Abstract

The invention relates to electrical engineering. The device has current transformers, secondary windings are connected to respective three-phase bridge-circuit rectifier input, a function generator consisting of two parallel resonance circuits for double electric motor power frequency, and a polar condenser. The average points of parallel circuits are connected via diode and resistor with conductivity direction from a resonance circuit to the voltage distributor. The thermal contact of analog electric motor – polar condenser is a voltage distributor element. The threshold element is connected to a positive polar condenser input and outputs are connected to one actuating element terminal, a direct current electromagnetic relay coil, the second actuating element terminal is connected to a negative polar condenser output. The electromagnetic relay contact is used in the electric motor control circuit.
