Abstract
A three-phase powder metallurgy soft magnetic tank for a reactor and a transformer is characterized in that a complete closed tank type magnetic loop framework is formed by combining soft magnetic powder metallurgical parts. The complete closed tank type magnetic loop framework comprises two butted tank bodies and a three-phase core column, the three-phase core column is fixed in the two butted tank bodies, and a complete closed tank type magnetic loop is formed by the three-phase core column and the tank bodies. A coil winding is arranged at the space on the periphery of the core column in the complete closed tank bodies, and three-phase wire inlet and outlet openings are arranged on the tank bodies. The three-phase powder metallurgy soft magnetic tank for the reactor and the transformer can be used for producing products of unsaturated reactors or unsaturated transformers with small magnetic flux leakage, large capacity, low loss and high frequency.
Description
Technical field
The utility model relates to a kind of transformer, reactor technology, and the transformer that is specifically related to process with the soft magnetic powder metallurgical product, reactor are with powder metallurgy soft magnetism tank body.
Background technology
At present, in the production of powder metallurgy soft magnetic-powder core reactor, 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 is also big.Therefore, product must with to keep certain electric insulation distance all around, can't use in big capacity and occasion that leakage field is had higher requirements.Said powder metallurgy soft magnetic-powder core transformer is mainly used in high frequency precision circuit and low power electric power, electron trade.
Summary of the invention
The purpose of the utility model provides a kind of three-phase powder metallurgy soft magnetism jar that is used for reactor, transformer; To solve traditional transformer, reactor because of coiling on iron core; Coil exposes outside magnet, can't ensure the technical problem that Electro Magnetic Compatibility and leakage field are bigger.
In order to reach the foregoing invention purpose, the technical scheme of the utility model is following: adopt the soft magnetic powder metallurgical parts to be combined into totally-enclosed pot type magnetic loop skeleton, this totally-enclosed pot type magnetic loop skeleton comprises the tank body and the three-phase stem stem of two butt joints; The tank body internal fixation of two butt joints has the three-phase stem stem, and this three-phase stem stem and said tank body constitute totally-enclosed pot type magnetic loop; The peripheral space of stem stem in totally-enclosed tank body for the coil windings place; This tank body is provided with the three-phase wire inlet-outlet.
Said three-phase stem stem has through hole vertically, and the through hole place of the corresponding three-phase stem stem of tank body also has through hole, pass said through hole through bolt after, the tank body and the three-phase stem stem of two butt joints is fixed together.
The gap in the said tank body and the line outlet place of tank body all are filled with filler.
The utlity model 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; 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 production of reactor and transformer production enterprise; Simultaneously, also have characteristics such as volume is little, loss is little, noise is little, use appropriate Magnaglo and suitable technology, the anti-high frequency performance of product can be up to 100kHz.

Embodiment
The utility model is by soft magnetic material; Adopt the integral type method of squeeze forming to process half pot type part of three stem stems of soft magnetism center band; On the stem stem, form the product that a closure is used to assemble three-phase transformer in during use half jar of two soft magnetism being placed winding coil jar lock joint.The shell of this tank body be the guard shield of this product also be the magnetic circuit part, form an enclosed magnetic loop with inner leg.This tank body is except that the line outlet of an end side surface, and integral body is the tank body of a sealing, thereby has reduced the possibility of leakage field to greatest extent.
Concrete structure adopts the soft magnetic powder metallurgical parts to be combined into totally-enclosed pot type magnetic loop skeleton referring to Fig. 1,2, and this totally-enclosed pot type magnetic loop skeleton comprises the tank body 3,4 and the three-phase stem stem 5 of two butt joints; Tank body 3,4 internal fixation of two butt joints have three-phase stem stem 5, constitute totally-enclosed pot type magnetic loop referring to Fig. 3,4 these three-phase stem stems 5 with said tank body 3,4; Stem stem 5 peripheries in totally-enclosed tank body 3,4 are the space at coil windings 7 places; This tank body is provided with three-phase wire inlet-outlet 1, is provided with turnover line terminals 6 in the three-phase wire inlet-outlet 1.
Said three-phase stem stem 5 has through hole vertically, and the through hole place of the corresponding three-phase stem stem of tank body also has through hole, pass said through hole through bolt 2 after, the tank body 3,4 and the three-phase stem stem 5 of two butt joints is fixed together.The gap in the said tank body 3,4 and line outlet 1 place of tank body all are filled with filler.
Iron-holder through increasing material and silicon content and glue content change the tank body magnetic permeability, also can be through adjusting ferromagnetic material powder grain shape the adjustment of characteristic of different, binding material reaching this purpose, thereby be implemented in the product of assembling out different technologies magnetic permeability performance under the condition that does not change overall dimension.
The tank body of the utility model adopts the assembly unit of no gap and adopts epoxide-resin glue to annotate technique for fixing, and adhesion strength is big, intensity is high, the high temperature resistant thermal endurance class that reaches 220 ℃, is applicable to the manufacturing of H level reactor product.
The product that the method that the utility model adopts the soft magnetic powder metallurgical parts to be combined into totally-enclosed pot type magnetic loop skeleton is produced; Be mainly used in electric equipment products such as making the three-phase radio-frequency rector, it mainly should be in the manufacturing field of the powerful three-phase reactor of all kinds of high, medium and low frequencies.
