Embodiment Construction

[0018] Concrete structure of the present invention is referring to accompanying drawing. The components made of soft magnetic powder metallurgy include a semicircular bottom plate, a magnetic ring shell and a magnetic column, which are assembled to form an assembled soft magnetic tank-type foil-wound single-phase reactor with a built-in foil coil in the tank shell. Soft magnetic powder metallurgy iron powder tank parts are made of iron powder or sendust material through pressure processing.

[0019] Depend on figure 1 , 2 It can be seen that the reactor as a whole is composed of a magnetic core 3, a magnetic ring shell (shielding wall) 2, upper and lower bottom plates 1, 5 to form a magnetic tank. The foil winding coil is put into the magnetic tank, and the whole magnetic tank is locked through the bolt 6 through the fixing hole 4 to complete the composition of the soft magnetic reactor. The height and design capacity can be adjusted freely by adopting the segmented structu...

Abstract

The invention discloses an assembled single-phase reactor. A shell of a magnetic pot is formed by assembling two semicircular base plates positioned at two ends and a plurality of magnetic ring housings positioned between the two semicircular base plates; the shell of the magnetic pot and magnetic columns which are positioned in the magnetic ring housings and magnetically communicated with the two semicircular base plates together form an assembled magnetic pot; the magnetic columns are a plurality of series assembly structures; the shell of the magnetic pot and the magnetic columns are fixed with each other through passed bolts; one or two gaps for leading out wires is or are formed in the plurality of magnetic ring housings; foil winding coils are wound outside the magnetic columns; and a filling material is filled in a space in the pot body. By the assembled single-phase reactor, the technical problems that the conventional single-phase reactor product made of soft magnetic powder metallurgy materials and foil winding coils is low in electromagnetic compatibility and high in magnetic flux leakage, cannot change the capacity and the technical characteristic of the product conveniently, and the like can be solved.

Description

technical field [0001] The invention relates to a single-phase reactor product suitable for high-frequency current use made of a soft magnetic powder metallurgy material and a foil-wound coil, specifically an assembled soft magnetic powder metallurgy iron powder tank foil Winding single-phase reactor products. Background technique [0002] For powder metallurgy iron powder core single-phase reactors used in high-frequency precision circuits and low-power electronics industries, the traditional production method is to wind a coil on a simple circular iron powder core. The disadvantage is that the coil is exposed outside the magnet, and the product capacity and technical characteristics cannot be easily changed, and the capacity is small and the magnetic flux leakage is large. Contents of the invention [0003] The purpose of the present invention is to provide an assembled single-phase reactor to solve the problems of poor electromagnetic compatibility, inability to change...
