Abstract
The purpose of the utility model is to disclose a pipe type oil-level gauge, comprising a pipe, a buoy indicating device, and a window, the pipe is installed on the oil tank cover of a transformer, the upper end of the pipe is provided with a cover body, the buoy indicating device is disposed in the pipe, the lower part of the buoy indicating device is provided with a buoy display used for indicating the normal state of the oil level, the upper part of the buoy indicating device is provided with a buoy display used for indicating the abnormal state of the oil level, the window adopts the glass pipe built-in structure to be disposed inside the upper part of the pipe; via the window disposed in the pipe, when the window displays the buoy display which indicates the normal state of the oil level, the oil level is in a normal state, the oil level is above the tank cover; when the window displays the buoy display indicating the abnormal state of the oil level, the oil level is in an abnormal state, the oil level is below the tank cover; oil supplement should be performed properly, the pipe type oil-level gauge is advantaged by intuitively displaying oil level of oil tank in transformer, simple structure, and realizing purpose.
Description
Technical field
The utility model relates to a kind of tubular type oil level indicator, particularly a kind of tubular type oil level indicator that is used for the oil level in the oil immersed type full-sealed transformer demonstration oil tank of transformer.
Background technology
Be installed at present on the oil immersed type full-sealed transformer, the oil level indicator that shows its oil level mainly contains two kinds, first kind of oil level indicator is to have inspection hole on a metal tube, and sealing is equipped with the glass tube of observation oil level or the parts of glass plate on inspection hole, float more easy to identify is arranged in metal tube, for example float is a red color, and the position that float shows is the position of pasta.But inspection hole is higher than the fuel tank cap upper surface, when oil level near the case lid position, float is shown as does not have oil, can not accurately show the minimum oil level of fuel tank internal upper part.
Second kind of oil level indicator is to be equipped with the mark spare that shows the oil level mark on float, solved the inaccurate problem of minimum oil level that shows the fuel tank internal upper part better.Second kind of oil level indicator is equipped with valve part, also can exit, gather gas sample, pressure release etc.
But the structure of above-mentioned second kind of oil level indicator still has the following disadvantages:
1), described mark spare is to float in body with float, not only fluctuate, also can rotate around the axis of body, and generally has only the view window of opening half along the sectional position of body axis normal on the body, require mark on the mark spare no matter mark spare rotates to any angle and can both see at view window, this just causes the oil level show state of oil level indicator to discern with color, and can not discern with literal; The mark color, before using transformer, the user need read the operation instructions of oil level indicator, could understand the implication of marker color representative, and it is more directly perceived than color mark to mark with literal, adopts word marking to be limited but the rotation of mark spare makes;
2), float and mark spare separately make, and is assembled into the parts that can fluctuate again, the deficiency that this structure exists is: a), float and mark spare split assembling, its binding site may have loosening, thereby influence shows the accuracy of oil level; B), the step of the binding site of float and mark spare, make float endoporus aperture be restricted, therefore the float endoporus aperture of this oil level indicator generally is less than φ 15mm, with latus rectum on the oil level indicator be that the pressure relief valve of φ 25mm does not match, thereby influence the effect of the action of pressure relief valve; C), float and mark spare split package assembly, increased the manufacturing cost of oil level indicator;
3), float is contained in the bottom in the body, and the gap is less between body and the float, also influences the responsiveness of pressure relief valve.
Therefore, need a kind of tubular type oil level indicator especially, solved the problem of above-mentioned existing existence.
The utility model content
The purpose of this utility model is to provide a kind of tubular type oil level indicator, at the deficiencies in the prior art, can very show the oil level of fuel tank in the transformer intuitively, and is simple in structure.
The technical matters that the utility model solved can realize by the following technical solutions:
A kind of tubular type oil level indicator, it is characterized in that, it comprises body, buoy indicating device and form, described body is installed on the fuel tank case lid of transformer, the upper end of described body is provided with lid, described buoy indicating device is arranged in the described body, the bottom of described buoy indicating device is provided with and is used to indicate the normal buoy of oil level to show, the top of described buoy indicating device is provided with and is used to indicate the unusual buoy of oil level to show, described form adopts the glass tube embedding structure to be built in the top of described body.
In an embodiment of the present utility model, described body is welded on the fuel tank case lid of transformer by flange seat.
Further, be provided with packing washer in the described flange seat.
Further, be connected by bolt between described body and the described flange seat.
In an embodiment of the present utility model, described buoy indicating device is provided with guard shield.
In an embodiment of the present utility model, described lid is provided with and is used to the interface that connects oily connecting leg, pressure relief valve and vacuumize.
In an embodiment of the present utility model, the surface of described body is provided with electrostatic coating.
Tubular type oil level indicator of the present utility model by being arranged on the form of body, shows that in form the normal buoy of oil level shows that the expression oil level is normal, and oil level is on case lid; Show that in form the unusual buoy of oil level shows that the expression oil level is unusual, oil level needs suitable repairing below case lid, very show the oil level of fuel tank in the transformer intuitively, and is simple in structure, realizes the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is the structural representation of tubular type oil level indicator of the present utility model;
Fig. 2 be among Fig. 1 A to structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, tubular type oil level indicator 100 of the present utility model, it comprises body 110, buoy indicating device 120 and form 130, body 110 is shaped by aluminium alloy compression casting, appearance looks elegant, in light weight, corrosion-resistant, do not have and return embroidery; The surface of body 110 is provided with electrostatic coating, and the strong adhesion of lacquer, nothing are peeled off; Form 130 adopts special glass pipe embedding structure.
