Abstract
The utility model relates to an interior convex metal corrugated sealing oil conservator, which comprises a conservator body of the oil conservator and an interior convex metal corrugated sealing oil tank which is arranged in the conservator body and is composed of a corrugated pipe, an upper cover plate and a lower cover plate, wherein a pressure plate is arranged on the upper cover plate of the corrugated pipe, a guiding sleeve is arranged on the pressure plate, a guiding pillar are arranged in the conservator body, a bracing frame with an oil-in is arranged on the bottom of the conservator body, the lower cover plate is positioned on the bracing frame, and the bottom of the corrugated pipe of the interior convex metal corrugated sealing oil tank is fixedly connected with a conservator seat of the conservator body. When the interior convex metal corrugated sealing oil tank is compressed or expands, the guide sleeve on the pressure plate moves up and down along the guide pillar. The utility model has the advantages that the compression or the expansion guidance of the interior convex metal corrugated sealing oil tank are accurate, free and stationary, which enables the interior convex metal corrugated sealing oil tank to receive the power evenly, thereby improving the service life of the corrugated pipe, reducing the ineffective compensation volume, saving the unnecessary ineffective oil reserve, even though the upper cover plate and the lower cover plate are closed closely, the corrugated pipe is further not in a limit compression state, thereby prolonging the service life of a transformer.
Description
Technical field:
The utility model relates to a kind of as liquid or the gas cubage compensation device when changing that expands, particularly a kind of can with the supporting use of various oil immersion power equipments, compensate the convex formula wavy metal sealing oil conservator of its volume-variation.
Background technology:
At present, with matching used its cabinet of inner oil type bellow oil conservator of oil immersion power equipment in the wavy metal leakproof fuel cell be to constitute by bellows and this upper and lower cover plate of managing upper and lower port that is placed in, when vacuumizing in the cabinet, the upper and lower cover plate tight closure of wavy metal leakproof fuel cell, bellows is in limit compressive state, and long-term the use useful life that can influence bellows increased the invalid compensation volume of wavy metal leakproof fuel cell, both influence useful life, increased oil consumption again.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of increasing the service life and convex formula wavy metal sealing oil conservator that oil consumption is few.
The purpose of this utility model is achieved in that it comprises the oil conservator cabinet and places the convex formula wavy metal leakproof fuel cell that is made of bellows and upper and lower cover plate in this cabinet, the bellows upper cover plate is provided with pressing plate, pressing plate is provided with guide pin bushing, be provided with guide pillar in the cabinet, it is characterized in that: the cabinet inner bottom part is provided with the bracing frame of bringing hydraulic fluid port into, lower cover places on this bracing frame, and the bellows bottom of convex formula wavy metal leakproof fuel cell is connected with cabinet cabinet seat.When compression of convex formula wavy metal leakproof fuel cell or expansion, the guide pin bushing on the pressing plate moves up and down along guide pillar.
The utility model has the advantages that the compression of convex formula wavy metal leakproof fuel cell or expand guiding accurately, freely, steadily, make convex formula wavy metal leakproof fuel cell stressed evenly, improve bellows useful life and reduced invalid compensation volume, save unnecessary invalid oil reserve, even upper and lower cover plate tight closure bellows is not in limit compressive state yet.Thereby along the useful life of having grown transformer.
Specify by way of example below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As seen from the figure, the utility model is by oil conservator cabinet 1, oil conservator cabinet seat 2, convex formula wavy metal leakproof fuel cell 3, upper cover plate 4, lower cover 10, bracing frame 17, all be fastened on the oil conservator cabinet seat 2 fixed installation pressing plate 5 and exhaust apparatus 6 on the fuel tank upper cover plate 4; Welding oil inlet pipe 12 on the fuel tank lower cover 10, vertical soldering stainless steel bellows 13 around the convex formula wavy metal leakproof fuel cell 3 has promptly been formed convex formula wavy metal sealing oil conservator.
When the utility model oil conservator vacuum was closed, fuel tank upper cover plate 4 was with fuel tank lower cover 10 complete closures, and at this moment, invalid compensation cellar for storing things is for minimum.When entering from oil inlet pipe 12 in the convex wavy metal leakproof fuel cell 3 with transformer oil after transformer is connected, fuel tank upper cover plate 4 and pressing plate 5 guide pin bushings, 15 exhaust apparatus 6 and written instructions oil ga(u)ge 8 rise to when the corresponding height of curve of ground temperature, air is discharged from exhaust apparatus 6.Temperature changes in transformer, and temperature raises, and oil volume increases, and transformer oil enters in the fuel tank 3 through oil inlet pipe 12, makes upwards elongation of bellows 13, and when oily temperature drop is low, oil volume reduces, and the oil in the fuel tank 3 enters transformer body through oil inlet pipe 12.Pressing plate 5 is pressing bellows 13 to shrink downwards, and is flexible up and down with the oil volume freedom like this.Guide pin bushing 15 is fixed on the pressing plate 5, and guide pillar 16 upper ends are fixed on the fixed head 14, and the lower end is fixed on the cabinet seat 2, has formed a vertical guider.Integral tank in the telescopic process, is that guide pin bushing 15 moves the effect of finishing the compensation oil mass on guide pillar 16 about in the of 3.This mode leads accurately, freely, lifting is steady, makes convex formula wavy metal leakproof fuel cell 3 stressed evenly, improved 13 useful lifes of corrugated stainless steel tubing.So both changed volume of fuel tank; adapting to oil volume again changes; operate steadily; oil is thoroughly isolated, protected to assurance transformer oil and air; and reduce invalid compensation volume; guaranteed transformer maximum compensation rate and saved unnecessary invalid oil reserve, thereby prolonged the service life of transformer.
