Description

A kind of oil storage tank of oil immersed transformer

Technical field

The utility model relates to a kind of oil conservater, specifically a kind of oil storage tank of oil immersed transformer belongs to oil immersed type Transformer oil storage technical field of improvement.

Background technique

Oil-immersed transformer is furnished with oil conservater, and the oil of oil conservater is communicated with the oil in fuel tank, and the effect of oil conservater is It is changed for adjusting volume of the transformer oil under temperature variations, when oil temperature increases, oil volume becomes larger, on oil conservater Pasta can rise, and when oil temperature reduces, oil volume becomes smaller, and the pasta of oil conservater can decline.In order to guarantee the pressure in fuel tank not It causing in excessive, when design is that oil conservater top tank air is required to be connected with outside air, but when outside air humidity is big, water Oil conservater will be entered and pollute transformer oil by dividing, and when water content is above standard value 20mg/L, it is exhausted to will lead to transformer oil The adverse consequences such as edge performance declines, dielectric loss is exceeded eventually lead to insulation breakdown, cause the serious safeties accidents such as short circuit, therefore store up Connecting tube and dehydrating breather can be all installed on Oil Tank, are connected to again with outside air by connecting tube with dehydrating breather.

Connecting tube is all using bend pipe at present, is all that mounting hole is opened up on the top surface of oil conservater, then when being installed Bend pipe one end is protruded into mounting hole and is fixed by flange welding, dehydrating breather is installed on the other end.Due to be will be in oil conservater Top surface opens up mounting hole and by flange welding, and one side technique is cumbersome, and welding effect is poor, on the other hand welds existing defects When (such as sand holes), often it is not easy to be found, rainwater will be directly entered in oil conservater, and since the density of water is greater than oil Density, rainwater will be directly entered oil tank of transformer and transformer oil is made phenomena such as decreasing insulating, insulation breakdown occur, To damage transformer.Furthermore current dehydrating breather structure generally only includes simple glass tank, upper cover, lower cover, gasket and drying Agent not only only serves moisture absorption effect, and moisture absorption less effective, and the moisture absorption service life is short, needs artificial repeatedly replacement, undoubtedly improving makes Use cost.

Utility model content

In view of the above-mentioned problems, the problem of the utility model intends to solve is to provide, one kind is simple and reasonable, use cost is low, Simple process, long service life, safety in utilization is good and filters the good oil storage tank of oil immersed transformer of moisture absorption effect, effectively avoids There is phenomena such as decreasing insulating, insulation breakdown in transformer oil.

In order to achieve the above objectives, the utility model uses a kind of following technical scheme: oil storage tank of oil immersed transformer, including Oil conservater ontology, the oil conservater body bottom portion offer a mounting hole, and a straight tube is welded in the mounting hole, described Straight tube arranges that described straight tube one end is located at the oil conservater ontology inner top position vertically, and the other end stretches out the oil conservater sheet In vitro, and on the end it is connected with a dehydrating breather, the dehydrating breather includes glass tank body, upper cover, lower cover, oil storage tank and respiratory siphon, The upper cover and the lower cover are separately fixed at the both ends of the glass tank body, and the upper lid is equipped with a flange, the moisture absorption Device is fixed on straight tube by the flange, and the first desiccant is filled in the glass tank body, is further fixed on the lower lid One oil storage tank, the oil storage tank bottom end are connected with a respiratory siphon, and the respiratory siphon is connected with the oil storage tank, the respiratory siphon For a bend pipe, it is filled with the second desiccant in another open end of the respiratory siphon, in the oil storage tank and the respiratory siphon also Be filled with transformer oil, and in the respiratory siphon liquid level of transformer oil and transformer oil in the oil storage tank liquid level phase It is flat.

Preferably, the material of the glass tank body is doubling implosion guard.

Preferably, first desiccant is discoloration silica gel, second desiccant is active carbon desiccant.

Effective achievement of the utility model: the utility model is simple and reasonable, and mounting hole is opened in oil conservater ontology Situations such as bottom, straight tube are directly weldingly fixed in the mounting hole of bottom, not only simple process, and there are sand holes when if welding When, it may appear that transformer oil leakage phenomenon is effectively kept away a possibility that being easily found, safeguarded in time, while having prevented water inlet Exempt from transformer oil and phenomena such as decreasing insulating, insulation breakdown occur, greatly improves safety in utilization；Dehydrating breather is finished Structure improves, and increases oil storage tank and respiratory siphon, and transformer oil is filled in oil storage tank and respiratory siphon, while the one of respiratory siphon The second desiccant is filled in open end, the air with impurity moisture is no longer to be directly entered in glass jar body, but first pass through Second desiccant carries out the moisture absorption, then carries out contaminant filter by the transformer oil in respiratory siphon and oil storage tank, finally passes through glass Intracorporal first desiccant of tank carries out the moisture absorption again, it is good not only to filter moisture absorption effect, and substantially prolong making for the first desiccant With the service life, manual maintenance amount is reduced, reduces use cost；The material of glass tank body is set as doubling implosion guard, is effectively enhanced Mechanical strength reduces the phenomenon that leading to tank rupture because colliding in use process generation；First desiccant is set as discoloration silica gel, Second desiccant is set as active carbon desiccant, and one side air is filtered the moisture absorption by active carbon desiccant, further increases Moisture absorption effect is filtered, whether the silica gel that on the other hand directly can judge to change colour by the color change of observation discoloration silica gel fails, Replacement convenient for safeguarding.

In conclusion the utility model has, simple and reasonable, use cost is low, simple process, long service life, makes With the feature that safety is good and moisture absorption effect is good, effectively transformer oil is avoided phenomena such as decreasing insulating, insulation breakdown occur.
