Description
В основном авт. св. № 127322 описано устройство дл коммутационных перенапр жений в дальних передачах при помощи шунтирующего трехфазного двухобмоточного реактора, вторичные обмотки которого замкнуты в треугольник.Basically auth. St. No. 127322 describes a device for switching overvoltages in long-distance transmissions by means of a shunt three-phase two-winding reactor, the secondary windings of which are closed in a triangle.
Предлагаемое устройство вл етс дальнейшим развитием и усовершенствованием устройства по авт. св. ЛЬ 127322 и отличаетс тем, что, с целью уменьшени потреблени реактивной мошности при нормальной нагрузке линии, в цепи вторичных обмоток включен выключатель , импульс на включение которого подаетс одновременно с отключением защищаемой линии или силового трансформатора на потстанции .The proposed device is a further development and improvement of the device according to the author. St. L27322 is characterized in that, in order to reduce the consumption of reactive power during normal line load, a circuit breaker is turned on in the secondary windings circuit, the pulse for which is turned on simultaneously with the disconnection of the protected line or power transformer at the station.
На чертеже изображена схема включени предлагаемого устройства.The drawing shows the circuit of the proposed device.
Дл снижени коммутационных перенапр жений к линии дальних передач / подключаетс реактор, первична обмотка 2 которого подключаетс параллельно линии, а вторична обмотка 3 при помощи выключател 4 может быть замкнута накоротко.To reduce switching overvoltages, the long-distance transmission line connects the reactor, the primary winding 2 of which is connected in parallel to the line, and the secondary winding 3 can be short-circuited using switch 4.
В нормальном режиме выключатель разомкнут, чем уменьшаетс потребление реактивной мощности в линии, а при отключении линии он замыкаетс , что уменьшает величину перенапр жени .In normal mode, the switch is open, which reduces the consumption of reactive power in the line, and when the line is disconnected, it closes, which reduces the amount of overvoltage.
Импульс на включение закорачивающего выключател подаетс одновременно с отк.лючением защищаемой линии или силового трансформатора на подстанции.The impulse to turn on the shorting switch is supplied simultaneously with the opening of the protected line or the power transformer at the substation.
При включении вторичных обмоток защитного трансформатора в треугольник можно вместо трехполюсного использовать двЗхполюсный выключатель, а в случае включени вторичных обмоток заземленной звездой можно примен ть выключатели без опорных изол торов.When the secondary windings of the protective transformer are triangularly connected, a two-pole switch can be used instead of a three-pole one, and if the secondary windings are connected with a grounded star, one can use breakers without reference insulators.
