Abstract
The utility model relates to a totally-coated insulating cover of a capacitor. The totally-coated insulating cover is applied to capacitors and comprises an upper insulating cover and a lower insulating cover, wherein the upper insulating cover is inserted in the lower insulating cover to form a closed space, the closed space contains a core of the capacitor and dipping oil, and the core of the capacitor and the dipping oil are separated from the metal shell of the capacitor in the space formed by the upper and lower insulating covers. According to the totally-coated insulating cover, the core of the capacitor and the dipping oil can be totally coated in the closed space formed by combining the upper insulating cover and the lower insulating cover, so that the risk that a pole shell of the capacitor can be broken-down is avoided, and the insulting level of the pole shell of the capacitor can be increased.
Description
Technical field
The utility model relates to a kind of insulating cover, relates in particular to the full coated insulation cover of a kind of capacitor.
Background technology
The metal shell AC capacitor has used insulating cover to keep the utmost point shell insulation level of capacitor, and prevents that utmost point shell punch-through from appearring in capacitor.But this insulating cover is not full clad type, and sizable metal part branch contacts with impregnation oils on the capacitor case.If when containing the metal spraying ash particle that comes off on the capacitor body in the impregnation oils, can reduce the utmost point shell insulation level of capacitor.If during the capacitor body run-off the straight, the gilding layer that certain end face of capacitor possibly occur directly contacts with metal shell, causes the capacitor pole shell to puncture and loses efficacy.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of capacitor full coated insulation cover, has used the capacitor of this insulating cover, and utmost point shell insulation level is improved, and can not occur that utmost point shell punctures and the inefficacy that causes.
The utility model is achieved in that the full coated insulation cover of a kind of capacitor; It is applied in the capacitor; The full coated insulation cover of said capacitor comprises insulating cover and following insulating cover; The said insulating cover of going up inserts down in the insulating cover and forms confined space, and said seal cavity has held the capacitor body and the impregnation oils of said capacitor, and the capacitor body of said capacitor and impregnation oils are isolated between the metal shell of said upper and lower insulating cover and said capacitor.
As the further improvement of such scheme, the said insulating cover of going up comprises upper and lower two domes, and the diameter of said bottom dome is littler than the diameter of said top dome, and the afterbody wall thickness of said bottom dome inwardly shrinks.
As the further improvement of such scheme, said insulating cover down is a round cup shape object, and its top wall thickness outwards shrinks.
The full coated insulation cover of said capacitor can be coated on the capacitor body of capacitor and impregnation oils entirely in the enclosure space that insulating cover and following insulating cover be combined to form, thereby thoroughly do away with the risk that the capacitor pole shell punctures, increase capacitor pole shell insulation level.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please consult Fig. 1 to Fig. 5 in the lump, the full coated insulation cover of capacitor, it is applied in the capacitor, and the full coated insulation cover of said capacitor comprises insulating cover 1 and following insulating cover 2, and last insulating cover inserts in the insulating cover and the formation confined space.
Different because of the height of different capabilities and voltage capacitor, cause the height of confined space of needs also different.So for same diameter but highly different capacitors, the full coated insulation cover that is suitable for, last insulating cover 1 is identical, following insulating cover 2 be a series of height different but all the other measure-alike parts, with the highly different capacitor demand of use.
Please consult Fig. 6 and Fig. 7 in the lump, this figure is the structural representation of the metal shell AC capacitor of the full coated insulation cover of capacitor using the utility model preferred embodiments and provide.Insert in the insulating cover 2 down and in the confined space that forms, held capacitor body 3 and impregnation oils 6 at last insulating cover 1, last insulating cover 1 and following insulating cover 2 are kept apart they and metal shell 5 fully, and capacitor is through drawing cover plate 4 extraction electrodes.
In sum; The full coated insulation cover of the capacitor that the utility model provides; Can the capacitor body of capacitor and impregnation oils be coated in the enclosure space that insulating cover and following insulating cover be combined to form entirely, thereby thoroughly do away with the risk that the capacitor pole shell punctures, increase capacitor pole shell insulation level.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection range of the utility model.
