Description of the invention (17) The wire room is adjacent to the bus bar provided on the electric trace eight power distributor; the distributor contains the power supply to and accommodates the extension from the control unit: 'System Adjacent to the power distributor, the top and bottom of the electric panel ... Also, the wiring of the equipment and equipment of the Ministry of Health is extended in the distribution room, and the power distributor is installed in the machine. —, And-the service unit of the unit will fly from the control unit to the side. There is a ventilation space inside the room. The hot air from the control unit, Yao Wu-Sister Mountain, is collected from the control unit through the power knife, Is, and discharged to: it is discharged to the outside. Therefore, a high-density control unit can be used, and at the same time, the cooling performance of the control unit can be improved. In addition, the control units stored in the unit are arranged in a checkerboard pattern. Therefore, the two can be installed in a small space and high density of most control units, at the same time, can be easy to carry out wiring, maintenance or management. Furthermore, the intake port and the exhaust port provided in the power distributor are formed in a slit shape. Therefore, there is no need to reduce the strength of the power distributor housing, and the hot air can be efficiently discharged. The intake and exhaust ports provided in the power distributor are formed as openings dedicated to exhaust. Therefore, the arc gas generated by the control unit accident can be released through this path, and the secondary accident of the bus short circuit caused by the arc gas and the like being sprayed toward the bus can be prevented, so that the expansion of the accident can be prevented. [Possibility of industrial use] The control center of the present invention includes: a unit room, which is slightly box-shaped, has an opening in the front and houses a plurality of control units; a power distributor is provided on the back of the unit room, To distribute power to multiple controllers

'Group; between the control center, there is a multi-NC distribution of the air chamber at the source. This busbar can be combined with the upper and lower power distribution of the exhaust chamber to draw in from the internal control device and exhaust system. Exhaust chamber. Therefore, the bus direction is used; while the machine's suction port system ventilates the empty room, and the rooms are closed at the same time, no room is needed. Comes from the outside. It can improve the control and set the power supply as an exhaust. This can achieve a small distributor. There is a control unit that discharges the exhaust from the distributor. Therefore, it can control the type of the unit to supply power to the air chamber. The hot air high-density cooling distributor with the control of the exhaust port is specially located on the side of the air-conditioning unit, and it is electrically connected to the busbar space, and the exhaust room is controlled by the control. The unit extends to the wiring room for wiring of external equipment. Therefore, there is no need to provide a special space for the exhaust chamber, and the busbar chamber can be used together, so that miniaturization can be achieved. The engine room is plurally arranged in the vertical direction, so the engine room is provided with a plurality of columns in the vertical direction, and the above-mentioned control unit is configured as a checkerboard grid in a plurality of columns as a whole. Therefore, it can be used to control most farms in a small space and high density, and at the same time, it can be easily wired, repaired or managed. The exhaust port provided in the power distributor also serves as a discharge opening for discharging electrical isolation generated in the power distributor. Therefore, it is possible to release the arc generating gas generated by the control unit accident from this path ', so that no two accidents of the bus short circuit caused by the arc gas or the like being sprayed toward the bus can occur, so the expansion of the accident can be prevented. .
