Document Type and Number:
Japanese Patent JPS5849095
Kind Code:
A
Abstract:
PURPOSE:To simplify the power source supply facility without loss of monitoring and protecting functions by individually monitoring each motor group with a motor monitor and sub-breaker provided at each sub-power distribution panel. CONSTITUTION:A power source is supplied ordinarily in a route of a power source 11, a main power distribution panel 12 and sub power distribution panels 17l-17n, and motor groups 22l-22n. When a motor such as M1 in 22l malfunctions, a motor monitor 181 of the sub panel 171 provided corresponding to the motor group and hence 22l, to which the motor is belonging, is operated, thereby operating a responsive device 23l. Accordingly, the occurrence of a malfunction in either motor of the motor group 22l is notified by the indication of a lamp of the panel 17l. When the malfunction is excessive, the subbreaker 19l is tripped, thereby interrupting the power source supply to the motor group 22l.
