Abstract
The utility model discloses a kind of oil-filled transformer, comprise transformer body and underframe, it arranges the soft rubber pad of tool pooling feature between transformer body and underframe, and at the bottom of underframe and fuel tank between be that the combination of stationary state configures; Described transformer body top is provided with oil level indicator; Aluminium foil winding coil is provided with in described transformer body.The utility model devises oil level indicator at transformer top, thus can prevent the generation of oil leakage phenomenon; Adopt aluminium foil winding, have excellent anti-short circuit capability and lightning impulse resistant ability, heat dispersion is good, and cost is low, and coiling is convenient.
Description
Technical field
The utility model relates to a kind of oil-filled transformer.
Background technology
Oil-filled transformer is distinguished according to the number of phases of single transformer, can be divided into three-phase transformer and single-phase transformer.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.
The winding coil of existing transformer mostly adopts paper covered wire, paper covered wire is the one of electromagnetic wire, and be the winding coil being used for manufacturing various oil-filled transformer specially, its outside has good insulating properties, inside has good conductivity, and it is the heart of transformer.But the useful life of this paper covered wire is shorter, and cost is high, anti-short circuit capability and lightning impulse resistant ability.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of oil-filled transformer.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of oil-filled transformer of the utility model, comprise transformer body and underframe, it arranges the soft rubber pad of tool pooling feature between transformer body and underframe, and at the bottom of underframe and fuel tank between be that the combination of stationary state configures; Described transformer body top is provided with oil level indicator; Aluminium foil winding coil is provided with in described transformer body.
The beneficial effect that the utility model reaches is:
The utility model devises oil level indicator at transformer top, thus can prevent the generation of oil leakage phenomenon; Adopt aluminium foil winding, have excellent anti-short circuit capability and lightning impulse resistant ability, heat dispersion is good, and cost is low, and coiling is convenient.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of oil-filled transformer of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of oil-filled transformer, comprise transformer body 1 and underframe 2, it arranges the soft rubber pad 3 of tool pooling feature between transformer body 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 transformer body 1 top is provided with oil level indicator 5; Aluminium foil winding coil 6 is provided with in described transformer body 1.
The utility model devises oil level indicator at transformer top, thus can prevent the generation of oil leakage phenomenon; Adopt aluminium foil winding, have excellent anti-short circuit capability and lightning impulse resistant ability, heat dispersion is good, and cost is low, and coiling is convenient.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
