Description
Technical field
The present invention relates to capacitor metallized film materials, particularly relate to a kind of metallizing safety membrane used in capacitor electricity
The improvement of electrode structure.
Background technology
In existing metalized film technology significant drawback be medium basement membrane during electrode evaporation, accept metal steam
During the high temperature of vapour, high-velocity molecular precipitation, sustain damage, make the work field intensity (or claiming proof voltage) of medium be substantially reduced.
Another significant deficiency is that metalized film adds the connection of webbing and metal spraying and belongs to weak link, limits impact resistance electric current and work longevity
Life.And these problems be there is no essence solution.
It is known it addition, utilize metal metallized safety membrane technology to improve the effectiveness of electricity weak point breakdown spontaneous recovery in capacitor.
Metallizing safety membrane used in capacitor electrode structure, is that the metallization the narrowest gap strip of coating electrode being deposited with on medium is divided
Being divided into various fritter electrode units, each small electrode unit has had small coating fillet and the electric capacity of fuse effect
Device overall electrode is connected, and time on the film of this structure if any electricity weak point breakdown, disruptive discharge electric current can little this place
The coating fillet connected outside electrode unit block blows, and breakdown current is extinguished, and makes the small electrode unit with breakdown point with overall
Capacitor cut off, reach spontaneous recovery, though and integral capacitor device have lost the capacitance being isolated small electrode unit, can maintenance
Normal work, so that capacitor improves running voltage and service life.It there is also shortcoming: first, punctures and oneself when having
When more giving birth to, though the capacitance being isolated small electrode unit is the least, area about 50mm2, but with puncture spontaneous recovery point face normally
Long-pending 0.5mm2Comparing, differ hundreds of times, so often making peace membrane capacitance in spontaneous recovery is tested, capacity loss values is than common metal change
Membrane capacitance standard index value is great many times, it is impossible to qualified by this examination criteria.Second, small electrode cell block there is voltage
When puncturing, though there being the coating fillet of outer company to play fuse protection, but the many outer coating connected not being blown under normal work is narrow
Bar, they are gathered when flowing through by the charge/discharge operation electric current of capacitor, and around current density ratio, electrode abruptly increase is a lot, makes coating narrow
Bar becomes heat generating spot, owing to heating necessarily reduces dielectric withstanding voltage, thus reduces the media operation field intensity of capacitor.And make metal
The overall equivalent series resistance of polarizing electrode increases to 2 to 3 times, depending on the direction of small electrode cell block (as shown in Figure 6).
Summary of the invention
It is an object of the invention to overcome the above-mentioned deficiency of existing safety diaphragm technology, it is provided that the improvement of a kind of safe film electrode
Design, eliminates gap strip and the coating fillet of the spaced electrodes unit bringing the heating side effect that heats up, but also can make capacitor
The power on effectiveness of weak point breakdown spontaneous recovery of middle safety diaphragm obtains Reliable guarantee, and the capacity loss values that spontaneous recovery punctures will not increase；
The media operation field intensity simultaneously solved in the metalized film evaporation course of processing by this improvement reduces problem, and metalized film
The impact resistance electric current of capacitor and working life problem.
The technology used in the present invention design is:
The electrode structure of a kind of metallizing safety membrane used in capacitor, for plating zinc/aluminum metal on polypropylene media basement membrane
Layer electrodes constitutes compound film strips, it is characterised in that the dual-side of compound film strips is formed respectively with upper continuous print functional bands, institute
The functional bands side stated be stay limit, opposite side without coating be that coating adds webbing；Limit and the gold adding between webbing is stayed described
Belong to coating electrode structure and there is the lateral clearance bar that make that longitudinally isolation is used a plurality of is parallel to each other, spacing is equal；And adjacent horizontal stroke
Electrode between gap strip is the continuous coating electrode in working area, does not has longitudinal void as conventional security film in this region
Row culture isolation is used, and has also abolished the coating fillet being used as fuse；
The continuous coating electrode in working area between described adjacent transverse gap strip is characterised by thickness of coating, is common
The 1/2 to 1/5 of metalized film thickness of electrode, namely the sheet resistance of coating is 15 Ω/～40 Ω/；This layer electrodes is thick
Degree make trapezoidal profile in the horizontal, with add webbing adjacent the thickest (sheet resistance of coating is 15 Ω/about), with stay
Limit adjacent the thinnest (sheet resistance of coating is 40 Ω/about)；It is 2 Ω/～4 that thickness of coating reaches metal surface resistance
Ω/, adding webbing to the transition width of the thickness of coating of working area electrode is 5～7mm.
Described work longitudinally isolate the lateral clearance bar being used be characterised by all lateral clearance bars be parallel to each other, spacing
Equal, orientation and film strips laterally between angle be 6 °～10 °, its spacing value 10mm～60mm (preferably 20mm～30mm), its
Width value 0.15mm～0.5mm (preferably 0.2mm～0.3mm), length adapts with film strips width so that it is one end with stay limit phase
Logical, the other end intersects with adding webbing, deeply adds webbing about 0.8mm；
The electrode structure of the described metal metallized safety film with the isolation of lateral clearance bar, it is characterised in that described symmetry
When stacking rolls capacitor element, stay limit and the coating of upper layer film S and lower membrane X add the interlaced correspondence of webbing, i.e. coating
Add webbing and transition region and another floor stays limit corresponding with coating Bao district.So can ensure any portion of the medium of capacitor
In two electrodes up and down of position, always having an electrode is relatively thin electrodes, reaches the safe spontaneous recovery punctured.
Described staying limit with to add webbing identical with common metal film, the hem width degree that stays without coating is 1.5mm～2.5mm；
It is 2mm～3mm that coating thickeies hem width degree,
The technical solution adopted in the present invention, takes the corrective measure of innovation in the design, and has problems with
Good technique effect:
1., in the technical solution adopted in the present invention design, do not use gap strip separate metal plating as conventional security film
Layer becomes electrode junior unit, does not use the coating fillet protection as the weak point breakdown that powers on basement membrane of fuse effect, and plays
Metallization coating to electricity weak point breakdown intrinsic self-healed protection function, i.e. medium power on weakness breakdown time, breakdown point is adjacent
Layer electrodes can breakdown electric current energy fusing vapor away, formation area≤0.5mm around breakdown point2Blank
Circle, is dielectrically separated from breakdown point, makes puncturing of capacitor reach spontaneous recovery, and keeps normal work, and capacity loss values ratio passes
The capacitance loss that the breakdown protection of system metallized safety film capacitor causes reduces hundreds of times.
2. though Technical Design does not use the protected mode of conventional security film, but non-security to common metallization
In membrane capacitance, electricity weakness the problem of effective spontaneous recovery can not have employed special measure sometimes, and this measure is thinning capacitor working area
The thickness of layer electrodes, reaches the 1/2 to 1/5 of common metal safety diaphragm, hits so that puncturing in self-healing procedure for vaporing away
Wear the insulation of a coating formation around energy needed for blank coil and be reduced to original more than 1/3, to reach not injure breakdown point
Surrounding medium and the purpose of safe spontaneous recovery.
3. and layer electrodes thickness makees trapezoidal profile in the horizontal, exchange the electric current density of charge and discharge operating current with capacitor
Be distributed consistent the most in echelon, thick at the big local coating of electric current density, resistance is little, with reduce capacitor loss and
Caloric value.
4. the technical program design in use thinning capacitor working area layer electrodes thickness 1/2 to 1/5 another dash forward
Go out advantage, be the work field intensity that improve metalized film.Because medium basement membrane is during electrode evaporation, the knot that coating is thinning
Really, basement membrane accepts the high temperature of metallic vapour, the quantity of high-velocity molecular precipitation reduces, and the degree sustained damage during evaporation is also
Considerably reduce, make the work field intensity of medium obtain and significantly improve.Due also in the technical program design not as conventional security film that
Sample longitudinal void bar and be used as the coating fillet of fuse, eliminate the additional heat generating spot produced because of this structure and
The heating of additional equivalent series resistance, also makes the work field intensity of medium obtain and improves.So the product of this programme design is one
Plant the metal metallized safety film with high workload field intensity electrode structure.
5. the technical program design is not the most continuous print at Liu Bian and the coat of metal electrode added between webbing, and
A plurality of be parallel to each other, lateral clearance bar isolation segmentation that spacing is equal.It practice, in capacitor under alternate current operation, hand over
The sense of current of stream discharge and recharge connects limit to staying edge direction stream from metal spraying, namely the work sense of current of discharge and recharge and metal
Change the laterally uniform of film, parallel with lateral clearance bar, therefore the running current of capacitor is not acted as by lateral clearance bar
With；But once the quality that webbing is connected with the contact of metal spraying that adds of somewhere layer electrodes exists and weakens, and has bigger contact electricity
Hinder and generate heat, or in the case of capacitor-end somewhere occurs localized corona electric discharge, or capacitor is by greater impact electric current
Time, making to add at this webbing and be connected with the contact of metal spraying and completely disengage from, damage the former road of operating current in district obstructed, the flow direction must
Make fore-and-aft tilt, transfer of changing its course, flow to damage the most unspoiled bonding pad that contacts adding webbing and metal spraying of both sides, district, thus increase
Add and contacted, with damage district adjacent, the electric current density and temperature rise connected, and and then damaged, made damage district extend to both sides.Expanding
During exhibition, damage region electrode area and corresponding transfer current increases therewith, make what adjacent contact connected breakdown speed add
Hurry up, enter vicious cycle, this is an important damage mechanism about capacitor life-span the most unheeded.And the technical program
In electrode structure be not the most continuous print, but a plurality of be parallel to each other, lateral clearance bar isolation point that spacing is equal
Section, vertical transfer current blocking, makes this reduction damage and is placed restrictions between two adjacent lateral clearance bars, not to both sides
Add webbing to spread with metal spraying bonding pad.This to add webbing contact with metal spraying connection damage district restriction protection, make capacitor
Impact resistance electric current and working life there has also been raising.
