摘要： PURPOSE:To protect by suppressing the overvoltage at ground-fault defect time by dividing a thyristor series unit into a plurality of sets by main circuit points, connecting the shield of the thyristor with the points, and connecting nonlinear resistors between the points. CONSTITUTION:A plurality of thyristors THY are connected in series, and divided into a plurality of sets by a plurality of main circuit points M1-Mn-1 which includes both ends P and W2. A plurality of shields SD disposed to surround the potential of the thyristors THY are connected with the main circuit points P-Mn-1. Further, nonlinear resistance elements A1-An are respectively connected between the points P-W2 to form thyristor valve 5. Thus, even if the charging voltage of the ground capacity of the shield SD is applied due to the ground fault defect, the thyristors can be protected.

摘要： PROBLEM TO BE SOLVED: To provide a current limiter which is simple in structure and is inexpensive. SOLUTION: A current limiter, which is connected in series to a power system and suppresses an overcurrent flowing load, is equipped with first and second coils, which are electrically connected in series to have negative magnetic coupling state, a breaker which is connected in series to the above second coil, a short circuit line which is connected in parallel to the unit connected in series of the above second coil and the above breaker, and an overcurrent detector which detects the current flowing to load and opens the above breaker at detection of overcurrent at or higher than the prescribed value. This current limiter suppresses an overcurrent by the high impedance first coil, by opening the breaker, when an overcurrent at or higher than the prescribed value flows to the load, thereby short-circuiting the unit connected in series of the second coil and the breaker, to allow the current to the first coil and the short circuit line, and also prevents the occurrence of arc in the breaker.

摘要： PURPOSE:To reduce the loss head of a cooling gas flow circulating through a thrystor module by a method wherein an insulating support for installing the lowest stage thrystor module on the bottom of a tank and a roughly horizontal air passage running from a side wall of the insulating support to the wind outlet of a blower are provided. CONSTITUTION:A cylindrical, insulating support 11 supporting a piled thrystor module 1 extends to the bottom of a lower tank 4 whereon it is fixed secure. On the insulating support 11, a cylindrical wind tunnel 11a is formed, protruding orthogonally to the side of a branch tubing 8 of the lower tank 4. An insulating cylinder 13 is fixed tight by a bolt to the flange of the branch tubing 8, connected to the flange of a wind outlet 12 of a blower 7, belonging to the lower tank 4. On the outer circumference of the inner end of the insulating cylinder 13, an O-ring is provided, to ensure airtightness between the insulating cylinder 13 and the cylindrical wind tunnel 11a of the insulating support 11. The opening of the cylindrical wind tunnel 11a is roughly similar, in diameter d4, to the opening of the wind outlet 12 of the blower 7. The inner diameter of the insulating support 11 is d1, as in the conventional design. Accordingly, the loss head of the coolant gas flow is reduced.

摘要： PURPOSE:To provide an inexpensive and mechanically strong superconducting coil by disposing a spacer for a cooling channel among winding layers and performing winding, and thereafter performing a high temperature heat treatment for production of a superconducting material, and further impregnating a resulting winding with epoxy resin. CONSTITUTION:A compound superconducting wire 2 is wound to yield a superconducting coil 1 by a wind-and-react method. A spacer 11 for a cooling channel to construct the coiling channel is arranged among winding layers of the superconducting coil 1. A spacer 11 structure is constructed with an insulating material 12 formed by knitting into a bag shape heat resistant fibers, e.g. ceramics aluminum fibers and with a metal piece 13 comprising stainless steel for example inserted into the interior of the insulating material 12 for resisting a high temperature heat treatment and reinforcing the spacer. The spacer 11 is disposed among the winding layers and winding is performed, and thereafter the high temperature heat treatment is performed to produce a superconducting material. Thereafter, the resulting coil is impregnated with epoxy resin 14. Hereby, the inexpensive and mechanically strong superconducting coil 1 is yielded.
