Устройство предназначено для защиты асинхронных электродвигателей, работающих с тиристорными преобразователями, и направлено на решение задач повышения надежности и расширения возможностей устройства. Это достигается тем, что аналоговый сигнал первичных датчиков тока преобразуется в импульсный, в результате чего повышается надежность устройства в целом и становится возможным применение данного устройства в тиристорных регуляторах напряжения.The device is designed to protect asynchronous electric motors working with thyristor converters, and is aimed at solving problems of increasing the reliability and expanding the capabilities of the device. This is achieved in that the analog signal of the primary current sensors is converted into a pulse, resulting in increased reliability of the device as a whole and it becomes possible to use this device in thyristor voltage regulators.
