成果简介	NOVELTY - Device comprises a control unit, the first input of which is the power input, the second input is the operation blocking input, the third input is the control input, a time-current converter, a threshold value setting device, comparator, the output of which is connected to the second input of the control unit. Device additionally includes an ambient temperature meter and an adder. First input of the adder is connected to the first output of the time-current converter, the second input is connected to the output of the ambient temperature meter, and the output is connected to the first input of the comparator. Second input of the comparator is connected to the output of the threshold value setting device. Time-current converter comprises a heating element, the first output of which is the first input of the time-current converter, connected to the output of the control unit, and the second output is the second output of the time-current converter made with possibility of connection to the motor. Time-current converter also has a meter for measuring the temperature difference between the heating element and the environment, the output of which is the first output of the time-current converter. USE - Electrical engineering. ADVANTAGE - Providing the possibility of safe re-supply of supply voltage to the motor after operation of protection against overheating through any time interval with maximum use of overload capabilities in wide range of ambient temperature. 1 cl, 1 dwg
