Изобретение относитс к электротехнике , а именно к способам дистанционного управлени средствами коммутации в сет х распределени электрической энергии и предназначено, в частности, дл передачи команды от поврежденного присоединени на отключение выключател линии электропередачи (ЛЭП).The invention relates to electrical engineering, in particular, to methods for remote control of switching facilities in electrical power distribution networks and is intended, in particular, for transmitting a command from a damaged connection to disconnecting a power line switch (PTL).
Известен способ телеотключени выключател линии электропередачи, заключающийс в том, что при срабатывании релейной защиты поврежденного присоединени , модулируют напр жение несущей частоты напр жением промьшленной частоты, синхронным с напр жением данной электрической сети, передают фазу напр жени модул ции на другой конец и сравнивают фазу прин того сигнала с фазой напр жени промышленной частоты, синхронного Снапр жением приемного конца ЛЭП .A known method of tele-disconnecting a power line switch, which means that when a relay connection fails, the carrier voltage is modulated with an industrial frequency voltage synchronous with the voltage of this electrical network, the modulation voltage is transferred to the other end, and the received phase is compared In addition, a signal with a voltage phase of industrial frequency, synchronous, is supplied by the receiving end of the power transmission line.
Однако необходимо использование сложной и дорогосто щей аппаратуры, что понижает надежность работы устройства .However, it is necessary to use complex and expensive equipment, which reduces the reliability of the device.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ телеотключени выключател линии электропередачи , заключающийс в том,что при срабатывании репейной повto режденного присоединени ,запускают передатчик телеотключени , передающий сигнал заданной частоты и уровн по каналу св зи приемнику в месте установки выключател , после чего The closest to the invention in technical essence and the achieved result is the method of tele-disconnecting the power line switch, which means that when a burdock repetition connection is triggered, the tele-off transmitter, transmitting a signal of a given frequency and level over the communication channel to the receiver at the switch installation site then
1$ производитс отключение выключател 2.$ 1 off switch 2 is turned off.
Недостатком этого способа вл етс низка его надежность.The disadvantage of this method is its low reliability.
Цель изобретени - повышение его надежности.The purpose of the invention is to increase its reliability.
