Abstract

PURPOSE: To prevent the reset of an operation circuit due to instantaneous service interruption, by mounting a holding means for continuously operating an electromagnetic contactor for operation as a countermeasure to the instantaneous service interruption.
CONSTITUTION: A holding means, sulch as, a condenser, etc. for successively operating an electromagnetic contactor for operation is installed as a countermeasure to instantaneous service interruption. A direct current relay X' is used for a starting system by Y-Δ change-over, which employs a timer TLR, as an auxiliary relay, and a smoothing condenser C and a diode D, etc. for converting alternating currents and direct currents are connected to the relay X'. When there happen instantaneous service interruption, the contacts X1', X2' of the direct current relay X' continuously operate because the relay X' operates in succession within a fixed time by the discharge currents of the smoothing condenser C, the electromagnetic contactor MCΔ for operation immediately starts its making operation by the closing of a generator power source even if it previously returns, and an induction motor continues Δ operation.
