Влияние отклонения напряжения питающей сети на работу асинхроного электропривода в горнорудных предприятиях

Abstract

The article is devoted to solving problems in power mining enterprises, optimum reliability in circuits providing power consumers the required quality of the supply voltage in all modes of operation of old and new mining and transport equipment and, in addition, the power supply system must be cost effective. The reliability level of power supply is implemented, including, at the expense of maintaining the power quality of the supply network. It is necessary to pay attention to the work of the most common types of electric motors in terms of the specific iron ore plant to reflect the changes in the values of the power quality. In this case the mass is asynchronous motors. In this paper, the influence of voltage fluctuations on the operation of the actuator in the range from – 10% to + 10% of the characteristic of the induction motor.
