Triggered High Current Opening Switch.
Abstract
This invention describes a means by which electric current of values up to many thousands of amps may be made to cease flowing at a precisely controlled point in time. A fuseable link is inserted in series-connection in the circuit, and load current causes resistive heating to a temperature less than the melting point. At a selected time, energy from some external source (laser, capacitor, etc.) is introduced into the fuseable link which causes melting and a rapid transition of temperature and resistivity until explosive vaporization of the fuseable link takes place. At that point, the flow of current is blocked. (Author)
