Self-regenerating current limter with liquid metal

摘要

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.
