Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, the capacitor transformer that the present invention is new, including four layers of primary conductive film 3 being arranged side by side, adjacent two Two layers of secondary electrical film 9, a total of six hierarchical levels conducting film 9, adjacent two layers conducting film are provided with side by side between layer primary conductive film 3 Between be provided with insulating dielectric layer 6;One end phase of the one end of primary conductive film 3 in odd-level with the first current limliting insurance 2 Connection, the one end of one end of the primary conductive film 3 in even level with the second current limliting insurance 10 is connected, in odd-level Primary conductive film 3 connects one end of the first current limliting insurance 2 and the primary conductive film 3 in even level is connected the second current limliting insurance 10 One end set in the same direction;The other end of first current limliting insurance 2 is connected with a terminals of power input 1, and the second current limliting is protected 10 other end of danger is connected with another terminals of power input 1;First layer secondary electrical in all secondary electrical films 9 Film, the 4th hierarchical level conducting film and layer 5 secondary electrical film away from the first current limliting insurance 2 one end respectively with resistor 7 one End connects, and forms the first contact;Second layer secondary electrical film, third layer secondary conducting film in all secondary electrical films 9 and Six hierarchical level conducting films connect away from the other end of the one end of the first current limliting insurance 2 respectively with resistor 7, form the second contact, First contact is connected with a terminals of power output end 8, another terminals phase of the second contact and power output end 8 Even;First current limliting insure the 2, second current limliting insurance 10, resistor 7, all primary conductive films 3, all secondary electrical films 9 with And all insulating dielectric layer 6 are closed in electric field shielding layer 5, electric field shielding layer 5 is coated with shell 4, and power supply is defeated Two terminals of two terminals and power output end 8 that enter end 1 are respectively positioned on outside shell 4.
Shell 4 is made of insulating resin.Insulating dielectric layer 6 can need to be made of different dielectrics according to different. Electric field shielding layer 5 is made of aluminium foil, copper sheet or iron sheet.
, can be the conductive film layer of excision forming when making capacitor transformer of the present invention(Aluminium foil)With dielectric layer(Wax Paper), after the discharge of interval, it is pressed into transformer body inner bag.Reserve in advance input tie point, output end tie point and Current limliting insures and resistor, after mode as shown in Figure 1 is coupled well, with electric field shielding layer(Aluminium foil or copper sheet, iron sheet etc.) Wrap up, form electric field shielding layer 5.Finally with insulating resin in the appropriate mould of size, pouring molding.
During using capacitor transformer of the present invention:Power input 1 is directly accessed civil power, will be in input primary conductive An alternating electric field is formed between film 3, and output end secondary electrical film 9 is just bathed in this alternating electric field, and then formed New alternating voltage, the output current then needed in power output end 8.The transformer can also be arranged on mobile phone, In the electrical equipment such as LED lamp, civil power is directly accessed, other no longer external transformers.
The output voltage of this capacitor transformer depends on relative position of the conducting film in electric field, i.e. adjacent two layers conducting film The distance between.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;Output end resistor in parallel Resistance, can all considerable influence be produced to output current and voltage.These characteristics can when manufacturing, according to different needs, Manufacture the special transformer of different requirements.In theory, if distance is equal between each conductive film layer(0.3mm), and insulation dielectric Homogeneous is without electric field isolation effect(Papery is dried), civil power 220V can be in the conductive intermembranous acquisition 100V of output or so voltage.(Without simultaneously During the leak resistance of connection)
In experiment, aluminium foil conducting film 0.06mm, papery dielectric 0.3mm, total induction area(It is single that four layers of conducting film form one Position induction area)When 1dm2, leak resistance 1M Ω, output voltage 3V, output current 0.5mA.
Capacitor transformer of the present invention can only reduce voltage, it is impossible to raise voltage.
Mutual inductance effect of the capacitor transformer of the present invention using multi-layer conductive in electric field, in the intermembranous shape of output end secondary electrical Cheng Xin voltage difference, during this voltage difference constantly release, form output current.Multilayer electric conductor is superimposed, and compresses transformation Body accumulates.Again due to zero line electric field(Input zero line voltage-to-ground is 0)Introducing(Civil power do not differentiate between it is positive and negative, it is only fiery Line and zero line, live wire and zero line are also seldom distinguished in electricity consumption --- two plugs can be with any insertion in directionless ground!Also It is to say:Any one port of power input is live wire, then another port, necessarily zero line.Only using old-fashioned Zero line and live wire are just distinguished during capacitor type transformer, and is not only had using zero line as a port for forming current path Make full use of the security and " extension " influence on live wire electric field in the electric field that zero line voltage-to-ground is 0.)Increase electric field effect Should, the low pressure over the ground of output voltage can be kept, input power is nonpolarity(Power input needs not distinguish between zero line and fire Line)And transformation is abundant effective, and then improve the power output and security of transformer.Simultaneously in an output end leakage in parallel Resistance, can make the voltage of output end turn into effective voltage, also increase the capacitive reactance of the interpolar of input two in transformer.So that The capacitive character leakage effect that no-load transformer will not be also formed between input the two poles of the earth, improve security.Power input is set Two current limlitings insurances, once any insulating dielectric layer 6 is electrically shocked and worn in transformer, power input 1 will form one Leaky capacitor, input electric current moment increase, and blow current limliting insurance, it is ensured that transformer leakproof.
Utilize the distance relation and the dielectric property of the insulation dielectric of unlike material between each conductive film layer, electric capacity of the present invention The voltage of KV level can once be depressured to ten volts of voltages by transformer.
Can be as needed, it is variously-shaped that this capacitor transformer is fabricated to cylinder etc..If only require direct current output (Such as charger), rectification circuit is solidificated in the transformer module can also 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 easy to modularization to mass produce.This Invention capacitor transformer coordinates existing low-power consumption electrical appliance, is designed with new way, realizes transformer cost, body Product, power consumption, safe and environment-friendly perfect unity.
