摘要： An insulation gas filled circuit breaker in which a circuit breaking portion including two separably opposing contacts and a capacitor connected in parallel between the two contacts in the circuit breaking portion are disposed in a closed metal container filled with gas having an insulating property. A shield is provided at both the side of the capacitor facing the circuit breaking portion and the side of the capacitor facing the closed metal container for relaxing the electric field concentration near the capacitor. The top end of the shield is positioned so as to extend from the contacting face between the capacitor and an electrode pressing the capacitor toward the capacitor by a predetermined distance, whereby the dielectric strength of the capacitor connected in parallel with the circuit breaking portion is increased and a highly reliable and compact insulation gas filled circuit breaker of a high voltage and a large capacity use is provided.

摘要： The gas circuit breaker comprises a metal container filled with an insulating gas; first and second contacts disposed opposite each other in the metal container so that they can be brought into and out of engagement with each other; and a metal shield arranged in the metal container to enclose the two contacts. A part or a whole of the surface of the shield is oxidized and covered with a fluororesin layer. The gas circuit breaker with this construction can protect the shield surface against flaking and scores when subjected to mechanical impacts and can maintain high dielectric strength without increasing the size of the circuit breaker.

摘要： A method and apparatus for locating an abnormality in a gas-insulated electric device, operative to locate the spot of an insulation abnormality, which emerges inside a metallic container, from outside of said metallic container. A plurality of detectors (S.sub.0 -S.sub.n) disposed at certain positions in the metallic container produce detected signals, from which spectrum strengths (YH) in a high frequency band of 500 MHz or above are evaluated, and a position which renders a maximum spectrum strength is calculated from the relation between the spectrum strengths and the installation positions of the detectors and is determined to be the spot (x) of partial discharge.

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.
