Analysis of hardware protection of squirrel-cage induction motors with voltage up to 0.66 kV against overloads and overheating

An analysis of the hardware protection of asynchronous motors with a short-circuited rotor with a voltage of up to 0,66 kV against overloads and overheating, implemented in accordance with modern standards, was carried out. The causes and factors of engine overheating and the functional features of the specified protection devices are considered. Conclusions were made regarding the effectiveness of certain types of protection against overloads and overheating of engines and their combination in order to increase the reliability of protection. The most promising directions for improvement of hardware protection against overload and overheating of asynchronous motors have been established
