    摘要： The number of hidden layers is no larger than 2 and a sum is determined for each case. A relationship between the sum of the inputs and teaching data for each case is expressed in a table in a descending order of the sum of inputs for each output of an output layer, and the teacher data for the maximum sum and the number of times of change in the teacher data are considered. A configuration (the number of hidden layers and the number of neurons thereof) is determined based on those data, and the coupling weights can be analytically calculated by using the table. Where the number of times of change of the teacher data is odd, some inputs do not route a second hidden layer.

    摘要： In a recognition/diagnosis method, a relation between total sums of inputs of respective cases and teacher data is listed in the order of magnitude of the total sums of inputs. Based on the value of the teacher data for the input having the maximum total sum and the number of times of change of teacher data in the table are considered, a configuration of a neural network (the number of hidden layers and the number of neurons thereof) is determined. Coupling weights are analytically calculated based on the table.

    摘要： A bushing has a central conductor, and a plurality of internal shield rings. Gaps are formed between the shield rings such that equipotential lines extend through gaps. Electric field concentration in a tangential distribution on a part of the surface of the bushing corresponding to an upper part of an internal shield ring is relieved to prevent corona discharge under wet conditions, and antipollution performance and withstand voltage characteristics can be improved.

    摘要： An insulated device diagnosing system is capable of judging the deterioration, lifetime, and defects of a device. The intensity at each voltage phase angle is measured at a plurality of specific frequencies, taking high voltage phase angles as the abscissas. The deterioration, lifetime, and the kind and extent of abnormality of the device are judged from the pattern and intensity of the spectral distribution, which is obtained by peak-holding the measured intensity for a defined time period. According to the present invention, partial discharge can be measured highly sensitively and precisely to diagnose the deterioration, lifetime and the extent of defect of the device. As a result, the insulation reliability of the device can be improved, and the part of the device that should be repaired/replaced can be grasped before disassembly of the device, thereby cutting the maintenance cost.

    摘要： In a gas insulated electric apparatus having gas sections filled with insulating gas, a locating device determines a position of a gas section in which an insulation abnormality is detected, on the basis of a detection signal from sensors disposed in each of predetermined gas sections. At the same time a hindering degree diagnosing device diagnoses the degree and the kind of the insulation abnormality, by comparing a detection signal from the sensors with data stored in a data base. A valve control generates a valve control signal, responding to the locating device and the hindering degree diagnosing device, and in response to the valve control signal, a trip circuit generates a valve opening signal to open an electromagnetic valve disposed in a gas section in which an insulation abnormality is detected. An insulating gas injecting and evacuating device injects an insulating gas, different from the initial insulating gas with which the gas sections are filled beforehand, into the gas section for which the electromagnetic valve has been opened by the valve opening signal, or evacuates a predetermined amount of the insulating gas with which the gas sections are filled beforehand, so as to increase insulation strength.
