摘要： There is provided a gas circuit breaker that can appropriately ensure a pressure and a density of arc-extinguishing gas to be sprayed to an arc, and can more surely maintain electric insulation performance. A gas circuit breaker 1 includes a first arc contactor 21 electrically connected to a first lead-out conductor 7a, a cylindrical guide portion 41 provided on a second lead-out conductor 7b side, a trigger electrode 31 which is arranged to be movable between the first arc contactor 21 and the guide portion 41, and which ignites an arc generated between the first arc contactor 21 and the trigger electrode along with a movement in a first half of a current breaking action, a compression chamber 36 for pressurizing arc-extinguishing gas, the compression chamber being formed by a cylinder 42 which has an outer wall 51 and an inner wall 52 both formed in a cylindrical shape, and which is provided on the guide portion 41 side, and a piston 33 that slides between the outer wall 51 and the inner wall 52 in conjunction with the trigger electrode 31, and an insulation nozzle 23 which guides the arc-extinguishing gas pressurized in the compression chamber 36 to an arc ignited at the first arc contactor 21. The insulation nozzle 23 is formed integrally with the inner wall 52 of the cylinder 42.

摘要： Provided is a gas circuit breaker such that degradation in insulation performance and current breaking performance due to unwanted gas generated from an arc-extinguishing gas sprayed on an arc can be reduced. The gas circuit breaker includes a sealed container 8 in which an arc-extinguishing gas is enclosed, a first fixed contact portion 2 fixed to the sealed container 8, a second fixed contact portion 4 fixed to the sealed container 8, and a movable contact portion 3 moving between the first fixed contact portion 2 and the second fixed contact portion 4 to conduct or block the current of the first fixed contact portion 2 and the second fixed contact portion 4, and extinguishes, by spraying the arc-extinguishing gas, an arc which is generated between a fixed arc contact 21 provided in the first fixed contact portion

摘要： A gas insulated switchgear and a gas insulated bus which improve an insulation performance and an insulation reliability are provided. The gas insulated switchgear has a supporter 3 supporting a high-voltage conductor 1 in a sealed container 2 filled with an insulation gas 4. An electric-field easing shield 5 that is an insulator is provided between the supporter 3 and the high-voltage conductor 1. A conductive layer 10 electrically connected to the high-voltage conductor 1 is formed on an opposing face of the electric-field easing shield 5 to the high-voltage conductor 1. Alternatively, an end shield 6 that is an insulator is provided between the electrical-line end of the high-voltage conductor 1 and the sealed container 2. The conductive layer 10 electrically connected to the high-voltage conductor 1 is formed on an opposing face of the end shield 6 to the electrical-line end.

摘要： According to an embodiment, a gas insulated electrical equipment includes: a high-voltage conductor (3) to be electrically charged; a hermetically sealed tank (12) to be filled with insulating gas (15), one or more insulating spacers (11) for dividing the hermetically sealed tank (12) into gas compartments and supporting the high-voltage conductor (3); and a pressure release device (2) equipped with a mouth of flow channel adapted to allow the inside and the outside of the hermetically sealed tank (12) to communicate with each other so as to release the pressure in the hermetically sealed tank (12), which maintains the hermetically sealed state in an ordinary condition where the pressure in a gas compartment (111) does not exceed the working pressure but releases the pressure in the hermetically sealed tank (12) in an abnormal condition where the pressure in the gas compartment (111) exceeds the working pressure.

摘要： A gas insulation apparatus(e.g., a gas circuit breaker) includes a high-voltage unit, a zeolite(20) and an insulation gas in a closed vessel(10). The insulation gas is CO 2 gas or a gas including CO 2 gas as the main component. The zeolite (20) is contained in a zeolite case(21) and is placed under an insulation gas atmosphere. CO 2 is adsorbed on the zeolite (20) before use of the gas insulation apparatus.
