(54) ЛИНИЯ ЭЛЕКТРОПЕРЕДАЧИ(54) ELECTRICAL TRANSMISSION LINE

В схеме (см.фиг.1) опоры 4, на которых производитс  трансшййци  тросхш Ii чередуютс  с опорами, на которых тросы эффективно заземлены, причем транспозици  осуществл етс  двум  перемычками.In the diagram (see Fig. 1), the supports 4, on which the transyjits of the wires Ii are made, alternate with the supports on which the cables are effectively grounded, and the transposition is carried out by two jumpers.

В схеме (см.фиг. 2) на опоре устанавливаетс  одна перемычка, но транспозици  осуществл етс  на каждой . Эффектна ность обеих схем одинакова выбор схемы при этом определ етс  конструктивными соображени ми и услсжи ми монтажа. Суммарные активные потери в системе тросы-земл  при применении указанных схем тросовой защиты незначительно отли: чаютс  от потерь в схемах с полной или частичной изол цией .тросов. Кроме того, за счет уменьшени  электромагнитной св зи между фазами услови  гашени  .In the diagram (see Fig. 2), one jumper is installed on the support, but the transposition is performed on each. The effectiveness of both schemes is the same choice of scheme, and this is determined by the design considerations and installation conditions. The total active losses in the cable-ground system when applying the mentioned cable protection schemes are slightly different: they are caused by losses in schemes with complete or partial insulation of cables. In addition, by reducing the electromagnetic coupling between the phases of the quenching condition.

При необходимости использовани  грозозащитных тросс в дл  передачи сигналов защиты н св зи в местах заземлени  тросе следует устанавливать заградительарые высокочастотные дроссели.recharge arcs with automatic restart (OAPV). This will improve the performance of the lines in non-single phase modes. If it is necessary to use ground lightning protection in order to transmit protection and communication signals, barriers should be installed at cable earthing points.

Предмет изобретени Subject invention

Лини  электропередачи переменнсго : тока, содержаща  заземленные грозозащитные тросы, отличающа  с   тем, I что, с целью снижени  активных потерь, i тросы транспонированы на участках линии между точками их заземлени  посредствса по крайней мере Однрй перемычки, подвешенной на изол торах и шунтированной искрсшыми промежутками.Variable power lines: containing grounded ground wire, characterized in that, in order to reduce active losses, i cables are transposed in the line sections between their ground points through at least one jumper wire suspended by insulators and shunt by sparks.
