摘要： PROBLEM TO BE SOLVED: To prohibit erroneous outputting of a trip signal by detecting data failure, even if a failure occurs with a memory circuit. SOLUTION: The protective relay comprises an input converter, to which a system electric quantity is introduced, a filter which introduces the output of the input converter, a conversion circuit which samples the output of the filter by a prescribed time interval and converts it into digital data, and a digital calculation part which performs protection relay calculation with the digital data. It also comprises duplexed first memory circuit and second memory circuit which allow reading/writing of the calculated data and deciding result, a memory selection circuit which separately reads each of the memory circuits, and a monitor means which determines the presence of abnormalities in memory data by comparing the data which are read, and outputs a trip signal, only when a digital relay is normal.

摘要： PROBLEM TO BE SOLVED: To provide an electric appliance monitoring and controlling system which reduces patrol maintenance work to a temperature controller by allowing the temperature controller to detect its state by itself and allowing a management center to integrally manage the information thus detected, and also provide a method therefor. SOLUTION: A control command for controlling the temperature controller 23 from a centralized management center 10 is received by a control device 21, and the setting temperature of the temperature controller is changed based on the control command. Then, the temperature controller 23 receives information on consumed electric power and reaching time, which are required to reach the setting temperature, and transmits the information to the centralized management center 10. The centralized management center 10 requires the maintenance of the temperature controller 23 when the information on the electric power consumption or the reaching time reaches a prescribed threshold level.

摘要： PROBLEM TO BE SOLVED: To provide a lamp wick breakage detection/processing device capable of securing safety of a personnel for maintaining and exchanging a lamp and improving efficiency of a maintenance work. SOLUTION: A voltage generating part 22 is serially connected to a bypass circuit 15 closing when the wick of the lamp 12 is broken. The voltage generating part 22 makes current from a secondary side of a current transformer 11 flow and generates a prescribed voltage when the wick of the lamp 12 is broken and the bypass circuit 15 is closed. An arithmetic control circuit 14 determines that the breakage of the wick of the lamp 12 is restored, when a current detection circuit 16 detects a current flowing through the lamp 12 by the voltage of the voltage generating part 22, while a contact 15a of the bypass circuit 15 is closed. Accordingly, high voltage is never to be generated when restoring of the breakage of the wick of the lamp 12. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To perform highly accurate automatic monitoring by comparing the dissipation current of a dot-matrix display device, when the display data of a test display pattern is outputted with the specified value and judged. SOLUTION: This display device is constituted of a display device 6, having a memory 2 storing display data, an X-driver 4 and a Y-driver 3 driven by the memory 2, a dot-matrix display device 5, which performs light emission by the drivers 4 and 3, and an interface CPU 1 for performing the interface of the control of the memory 2 and the outside, and a host CPU 8 for controlling the device 6. Furthermore, the dissipation current of the display device 5 is measured with a current measuring part 7 and outputted to the CPU 8. The display device 5 is made to set for the test-pattern display by the CPU 8. Whether or not the display of the test pattern is obtained can be judged by accepting the current-charging amount at this time, from the output of a measuring part 7. Therefore, the inspection by an inspecting person is not required, and the automatic monitoring of the judgment of the presence or absence of the fault of the display device can be performed.

摘要： PURPOSE:To provide information necessary for maintenance and inspection and decision on the life of power equipment accurately, by arranging a current transformer, an AC-DC conversion circuit, an arithmetic circuit, an electrochemical element, a detection circuit and a means of informing externally to memorize the sum of breaking current of an overload current breaker in a power system for a long time. CONSTITUTION:When an AC current i1 is applied to a current transformer 1, an AC current i2 is obtained in the secondary side of a current transformer 1 and converted into DC I with an AC-DC conversion circuit 2. The DC I is introduced into an arithmetic circuit 3 with which a specified value IOF is subtracted from the DC I, where the specified value IOF is a DC signal equivalent to a value by which the current i1 is determined to be overcurrent. An output IM of the circuit 3 runs to an electrochemical element 4 only while the current ii exists as overcurrent to cause a precipitation of a mass (m) within the element 4 on an electrode 4b facing it only in the amount equal to that of the current. As the amount of the mass once precipitated retains as intact unless the polarity is reversed in the current IM flowing through the element 4, the storage and memorization of the amount of current is made possible. Then, a potential VM between electrodes of the element 4 rises sharply and is detected 5 to be displayed 6.
