Technical field
The present invention relates to a kind of preparation method of supervoltage CBB four-string noninductive capacitor.
Background technology
In electronic product, the capacitor electronic device that is absolutely necessary, wherein the metallized polypropylene film capacitor has been widely used in the various electronic and electrical equipments such as display device, stereo set, audio-visual equipment, the communication apparatus, data transmission and processing.And existing in the market this type of capacitor generally has relatively poor, the defective such as cost an arm and a leg of little, the heat-resisting high voltage performance of capacity, and has the danger of partial discharge.In addition, the thickness of the capacitor coat of metal is very big to the capacitor performance influence, and the thin more disruptive field intensity of coating is high more, and the energy that is produced during self-healing is low more.But coating is thin more, and metal spraying part in element end is big more with the contact resistance at coating edge, and under the effect of inrush phenomenon, the contact resistance heating can cause capacitance to descend, and loss increases.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of preparation method of supervoltage CBB four-string noninductive capacitor, and bigger, the heat-resisting high voltage performance of the noninductive capacitor capacity of preparing is stronger, coefficient of safety is higher.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of preparation method of supervoltage CBB four-string noninductive capacitor is characterized in that preparation process may further comprise the steps:
(1) selects high-quality polypropylene film material for use, zinc-aluminium base material micro materials is coated in the polypropylene film surface equably, make required metallized film; Then metallized film is carried out vapor deposition treatment: a film adopts steaming three to stay two mode, and one side then adopts steaming two to stay three mode in addition, steams three and stays two to be meant three places of evaporation on the film, and two equidistant empty limits are reserved in the centre; Steaming two stays three to be meant two places of a film evaporation, and two places of evaporation and steam three and stay two empty limit just in time corresponding, reserve three equidistant empty limits and stay three local correspondences of two evaporations again with steaming three, the overlapping back of the winding film that such two evaporations are good forms four equivalent capacitors in series;
(2) high molecular accumulation is carried out in the metallized film marginal portion that vapor deposition treatment is crossed, and forms and the intact layer of metal layer that contacts of outside metal spraying material;
(3) overlapping coiling is carried out on the metallized film two sides after the high molecular accumulation, formed the capacitor of one four string, make a complete capacitor the inside form, play the effect of dividing potential drop by the capacitors in series that 4 capacity equate;
(4) with metal spraying material with the spraying of the surface of capacitor, with big electric current CP wire or tinned wird are dissolved in the metal end face of capacitor again, make it intact contact, then the electrode of capacitor is drawn;
(5) last sealed at both ends with capacitor again can make required capacitor.
As preferably, to adopt and steam three metallized films that stay two mode vapor deposition treatment to cross, side's resistance is 3.5～4.0; Adopt and steam two metallized films that stay three mode vapor deposition treatment to cross, side's resistance is 5.0～5.5.
As preferably, described metal spraying material is that tin, antimony, copper, zinc quaternary close element.
As preferably, described zinc-aluminium base material is coated in the polypropylene film surface with the vacuum static electricity cladding process.
As preferably, epoxy sealing is used at the two ends of described capacitor.
It is primary raw material that the present invention adopts high-quality polypropylene film material and zinc-aluminium base material micro materials, vacuum static electricity applies and forms, and the evaporation structure by optimizing metallized film and its edge is carried out high molecular accumulation handle, improve its service behaviour and avoid the problem of partial discharge.The supervoltage CBB noninductive capacitor high-frequency loss of the present invention's preparation is little, the loaded current ability is strong, inductance value is low, in addition, this kind capacitor also has the advantage of insulation resistance height, long service life, be applicable to the high voltagehigh frequency environment, be particularly useful for electronics electric billy energy storage high-voltage capacitance, voltage is more than 10,000 volts.
