SYSTEM AND METHOD FOR SYNCHRONIZED RAPID SHUTDOWN OF ELECTRICAL DEVICES

摘要

In one embodiment, the invention can be a system for simultaneously shutting down electrical device, the system including a plurality of circuits, each circuit including an electrical device, and a control circuit configured to turn the electrical device on and off, each control circuit comprising an isolation transformer; an electrical source providing a control current; a switching device configured to switch on and off; and conductors configured to connect the isolation transformers of the plurality of circuits, the electrical source, and the switching device in series to form a current loop, the current loop transmitting the control current; wherein when the switching device is switched from on to off, the isolation transformers of the plurality of circuits stop receiving the control current, thereby causing the electrical devices of the plurality of circuits to shut off simultaneously.
