Description
Technical field
The utility model relates to a kind of medium-high frequency small inductor air core reactor, belongs to reactor technical field.
Background technology
Along with developing rapidly of converter technique, the medium-high frequency power supply be widely used in Modern Electrical Drive, Electric control field more and more plays an important role.Utilize three-phase thyristor bridge rectification circuit to be direct current by power frequency electric rectification in medium-high frequency power supply, realize Electric Drive through being reverse into medium-high frequency power supply and controlling motor, in medium-high frequency loop, using reactor mainly to play filtering and power factor compensation effect.In current domestic industry, widely used medium-high frequency reactor adopts water-cooled structure, and winding is copper pipe coiling, logical cooling pure water in pipe.Because the winding conducting wire cross section of this structure is relatively little, produces a large amount of heats during work, both caused energy waste, make again device efficiency reduce.In addition because cooling line is longer, caliber is thin, causes the cooling water outlet and inlet temperature difference large, works long hours very easily to block current at in-tube fouling and thread a pipe, and winding is burnt because of overheated.
Utility model content
The purpose of this utility model is: for the defect of prior art, proposes a kind of reactor with features such as small size, low noise, high efficiency, non-maintaining and life-span are long to substitute traditional Water-cooled reactor.
The technical scheme that the utility model adopts is: a kind of medium-high frequency small inductor air core reactor, comprise supporting structure, coil and copper bar, supporting structure is provided with coil, and the appearance of coil is provided with copper bar, described coil adopts the coiling of multiply enamelled stranded-wire to form, and establishes and use heat dissipation channel between encapsulating.
In the utility model: described supporting structure comprises support, stay, upper head plate and bottom plate, upper head plate and bottom plate are set in the fluting inside stay, upper head plate and bottom plate center are respectively equipped with centre bore one and centre bore two, and the two ends of support are fixed respectively by centre bore one and centre bore two.
After adopting technique scheme, the beneficial effects of the utility model are:
(1), coil adopts the coiling of multiply enamelled stranded-wire to form, and establishes with heat dissipation channel between encapsulating, can according to operation needs, and increase area or the radical of enamelled stranded-wire, coiling is convenient, good heat dissipation, overall structure safety and stability;
(2), good heat-sinking capability, so overall structure is self cool, low noise, energy-conserving and environment-protective, conventional highfrequency reactor winding is copper pipe coiling, logical cooling pure water in pipe, because the winding conducting wire cross section of this structure is relatively little, produces a large amount of heats during work, both caused energy waste, device efficiency is made again to reduce, in addition because cooling line is longer, caliber is thin, causes the cooling water outlet and inlet temperature difference large, normal time service very easily blocks current and threads a pipe at in-tube fouling, winding is burnt because of overheated.
