Inventor: MASUMOTO RYO
IPC: H01C7/06
Filed: 1987-10-24
Abstract: PURPOSE:To develop a Pd-Fe alloy material of which the electric resistance changes little in a specific temp. range and which has excellent workability by quickly cooling a Pd-Fe alloy having a specific compsn. from a specific temp. and cold working the alloy to a sheet, wire rod, etc., then covering the material with a heat resistant insulating material and subjecting the material to a heat treatment under specific conditions in a nonoxidative atmosphere. CONSTITUTION:The Pd-Fe alloy consisting of 59-88% Pd and the balance Fe is smelted and the ingot thereof is cold worked by swaging to the wire rod having 5mm diameter. After the wire rod is subjected to the homogenization treatment at 1,150 deg.C in a vacuum and is then quickly cooled from the temp. above the regular-irregular transformation temp. (570 deg.C) and above the m.p. of this alloy down to an ordinary temp. The wire rod is then cold drawn at need to a fine wire having 0.5mm diameter and is embedded into the heat resistant insulating material of silica, alumina, etc., or is formed with the heat resistant insulating film thereon, thereafter, the wire is annealed by holding the wire for 2sec-100hr at the temp. between the regular-irregular transformation temp. and the m.p. in the nonoxidative atmosphere or vacuum and cooling the same at 5-300 deg.C/hr cooling rate.

IPC: H02J3/38
Filed: 1987-10-26
Abstract: PURPOSE:To discriminate inverse power transmission and outbreak of short- circuit accident from inverse power stop and outbreak of ground-fault accident by placing a directional relay with minor power on the secondary side of a transformer, tripping a breaker on the secondary side of the transformer, and at the same time, making operation and non-operation of an overcurrent relay placed on the primary side of the transformer. CONSTITUTION:When a breaker 1A for distribution of a power company is opened, a transformer 10 is excited reversely by a non-utility generator power, and transmission lines of the power company is reversely pressurized. At this time, the reverse excitation current from the secondary side of the transformer 10 is detected by a power directional relay 11 with minor power, and a breaker 1B for receiving power is tripped. Accordingly, the reverse pressurization of transmission lines on the company side can be prevented. When a ground-fault accident occurs in transmission lines on the company side, it is detected by a ground-fault overcurrent relay 3A for distribution of the power company, and the breaker 1A for distribution is tripped. The same as in the above- mentioned case, it in enough to use the power directional relay 11 with minor power for the detection, and trip the breaker 1B or 1C.

CONSTITUTION:In an ice accumulation operation, a brine passage switching valve 6 is opened, a valve 5 is closed to guide the low temperature brine of a chiller unit 1 to the icing heat exchanger 9 of a heat accumulation tank 2, to further circulate it to be returned to the unit 1 via a brine pump 4 to cool water in the tank 4, thereby icing the outer periphery of the tube of an icing heat exchanger 9. A temperature detector 11 is provided in the heat accumulation tank outlet pipe 8a, and when it detects 20mm of ice thickness as heat accumulation end, the brine temperature at the outlet of the tank 2 is -5.7 deg.C. Thus, a temperature switch 12 is so set as to turn OFF the unit 1. When the ice thickness becomes 20mm, the heat accumulation operation is finished, the accumulation end can be accurately determined to prevent the operating efficiency from decreasing due to excessive icing or its structure from damaging.
