A through hole 25 is arranged in the bottom plate 23 of the compression chamber 5, and a guide rod 27 is arranged so as to lead to the compression chamber 5 by passing penetratingly through the through hole 25. A moving plate 26 to compress gas is arranged in the compression chamber 5. A pressing spring 29 to press the moving plate 26 is arranged on the compression side. The pressing spring 29 and the moving plate 26 are constituted so as to be movable by compressing the pressing spring by means of the movable plate according to the gas pressure in the compression chamber 5 in the case of breaking operation.

摘要： PURPOSE:To improve safety and reliability by cooling a superconductor with gas thereby preventing explosive evaporation of liquid refrigerant upon quenching. CONSTITUTION:Gas 8 is cooled below the critical temperature of a superconductor 1 through a cooler 4 and cools the superconductor 1. A container 5 is provided with a safety valve 6 in order to cope with pressure rise. The container 5 is provided with a vacuum layer 7 at the outside thereof. The superconductor 1 converts to a resistor, upon quenching, to produce heat but when a circuit breaker functions, it is cooled with the cooling gas 8 and converted into a superconductor. Since liquid refrigerant is not employed, accident due to explosive evaporation of liquid refrigerant can be prevented even when the circuit breaker does not function.

摘要： PURPOSE:To increase the resistance value after quenching and improve the cooling efficiency, in a current-limiting element manufactured by using ceramic superconductor, by calcinating a wire so as to form a nonconductive type after melting the sheath of the wire which has been temporarily sintered by using the sheath such as of silver. CONSTITUTION:A current limiting element is formed by binding a wire by melting and sintering the wire after temporarily sintering and compacting the wire by using a copper or silver sheath. A ceramic superconductor is once temporarily sintered to compound a superconductor 1, which is molded and further sintered. After temporarily sintering and molding the wire in a copper or silver sheath, the sheath is melted by nitric acid or the like to produce a bare wire, which is sintered to produce a long element without sheath. Next, the wire is binded to get a required sectional area and fixed on an insulating plate 2 in nonconductive winding. Thereby, the long current limiting element can be obtained, the cooling efficiency is excellent because of the large sectional area of the wire contacting liquid nitrogen, the quick transfer to superconducting from normal conducting after recovering short-circuit fault becomes possible, and the circuit can be reclosed at high speed.

摘要： PURPOSE:To obtain the economical non-contact breaker of a miniature type, by connecting a plurality of the series connecting units of superconducting current-limiting wires and semiconductor breaking sections in parallel with each other. CONSTITUTION:Superconducting current-limiting wires 2a, 2b, 2c and semiconductor breaking sections 1a, 1b, 1c are respectively connected in series, and the series-connected ones are connected in parallel with each other to compose circuits. At the time of the generation of an accident, current to a circuit A is interrupted, and when current is fed to a circuit D, then a magnetic field is worked on the superconducting current-limiting wire 2a or a temperature is heightened, and the wire 2a is turned normally conductive and the current is limited, and after that, breaking command is issued to the semiconductor breaking section 1a. After that, the semiconductor breaking section 1b of the circuit U is closed. The superconducting current-limiting wire 26 of the circuit D is kept in a superconducting state, and so the circuit is quickly closed again.
