Abstract
The utility model discloses a metallic polypropylene safety film used by a capacitor, comprising a polypropylene film, wherein a metal coating is provided on the polypropylene film, a plurality of T-shaped non-coating areas are arranged on the polypropylene film, and a plurality of rectangular non-coating areas which are arranged in one line with the heads of the T-shaped non-coating areas are also disposed on the polypropylene film. The utility model has a reasonable structure and can manufacture the capacitor which is formed of a plurality of small plates connected in parallel, wherein each small plate is a small capacitance, and a large capacitance is formed of a plurality of small capacitances connected in parallel. Even if a plurality of small capacitances are break through under the long-term working condition, the large capacitance can still insure that the integral capability of the whole capacitance is not affected, thereby greatly enhancing the security and the reliability of the capacitance.
Description
Technical field:
The utility model relates to a kind of capacitor film.
Background technology:
Existing capacitor metallized polypropylene film is whole metal cladding, when capacitor generation self-healing punctures, cause the loss of capacitor to increase, and cause capacitor self-heating amount to increase, and reduce the dielectric strength of condenser dielectric conversely, cause the inefficacy of capacitor or restrain explosion outward.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, favorable working performance, the capacitor of long service life metallized polypropylene safety diaphragm.
Technical solution of the present utility model is:
A kind of capacitor metallized polypropylene safety diaphragm, comprise the polypropylene rete, on the polypropylene rete, the coat of metal is set, it is characterized in that: on the polypropylene rete, be provided with a plurality of "T"-shaped no coating district, and on the polypropylene rete, be provided with head row's setting together that a plurality of rectangles do not have coating district and "T"-shaped no coating district.
The gap that rectangle does not have between the coating district is 0.8～1.5mm."T"-shaped no coating district is oblique " T " font.
The utility model is rational in infrastructure, can be made into one by many small plates capacitor that forms parallel with one another, each small plate becomes a little electric capacity, a big electric capacity is the electric capacity that is composed in parallel by many little electric capacity, even this electric capacity is because under the state of working long hours, when having several little electric capacity breakdown, guarantee that still the overall performance of whole capacitor is unaffected, thereby improved the fail safe and the reliability of electric capacity greatly.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
Embodiment:
A kind of capacitor metallized polypropylene safety diaphragm, comprise the polypropylene rete, the coat of metal 1 is set on polypropylene rete 4, on the polypropylene rete, be provided with a plurality of "T"-shaped no coating district 2, and on the polypropylene rete, be provided with head row's setting together that a plurality of rectangles do not have coating district 3 and "T"-shaped no coating district 2.The gap that rectangle does not have between the coating district 3 is 0.8～1.5mm, forms fuse."T"-shaped no coating district 2 is oblique " T " font.
Claims (3)
1, a kind of capacitor metallized polypropylene safety diaphragm, comprise the polypropylene rete, on the polypropylene rete, the coat of metal is set, it is characterized in that: on the polypropylene rete, be provided with a plurality of "T"-shaped no coating district, and on the polypropylene rete, be provided with head row's setting together that a plurality of rectangles do not have coating district and "T"-shaped no coating district.
