Abstract
A self-recovering device current limiting device with liquid metal includes two solid metal electrodes for connecting to an electric circuit to be protected. Several compression chambers partially filled with liquid metal are arranged one after the other between the electrodes. The compression chambers are formed by pressure-resistant insulating bodies and insulating intermediate walls supported by the insulating bodies. The insulating bodies include several connecting channels. To adjust the current limiting device to a desired nominal current factor, the level of the liquid metal above the connecting channels can be modified using an adjusting device. A reservoir is connected to the adjusting device, which can be adjusted and fixed in place externally.
