Description
Technical field
The present invention relates to thin film capacitor manufacturing metallized film materials, more particularly to a kind of more interior string structures
Metallized film.
Background technology
For thin film capacitor because it is used widely with good resistance to pressure and self-healing property, metallized film is thin-film electro
The important materials of container production manufacture, by high purity metal（Such as AL, ZN）It melts, evaporate under high vacuum state, being deposited to Jie
On matter basement membrane, the film after medium membrane surface forms one layer of very thin coat of metal is exactly metallized film；Metallization electricity
Power capacitor is generally used in low-voltage power grid of the voltage no more than AC1000V, to use in high voltage (AC2000V
More than) or voltage jump is frequent or the serious occasion of overcurrent is used as the metallization AC capacitor of compensation, domestic manufacturer is general
All over the method using conventional power capacitor external series, single thin film capacitor core is made in common metal film first
Then several single thin-film capacitor cores are together in series and are processed into integral capacitor device by son.It is manufactured with this design and processes
Capacitor not only take a lot of work material, and since manufacturing procedure is more, the high failure rate of product, although by several single thin film capacitors
Voltage class can be improved after outside core series connection, but is difficult the current density for reducing single capacitor body metal spraying end face,
To cause capacitor to generate heat, and the capacitor body being together in series differing in size due to capacitance, it is easy to because of electricity
Pressure, which is unevenly distributed, causes integral capacitor device to puncture.
Invention content
The purpose of the present invention is being directed to the deficiencies in the prior art, provide it is a kind of it is more in string structure metallized film,
And using the Metallized power capacitor of its manufacture, cost-saved, the failure rate of product is low.
Technical solution
To achieve the above object, present invention employs following technical schemes：String structure metallized film in more, including through cutting machine
The first metallized film and the second metallized film formed after cutting；First metallized film, the second metallization are thin
Film is both provided with wide metal coated strip, narrow metal coated strip, is respectively provided between the width metal coated strip and narrow metal coated strip
There is blank isolation strip.
Further, must be matched when wound capacitor is laminated in first metallized film and the second metallized film makes
With.
Further, first metallized film and the second metallized film include at least 1 wide metal coated strip.
Further, when constituting string structure in even number, first metallized film is without narrow metal coated strip, and described the
Two metallized films include 2 narrow metal coated strips.
Further, when constituting string structure in odd number, first metallized film is wrapped with the second metallized film
Containing 1 narrow metal coated strip.
Further, the sum of the wide metal coated strip quantity of first metallized film and the second metallized film adds 1
Constitute equivalent interior string number inside the Metallized power capacitor of manufacture.
Further, when constituting string structure in even number, it is thin that the first metallized film width is less than the second metallization
Film width 3mm or so, when constituting string structure in odd number, first metallized film and the stacking of the second metallized film are wound
Longitudinal misalignment 3mm of palpus or so when capacitor, it can be ensured that the metallic particles sprayed when capacitor body both ends of the surface metal spraying will not cause
Constitute the power-on and power-off short circuit of polar of capacitor.
Further, the blank isolation strip replaces traditional blank to stay sideband.
Preferably, the wide metal coated strip is 2 times of narrow coat of metal bandwidth.
Preferably, blank isolation strip width is 2mm or so.
Compared with prior art, the present invention haing the following advantages：
1. use Metallized power capacitor produced by the present invention, it is internal it is equivalent connect at more capacitors, without will be common
Single thin-film capacitor core is made in metallized film, and then several single thin-film capacitor cores are together in series, and it is whole to be processed into
Bulk capacitor, it is not only cost-saved, reduce manufacturing procedure, the failure rate of product is low.
2. using Metallized power capacitor produced by the present invention, due to equivalent at internal more capacitors series connection, reduce
Capacitor body metal spraying end face quantity, avoids the current density of single capacitor body end face greatly to cause capacitor to send out
The problem of heat.
3. Metallized power capacitor produced by the present invention is used, it is equivalent due to equivalent at internal more capacitors series connection
The capacitor body capacitance being together in series it is equal in magnitude, voltage's distribiuting will not be caused uneven and integral capacitor device is caused to hit
It wears.
