Description
Technical field
The present invention relates to DC filter capacitors make field, the specifically innovation optimization of fuse processing technology.
Background technology
The capacitor core subelement commonly using in the market is to terminate through cutting, winding, flattening, metal spraying, half survey,
Because its inner core unit is polymerized（Heat treatment）Technique, internal dissociated air easily causes metallized polypropylene film
Metal layer, long term accumulation can lead to internal energy accumulation serious, so that capacitor body is punctured or make the electric capacity that assembling finishes
There is bulge deformation, danger even on fire in device.
Content of the invention
The invention aims to making up the conventional technique making metalizing polypropylene thin film capacitor cartridge units
Defect and deficiency.
The solution of the present invention is:A kind of security performance height, thin film self-healing performance reliability, explosion-proof reliable electric capacity are provided
Device cartridge units, solve that existing capacitor core subelement is inflammable and explosive, of poor quality, poor reliability, short life the problems such as.
The described DC filter capacitors fuse processing technology of the present invention comprises the following steps：The first step, according to electric capacity
The rated voltage of device, determines the pressure thickness of thin film and proposes using specification film；Second step, by capacitor body two ends spraying plating electricity
Pole, guarantees before spraying plating that end face is smooth, ensures thickness uniformly after spraying plating, and peplos surface treatment is clean；3rd step, by capacitor core
Son carries out vacuum drying treatment, removes metallic film capacitor fuse thin film air plankton between layers, by reasonable
Contraction, make capacitor body thin film even closer between layers；4th step, the fuse after vacuum drying treatment is carried out directly
Stream is pressure and the dual test of ac voltage withstanding, effectively eliminates internal flaw point；5th step, by the fuse of test passes, by Copper Foil
Piece soldering connects capacitor case exit.
Effective effect that the present invention brings is, after DC filter capacitors fuse processing technology, to enable capacitor
The characteristic such as fuse voltage climbing speed is fast, high frequency performance is good, energy storage density is big, when by high current, has very high sensitivity
And spontaneous recovery can be effectively isolated after capacitor body spontaneous recovery puncture part, it is to avoid impact other parts it is ensured that whole capacitor interior
Portion's safe mass.
Specific embodiment
In order to further illustrate technical purpose and the technical scheme of the present invention, below the present invention is further elaborated：The
One step, according to the rated voltage of capacitor, determines the pressure thickness of thin film and proposes using specification film；Second step, by capacitor
Fuse two ends spraying plating electrode, guarantees before spraying plating that end face is smooth, ensures thickness uniformly after spraying plating, and peplos surface treatment is clean；The
Three steps, capacitor body is carried out vacuum drying treatment, removes metallic film capacitor fuse thin film sky between layers
Gas impurity, is shunk by rational, makes capacitor body thin film even closer between layers；4th step, at vacuum drying
Fuse after reason carries out DC break down voltage and the dual test of ac voltage withstanding, effectively eliminates internal flaw point；5th step, by test passes
Fuse, by copper foil soldering connect capacitor case exit.
Comprehensive above feature, a kind of DC filter capacitors fuse processing technology completes after capacitor, can meet
Security performance can meet life requirement again.
