Изобретение относитс  к электротехнике , в Частности к магнитопроводам индукционных устройств малой мощности, например дроссел м.The invention relates to electrical engineering, in particular, to magnetic circuits of low-power induction devices, for example, Drossel m.

Известен магнитопровод индукционного устройства из ферромагнитных пластин, набранных в V образный и Т-образный пакеты, последний из которых состоит, из Т-образных пластин 1 .Known magnetic induction device of ferromagnetic plates, assembled in a V-shaped and T-shaped packages, the last of which consists of T-shaped plates 1.

Данное устройство наиболее близкое к изобретению по технической сущности и достигаемому результату.This device is closest to the invention according to the technical essence and the achieved result.

Недостатком такого магнитопровода  вл ютс  большие потери материала при изготовлении его, так как пластины V o6pa3Horo пакета магнитопровода выполн ютс  цельными и при вырубке их из соответствующих пластин-заготовок возникают повышенные потери материала.The disadvantage of such a magnetic circuit is the large losses of material during its manufacture, since the V o6pa3Horo plates of the magnetic circuit packet are made in one piece and when they are cut from the respective blank plates, there is an increased loss of material.

Цель изобретени  - повышение экономичности изготовлени  магнитопровода .The purpose of the invention is to increase the cost-effectiveness of manufacturing the magnetic circuit.

Указанна  цель достигаетс  тем, что в магнитопроводе индукционного устройства из ферромагнитных пластин , набранных в V-образный пакет и Т-образный пакет, состо щий из Т-образных пластин, V oбpaзный пакет набран из Г-образных пластин, торцы которых выполнены с фасками, найравлени среза которых совпадает с направлением линии, проведенной от внутреннего к внешнему углу Г-образной пластины. При этом с целью расйшрени  функциональных возможностей магнитопровода он снабжен бруске, Т-образные пластины выпол10 нены с пазами на нижних торцах вертикальных ножек, в которых установлен брусок 1с образованием воздушного зазора между нижними торцами вертикальных ножек Т-образных пластин и This goal is achieved by the fact that in the magnetic core of an induction device of ferromagnetic plates assembled in a V-shaped package and a T-shaped package consisting of T-shaped plates, the V shaped package is assembled of L-shaped plates, the ends of which are chamfered, The cut of the slice coincides with the direction of the line drawn from the inner to the outer corner of the l-shaped plate. For the purpose of enhancing the functionality of the magnetic core, it is provided with a bar, T-shaped plates are made with grooves on the lower ends of the vertical legs, in which the bar 1c is installed forming an air gap between the lower ends of the vertical legs of the T-shaped plates and
