Изобретение относитс к электрическим сет м высокого напр жени .This invention relates to high voltage electrical networks.
Известны линии электропередач высокого напр жени с тросами и статическими конденсаторами дл снижени тока в тросах. В тех случа х, когда э.д. с., наводима в тросах током короткого замыкани , мала, включение конденсаторов в рассечку тросов нецелесообразно . Однако при наличии ла лини х двух грозозащитных тросов параллельное соединение тросов, которое примен ют дл снижени затухани высокочастотных сигналов, приводит к созданию дополнительного замкнутого контура «трос-трос.High voltage power lines with cables and static capacitors are known for reducing the current in the cables. In those cases, when ed. with., induced in the cables short-circuit current, small, the inclusion of capacitors in the dissection of the cables is impractical. However, in the presence of two lanes of lightning cables, parallel connection of cables, which is used to reduce the attenuation of high-frequency signals, leads to the creation of an additional closed loop cable-to-cable.
При отсутствии транспозиции проводов в тросах индуктируютс значительные э. д. с., неодинаковые между собой, вследствие чего ino контуру «трос-трос посто нно протекает ток и возникают дополнительные потери электрической энергии в активном сопротивлении тросов.In the absence of wire transposition in cables, significant e will be induced. D. s., unequal among themselves, as a result of which the ino contour “cable-cable is constantly flowing current and there are additional losses of electrical energy in the active resistance of the cables.
Целью изобретени вл етс ограничение а в тросах при наличии на линии двух тро повыгнение надежности передачи. -. достигаетс тем, что конденсаторы тены по концам линии между тросаптированы разр дниками, а каждый чрм из концов линии заземлен. оиства изображена на чертеже, озащитный трос линии высокого напр жени ; 2 - ъ. ч. заградитель; 3 - анкерное крепление троса на изол торах; 4- подвеска троса на изол торах на промежуточных опорах; 5 - шунтирующий искровой промежуток; 6 - статический конденсатор; 7 - защитный промежуток или разр дник.The aim of the invention is to limit a in cables if there is a two-way transmission reliability on the line. -. This is achieved by the fact that the capacitors of the tena are terminated at the ends of the line between the arresters, and each loop from the ends of the line is grounded. The cable is shown in the drawing, a high-voltage defensive cable; 2 - ъ. h. zagraditel; 3 - anchor fastening of a cable on insulators; 4- suspension of the cable on insulators on intermediate supports; 5 - shunt spark gap; 6 - static capacitor; 7 - protective gap or gap.
Тросы соединены на концах между собою последовательно через статические конденсаторы , емкостное сопротивление которых выбираетс таким образом, чтобы снизить до возможпого минимума протекание по тросам токов промышленной частоты и обеспечить протекание токов в. ч. св зи. Дл защиты конденсатора от распростран ющихс по тросу импульсных перенапр жений параллельно емкости включаетс защитный промежуток или вентильный разр дник.The cables are connected at the ends between themselves in series through static capacitors, the capacitance of which is chosen in such a way as to reduce the flow of industrial frequency currents through the cables and to ensure the flow of currents. h. communication To protect the capacitor from impulse overvoltages spreading along the cable in parallel with the capacitor, a guard gap or valve arrester is turned on.
