Automatic crowbar and arc quenching system |
摘要 |
A crossed-field switch device is connected in parallel to a load device which may arc. The characteristics of the crossed-field switch device are that it will not conduct when a high voltage is applied, but when the load device arcs, the crossed-field switch device conducts, taking current from the arc so that the arc quenches. The crossed-field switch device thus is a crowbar which is automatically conductive when the applied voltage decreases due to a line or load short.
