Description
ётсй вб ЁтбрйЧйЫе обмотки трансформатора св зи и циркулирует в контуре, образован-ном двум фазами сетевого трансформатора 4 и фильтрами несущей частоты 5, частично ответвл сь в нагрузку 3 сетевого трансформатора 2. Из обмотки низкого напр жени сетевого трансформатора 2 сигнал трансформируетс в .сеть среднего напр жени , где циркулирует в контуре, образованном двум фазами, обеспечива тем самым передачу информации по электрической сети.The windings of the communication transformer are circulating in the circuit formed by the two phases of the mains transformer 4 and the carrier frequency filters 5, partially branching into the load 3 of the mains transformer 2. From the low voltage winding of the mains transformer 2, the signal is transformed into the medium network voltage, where it circulates in a circuit formed by two phases, thereby ensuring the transmission of information through the electrical network.
Повышение стабильности уровн сигнала , вводимого в сеть, достигаетс за счет исключени вли ни изменени нагрузки сетевого трансформатора нутем шунтировани ее в двух используемых фазах фильтрами несущей частоты, а в третьей - нулевым проводом. Воздействие изменени сопротивлени сети среднего напр жени , в случае необходимости, исключаетс выбором величин сопротивлени вторичных обмоток трансформатора св зи, максимальна величина которых ограничена допустимым падением найр жени ма йромыШлёйной частоте.The increase in the stability of the level of the signal introduced into the network is achieved by eliminating the effect of changing the load of the mains transformer by shunting it in two phases used by carrier frequency filters, and in the third by the neutral wire. The impact of a change in the resistance of the medium-voltage network, if necessary, is excluded by the choice of the resistance values of the secondary windings of the transformer of the communication transformer, the maximum value of which is limited by the permissible drop in gravity of the junction frequency.
