专利名称：SURGE VOLTAGE PROTECTION SYSTEM发明人：JAMES M. CONSTABLE申请号：US3678341D申请日：19700805公开号：US3678341A公开日：19720718
摘要：Protection against surge voltages, particularly in high power applications suchas electron welding systems, is provided by causing a pair of electrical conductorscarrying current in opposite directions to pass through a toroid of high magneticpermeability, that toroid producing a high inductance in those lines without saturating,that inductance acting in conjunction with protective capacitors connected across thelines so as to minimize the surge voltages produced by short circuits or otherabnormalities in the overall system.
