Description
Цель изобретени - исключение коронировани троса и улучшение грозозащитных свойств линии.The purpose of the invention is to exclude the corona of the cable and improve the lightning protection properties of the line.
Это достигаетс тем, что предлагаема лини дополнительно снабжена полупроводниковыми элементами, например вентил ми, которые включены параллельно искровым промежуткам .This is achieved by the fact that the proposed line is additionally equipped with semiconductor elements, for example, valves, which are connected parallel to the spark gaps.
Предлагаема лини электропередачи изображена на чертеже.The proposed power line is shown in the drawing.
Она содержит фазные провода линии электропередачи 1, грозозащитные тросы 2, искровые промежутки (разр дники) 3 и вентили 4.It contains the phase conductors of power line 1, ground wire 2, spark gaps (gaps) 3 and valves 4.
Предлагаема лини электропередачи работает следующим образом. Продольна электродвижуща сила (э.д.с.), возникающа на тросе за счет емкостной св зи троса с фазными проводами, шунтируетс вентил ми лишь в том случае, если пол рность э.д.с. имеет отрицательный знак, и трос остаетс под потенциалом , если наводима э.д.с. имеет положительную пол рность.The proposed power line works as follows. The longitudinal electromotive force (emf) arising on the cable due to capacitive coupling of the cable with the phase wires is only shunted by the valves if the polarity of the emf. has a negative sign and the cable remains under potential if the emf is induced. has a positive polarity.
При грозовых перекрыти х, имеющих в основном отрицательную пол рность, срабатывают искровые промежутки, а положительный потенциал на тросах улучшает грозозащиту линии.With thunderstorms, which have mostly negative polarity, spark gaps are triggered, and the positive potential on the cables improves the lightning protection of the line.
Таким образом, на тросе не накапливаетс отрицательный зар д, при котором и происходит коронирование тросов, а следовательно , и генерируютс помехи.Thus, a negative charge does not accumulate on the cable, at which the cables are crowned and, therefore, noise is generated.
Наличие лишь положительного пульсирующего потенциала на грозозащитных тросах способствует самопогасанию дуги, и кроме того, улучшает грозозащитные свойства линии .The presence of only a positive pulsating potential on the ground-wire cables contributes to the self-extinguishing of the arc, and in addition, improves the lightning-protective properties of the line.
