Background technology
Metal metallized safety film is a kind of improved metal film, and structure generally includes some regularly arranged pole plate unit, and each pole plate unit connects pole plate unit around by microfuze; Its advantage had is when arbitrary pole plate unit punctures, namely be short-circuited between capacitor film the two poles of the earth, thus discharge and produce electric arc, because the ampacity in microfuze region is less, therefore can have precedence over pole plate unit and fuse, thus the self-healing time of capacitor film can be reduced, reduce the burn surface area of medium and caloric value when reducing capacitor film self-healing, improve stability and the safety in utilization of capacitor film.In prior art, the maximum deficiency of metal metallized safety film is that clearance for insulation occupies the effective area of metalized film, cause the production cost of metal metallized safety film high and volume is large, and the area reducing clearance for insulation is difficult to ensure the insulation property between pole plate unit.
For this reason, Chinese patent literature CN203931820U discloses a kind of double-layer partition metal metallized safety film, it can improve the effective area of metalized film under the prerequisite ensureing the insulation property between pole plate unit, thus reduces the production cost of metal metallized safety film and reduce its volume.But it is to roll or superimposedly makes the capacitor core period of the day from 11 p.m. to 1 a.m, and usually need to place a dielectric film between two metallized films, therefore operating efficiency is lower; And due to any one side pole plate unit between spacing comparatively large, comparatively convention security film is poor to cause heat dispersion, needs further improvement.
Summary of the invention
The utility model is just for the deficiency that prior art exists, a kind of double-layer partition metallized film of high heat radiation is provided, under the prerequisite that area of remaining valid is large, improve its heat dispersion and the operating efficiency being processed into the capacitor core period of the day from 11 p.m. to 1 a.m, meet actual operation requirements.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of double-layer partition metallized film of high heat radiation, comprise banded basement membrane and laminating at described epilamellar metallization vapor-deposited film, described metallization vapor-deposited film comprises the pole plate unit of some rectangles, described pole plate unit interval is regularly arranged makes to have the clearance for insulation identical with described pole plate cell configuration between described pole plate unit, described pole plate cell distribution is in the upper and lower surface of described basement membrane, and the clearance for insulation below the corresponding basement membrane of pole plate cell position above basement membrane, pole plate unit below the corresponding basement membrane in clearance for insulation position above basement membrane, described basement membrane is provided with through hole, and described through hole is arranged at the position at described pole plate unit four angles, safety fuse is provided with in described through hole, and described safety fuse connects the pole plate unit above described basement membrane and the pole plate unit below described basement membrane, also comprise the insulating heat-conductive pellosil being arranged at described basement membrane two sides, described metallization vapor-deposited film is between described basement membrane and described insulating heat-conductive pellosil.
As the improvement of technique scheme, the blank described basement membrane being also provided with all not laminating described metallization vapor-deposited film in two sides stays limit, described blank stays limit and described metallization vapor-deposited film to lay respectively at the both sides of described basement membrane, described metallization vapor-deposited film also comprises pole plate wiring limit, and some described pole plate unit stay between limit on described pole plate wiring limit and described blank; Described pole plate wiring limit is positioned at the one side of described basement membrane, the not laminating described metallization vapor-deposited film of another side of the described basement membrane that described pole plate wiring limit is corresponding.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The double-layer partition metallized film of a kind of high heat radiation described in the utility model, by arranging described insulating heat-conductive pellosil on described basement membrane two sides, both the problem of the larger poor radiation of spacing described in one side between pole plate unit had been overcome, overcome again the problem needing to place dielectric film between two metallized films, can under the prerequisite that area of remaining valid is large, improve its heat dispersion and the operating efficiency being processed into the capacitor core period of the day from 11 p.m. to 1 a.m, meet actual operation requirements.
