil tank body 1 and at least one arc transparent reinforced glasses pipe 3, each arc transparent reinforced glasses pipe 3 is all vertically arranged, each arc transparent reinforced glasses pipe 3 is all between adjacent two fin 2, and the two ends of each arc transparent reinforced glasses pipe 3 are connected with the flange 5 on the sidewall being welded on oil tank body 1 by sealing ring 4 correspondingly.
Refer to Fig. 3 to Fig. 5 again, each arc transparent reinforced glasses pipe 3 is also arranged a pressure release glass tube 6 projected upwards, this pressure release glass tube 6 is mutually through and one-body molded with corresponding arc transparent reinforced glasses pipe 3, the top of the tube wall of each pressure release glass tube 6 is provided with two relief holes 61, each pressure release glass tube 61 is arranged one for covering the glass cap 62 of two relief holes 61.Two relief holes 61 are symmetrical arranged on the top of the tube wall of corresponding pressure release glass tube 6.
Plate-type oil box structure of the present utility model, arc transparent glass tube 3 carrys out the effect of alternative former oil level indicator pressure relief valve and oil sample valve, during normal use, has transformer oil to flow through, be as good as with common fin in this arc transparent glass tube 3.Owing to have employed transparent material, so we can observe directly transformer oil condition.According to the principle that pressure inside and outside physics is equal, when the transformer oil in fuel tank reduces, when air pressure increases, the oil pressure in arc transparent glass tube 3 also can decrease, its oil level should be equal with the oil level in fuel tank, so just easy to doly can observe the situation of oil level in oil tank of transformer.Meanwhile, when the gas in fuel tank is too much, time pressure is excessive, due to inside and outside pressure equal principle, the glass cap 62 on pressure release glass tube 6 will by jack-up, and gas is released from the relief hole of two on pressure release glass tube 6 61, when air pressure recovers normal time, glass cap 62 will fall, and just in time cover two relief holes 61 on pressure release glass tube 6, and pressure release venting terminates.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
