Abstract
Изобретение относитс к электротехнике и предназначено дл коммутации цепей переменного тока. Цель изобретени - повышение надежности гибридного контактора При включении контактора блок 8 определени характера нагрузки определ ет индуктивность нагрузки 3, что позвол ет производить включение полупроводникового ключа 2 в момент ожидаемого перехода тока в цепи нагрузки 3 через нулевое значение При этом исключаютс броски тока, возникающие при подключении индуктивной нагрузки к источнику питани в произвольный момент времени. Затем замыкаютс силовые контакты 1. При отключении нагрузки сначала подаетс команда на включение полупроводникового ключа 2, затем размыкаютс силовые контакты 1, после чего при первом переходе тока через нуль ключ 2 запираетс . 3 ил.The invention relates to electrical engineering and is intended for switching alternating current circuits. The purpose of the invention is to increase the reliability of the hybrid contactor. When the contactor is turned on, the block 8, determining the nature of the load, determines the inductance of the load 3, which makes it possible to turn on the semiconductor switch 2 at the moment of the expected current transfer to the load circuit 3 through zero. inductive load to the power source at an arbitrary point in time. Then the power contacts 1 are closed. When the load is disconnected, the command to turn on the semiconductor switch 2 is first given, then the power contacts 1 are opened, after which the first time the current passes through zero, the switch 2 is locked. 3 il.
