Description
II
Изобретение относитс к устройствам защиты индуктивных нагрузок, питающихс отодного источника питани , и может быть использованов системе управлени прокатным станом.The invention relates to inductive load protection devices fed from one power source, and can be used in a rolling mill control system.
Известно устройство защиты от перенапр жений индуктивных нагрузок, содержащее пороговый элемент, диоды и резис;тор 1. Однако это устройство имеет больщое врем срабатывани .A protective device for overvoltage inductive loads is known, which contains a threshold element, diodes and resistor; Torus 1. However, this device has a longer response time.
Наиболее близким к изобретению вл етс устройство дл защиты от перенапр жений , содержащее два динистора, катоды которых соединены с зажимами источника питани , резистор и диоды 2.Closest to the invention is an overvoltage protection device comprising two dynistors, the cathodes of which are connected to the power supply terminals, a resistor and diodes 2.
Недостатком известного устройства вл етс его сложность.A disadvantage of the known device is its complexity.
Цель изобретени - упрощение устройства .The purpose of the invention is to simplify the device.
Дл этого в известном устройстве аноды динисторов соединены и через резистор и разв зывающие диоды подключены к зажимам защищаемых элементов.For this, in the known device, the anodes of the dynistor are connected and through a resistor and the isolating diodes are connected to the terminals of the protected elements.
На чертеже дана структурна схема устройства защиты.The drawing is a block diagram of the protection device.
Устройство работает следующим образом. Импульсы переходного перенапр жени с индуктивных элементов 1, 2, 3 и 4 через соответствующие диоды 5, 6, 7, 8 и 9 и резистор 10 открывают динистор 11 или 12, 5 через которые импульсы перенапр жени замыкаютс на источник питани .The device works as follows. Transient overvoltage pulses from inductive elements 1, 2, 3 and 4 through the corresponding diodes 5, 6, 7, 8 and 9 and resistor 10 open distor 11 or 12, 5 through which the overvoltage pulses close to the power supply.
