The inversion inductor comprises an iron-based amorphous alloy magnetic core, wherein a copper coil is wound on a primary winding in a clockwise manner, and a copper coil is wound on a secondary winding in an anticlockwise manner; each copper coil is coated by an insulating tape to form a coil bag; teflon insulation sleeves are sleeved outside connectors of the copper coils; and an insulating paper board is arranged between each coil bag and the magnetic core. The inversion inductor has the advantages of unique structure, advanced technology, superior electrical performance, reduced power loss, and greatly improved power conversion efficiency.
Description
Technical field
The utility model relates to the used inversion inductor of a kind of solar energy power generating.
Background technology
Inverter is claimed feed regulator isolator again; According to the purposes of inverter in photovoltaic generating system can be divided into the self power supply with and be incorporated into the power networks with two kinds; Main operation principle: inverter is a kind of electric power adjusting device of being made up of the IGBT semiconductor device, is mainly used in and converts direct current power to alternating electromotive force.Generally constitute by boost loop and inversion bridge type return.(BOOST) loop of boosting boosts to the required direct voltage of inverter output control to the direct voltage of solar cell; Inversion bridge-type (INVERTER) loop then converts the direct voltage after boosting to the alternating voltage of conventional frequency of equal valuely.
Solar cell is on the high side at present, in order to utilize solar cell to greatest extent, improves system effectiveness, must manage to improve the efficient of inverter.The operation principle of whole inverter circuit mainly is to change through the IGBT semiconductor device, and the efficiency losses of inverter has three aspects, the 1.IGBT semiconductor device; 2. inductance component; 3. capacitor element, wherein the efficiency losses of inductance component is maximum, needs to improve structure and manufacture craft; Improve the reliability and the Electro Magnetic Compatibility of inductance component, reduce power loss.
The utility model content
The utility model provides solar energy power generating used inversion inductor, and its structure is unique, and technology is advanced, has good electric property, has reduced power loss greatly.
The inversion inductor that a kind of solar energy power generating of the utility model is used; Comprise the magnetic core that Fe-based amorphous alloy is made; The Fe-based amorphous alloy magnetic core is by 80%Fe and 20%Si, and the category-B metallic element constitutes, and it has high saturated magnetic induction (1.54T); The loss ratio of Fe-based amorphous alloy and silicon steel is superior to silicon steel sheet at everyways such as magnetic permeability, exciting curent and iron loss.Said inversion inductor is wound with copper coil clockwise on elementary winding; On secondary winding, be wound with copper coil counterclockwise; The copper coil outside coats with insulating tape and forms the coil bag; Said copper coil connector lug outside is with the not imperial insulating case of iron, is provided with insulating board between said coil bag and the magnetic core.
Further, said inversion inductor is outside equipped with the steel band that is used for fixing the coil bag, and steel heading end is locked at copper coil connection side top.
As a kind of improved products structure, said inversion inductor also has an aluminum shell, is filled with the heat conduction silica gel in the space in the aluminum shell, plays insulation, protection against the tide, heat radiation and fixing effect.
The utility model has following technical characterstic and advantage:
The magnetic core that adopts Fe-based amorphous alloy to make; Have high saturated magnetic induction and lower iron loss rate, reduced inversion inductor volume greatly, lowered cost of manufacture; And through coil particular structure and manufacture craft; Make the inversion inductor have good electric property, reduced power loss greatly, prolonged product useful life.

Fig. 2 is the used inversion inductor structure sketch map of solar energy power generating that the utility model embodiment two provides.
Embodiment
As shown in Figure 1; The utility model embodiment provides a kind of solar energy power generating used inversion inductor, comprises the magnetic core 1 that Fe-based amorphous alloy is made, and the Fe-based amorphous alloy magnetic core is by 80%Fe and 20%Si; The category-B metallic element constitutes; It has high saturated magnetic induction (1.54T), and the loss ratio of Fe-based amorphous alloy and silicon steel is superior to silicon steel sheet at everyways such as magnetic permeability, exciting curent and iron loss.Said inversion inductor is wound with copper coil 2 clockwise on elementary winding, on secondary winding, be wound with copper coil 3 counterclockwise, and during making, winding displacement twines closely, and it is overlapping to cross one another, and copper cash can not break skin.The copper coil outside coats with insulating tape and forms the coil bag, prevents that coil is loose, carries out the shaping of coil bag again, operations such as the pairing of left and right sides coil bag, scolding tin.Said copper coil connector lug outside is with the not imperial insulating case 4 of iron, is provided with insulating board between said coil bag and the magnetic core.
Further, said inversion inductor is outside equipped with the steel band that is used for fixing the coil bag, and steel heading end 5 is locked at copper coil connection side top.
As shown in Figure 2, as a kind of improved products structure, said inversion inductor also has an aluminum shell 6, is filled with the heat conduction silica gel in the space in the aluminum shell, and the inversion inductor is connected with external circuit with red leading-out terminal 8 through black end of incoming cables 7.
The magnetic core that the utility model adopts Fe-based amorphous alloy to make; Have high saturated magnetic induction and lower iron loss rate, reduced inversion inductor volume greatly, lowered cost of manufacture; And through coil particular structure and manufacture craft; Make the inversion inductor have good electric property, reduced power loss greatly, prolonged product useful life.
Above disclosedly be merely a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, the equivalent variations of therefore being done according to the utility model claim still belongs to the scope that the utility model is contained.
