Any one in formic acid glycol ester, makrolon, polystyrene, polyethylene, polyvinyl chloride, polyphenylene sulfide or its knot
It closes；The thickness of macromolecule membrane is 0.5 μm~50 μm；
Metallization complex media macromolecule membrane capacitor of the present invention is the complex media macromolecule membrane layer that will metallize
Folded the misplace cylinder for rolling into core or the flattening type capacitor body without core, gold is sprayed at capacitor body both ends
Belong to, then capacitor is made after the capacitor body individually or is in parallel or series combined.
Beneficial effects of the present invention in summary：（1）Due to Al2O3Relative dielectric constant be 9.5~11.2, by Al2O3
Vacuum evaporation can greatly improve relative dielectric constant on film as a part of of dielectric, be carried under unit volume
The capacitance of high capacitance；（2）Al2O3Thermal coefficient reached 24~30W/（m*k）, improve the heat biography of capacitor body
It leads, the heat that medium generates is exported as early as possible, the Temperature Distribution of capacitor internal is optimized, improves the heat resistance of capacitor；
（3）Traditional metallization macromolecule membrane also possesses self-healing performance, but the heat that self-healing generates be after it cannot effectively export,
It can cause to increase with the levels film temperature of self-healing area joint, reduce these region pressure resistance performances, occur continuous excessive
Self-healing causes dielectric breakdown to be carbonized, so as to cause the thorough damage of capacitor.And there is Al2O3The metalized film of insulating layer is being sent out
After being born from more, the heat of self-healing will be exported by rapid dispersion, prevent the generation of excessive self-healing, from the effect for playing isolation self-healing.
