Abstract

PURPOSE:To surely detect a leakage and also, to enable to monitor soundness of detecting circuit including a detector, by conducting an electric current in the detecting circuit including a core wire always and also, detecting earthing of the circuit by leaked sodium. CONSTITUTION:An earthed sodium piping 1 and a core wire 2b applied a voltage of low-voltage power source of alternating current 3d, are insulated by an insulating material 2a in the state where sodium does not leak. When leakage happens, the wire 2b and piping 1 is made to the same electric potential and an earthing electric current circulating the leakage point of sodium and the neutral point of the source 3d flow. Then, an electric supply is broken by a leak breaker 3a and also, a leak pilot lamp 3b is lighted. Further, a power source pilot lamp 3c connected with the wire 2b in series, is lighted at ordinary times. Hereby, the leakage is detected surely and the soundness of the wire 2b and a cable 4, can be comfirmed always.
