FIELD: electrical apparatuses. ^ SUBSTANCE: proposed self-recovering liquid-metal current limiter characterized in enhanced reliability of its mechanical design and switching capacity has insulating bushing of heat-resistant ceramics provided with channel filled with liquid metal; it also has piston, two contact leads, and heat-resistant electrode. Core of the latter has its sectional area smaller than that of liquid metal channel and linear resistance of heat resistant electrode is lower than that of channel liquid metal. ^ EFFECT: enhanced reliability and disconnecting capacity of current limiter. ^ 1 cl, 1 dwg
