本発明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 comprising 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.
面して、そのグリッドへのアークの移行を容易するよう
可動、一定接接点から同電位的にアーク走行板をグリッ
ド家で引會出している。Facing the grid, an arc running plate is drawn at the same potential from a movable, fixed contact to facilitate the transfer of the arc to 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

の磁性体に起磁束を発生させ、磁気駆動力としてアーク
を更に趨く移行さ曽ることか開発された。Furthermore, in order to make the transition of the arc even stronger, a magnetic material is placed near the fixed contact plate, and a large current at the time of interruption generates magnetic flux in the magnetic material, which acts as a magnetic driving force to further propel the arc. It has been developed for some time now.
ところが、この磁性体は主に鉄板のため、接点１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
せる必要がある。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、スペース的に無駄か生じて磁気抵抗が増大した
。Therefore, space was wasted and magnetic resistance increased.
（目 的）

とを目的としたものである。(Purpose) The present invention has been made in consideration of the above points, namely, the magnetic material for magnetic drive is compared to iron, and the space between the contact plate and the contact plate is reduced by using soft ferrite with excellent insulation properties. The purpose is to make it as small as possible, use iron with high magnetic flux density on the side of the device to increase magnetic efficiency, and concentrate the magnetic flux in one place to further increase efficiency.

小さくなって磁気動電が向上する。(Effects) As described above, the present invention has the constant contact plate 7 and the rising side I of the device l.
The vertical piece 14 interposed between the I3 and the side pieces 15 located on both sides of the fixed contact plate 7 are made of a U-shaped frame 13 made of ferrite rice.
Since this U-shaped frame 13 is placed near the contact plate 7 with a space, the space is narrowed because the magnetic material for magnetic drive of the arc is soft ferrite, which has superior insulation properties compared to iron. Therefore, not only the space but also the magnetic resistance is reduced and the magnetoelectrodynamics is improved.

It will be further strengthened.
