    摘要: 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.

    摘要: 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.

    摘要: A short-circuit recognition method is disclosed, especially an early short-circuit recognition method, for an electric network. In at least one embodiment, in order to improve the switching times of protective devices, the current and the first and second temporal derivation thereof are continuously and consecutively determined at the same time and in the same temporal distance and are processed as respective digital sequences of numbers. Every sequence of numbers is associated with a defined threshold value, the numbers of the three sequences of numbers being compared with the respective threshold value associated therewith. Every number that exceeds the threshold value associated therewith is associated with a weighting variable and the weighting variables that pertain to the same time are added up to a first weighting sum. The first weighting sums are added to a second weighting sum for a defined number of directly subsequent times and the second weighting sum is compared with an additional defined threshold value. When the second weighting sum exceeds the defined threshold value, a short circuit is recognized.
