零発骨は例えばしゃ断器に用いられる積層グリッドより
なる消弧装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to an arc extinguishing device made of a laminated grid used, for example, in a circuit breaker.
（従来技術の問題点）
この種、消弧装置はグリッドを複数枚積層して発弧部側
からガスを吸い込んで上下グリッド間にて分割しつつ排
気部側に導會出している。(Problems with the Prior Art) This kind of arc extinguishing device stacks a plurality of grids, sucks in gas from the arc generating part side, divides it between the upper and lower grids, and guides it to the exhaust part side.
而して、そのグリッドへのアークの移行を容易にするよ
う可動、Ｉｌｌ定接接点ら同電位的にアーク走行板をグ
リッド家て引會出している。In order to facilitate the transfer of the arc to the grid, the arc running plate is drawn out from the movable constant contact at the same potential as the grid.
更によりアークの移行を強力なものとするよう固定接点
板の近傍に磁性体を位置させ、しゃ断時の大電流でその
磁性体に起磁束を発生させ、磁気駆動力としてアークを
更に速く移行させることが開発された。Furthermore, in order to make the transition of the arc even stronger, a magnetic body is placed near the fixed contact plate, and the large current at the time of interruption generates magnetic flux in the magnetic body, which acts as a magnetic driving force and causes the arc to transition even faster. That was developed.
ところが、この磁性体は主に鉄板のため、接点板との絶
縁が問題となり、空間を広めたり、又絶縁板を介在さぜ
る必要がある。However, since this magnetic material is mainly made of iron plates, insulation from the contact plate becomes a problem, and it is necessary to increase the space or interpose an insulating plate.
従って、スペース的に無駄が生じて磁気抵抗が増大し、
又別部品も必要となった。Therefore, space is wasted, magnetic resistance increases,
Additional parts were also required.
（目 的）
本発明は上記の点に鑑みてなしたものであって、即ち磁
気駆動用の磁性体を鉄に比し、絶縁性が優れたソフト７
エライトを用いて空間を極力小さくして磁気効率を高め
、且つ部品数の削減と、而もその磁束を一個所に集中さ
せ、より効率を高めることを目的としたものである。(Purpose) The present invention has been made in view of the above points, that is, the magnetic material for magnetic drive is made of soft 7 with excellent insulation properties compared to iron.
The purpose of this is to use ELITE to minimize the space and increase magnetic efficiency, reduce the number of parts, and concentrate the magnetic flux in one place to further increase efficiency.

i! ! A fixed contact plate having a fixed brass point 5 and rising along the side wall 3, the upper end 71 of which is connected to the external terminal device 8. Reference numeral 9 represents a grid block facing the arcing portion X, in which a plurality of grids 10 are stacked. 11 is a movable contact 4Il
Move the arc to the grid block 9. The movable contact side arc running plate 12 is a fixed contact arc running plate, one end 12m of which is welded to the lower end 71 of the fixed contact plate 7, and runs along the bottom wall 2. 18 is a U-shaped formwork made of soft ferrite, with fixed line dot plate 7 and eccentric I! 3, and both side pieces 15 located on both sides of this constant contact plate 7, and both side pieces Is have inward protrusions 16 facing each other.
又、このコ字型枠１３は固定接点板７と空間をおいて位

る絶縁シートも不要となる。(Effects) As described above, the present invention improves the rise and fall of the fixed contact plate 7 and the device l.
A vertical piece 14 interposed between the contact plate 13 and both side pieces 15 located on both sides of the fixed contact plate 7 constitute a U-shaped shoe frame 13 made of soft ferrite. Because it is placed near the plate 7, the magnetic material for magnetic drive of the arc is soft ferrite, which has better insulating properties than iron, which narrows the space. Efficiency is improved and an insulating sheet, which is a separate component, is not required.

力をより一層強める効果がある。Furthermore, in the present invention, since the inward protrusions 16 facing each other are provided on both sides 15 of the U-shaped split frame 13, the magnetic flux is concentrated between the inward protrusions 16, and a stronger magnetic field is formed to increase the magnetic driving force of the arc. It has the effect of further strengthening the
