Изобретение относитс к производству, преобразованию и распределению электрической энергии и может быть использсжано в устройствах дл определени степени компенсации емкостных токов сети относительно земли в высоковольтных сет х энергоснабжени , работающих с нейтралью, компенсированной дугогас щими аппаратами .The invention relates to the production, conversion and distribution of electrical energy and can be used in devices for determining the degree of compensation of capacitive network currents relative to the earth in high-voltage power supply networks operating with a neutral compensated by arc-suppressing devices.
Известен датчик степени компенсации емкостных токов электрической сети с заземленной через дугогас щий аппарат нейтралью , содержащий трансформатор тока дуегогас щего аппарата и измерительное устт ройство. A sensor is known for the degree of compensation of capacitive currents of an electrical network with a neutral grounded through an arc-suppressing device, which contains a current transformer of a deogas apparatus and a measuring device.
Однако известный датчик имеет невысокую точность замерсж при нормальном и . аварийном режимах.However, the known sensor has a low accuracy zamerszh under normal and. emergency modes.
Цель изобретени - обеспечить повышение точности измерений в нормальном и аварийном режимах.The purpose of the invention is to improve the accuracy of measurements in normal and emergency modes.
Это достигаетс благодар тому, что датчик содержит дополнительно фильтр токов нулевой последовательности, включенный встречно с трансформатором тока ду-J This is achieved due to the fact that the sensor additionally contains a zero-sequence current filter, connected in opposite with a current transformer dy-J

На чертеже приведена схема предлагаемого датчика степени компенсации.The drawing shows a diagram of the proposed sensor degree of compensation.
Датчик степени компенсации состоит из фильтра 1 токов нулевой последовательности (цепи трансформаторов тока включены параллельно), трансреактс а 2, первична цепь которого включена в одну из цепей между фильтром 1 токов нулевой последовательности и трансформатором 3 тока дугогас щего аппарата 4, включенным встречно фильтру токов нулевой последовательности и силового трансформатора 5.The compensation degree sensor consists of a zero-sequence current filter 1 (current transformer circuits are connected in parallel), transreact a 2, the primary circuit of which is included in one of the circuits between the zero sequence current filter 1 and the current transformer 3 of the arc-suppressor 4, which is connected to zero current filter sequence and power transformer 5.
Датчик работает следующим образом.The sensor works as follows.
При по влении несимметрии в сети на . фильтре токов нулевой последовательности 1 выдел етс ток 3 J . По вл ющеес при несимметрии напр жение смещени нейтрали вызывает протекание индуктивногр тока L по основной обмотке дугогас щего аппарата 4, выдел емого на трансформаторе 3 тока дугогас щего аппарата. Так как токи 31 и I направлены встречно, |When asymmetry appears on the network at. The zero sequence current filter 1 is supplied with a current of 3 J. The voltage of the neutral displacement appearing with asymmetry causes inductive current L to flow through the main winding of the arc-suppressor 4, which is separated on the transformer 3 of the arc-current. Since the currents 31 and I are directed oppositely, |

Предмет и.эобретени on transreactor 2, the magnitude is allocated, J is proportional to the degree of compensation of the capacitive current of the network relative to the ground .. The subject of the invention
Датчик степени компенсации емкостных токов лектрической сети с заземленной i через дугогас щий аппарат нейтралью, содержащий трансформатор тока дугогас щего аппарата и измерительное устройство, о тличающийс тем, что, с целью повышени точности измерений внормальном и аварийном режимах, он содержит фильтр. токов нулевой последовательности сети, включенный встречно с трансформатором тока Дугогас щего аппарата через трансреактор , выходы которого подсоединены к измерительному устройству. The sensor for compensation of capacitive currents of an electrical network with a grounded i through an arcing neutral device, contains an arcing unit current transformer and a measuring device, differing in that, in order to improve the accuracy of measurements in the normal and emergency modes, it contains a filter. network zero-sequence currents, connected in opposite with the current transformer of the arc-extinguishing apparatus through a trans-reactor, the outputs of which are connected to the measuring device.
