Abstract
The invention discloses a totally-enclosed magnetic tank for a reactor and a transformer. The totally-enclosed magnetic tank for the reactor and the transformer consists of two soft magnetic half tanks which are molded by virtue of integral die casting, wherein the centers of the two soft magnetic half tanks are provided with button stems; after the soft magnetic half tanks are butted, the shells of the two soft magnetic half tanks and the button stems jointly form a magnetic conductive loop; electric induction coils are wound at the outer sides of the button stems; the two soft magnetic half tanks are locked by virtue of a bolt; and side outlet grooves are reserved on the soft magnetic tanks. By the totally-enclosed magnetic tank for the reactor and the transformer, the technical problems that as the coil is exposed outside a magnet, the conventional powder metallurgic soft magnetic powder core inductor and transformer cannot be used for the occasions with high capacity and higher magnetic leakage requirements and the like are solved.
Description
Technical field
The present invention relates to the improvement technology of electric equipment products such as reactor that a kind of high-frequency current occasion uses, transformer.
Background technology
At present, in the production of powder metallurgy soft magnetic-powder core inductor and transformer, prior art is on the ferrocart core of annular or square assembly unit iron core, to coil, and coil exposes outside magnet, can't ensure Electro Magnetic Compatibility and leakage field size.Traditional powder metallurgy soft magnetic-powder core inductor and transformer are mainly used in high frequency precision circuit and low power electric power, electron trade.When using in big capacity and occasion that leakage field is had higher requirements, product must with to keep certain electric insulation distance all around.
Summary of the invention
The object of the present invention is to provide a kind of totally-enclosed magnetic jar that is used for reactor, transformer; To solve traditional powder metallurgy soft magnetic-powder core inductor and transformer; Because coil exposes outside magnet, and the technical problems such as occasion that can not be used in big capacity and leakage field is had higher requirements.
The present invention realizes above-mentioned purpose through following technical proposals:
A kind of totally-enclosed magnetic jar that is used for reactor, transformer; It is made up of for half jar two one die cast soft magnetisms; The center belt carcass post that these two soft magnetisms are half jar after half jar of butt joint of described soft magnetism, together constitutes magnetic conductive loop by the shell and the described stem stem of half jar of two soft magnetism; Around inductance coil, with half jar of locking of two soft magnetisms, the soft magnetism jar leaves side and goes out wire casing through bolt in the stem stem outer felt.
Said two soft magnetisms are circular for half jar, and said bolt passes the locking of accomplishing half jar of two soft magnetism in stem stem.
Go out in the wire casing in soft magnetism jar side, fill colloid with insulating property (properties).
The present invention has following advantage: mainly solved the closed magnet circuit problem of powder metallurgy soft magnetic material, adopted the totally-enclosed pot type structure of having only side outlet opening to make and realize little leakage field, low-loss and compact structure with reactor, the transformer of its manufacturing; Simultaneously, the design of pot type has solved quick manufacturing and has assembled the production problem flexibly, makes the production of reactor and transformer more easy, has made things convenient for design, manufacturing and the organization of production of reactor and transformer production enterprise.
Description of drawings

Fig. 3 is the perspective view of first jar of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Referring to Fig. 1, the present invention forms totally-enclosed die cast soft magnetism jar by half jar 1 of two one die cast soft magnetism, 2.Center in half jar 1 of two one die cast soft magnetism, 2 is provided with stem stem 6, constitutes magnetic conductive loop by the shell and the stem stem 6 of magnetic jar 1,2.Half jar 1 of two soft magnetism, 2 structural representation are referring to Fig. 2,3.
What present embodiment provided is the one die cast soft magnetism jar 1,2 of annular.With described circular one die cast soft magnetism jar 1,2, through bolt 3 pass fixing hole 5 up and down the locking that is harmonious of one die cast soft magnetism jar cover, leading-out terminal leaves out wire casing 4, then with nut check, forms totally-enclosed die cast soft magnetism jar.It is inner to put into totally-enclosed die cast soft magnetism jar at whole coil again, goes out the colloid that filling has insulating property (properties) in the wire casing 4 in soft magnetism jar side, is used to make soft magnetism jar magnetic conductive loop reactor or power transformer product.
The present invention can also adopt the magnetic jar and other fixing modes of other shapes, and the foregoing description is not the qualification to technical scheme of the present invention.
The present invention mainly should be in the manufacturing field of the powerful reactor of all kinds of high, medium and low frequencies, transformer.
