Abstract

PURPOSE: To enable a bypass motor power supply to be easily selected at the time of checking a normal motor power supply only through the selective operation of a single power switch by providing the single power switch with contacts respectively connected to a control power supply, the normal motor power supply and the bypass motor power supply.
CONSTITUTION: In a normal disconnector on/off operation, the switch 4a of a normal motor power supply 4 is turned on, and a motor 25 becomes ready to operate. In this state, a power switch 8 is turned on. Then, the control power supply contacts 9 and 10 of the power switch 8, and normal motor power supply contacts 11 and 12 are turned on, thereby enabling power to be supplied from a control power supply 3 to electromagnetic contactors 18 and 19, as well as from the normal motor power supply 4 to the motor 25. In this state, when the on/off switches 2a and 2b of an operation panel 2 are turned on, the on/off electromagnetic contactors 18 and 19 connected thereto operate, and the contact 23 or 24 thereof is turned on. Consequently, the motor 25 is driven to the 'on' or 'off' side of the disconnector thereby, closing or opening the disconnector.
