Description

この発明は、コントロールセンタの回路構成単位であるコントロールセンタの機能ユニット及びその製造方法に関するものである。  The present invention relates to a functional unit of a control center, which is a circuit configuration unit of the control center, and a manufacturing method thereof.

ＪＥＭ−１１９５には、コントロールセンタの機能ユニットは、ある機能を満たすのに必要な主回路及び補助回路の機器を備えたモータコントロールセンタの一回路構成単位と規定されている。
機能ユニットには、コントロールセンタの外箱の構成部分に固定して装着され、主回路が停電状態でのみ、コントロールセンタから完全に切り離されたり、機器の交換が可能となる固定形機能ユニットと、主回路が充電状態であってもコントロールセンタから安全に切り離されたり、機器の交換が可能な引出・保持機構を備えた引出機能ユニット（特許文献１参照）とがある。 In JEM-1195, a functional unit of a control center is defined as a circuit configuration unit of a motor control center including main circuit and auxiliary circuit devices necessary to satisfy a certain function.
A fixed functional unit that is fixedly attached to the component of the outer box of the control center and can be completely disconnected from the control center or replaced with equipment only when the main circuit is in a power failure state. There is a drawer function unit (see Patent Document 1) provided with a drawer / holding mechanism that can be safely disconnected from the control center even when the main circuit is in a charged state, or can be replaced.

機能ユニットには、主回路より電力を受ける部分、負荷に電力を送る部分、ある機能を満たすための制御機器部があり、これらは機能ユニット筐体に配置・配線されている。引出形機能ユニットは、主回路が充電状態であっても、コントロールセンタから機能ユニットの主回路を安全に切離し、機器の交換が可能な引出・保持機構を備えている。機能ユニットに収納される収納機器は、顧客の仕様に応じて変わることが多い。このため、収納機器が変わる度に、機能ユニットの上記の電力を受ける部分、負荷に電力を送る部分、制御機器部、引出・保持機構の４つの構成部材の位置を考慮して、設計する必要があった。   The functional unit has a part that receives power from the main circuit, a part that sends power to the load, and a control device part that satisfies a certain function. These are arranged and wired in the functional unit housing. The drawer type functional unit includes a drawer / holding mechanism that can safely disconnect the main circuit of the functional unit from the control center and replace the device even when the main circuit is in a charged state. The storage equipment stored in the functional unit often changes according to customer specifications. For this reason, each time the storage device changes, it is necessary to design in consideration of the position of the four components of the functional unit that receives the power, the portion that sends power to the load, the control device, and the drawer / holding mechanism. was there.

特許文献２は、コントロールセンタの単位装置のフレームを上下方向に分割し、この分割した上下のフレームを、上下方向に寸法調整可能な調整手段により連結し、収納する回路用品の大きさが変わった時に調整できるようにしたものが、示されている。
しかし、この特許文献２は、収納する回路用品の変更により、高さ方向にしかフレームを調整できないという問題があった。 In Patent Document 2, the frame of the unit device of the control center is divided in the vertical direction, and the divided upper and lower frames are connected by adjusting means capable of adjusting the size in the vertical direction, and the size of the circuit article to be stored is changed Something that can be adjusted from time to time is shown.
