Description

В основном авт. св. Л 83477 описано устройство дл  включени  н выключени  линий электропередач посто нного тока высокого напр жени , представл ющее собою короткозамыкающее приспособление с быстр()действуюи1им ра.ъединителем, который в момент замы1 ани  линии посто нного тока накоротко производит отключение места иовреждени .Basically auth. St. L 83477 describes a device for switching on and off DC power lines of high voltage, which is a short-circuit device with a fast () operating pa-connector, which, when the DC line is closed, short-circuits and damages the site.

Предметом насто щего изобретени   вл етс  устройство дл  селективного отключени  параллельных линий электропередачи посто нного ток-а, снабженных указанными выключател ми. Сущность изобретени  состоит в применении на каждой линии блокирующего устройства, которое при повреждении на данной линии позвол ет разъединителю отключить эту линию после срабатывани  короткозамыкающего приспособлени , но ботокирует размыкание разъединител  при повреждении на соседней линии.The object of the present invention is a device for the selective disconnection of parallel DC power lines equipped with the specified switches. The essence of the invention is to use a blocking device on each line, which, if damaged on this line, allows the disconnector to disconnect this line after the shorting device has tripped, but it locks the opening of the disconnector if the adjacent line is damaged.

На чертеже показана электрическа  схема головно части высоковольтной системы посто нного тока с выпр мительной подстанцией 7 и двум  параллельными лини ми электропередачи 1 и П.The drawing shows an electrical diagram of the head of a high-voltage DC system with a rectifying substation 7 and two parallel power lines 1 and P.

Выпр мительна  подстанци  J работает с константным токовым регул тором 2. Линии I и И снабжены высок()15ольтиыми выключающими устройствами посто нного тока с короткозамыкаюшими приспособлени ми 3; и 5.Г1 и разъединител ми, 4-. и 4:, рассчитанными на небольшую силу тока. Дл  обеспечени  правильной работы быстродействующего автоматического константного токового регул тора 2 и облегчени  работы разъединителей 4i и 4и между щинами и короткозамыкающими приспособлени ми включены части 5; и Оп индуктивностей сглаживающих дросселей 5, и бц . На каждой линии установлен измерительный трансформатор тока 7 ; и 7II..., действующи на устройство 8 ... отпирани  к. 3. ириспособлени  и управлени  разъединителем..The rectifying substation J operates with a constant current regulator 2. Lines I and I are equipped with high () 15-volt DC switching devices with short-circuit devices 3; and 5.G1 and disconnectors, 4-. and 4: designed for a small amperage. In order to ensure the correct operation of the fast-acting automatic constant current regulator 2 and to facilitate the operation of the disconnectors 4i and 4, parts 5 are included between the women and the shorting devices; and op inductances of smoothing chokes 5, and bc. A measuring current transformer 7 is installed on each line; and 7II ..., acting on the device 8 ... unlocking to. 3. and the arrangement and control of the disconnector ..

Нри коротком за.мыканип в линии 1 ток в линии I течет от щин, авлинииН (разр дный ток)-к щцнам. Противоиоложное обычномунанаиравлению тока в линии Н фиксируетс  ламповой схе.мой или быстродействующ .им пол ризованным реле,- имеющимс  в устройстве 8;; „ которое , разреша  отпирание короткозамыкающего устройства 3 одновреIn a short circuit break in line 1, the current in line I flows from the women, line A (discharge current) to the switch. The anti-current normal and the current in line H are fixed by a lamp circuit or by a fast-acting polarized relay, which is in device 8 ;; „Which, allowing the opening of the short-circuit device 3 at the same time
