摘要： A three-phase collected type optical current transformer having a common hermetically sealed container (1) miniaturized in its radial direction. The common hermetically sealed container incorporating central conductors (2A, 2B, 2C) and optical current transformers (3A, 3B, 3C) corresponding to three phases has a branch tube or flange (1a) in its radial direction. The flange incorporates optical spacial transmission members (6A, 6B, 6C) for three phases which guide the signals sent from the optical current transformers (3A, 3B, 3C) through optical fibers (5A, 5B, 5C) to the exterior of the common hermetically container. The optical spacial transmission members are arranged collectively. The common hermetically sealed container, when it has a branching portion (1b) protruding in its radial direction at its end, incorporates no flange but a concentrated optical spacial transmission member (6) for three phases at the end in the axial direction of the common hermetically sealed container having the branching member. Thus, the common hermetically sealed container can be simplified in its structure so as to be miniaturized in the radial direction.

摘要： A puffer type gas-insulated circuit breaker is adapted to, when its movable electrode (3) separates from a stationary electrode (4), let an insulating gas (10) blow to an occurring arc (A) to extinguish the same. As insulated nozzle (1) is provided to direct the gas (10) toward the arc (A) and forms a gas passage (16) in cooperation with an insulating cover (2) which covers the movable electrode (3). The insulated cover (2) is formed of an insulating material which contains a filler for preventing energy lines of the arc (A) from entering the cover (2). Furthermore, the insulated cover (2) has a specific inductive capacity larger than that of the insulated nozzle (1) so as to make small the electric field strength at the front end of the movable electrode (3).

摘要： In a gas insulated electric apparatus having a plurality of gas sections (3a - 3d) filled with insulating gas, locating device (17) orientates position of a gas section, in which insulation abnormalities are produced, on the basis of a detection signal from sensors (13a, 13b) disposed in each of predetermined gas sections and at the same time hindering degree diagnosing device (18) diagnoses the degree and the kind of the insulation abnormalities, while comparing a detection signal from the sensors with data stored in a data base (19). A valve control (20) generates a valve control signal, responding to the locating device and the hindering degree diagnosing device and trip circuit (2) generates a valve opening signal for opening an electromagnetic valve (9) disposed in a gas section, in which insulation abnormalities are produced, responding to this valve control signal. Insulating gas injecting and evacuating device injects an insulating gas different from the insulating gas, with which the gas sections are filled beforehand, in the gas section, for which the electromagnetic valve opened by the valve opening signal is disposed, or evacuates a predetermined amount of the insulating gas, with which the gas sections are filled beforehand, so as to increase insulation strength.

摘要： Disclosed is an insulating spacer (3) for use in a gas-insulated electric apparatus for supporting a high-tension electric conductor (2) inserted through a metallic pipe (1) enclosing an insulating gas, in which the insulating spacer (3) is provided with a plurality of fins (7c, 8c, 9c; 5, 6; 7a, 8a, 9a; 7b, 8b, 9b, 10b, 11b; 10, 11, 12, 15, 16, 17, 18; 19, 20, 21, 22, 23) on its creeping surface, and in which fin intervals (dc₁, dc₂, dc₃, dc₄; d; da₁, da₂, da₃, da₄; db₁, db₂, db₃, db₄, db₅, db₆; d7, d8, d9, d13, d14, d15, d16; d19, d20, d21, d22) between the metallic pipe and one of the fins adjacent to the metallic pipe, between adjacent ones of the fins, and between the high-tension electric conductor and one of the fins adjacent to the high-­tension electric conductor are formed in a manner so that the fin interval (dc₁, d₉, d₁₃, d₁₆, d₁₉) formed at a position is made narrower than the fin interval (dc₄, d₇, d₁₄, d₁₅, d₂₂) formed at a position where a creeping component electric filed is lower than that in the first-­mentioned position. Thus, the dielectric strength improvement rate becomes larger at a position where the creeping component electric field is higher so that substantially even creeping dielectric strength can be obtained even when an electrically conductive foreign matter adheres wherever on the outside of the insulating spacer.
