    摘要: A modular current interrupt device includes an electrically-conductive rupture disc, an electrically-conductive pressure disc attached to the rupture disc to form an electrical pathway. An electrically-insulating ring partitions a perimeter of the rupture disc from a perimeter of the pressure disc, and a seating element secures the electrically-insulated ring to the pressure disc. At least one of the rupture disc and electrically-insulating ring defines a conduit, whereby exposure of one side of the pressure disc to sufficient force through the conduit causes the pressure disc to separate from the rupture disc to thereby sever the electrical pathway. A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure in a range of, for example, between about 4 kg/cm2 and about 9 kg/cm2. Preferably, the CID includes a pressure disc that includes a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end, with a cross-section of at least one of the first and second end being non-circular.

    摘要: A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure. Preferably, the CID includes a first conductive plate and a second conductive plate in electrical communication with the first conductive plate, the electrical communication between the first and the second conductive plates being interrupted at the minimal threshold internal gauge pressure. The first conductive plate can include a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end, and the second conductive plate is in electrical contact with the essentially planar cap through a weld.
