Abstract
The utility model discloses an improved ventilated transformer shell, which belongs to the field of manufacturing of a transformer, and is characterized in that the upper part of a shell is a movable baffle, the movable baffle is provided with an air inlet and an air outlet, the air inlet is provided with a fan, and a power line of the fan is directly connected to a power input lead of the transformer in the shell; meanwhile, a ceramic cushion layer is embedded in the inner lateral surface of the shell, the ceramic cushion layer is 10-20 mm thick, and the shape of the ceramic cushion layer is matched with the shape of the shell of the ventilated transformer. The ventilated transformer shell, provided by the utility model, is good in radiating effect, and is capable of ensuring a transformer body to operate for a long time without overheating, so that the service life of the transformer is improved, and the safety hidden trouble in a using process of the transformer is reduced.
Description
Technical field
The utility model relates to transformer case, is specially and a kind ofly protects the transformer internal structure, can be the ventilated type transformer case that transformer coil heat radiation is offered help simultaneously.
Background technology
Power transformer product is the very important kind equipment of power department always, and the transformation of carrying voltage and electric current is main with dried piezoelectric transformer of cast-type and the dried piezoelectric transformer of impregnated again in the existing transformer; Wherein the dried piezoelectric transformer of cast-type mainly is to be the cast raw material with epoxy resin, coil is poured into a mould form in vacuum equipment, and the thermal endurance class of this transformer is low; And epoxy resin is organic substance; At high temperature easy firing can produce a large amount of flue gases, thereby cause fire easily in naked light.And the dried piezoelectric transformer of impregnated forms through the glass fiber covered wire coiling, and the insulating cylinder of device body theater and stay all are by the separate material coiling, and is mostly to use paper material, and its humidity resistance is poor, the high temperature insulation grade is low.Need look for a kind of novel housing to come the auxiliary transformer body to dispel the heat in view of these reasons, in order to optimizing the inner heat dispersion of transformer, thereby improve transformer useful life.
The utility model content
The technical problem that the utility model solved is to provide a kind of ventilated type transformer case, and this stay curtain can be realized the heat radiation of interior loop and the coiling of exterior loop, can be in order to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of ventilated type transformer case; Be a shell structure, its housing top is movable baffle plate, has air inlet and air outlet on this movable baffle plate; Air inlet is provided with fan, and the power line of this fan directly connects on the interior power of transformer input lead of shell; Simultaneously, at the also embedded ceramic bed course of the medial surface of housing, said ceramic blanket layer thickness is 10 ~ 20mm, and should the fit shell shape of ventilated type transformer of its shape.
In the utility model, the manner of said movable baffle plate is a draw and insert-type.
In the utility model, be provided with metal filter screen on said air inlet and the air outlet.
In the utility model, for guaranteeing fitting tightly of ceramic bed course and case body, connecting bolt capable of using carries out fastening to it.
Beneficial effect: the utility model technology is simple, and is easy to process, and assembling easily; Do not influencing under the normal situation about using of transformer, improving the performance of ventilation and heat dispersion of transformer, making the transformer operation more reliable; To increase the useful life of transformer body, simultaneously, reduce potential safety hazard.
Description of drawings
Fig. 1 is the sketch map of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of ventilated type transformer case of Fig. 1; In the present embodiment, comprise transformer housing 1, internal coil 2, input lead 6, output lead 7 and ceramic bed course 9, wherein; Pottery bed course 9 is embedded on the inner surface of transformer housing 1; Transformer housing 1 is provided with air inlet 4 and air outlet 3, and air inlet 4 is provided with fan 5, and the power line of fan 5 directly is connected on the power of transformer output lead 7.
In the present embodiment, in case transformer is switched on, fan 5 promptly begins to rotate; Carry out the cross-ventilation circulation via air inlet 4 and air outlet 3; Impel the cooling of transformer interior loop, simultaneously, ceramic bed course 9 also can effectively guarantee the inside and outside heat exchange of shell of transformer housing 1.
In the present embodiment, on air inlet 4 and air outlet 3, be provided with screen pack 8, cause inner dust excessively to pile up and damage in order to prevent that the outer dust of transformer from getting into.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
