Description
Technical field
This utility model belongs to field of electrical equipment, is specifically related to a kind of oil-immersed power transformer with oil-leakage-prevention function。
Background technology
Transformator (Transformer) be the principle utilizing electromagnetic induction to change the device of alternating voltage, be the important step of the transmission of electric energy, distribution and use。Transformator is divided into dry-type transformer and oil-filled transformer by the type of cooling。Oil-filled transformer relies on oil to make cooling medium, such as oil, oil, oil immersed water cool, forced oil-circulation etc.。Transformer oil specific heat is big, and cooling is effective。And transformer oil has the many dielectric strength higher than air, moreover it is possible to play the effect eliminating electric arc。Therefore oil-filled transformer is widely used in power system, industrial and mining establishment, traffic, postal and telecommunication entities etc. needs the occasion of conversion voltage。
But oil-filled transformer operationally can produce vibrations, long-time vibrations can cause the components and parts of inside loosen or damage, and also can affect sealing member thus causing transformer oil seepage。These all directly affect the service life of oil-filled transformer。In addition the transformer oil in oil-filled transformer due to variations in temperature expansion or shrinkage, air can be entered in oil conservater。Therefore it is provided with dessicator at the air inlet of oil conservater, for the dry air entered。And in dessicator desiccant water suction saturated after need to be replaced, change troublesome work efficiency low。
Summary of the invention
The purpose of this utility model is to provide a kind of oil-immersed power transformer with oil-leakage-prevention function, this transformator good stability, effectively increases the service life。
For achieving the above object, this utility model be the technical scheme is that a kind of oil-immersed power transformer with oil-leakage-prevention function, and including housing, the outer both sides of housing are respectively provided with oil purifier and radiator；Described radiator is provided above oil conservater, and oil conservater is connected with gas relay；The air inlet of described oil conservater arranges dessicator；Described housing is arranged below damping base；Described damping base includes upper strata and bottom, is provided with damping chamber between upper strata and bottom；Described damping intracavity is provided with the shock reducing structure of some π types, and top and the leg of adjacent shock reducing structure all offset；Described damping intracavity is filled with rubber grain；
Multiple drying layer is set in described dessicator, in drying layer, places desiccant；The plurality of drying layer alternating inclinations is arranged, and is interconnected；Correspondence drying layer one end above in described dessicator arranges desiccant inlet, and one end that corresponding drying layer is positioned below arranges desiccant outlet；Described desiccant inlet connects desiccant reserve tank, and desiccant outlet connects desiccant collection box；Described desiccant inlet and desiccant outlet arrange control valve, in described dessicator, induction apparatus is set。
Preferably, described housing lower end arranges oil discharging valve。
Preferably, described gas relay side arranges pressure-relief vent。
Preferably, described pressure-relief vent is obliquely installed。
This utility model has the advantages that this transformer shell is arranged below damping base, can effectively damping, it is prevented that internal component loosens or damages；And ensure the sealing property of sealing member, it is prevented that transformer oil seepage；Effectively increase the service life。Damping intracavity in damping base is provided with some π type shock reducing structures, and top and the leg of adjacent shock reducing structure all offset。When shock reducing structure top is under pressure, by leg by force dispersion to adjacent shock reducing structure, good stability。The dessicator arranged on transformator, controls desiccant inlet and the open and-shut mode of desiccant outlet by controlling valve。When the desiccant in drying layer absorbs water saturated, desiccant inlet and desiccant outlet are opened simultaneously。Having inhaled water saturated desiccant and entered desiccant collection box, desiccant brand-new in desiccant reserve tank then enters drying layer。Staff only need to add desiccant to desiccant reserve tank, and reclaims the desiccant of desiccant collection box, work efficiency height。

Detailed description of the invention
As Figure 1-3, a kind of oil-immersed power transformer with oil-leakage-prevention function, including housing 1。Being provided with winding 14 in housing 1, winding 14 is internal is provided with iron core 13。During use, the bushing 7, shunting switch 8 and the low-tension bushing 9 that are sequentially arranged above by housing 1 access in circuit, and winding 14 realizes electromagnetic induction and changes voltage。The outer both sides of housing 1 are respectively provided with oil purifier 2 and radiator 3；Described radiator 3 is provided above oil conservater 4, and oil conservater 4 is provided with oil meter 11；Oil conservater 4 is connected with gas relay 10；The air inlet of described oil conservater 4 arranges dessicator 6。
Described housing 1 is arranged below damping base 5。Damping base 5 can effectively damping, it is prevented that internal component loosens or damages；And ensure the sealing property of sealing member, it is prevented that transformer oil seepage；Effectively increase the service life。As in figure 2 it is shown, described damping base 5 includes upper strata 51 and bottom 54, between upper strata 51 and bottom 54, it is provided with damping chamber；Described damping intracavity is provided with the shock reducing structure 52 of some π types, and top and the leg of adjacent shock reducing structure 52 all offset；Described damping intracavity is filled with rubber grain 53。When shock reducing structure 52 top is under pressure, by leg by force dispersion to adjacent shock reducing structure 52, good stability。
As it is shown on figure 3, arrange multiple drying layer 61 in described dessicator 6, in drying layer 61, place desiccant；The plurality of drying layer 61 alternating inclinations is arranged, and is interconnected, i.e. flap-like as illustrated in the drawing。The corresponding drying layer 61 in described dessicator 6 one end above arranges desiccant inlet 62, and one end that corresponding drying layer 61 is positioned below arranges desiccant outlet 63；Described desiccant inlet 62 connects desiccant reserve tank 64, desiccant outlet 63 connection desiccant collection box 65；Described desiccant inlet 62 and desiccant outlet 63 arrange control valve, in described dessicator 6, induction apparatus is set。Described induction apparatus can be that weight induction device or humidity sensor or both of which have。
The dessicator 6 arranged on transformator, controls desiccant inlet 62 and the open and-shut mode of desiccant outlet 63 by controlling valve。When the desiccant in drying layer 61 absorbs water saturated, desiccant inlet 62 and desiccant outlet 63 are opened simultaneously。Having inhaled water saturated desiccant and entered desiccant collection box 65, desiccant brand-new in desiccant reserve tank 64 then enters drying layer 61。Owing to desiccant replacing speed is relatively stable, therefore opening time can be set to fixing duration。It is to say, when induction apparatus arrival marginal value, control valve and control desiccant inlet 62 and desiccant outlet 63 unlatching, and unlatching duration is fixed。Desiccant so can be made to change completely, it is prevented that moisture enters oil conservater 4。Staff only need to add desiccant to desiccant reserve tank 64, and reclaims the desiccant of desiccant collection box 65, and work efficiency is high。
Described housing 1 lower end arranges oil discharging valve 12。Transformer oil can occur aging in running, and its dielectric strength assembly reduces。Therefore by oil discharging valve 12, aging transformer oil can be discharged in time, it is ensured that the normal operation of transformator。Described gas relay 10 side arranges pressure-relief vent 15, and described pressure-relief vent 15 is obliquely installed。Pressure-relief vent 15 can maintain the circulation of air, and is obliquely installed the moisture that can effectively absorb in fluid。
