摘要： The present invention is provided to satisfy insulation and conductivity performance requirements, to reduce the size of a gas insulated bus, and also to make conditioning for a particle more reliable. In a gas insulated bus having a conductor supported in a cylindrical metal container via an insulator, insulating gas being contained in the metal container, the metal container has an expanded diameter part formed over a given range in an area of the metal container in which the insulator is positioned and a reduced diameter part formed over the entire area of the metal container except for the expanded diameter part. Thus, when the temperature of the insulator increases during conduction, heat from the insulator is transferred to the metal container via a large space in the expanded diameter part and released to the air through a large outer surface of the expanded diameter part of the metal container.

摘要： In the measurement of partial discharge, a voltage detected by the antenna is input into a spectrum analyzer and a phase difference between an operating voltage and a power supply of the spectrum analyzer is obtained by phase domain analysis using the spectrum analyzer. Based on the phase difference and the voltage phase shift associated with input impedance of the signal converter circuit, the time axis displayed on the screen of the spectrum analyzer is compensated. After the compensation has been carried out, the voltage detected by the antenna is input into the spectrum analyzer, the partial discharge pattern which synchronizes with the operating voltage is measured by phase domain analysis using the spectrum analyzer.

摘要： A gas insulated device includes a grounded tank filled with an insulating gas and having a conical insulator spacer securely mounted therein to define an interior space. A through-type electric connector extends through and is supported by the insulated spacer and an electric conductor is electrically connected to the through-type electric conductor by a conductor connector. The conductor connector closest to the insulator spacer is positioned such that electric flux lines exiting from the conductor connector intersect with the surface of the insulator spacer in a region in which an electric field has a strength equal to or less than 70% of the strength of the strongest electric field on the surface of the insulator spacer generated by a lightning impulse applied to the gas insulated device.

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.
