(50 УСТРОЙСТВО ДЛЯ БЛОКИРОВКИ ОБХОДНЫХ РАЗЪЕДИНИТЕЛЕЙ(50 DEVICE FOR LOCKING BYPASS DISCONNECTORS
1one
Изобретение предназначено дл пользовани .в распределительных уст- ройствах высокого напр жени , в частности в схемах подстанции с обходной системой шин.The invention is intended to be used in high voltage distribution devices, in particular in substation circuits with a bypass busbar system.
Известны схемы блокировки выключател с-соответствующими ему разъединител ми , запрещающие операции включени и отключени разъединителей при включенном выключателе i присоединени , содержащие блок-замки разъединителей и блок-контакты выключател .Circuit breaker interlocking circuits with disconnectors corresponding to it are known, prohibiting the operation of disconnecting switches on and off when the connection switch i is turned on, containing disconnectors block-locks and breaker contacts.
Однако эти схемы не могут обеспечить необходимой безопасности оперативного персонала, так как они не предусматривают блокировку при оперировании обходными разъединител ми .However, these schemes cannot provide the necessary security for operational personnel, since they do not provide for blocking when operating bypass isolators.
Наиболее близким по техническому решению к предложенному вл етс устройство блокировки обходных разъединителей дл подстанций с двойной системой шин с шиносоединительнымThe closest to the technical solution proposed is a device for blocking bypass disconnectors for substations with a double busbar system with a bus connection
И обходным выключател ми, содержащее последовательно соединенные размыкающий блок-контакт обходного выключател , блок-контакты заземл ющих ножей обходной системы шин и соединенные параллельно через блок-контакты обходных разъединителей, после дователъные цепочки из блок-контактов заземл ющих ножей линейных разъединителей и блок-замков заземл ющих ножей обходной системы шин и обходных разъединителей |23.And bypass switches containing a series-connected disconnecting block contact of a bypass switch, blocking contacts of grounding knives of a bus bypass system and connected in parallel via blocking contacts of bypass disconnectors after the normal chains from the blocking contacts of grounding knives of linear disconnectors and blocking locks grounding knives of the bus bypass system and bypass disconnectors | 23.
Известное устройство позвол ет оперировать обходным разъединителем любого из присоединений при отключенных обходном выключателе , обходных разъединител х соседних присоединений и заземл ющих ножах разъединителей обходной системы шин.The known device makes it possible to operate a bypass isolator of any of the connections with the bypass switch off, the bypass disconnectors of the adjacent connections and the grounding knives of the bypass busbar disconnectors.
