Abstract
The invention discloses an oil immersed transformer outer shell which comprises a shell body and a bottom frame. A soft rubber mat with a buffering function is arranged between the shell body and the bottom frame, and the bottom frame and the bottom of an oil tank are fixedly combined; an oil level gauge is arranged on the top of the shell body. The oil level gauge is arranged on the top of a transformer, and the oil leakage phenomenon can be avoided.
Description
Technical field
The present invention relates to a kind of oil-filled transformer shell.
Background technology
Distinguish according to the number of phases of single transformer, three-phase transformer and single-phase transformer can be divided into.In three-phase electrical power system, generally apply three-phase transformer, when capacity excessive and by transportation condition restriction time, in three-phase electrical power system, also can apply three single-phase type transformers composition transformer group.Divide according to the number of winding, two winding transformer and three-winding transformer can be divided into.Common transformer is all two winding transformer, on iron core, namely have two windings, and one is primary winding, and one is auxiliary winding.Three-winding transformer is the transformer (more than 5600 kilovolt-amperes) that capacity is larger, in order to connect three kinds of different voltage power lines.In a special case, the transformer applying more Multiple coil is also had.Classify according to version, then can be divided into core-type transformer and shell-type transformer.As winding wraps in iron core periphery then for core-type transformer; As iron core wraps in winding periphery then for shell-type transformer.The two is only structurally slightly different, and principle does not have the difference of essence.Power transformer is all iron core type.Divide according to insulation and cooling condition, oil-filled transformer and dry-type transformer can be divided into.In order to reinforced insulation and cooling condition, the iron core of transformer and winding all together with immerse and filled in the fuel tank of transformer oil.Under special circumstances, such as, at street lamp, during mine lighting, also use dry-type transformer.In addition, the special transformer of various special purpose is still had.Such as, test high-tension transformer, furnace transformer, the transformer in electric welding transformer and controllable silicon circuit, for voltage transformer and the current transformer of measuring instrument.
Mainly welding quality is bad, there is rosin joint, and sealing-off exists pin hole in weld seam, the defects such as sand holes, and because having welding agent and paint to cover when oil-filled transformer dispatches from the factory, after running, hidden danger just comes out, and splits in addition, cause seepage because electric and magnetic oscillation can make welding shake.For there is Seepage, first finding out breakthrough, can not omit.The metal tools such as flat chisel or sharp punching pin can be adopted to be rivetted by breakthrough for the serious position of seepage, will administer removing surface totally after controlling leakage, the polymer composite that adopts is cured more at present, can reach the object of long-term improvement seepage after solidification.
Easily there is the phenomenon of leakage of oil in existing oil-filled transformer shell, primarily of following some:
(1) poor sealing reason.Usual case edge and the sealing of case lid adopt oil resistant rubber rod or rubber seal, if its joint processes bad meeting cause leakage of oil fault.Have plenty of and use plastic tape colligation, what have directly forces together two terminations, and roll during owing to installing, interface can not be fastened, and does not have sealing function, is still leakage of oil.Available good fortune generation blue material carries out bonding, and make joint form entirety, oil seepage phenomena obtains very large control; If easy to operate, also can metal shell be carried out bonding simultaneously, reach treating seepage object.
(2) flange connections leakage of oil.Flange surface is uneven, and fastening bolt loosens, and mounting process is incorrect, makes bolted bad, and causes leakage of oil.First loosening bolt is carried out fastening after, encapsulation process is implemented to flange, and for may the bolt of seepage also process, reaches and administer object completely.Carry out fastening to the bolt loosened, must operate in strict accordance with operating procedure.
(3) bolt or gas pipe thread leakage of oil.Process coarse when dispatching from the factory, poor sealing, oil-filled transformer just produces leakage of oil fault after sealing a period of time.Adopt macromolecular material that bolt is carried out encapsulation process, reach the object of administering seepage.Another kind of way is screwed out by bolt (nut), after the blue release agent of surface smear good fortune generation, then carries out fastening after surface smear material, can reach improvement object after solidification.
(4) ironcasting leakage of oil.Leakage of oil main cause is that ironcasting has caused by sand holes and crackle.For crackle seepage, boring stop hole is the best approach avoiding extending that eliminates stress.According to the situation of crackle, leak source can be squeezed into galvanized wire or rivets with hand hammer during improvement.Then with acetone, breakthrough is cleaned up, seal with material.Casting sand hole then can seal by direct material.
(5) radiator leakage of oil.Be formed in radiating tube sweep through punching press after the radiating tube of radiator normally flattens with seamed steel pipe and welding portion often produces leakage of oil, this is because during punching press radiating tube, the outer wall of pipe is by tension force, and its inwall is stressed, and exists caused by residual stress.Upper and lower for radiator panel valve (butterfly valve) is closed, oil in radiator is cut off with oil in casing, reduces pressure and leakage.Carry out suitable surface treatment after determining seepage place, then adopt good fortune generation blue material to carry out sealing and administer.
(6) porcelain vase and glass oil ga(u)ge leakage of oil.Normally because Rig up error or seal failure made.The materials such as metal, pottery, glass can well be carried out bonding by polymer composite, thus reach the basic improvement of leakage of oil.
Therefore, develop a kind of oil-filled transformer shell of leakage of oil that can prevent and become problem demanding prompt solution.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of oil-filled transformer shell.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of oil-filled transformer shell of the present invention, comprise housing and underframe, it arranges the soft rubber pad of tool pooling feature between housing and underframe, and at the bottom of underframe and fuel tank between be that the combination of stationary state configures; Described case top is provided with oil level indicator.
The beneficial effect that the present invention reaches is:
The present invention devises oil level indicator at transformer top, thus can prevent the generation of oil leakage phenomenon.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of oil-filled transformer shell of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of oil-filled transformer shell, comprise housing 1 and underframe 2, it arranges the soft rubber pad 3 of tool pooling feature between housing 1 and underframe 2, and is that the combination of stationary state configures between 4 at the bottom of underframe 2 and fuel tank; Described housing 1 top is provided with oil level indicator 5.
