本考案は、外部接続用導体など、充電部の周囲を殆ど絶
縁物で覆うことによって、小動物の侵入によって引き起
こされる短絡事故や開閉器運転上の諸問題を回避し得る
ようにした配電盤内収容の真空開閉器に関するものであ
る。[Detailed description of the invention] This invention can avoid short-circuit accidents and various problems in switch operation caused by small animal intrusion by covering most of the live parts, such as external connection conductors, with insulating material.

故を引き起こすといった欠点がある。In conventional vacuum switches, the external connection conductor is not covered with any insulating material, so small animals such as snakes, lizards, and rats may come into contact with the external connection conductor or enter the vacuum switch. It is easy to invade, which causes some trouble in the operation of the vacuum switch, and in the worst case, it can cause a short circuit accident.
また、真空開閉器が配電盤内に収容される場合、少なく
とも断路部あるいは主回路プラグなどの充電部が外部に
露出されるところから、それら露出充電部が塵埃によっ
て汚染され、これがために接触不良を引き起こし易いと

It has the disadvantage of being easy to cause.
第１図ａ、ｌ）はその従来の真空開閉器の半縦断正面と
一部縦断右側面とを示したものである。Figures 1a and 1) show a semi-vertical front view and a partially longitudinal right side view of the conventional vacuum switch.

四角筒状部分１ｂ、断面Ｕ字状部分１Ｃよりなり、これ
らの部分は一体的に形成される。As shown in the figure, only the poles of one phase bone are shown, but according to this, the insulating frame 1 consists of a cylindrical section 1a, a square cylindrical section 1b, and a U-shaped section 1C, and these sections are integrally formed.
このうち断面円筒状部分１ａには真空バルブ１５が収容
されるようになっており、その収容はボルト１１によっ
て絶縁フレーム１に取付された取付板１２を介して行な
われる。A vacuum valve 15 is housed in the cylindrical section 1a, and the vacuum valve 15 is housed through a mounting plate 12 attached to the insulating frame 1 with bolts 11.

電極は接触したり、開離Ｖることになり、真空開閉器と
しての用を果たすようになるわけである。As is well known, a pair of electrodes (not shown) which can be freely moved into and out of the vacuum valve 15 are housed inside the vacuum valve 15, and each jewel is connected to a fixed electrode rod 13 and a movable electrode rod 17, respectively. 17 through an insulated rod for 20 minutes and is driven downward by an operating device (not shown), the pair of electrodes will come into contact or be separated, thus functioning as a vacuum switch. This is how it happens.
ところで真空開閉器として実際に用を果たすたｂには固
定電極棒１３、可動電極棒１７それぞれによ外部接続用
の導体が接続される必要がある。By the way, conductors for external connection must be connected to b, which actually serves as a vacuum switch, through the fixed electrode rod 13 and the movable electrode rod 17, respectively.
