Abstract
A self contained, self charging automatic hydraulic activation mechanism (AHAM) for a superconducting energy magnetic storage (SMES) system is disclosed. The AHAM is operatively coupled to arc activated switches disposed across a superconducting coil to automatically close the switches upon a coolant dump. The arc activated switches are also self actuating and close in response to arcing across the switch contacts or across spark gaps provided on the switches.
