Abstract

Изобретение относится к электротехнике и предназначено для контроля состояния конденсаторов связи на энергообъектах, может быть использовано для определения начала процесса разрушения конденсатора связи и своевременной его замены. Техническим результатом заявляемого изобретения является создание устройства, обеспечивающего постоянный контроль состояния конденсаторов связи на энергообъекте с целью определения начала процесса их разрушения и формирование соответствующего сигнала о начале и развитии этого процесса в режиме текущего времени. Для достижения указанного технического результата предлагается датчик контроля конденсатора связи, включающий входной и выходной разъемы, трансформатор, первичная обмотка которого посредством вводного разъема включается в разрыв между нижней обкладкой конденсатора связи и фильтром присоединения, диодный мост, к которому подключены выводы вторичной обмотки трансформатора, первый резистор и два конденсатора, соединенные параллельно и подключенные к выводам диодного моста, второй и третий резисторы, формирующие выходной ток, один из которых является подстроечным резистором, вторые выводы которых подключены к контактам выходного разъёма.The invention relates to electrical engineering and is intended to monitor the condition of communication capacitors at power facilities, can be used to determine the beginning of the process of destruction of the communication capacitor and its timely replacement. The technical result of the claimed invention is the creation of a device that provides constant monitoring of the state of the coupling capacitors at the power plant in order to determine the beginning of the process of their destruction and the formation of the corresponding signal about the beginning and development of this process in the current time mode. To achieve the technical result, a coupling capacitor monitoring sensor is proposed that includes input and output connectors, a transformer, the primary winding of which, through the input connector, is connected to the gap between the lower coupling capacitor plate and the connection filter, a diode bridge to which the transformer secondary windings are connected, the first resistor and two capacitors connected in parallel and connected to the terminals of the diode bridge, the second and third resistors forming the output current, one of which is a tuning resistor, the second conclusions of which are connected to the contacts of the output connector.
