本発明は配電盤に関し、特に、移動形機器（または引出形機器）を配電盤内で移動させることにより、電源側断路部と負荷側断路部との間が開閉される構造に適用して好適なものである。   The present invention relates to a switchboard, and in particular, is suitable for application to a structure in which a movable device (or a drawer-type device) is moved in the switchboard to open and close between a power supply side disconnection portion and a load side disconnection portion. It is.

高圧受配電設備などに使用される配電盤では、遮断機などの開閉器が搭載された移動形機器を単位ユニットとして上下方向に１段または多段積みにして配電盤に収納する方法がある（特許文献１）。このような配電盤では、運転位置と断路位置との間で移動形機器を配電盤の奥行き方向に移動させることにより、電源側断路部および負荷側断路部と移動形機器の間が開閉される。そして、移動形機器が運転位置と断路位置との間を移動できるようにするため、正面扉と移動形機器の間にスペースが形成されるように配電盤の寸法が設定される。そして、移動形機器の引出または挿入操作を行う場合、正面扉を開放した状態で移動形機器を移動させ、移動形機器の引出または挿入操作が完了すると、正面扉を閉じるのが一般的である。   In a distribution board used for a high-voltage power distribution facility, there is a method in which a mobile device equipped with a switch such as a circuit breaker is stored as a unit unit in one or more layers in the vertical direction and stored in the distribution board (Patent Document 1). ). In such a switchboard, the movable device is moved in the depth direction of the switchboard between the operating position and the disconnect position, thereby opening and closing the power-side disconnect portion and the load-side disconnect portion and the mobile device. Then, in order to allow the mobile device to move between the operation position and the disconnection position, the dimensions of the switchboard are set so that a space is formed between the front door and the mobile device. Then, when performing a pull-out or insertion operation of the mobile device, it is common to move the mobile device with the front door open and close the front door when the pull-out or insertion operation of the mobile device is completed. .

一方、配電盤の操作時の安全性を向上させるため、正面扉を閉じた状態で運転位置と断路位置との間で移動形機器を移動させたり操作したりすることができる外部操作機構を設ける方法もある。

しかしながら、従来の配電盤において内部操作方式を採用した場合、移動形機器の引出または挿入操作を行うために正面扉を開放する必要があり、断路位置２ｃと運転位置２ｄとの間で移動形機器１を移動させるためのスペースをユニット室２に確保する必要があることから、配電盤の奥行きが大きくなるという問題があった。
一方、従来の配電盤において外部操作方式を採用した場合、移動形機器１を外部から移動させたり操作したりする外部操作機構が必要となることから、配電盤のコストアップを招くとともに、外部操作機構を収納するためのスペースが余分に必要になるという問題があった。
そこで、本発明の目的は、外部操作機構を別途設けることなく、正面扉を閉じたままで移動形機器を外部から移動させたり操作したりすることが可能な配電盤を提供することである。 However, when the internal operation method is adopted in the conventional switchboard, it is necessary to open the front door in order to pull out or insert the mobile device, and the mobile device 1 is between the disconnection position 2c and the operation position 2d. There is a problem that the depth of the switchboard becomes large because it is necessary to secure a space for moving the unit in the unit chamber 2.
On the other hand, when the external operation method is adopted in the conventional switchboard, an external operation mechanism for moving and operating the mobile device 1 from the outside is required, which increases the cost of the switchboard and reduces the external operation mechanism. There was a problem that extra space was required for storage.

FIG. 2 is a perspective view showing a method for attaching a protective cover to the front door of the switchboard in FIG. 1. FIG. 2 is a cross-sectional view showing a schematic configuration when the mobile device mounted on the switchboard in FIG. The same parts as those in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

図１において、配電盤には、移動形機器１を収納するユニット室２が設けられ、ユニット室２の前面には、開閉可能な正面扉１５が設けられている。なお、正面扉１５の開閉方式は、回転式であってもよいし、前後に移動可能な引き出し式であってもよいし、上下に移動可能なシャッタ式であってもよい。
そして、正面扉１５には、移動形機器１に設けられた操作部１ｂおよび取手１ｃの少なくとも一部を外部に突出させる開口部５ａが形成されている。また、正面扉１５には、移動形機器１に設けられた操作部１ｂおよび取手１ｃの少なくとも一部が突出した状態で開口部５ａを覆う防塵用の保護カバー６が脱着自在に装着されている。ここで、保護カバー６には、正面扉１５に保護カバー６を装着するための取り付け金具６ａが設けられている。 In FIG. 1, the switchboard is provided with a unit chamber 2 that houses the mobile device 1, and a front door 15 that can be opened and closed is provided in front of the unit chamber 2. The opening / closing method of the front door 15 may be a rotary type, a drawer type that can be moved back and forth, or a shutter type that can be moved up and down.
The front door 15 is formed with an opening 5a for projecting at least a part of the operation unit 1b and the handle 1c provided in the movable device 1 to the outside. The front door 15 is detachably mounted with a dust-proof protective cover 6 that covers the opening 5a in a state where at least a part of the operation unit 1b and the handle 1c provided on the mobile device 1 protrudes. . Here, the protective cover 6 is provided with a mounting bracket 6 a for attaching the protective cover 6 to the front door 15.

そして、図１（ａ）に示すように、正面扉１５を閉じた状態で保護カバー６を外し、開口部５ａを介して移動形機器１を外部から操作しながら、移動形機器１を運転位置２ｄに移動させることで、負荷側断路部１３ａと負荷側接触端子１１ａとを接触させ、負荷側断路部１３ａと負荷側接触端子１１ａとの間で電路を形成するとともに、電源側断路部１３ｂと電源側接触端子１１ｂとを接触させ、電源側断路部１３ｂと電源側接触端子１１ｂとの間で電路を形成することができる。   Then, as shown in FIG. 1A, the protective cover 6 is removed with the front door 15 closed, and the mobile device 1 is operated from the outside through the opening 5a while operating the mobile device 1 from the outside. 2d, the load-side disconnecting part 13a and the load-side contact terminal 11a are brought into contact with each other, and an electric circuit is formed between the load-side disconnecting part 13a and the load-side contact terminal 11a, and the power-side disconnecting part 13b The power supply side contact terminal 11b is brought into contact, and an electric circuit can be formed between the power supply side disconnecting portion 13b and the power supply side contact terminal 11b.

また、図１（ｂ）に示すように、正面扉１５を閉じた状態で保護カバー６を外し、開口部５ａを介して移動形機器１を外部から操作しながら、移動形機器１を断路位置２ｃに移動させることで、負荷側断路部１３ａと負荷側接触端子１１ａとを離間させ、負荷側断路部１３ａと負荷側接触端子１１ａとの間の電路を切断するとともに、電源側断路部１３ｂと電源側接触端子１１ｂとを離間させ、電源側断路部１３ｂと電源側接触端子１１ｂとの間の電路を切断することができる。   Further, as shown in FIG. 1 (b), the protective cover 6 is removed with the front door 15 closed, and the mobile device 1 is operated from the outside through the opening 5a while the mobile device 1 is disconnected. 2c, the load-side disconnecting portion 13a and the load-side contact terminal 11a are separated from each other, the electrical path between the load-side disconnecting portion 13a and the load-side contact terminal 11a is disconnected, and the power-side disconnecting portion 13b The power supply side contact terminal 11b can be separated from the power supply side disconnecting portion 13b and the power supply side contact terminal 11b.

そして、移動形機器１を断路位置２ｃに移動させると、図２に示すように、正面扉１５に保護カバー６を装着し、取り付け金具６ａにて正面扉１５に保護カバー６を固定することができる。
これにより、外部操作機構を別途設けることなく、正面扉１５を閉じたままで移動形機器１を外部から移動させたり操作したりすることが可能となり、コストアップを抑制しつつ、配電盤のコンパクト化を図ることが可能となる。 Then, when the mobile device 1 is moved to the disconnecting position 2c, as shown in FIG. 2, the protective cover 6 is attached to the front door 15, and the protective cover 6 is fixed to the front door 15 with the mounting bracket 6a. it can.
This makes it possible to move or operate the mobile device 1 from the outside with the front door 15 closed without separately providing an external operation mechanism, thereby reducing the cost of the switchboard while suppressing an increase in cost. It becomes possible to plan.

また、開口部５ａを覆う保護カバー６を正面扉１５に装着することにより、操作部１ｂと開口部５ａとの間に隙間５ｂが形成された場合においても、防塵効果を得ることが可能となるとともに、操作部１ｂの誤操作を防止することができる。
なお、操作部１ｂと開口部５ａとの間の隙間５ｂを塞ぐために、操作部１ｂと開口部５ａとの間の隙間５ｂにパッキンを設けるようにしてもよい。この場合、正面扉１５の開閉方式は、前後に移動可能な引き出し式が望ましい。 Further, by attaching the protective cover 6 covering the opening 5a to the front door 15, even when a gap 5b is formed between the operation portion 1b and the opening 5a, a dustproof effect can be obtained. At the same time, erroneous operation of the operation unit 1b can be prevented.
In order to close the gap 5b between the operation unit 1b and the opening 5a, a packing may be provided in the gap 5b between the operation unit 1b and the opening 5a. In this case, the opening / closing method of the front door 15 is preferably a pull-out type that can move back and forth.

図３において、正面扉１５の開口部５ａの周囲にはパッキン１７が設けられている。ここで、パッキン１７は、操作部１ｂが開口部５ａに挿入された時に操作部１ｂに対して摺動自在に構成されている。なお、パッキン１７は、ゴムなどの弾力性のある材料で構成することができる。そして、パッキン１７は、押さえ板１９を介してボルト１８にて正面扉１５に固定されている。
これにより、操作部１ｂと開口部５ａとの間に隙間５ｂが形成された場合においても、保護カバー６を取り付けることなく、操作部１ｂと開口部５ａとの間に隙間５ｂを塞ぐことが可能となり、防塵効果を得ることが可能となる。 FIG. 3 is a perspective view showing a configuration in which packing is attached to the front door of the switchboard of FIG.
In FIG. 3, a packing 17 is provided around the opening 5 a of the front door 15. Here, the packing 17 is configured to be slidable with respect to the operation portion 1b when the operation portion 1b is inserted into the opening 5a. The packing 17 can be made of an elastic material such as rubber. The packing 17 is fixed to the front door 15 with bolts 18 via a pressing plate 19.
Thereby, even when the gap 5b is formed between the operation portion 1b and the opening 5a, the gap 5b can be closed between the operation portion 1b and the opening 5a without attaching the protective cover 6. Thus, a dustproof effect can be obtained.
