【考案の詳細な説明】
この考案は配線用しや断器(以下MCBという)
を収納した閉鎖配電盤に関する。[Detailed explanation of the invention] This invention is called a wiring circuit breaker (hereinafter referred to as MCB).
Concerning a closed switchboard containing a.
MCBは低圧回路に使用されるので絶縁距離を
さほど考慮する必要がなく従つてこれを閉鎖配電
盤に多数収納することができる。この場合取付板
上に多段に且つ複数列配列すると取付板の裏面に
おいて電源側母線と負荷側ケーブルが交叉するこ
とになるので接続作業、保守点検等がやつ介にな
る。このためMCBを盤中央部に横向きにして縦
1列に配列し、MCBの左右を電源側母線室、負
荷側ケーブル室とすれば母線、ケーブルが交叉し
ないので前記の欠点を解消できる。しかしこの場
合でも最近のように配電盤の設置面積を縮小する
ためその奥行寸法を短縮したうす形配電盤にあつ
ては裏面側を建屋の壁に接して据付けられるの
で、保守点検は前面の制御配線室から行うことに
なる。その際左右の電源側母線、負荷側ケーブ
ル、MCB本体の各充電部が露出しているので感
電の危険性があつた。 Since MCBs are used in low-voltage circuits, insulation distances do not have to be considered so much and therefore a large number of MCBs can be housed in a closed switchboard. In this case, if they are arranged in multiple stages and in multiple rows on the mounting plate, the power supply side busbar and the load side cable will intersect on the back side of the mounting plate, making connection work, maintenance inspection, etc. difficult. For this reason, if the MCBs are arranged horizontally in the center of the board in a single vertical row, and the left and right sides of the MCB are used as a power supply side busbar room and a load side cable room, the busbars and cables will not intersect, and the above-mentioned drawback can be solved. However, even in this case, in the case of thin type switchboards, which have been recently reduced in depth to reduce the installation area of the switchboard, they can be installed with the back side touching the wall of the building, so maintenance and inspection can be carried out in the control wiring room in the front. This will be done from. At that time, there was a risk of electric shock because the left and right power supply side busbars, load side cables, and live parts of the MCB body were exposed.
この考案は以上の点に留意して提案されたもの
でMCB本体の充電部を含み電源側母線室及び負
荷側ケーブル室を制御配線室としやへいする開閉
自在且つ着脱自在の防護板を設けたことを特徴と
する。 This idea was proposed with the above points in mind, and includes a protective plate that can be opened, closed, and detached to protect the power supply side busbar room and load side cable room as a control wiring room, including the live parts of the MCB main body. It is characterized by
以下この考案の一実施例を図について説明す

扉である。 1 is the closed switchboard body, and 2 are each arranged horizontally in a single vertical row approximately in the center of the panel body.
In the case of the MCB shown in the figure, five are mounted. 3 is
This is a mounting bracket for fixing the MCB 2 to the board body 1. Reference numeral 4 designates a busbar room that accommodates the power supply side busbar 5 and branch busbar 6, and 7 a cable room that accommodates the load side cable 8. A branch busbar 6 and a cable 8 are connected to the left and right terminals of each MCB 2, respectively. Reference numerals 9 denote protective plates made of metal that protect the live parts of each MCB 2, the busbar chamber 4, and the cable chamber 7, respectively.
Each of the protective plates 9 is detachably attached to a fixing plate 11 via a sliding hinge 10 and can be opened and closed, and can be fixed to the mounting bracket 3 with screws 12. In addition, 13 is MCB2 ON,
OFF operation knob, 14 is a control wiring room, and 15 is a front door.

なる効果を奏する。 In this way, according to this proposal, the live parts, busbar room, and cable room of the MCB are protected by a protective plate made of metal, and this protective plate is made detachable from the fixing plate and can be opened and closed, thereby preventing accidental damage to the busbar. Since you cannot get close to the live parts of the room, cable room, and MCB, there is no risk of electric shock, and the protective plate is removable and can be opened and closed, making maintenance and inspection easier.
