Abstract
Устройство для измерения тока и напряжения в высоковольтной сети, работающего на принципе масштабного преобразования тока и напряжения с дальнейшим аналого-цифровым кодированием величин тока и напряжения на высоком потенциале сети с последующим излучением кодированной информации об измеренном токе и напряжении на сторону низкого потенциала по изолированному оптическому каналу, с питанием компонентов, находящихся на высоком потенциале сети от быстронасыщающегося трансформатора тока, включенного в высоковольтную сеть, отличающееся тем, что быстронасыщающийся трансформатор тока содержит дополнительную обмотку, подключаемую при отсутствии тока в высоковольтной сети триггерным устройством между высоковольтной сетью и высокоомным делителем напряжения, служащим одновременно и масштабным преобразователем напряжения.A device for measuring current and voltage in a high-voltage network, operating on the principle of scale conversion of current and voltage with further analog-to-digital coding of current and voltage values at a high potential of the network, followed by the emission of encoded information about the measured current and voltage to the low potential side through an isolated optical channel , with the power supply of components located at high network potential from a rapidly saturable current transformer included in a high-voltage network, characterized the fact that the rapidly saturable current transformer contains an additional winding connected in the absence of current in the high-voltage network by a trigger device between the high-voltage network and the high-resistance voltage divider, which simultaneously serves as a large-scale voltage converter.
