Description
technical field:
The present invention relates to capacitor technology field, particularly a kind of novel capacitor metallized film.
background technology:
Existing metallic film capacitor, at membrane surface even evaporation layer of metal layer, edge thickeies one deck once again, have the following disadvantages: (1) is withstand voltage high product, because coating is thinner, bear ripple current scarce capacity, and product in use easily oxidation cause product capacity decline, loss rise; (2) bear the product that ripple current ability is strong, because coating is thicker, self-healing ability is poor, causes that product is resistance to be forced down.Existing metallic film capacitor presses resistance to and bear in ripple current ability and can not get both, and there is inverse ratio phenomenon, withstand voltage higher, and it is poorer to bear ripple current ability; Otherwise, better.Existing withstand voltage high product coating is generally zinc-aluminium simultaneously, and sheet resistance is generally at 30 more than Ω, and coating is thin, is very easily oxidized, and causes product premature failure.
summary of the invention:
The object of the invention is to overcome above deficiency, relating to a kind of novel metal film for making capacitor, thus make product have withstand voltage height simultaneously, to bear ripple current ability strong, and the advantage such as not oxidizable.
Object of the present invention is achieved through the following technical solutions: a kind of novel capacitor metallized film, comprise basement membrane and metal level, on basement membrane, evaporation has metal level, metal level is aluminium lamination, zinc layers or allumen layer, and the limit, one end of the Width of basement membrane is provided with the clear area of non-metal cladding, and the width of described clear area is 2-4mm, metal level is made up of region 1, region 2 and region 3 according to sheet resistance value size, region 1 is thickened area, edge, and width is 3 ~ 10mm, and sheet resistance value is 3-8 Ω; Region 2 is low square resistance district, and width is 1/4 ~ 1/2 of basement membrane overall length, and sheet resistance value is 4-20 Ω; Region 3 is high square resistance district, and sheet resistance value is greater than 10 Ω; And on a metallized film, region 3 sheet resistances >=region 2 sheet resistances >=region 1 sheet resistance, sheet resistance value presents stepped.
The advantage that the present invention compared with prior art has:
1, this staged evaporation mode, thickened area, edge 2-1 is wider than the thickened area of conventional evaporation mode, and sheet resistance is lower, so equivalent series resistance is little on electrode is drawn, the loss of product is little;
2, this kind of structure capacitor core that reels out, its self-healing ability, withstand voltage level determine primarily of high square resistance district, region 3, the employing fine aluminium evaporation in region 3, and coating is thin, and sheet resistance is high, and self-healing ability will be stronger, and withstand voltage will be higher;
3, this staged evaporation mode, region 1, region 2 coating all thickeies, the coat of metal on the whole resistance shows less than conventional evaporation mode, therefore product is when bearing same ripple current, heating will be less, and temperature rise will be lower, so it will be stronger that kind structure bears ripple current ability;
4, this staged evaporation mode, region 1 and region 2 are for being generally the thicker zinc-aluminium metal level of the less coating of sheet resistance, and the film of the same voltage withstand class of conventional evaporation mode is generally the thinner zinc-aluminium metal level of the higher coating of sheet resistance, zinc metal is very easily oxidized in malaria, therefore the thinner embodiment of the higher coating of sheet resistance is more obvious, so staged evaporation mode in oxidation resistance advantageously.
