Abstract
Способ активного заземления нейтрали силового трансформатора через защитный модуль, заключающийся в том, что при отсутствии геомагнитной активности создают режим глухозаземленной нейтрали, а в период геомагнитных бурь создают режим изолированной нейтрали и контролирует напряжение нейтрали, включая защитный модуль, если напряжение достигает предельно допустимого значения, отличающийся тем, что защитный модуль выполняется в виде встречно-параллельно соединенных тиристоров, на управляющие электроды которых подают управляющие импульсы при отсутствии геомагнитной активности и прекращают подачу управляющих импульсов в периоды геомагнитных бурь.The method of active grounding of the neutral power transformer through the protective module, which consists in the fact that in the absence of geomagnetic activity they create a dead-grounded neutral mode, and during the period of geomagnetic storms create an isolated neutral mode and control the neutral voltage, including the protective module, if the voltage reaches the maximum permissible value, different the fact that the protective module is made in the form of counter-parallel connected thyristors, on the control electrodes of which they feed the control pulse s absence geomagnetic activity and stopping supplying control pulses during geomagnetic storms.
