Surge arrestor unit

摘要: A three-terminal surge arrestor unit employs air gaps augmented with semiconductors to protect a circuit having two ungrounded conductors. Conductive electrodes and the are mounted on common axis in sandwich arrangement secured fixed relative positions. Two gap lightning arrestors provide current paths for respective conductors ground response strikes or other damaging surges, an equalizer is incorporated electrode configuration establish path between them from excessive voltage differential. The resulting single, designed replace multiple systems gas tube arrestors.
