<P>PROBLEM TO BE SOLVED: To provide a wiring structure for coupling main circuits of respective function units to a power supply side and a load side automatically, in a control center in which a plurality of drawing-type function units are aligned laterally on upper and lower stages in a board. <P>SOLUTION: A plurality of drawing-type function units 2, each consisting of an assembly of a circuit breaker 22 and a monitoring control equipment, are aligned laterally in a unit housing frame 5 and mounted on a control center. In the control center, an automatically-coupling type power supply side contact 28 and an automatically-coupling type load side contact 29 are provided on a back face of each function unit 2. A relay contact unit 7 consisting of a contact plug 7a and a horizontal bus 7b, and a contact socket 29b are arranged on a back face of the unit housing frame 5 so as to be opposed to the contacts. With this structure, the main circuit of each of the function units 2 is connected with a power supply side vertical bus 6 installed in the board, and with a load connection terminal base 8 arranged on a lateral part of the frame. <P>COPYRIGHT: (C)2012,JPO&INPIT |
