Description

Изобретение относитс  к устройствам дл  релейной защиты сетей высокого напр жени , отключающим участок сети с поврежденной секцией при помощи головного выключател  и осуществл ющим последовательные автоматические повторные включени  (АПВ) последнего дл  отключени  поврежденной секции и восстановлени  питани  всех секций участка, расположенных до поврежденной секции.The invention relates to devices for relay protection of high voltage networks, disconnecting a section of a network with a damaged section using a head switch and performing sequential automatic reclosing of the latter to disconnect the damaged section and restore power to all sections of the section located before the damaged section.

Согласно изобретению, с целью сокращени  циклов АПВ до двух, предлагаетс  выполн ть схему так, чтобы при первом отключении головного выключател  все выключатели отдельных секций участка автоматически отключались и после первого АПВ включались последовательно вновь, начина  с головной секции.According to the invention, in order to reduce the AR cycles to two, it is proposed to carry out the scheme so that when the head switch is first disconnected, all the switches of the individual sections of the section are automatically turned off and after the first AR automatically turned on again, starting from the head section.

При наличии повреждени  происходит второе отключение головного выключател  и второе АПВ с последовательным включением всех секций , которые снабжаютс  деблокировкой от второго включени , срабатывающей после вторичного восстановлени  цитани  с выдержкой времени , выбранной так, чтобы на поврежденной секции деблокировка не Срабатывала. . - На чертеже приведена электрическа  схема предлагаемого устройства .In the presence of damage, a second switch-off of the main switch and a second automatic reclosing occur with sequential switching-on of all sections, which are supplied with the release from the second switch-on, which is triggered after the secondary restoration of the citation with a time delay selected so that the enabled section does not activate. . - The drawing shows the electrical circuit of the proposed device.

На фидерах питательных пунктов высоковольтной сети устанавливаетс  мгновеннодействующа  защита от повреждений, дополненна  схемой автоматического повторного включени . Защиты согласно приведенной схеме устанавливаютс  в различных точках сети. При повреждении в сети срабатывает защита на питательHiOM пункте и отключает поврокдейный фидер.Instantaneous protection against damage is added to the feeders of the feeding points of the high-voltage network, supplemented by an automatic reclosing circuit. The protections according to the above scheme are installed at various points in the network. If the network is damaged, protection at the feed point of the HiOM item is triggered and disables the rotary feeder.

Вследствие исчезновени  напр жени  реле напр жени  / замыкают с некоторой заранее отрегулированной выдержкой времени свои нормально замкнутые контакты и отключают расположенные за ними участки сети . Спуст  установленное врем , фидер автоматически повторно включаетс  на питательном пункте. После восстановлени  напр жени  происходит последовательное включение участков сети под воздействием реле напр жени  1, мгновенно замыкающих свои нормально разомкнутые контакты и действующих через промежуточные реле 2. Реле 2 снабжены механической блокировкой против повторного действи  и имеют также приспособление дл  электромагнитного возврата {деблокиров283Due to the disappearance of the voltage of the voltage relay / with its pre-adjusted time delay, they close their normally closed contacts and disconnect the network sections behind them. After a set time, the feeder is automatically re-enabled at the feed point. After the restoration of the voltage, the network sections are successively connected under the influence of voltage relays 1, which instantly close their normally open contacts and act through intermediate relays 2. Relays 2 are equipped with a mechanical interlock against repeated action and also have a device for electromagnetic return {deactivated 283
