Abstract: A self-recovering current-limiting device with a liquid metal includes two T-shaped electrodes for connection to an electric circuit to be protected. Each of the electrodes are made of a solid metal. Several compressor cavities which are partially filled with the liquid metal are situated one behind the other between the electrodes. The compressor cavities are formed by pressure-proof insulating bodies and by insulating intermediate walls which are provided with connecting channels and which are held by the insulating bodies. The insulating bodies and the intermediate walls form a uniform upper and lower half shell with opposite-lying joining surfaces. The half shells are connected in a sealed manner along joining surfaces in the area of a common middle plane of the connecting channels. Up to half of each of the electrodes is accommodated in corresponding recesses of the half shells, the electrodes extending with their respective middle limb out of the half shells.

Abstract: A self-recovering current-limiting device having liquid metal includes solid metal electrodes for connecting to an external electric circuit to be protected. A plurality of compression spaces which are partially filled with liquid metal are arranged one behind the other between the electrodes and are formed by pressure-resistant insulating bodies and by insulating partitioning walls having connecting channels. An enclosing insulating shaped housing is provided having a trough-like bottom part and a cover that tightly closes the bottom part via a non-positive and/or positive connecting device. The partitioning walls and the bottom part are interconnected as one piece. The connecting channels are configured as longitudinal holes which are open at the top. The electrodes are mounted in the bottom part. The nominal current range of the device may be easily adjusted.

Abstract: A self-regenerating current limiter with liquid metal includes solid metal electrodes for connection of the current limiter to an electric circuit to be protected. A plurality of compression chambers that are partially filled with liquid metal are located one behind the other between the electrodes. The compression chambers are formed by compression-proof insulating bodies and insulating partition walls that have communicating channels and that are supported by the insulating bodies. Non-conductive ceramic disks are mounted on the inner surfaces of the electrodes. The disks are located opposite the communicating channels of the adjacent partition walls.

Abstract: A current limiting device including a housing in which a chamber is formed. A pair of spaced electrical terminals are located at opposite ends of the housing to be disposed in communication with the chamber. An electrically conductive fusible metal is disposed in the chamber to provide an electrically conductive path between the terminals. An insulating member is disposed in the chamber between opposite ends of the housing to define a flow passageway between the electrical terminals. The flow passageway may include a constricted portion that has a cross-sectional area and a length that is substantially less than the rest of the flow passageway defined by the insulating member such that with the occurrence of a fault current, vaporization of the fusible metal initially occurs in the constricted portion of the flow passageway. Expansion means are also provided for buffering the pressure rise in the chamber when the fusible metal is vaporized.
