Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, the capacitor transformer that the present invention is novel, comprises the four layers of primary conductive film 3 be arranged side by side, is provided with two-layer secondary electrical film 9 side by side between adjacent two layers primary conductive film 3, always have six hierarchical level conducting films 9, between adjacent two layers conducting film, be provided with insulating dielectric layer 6; One end that the one end being in the primary conductive film 3 of odd-level all insures 2 with the first current limliting is connected, one end that the one end being in the primary conductive film 3 of even level all insures 10 with the second current limliting is connected, and one end that the primary conductive film 3 being in odd-level connects the first current limliting insurance 2 is connected one end that the second current limliting insures 10 and arranges in the same way with the primary conductive film 3 being in even level; The first current limliting insurance other end of 2 is connected with terminals of power input 1, and the second current limliting insurance other end of 10 is connected with another terminals of power input 1; One end that ground floor secondary electrical film in all secondary electrical films 9, the 4th hierarchical level conducting film and layer 5 secondary electrical film deviate from the first current limliting insurance 2 connects with one end of resistor 7 respectively, forms the first contact; One end that second layer secondary electrical film in all secondary electrical films 9, third layer secondary electrical film and layer 6 secondary electrical film deviate from the first current limliting insurance 2 connects with the other end of resistor 7 respectively, form the second contact, first contact is connected with terminals of power output end 8, and the second contact is connected with another terminals of power output end 8; First current limliting insurance 2, second current limliting insurance 10, resistor 7, all primary conductive films 3, all secondary electrical films 9 and all insulating dielectric layer 6 are all closed in electric field shielding layer 5, electric field shielding layer 5 is coated with shell 4, and two terminals of power input 1 and two terminals of power output end 8 are all positioned at outside shell 4.
Shell 4 adopts insulating resin to make.Insulating dielectric layer 6 can need to adopt different dielectric to make according to difference.Electric field shielding layer 5 adopts aluminium foil, copper sheet or iron sheet to make.
When making capacitor transformer of the present invention, the conductive film layer of excision forming (aluminium foil) and dielectric layer (paraffin paper), after the discharge of interval, transformer body inner bag can be pressed into.The insurance of the input tie point reserved in advance, output tie point and current limliting and resistor, mode as shown in Figure 1 connects well, wraps up with electric field shielding layer (aluminium foil or copper sheet, iron sheet etc.), forms electric field shielding layer 5.Finally use insulating resin in the mould that size is suitable, build shaping.
When using capacitor transformer of the present invention: power input 1 is directly accessed civil power, an alternating electric field will be formed between input primary conductive film 3, and output secondary electrical film 9 is just in time bathed in this alternating electric field, and then form new alternating voltage, the output current needed then is obtained at power output end 8.Also this transformer can be arranged on mobile phone, in the electrical equipment such as LED lamp, directly access civil power, other transformers no longer external.
The output voltage of this capacitor transformer depends on the relative position of conducting film in electric field, the distance namely between adjacent two layers conducting film.Output current then depends on the area of conducting film.
In fact, the material of insulation dielectric, thickness; The material of each conductive film layer, thickness; The resistor resistance of output parallel connection, all can produce considerable influence to output current and voltage.These characteristics when manufacturing, according to different needs, can manufacture the different special transformer required.In theory, if the spacing of each conductive film layer equal (0.3mm), and insulation dielectric homogeneous is without electric field isolation effect (papery is dry), and civil power 220V can obtain about 100V voltage between output conducting film.(during without leak resistance in parallel)
In experiment, aluminium foil conducting film 0.06mm, papery dielectric 0.3mm, during total induction area (four layers of conducting film form a unit induction area) 1dm2, leak resistance 1M Ω, output voltage 3V, output current 0.5mA.
Capacitor transformer of the present invention can only reduce voltage, can not boosted voltage.
Capacitor transformer of the present invention utilizes the mutual inductance effect of multi-layer conductive in electric field, in the voltage difference that the intermembranous formation of output secondary electrical is new, in the continuous dispose procedure of this voltage difference, forms output current.Multilayer electric conductor superposes, compression volume of transformer.Again due to zero line electric field (input zero line voltage to earth is 0) introducing (civil power does not distinguish positive and negative, only has live wire and zero line, also seldom distinguishes live wire and zero line when electricity consumption---two plugs can insert arbitrarily on directionless ground! That is: any one port of power input is live wire, so another port, necessarily zero line.Only just distinguish zero line and live wire when using old-fashioned capacitor type transformer, and only using the port of zero line as formation current path, not make full use of zero line voltage to earth be the fail safe of 0 and affect " extension " of live wire electric field in the electric field.) increase field effect, the low pressure over the ground of output voltage can be kept, input power is nonpolarity (power input does not need to distinguish zero line and live wire) and transformation fully effectively, and then improve power output and the fail safe of transformer.Simultaneously in an output leak resistance in parallel, the voltage of output can be made to become effective voltage, too increase the capacitive reactance of input two interpolar in transformer.Make no-load transformer also can not form capacitive character leakage effect between input the two poles of the earth, improve fail safe.Power input is provided with the insurance of two current limlitings, once arbitrary insulating dielectric layer 6 is electrically shocked and wears in transformer, power input 1 will form a leaky capacitor, and input electric current strengthens instantaneously, blows current limliting insurance, can ensure transformer leakproof.
Utilize the dielectric property of the insulation dielectric of distance relation between each conductive film layer and unlike material, the voltage of KV level can be once depressured to ten volts of voltages by capacitor transformer of the present invention.
As required, this capacitor transformer can be made into the various shapes such as cylindrical.If only require that direct current exports (such as charger), also rectification circuit can be solidificated in this transformer module together, and then fully compress volume of transformer.
When manufacturing this transformer, just model, effect etc. are fixed up before dispatching from the factory, are convenient to modularization large-scale production.Capacitor transformer of the present invention coordinates existing low-power consumption electrical appliance, forms with brand-new patten's design, realizes the perfect unity of transformer cost, volume, power consumption, safety, environmental protection.
