In this work it is proved analytically that in asynchronous motors of series 4A and 5A, during operation, there is a voltage of the third harmonic with a frequency of 150 Hz as a component of the voltage U00͗ (voltage between the points “zero network – zero engine”). The nature of the origin of the voltage of the third harmonic in the working engine in a symmetrical mode in the conditions of saturation of its magnetic system has been revealed. The presence of a third harmonic in the voltage of U00͗ in asynchronous engines, the magnitude and nature of its change, gives a fundamental opportunity to use this voltage as a source of emergency signal of emergency break mode of the phase of the feeding network. |
