摘要： A gas-insulated switchgear apparatus including a three-phase circuit breaker, a three-phase disconnecting switch and a cable head, with the disconnecting switch and the cable head being accommodated in a cable head housing. To minimize the size of the disconnecting switch, movable insulators, connected to movable conductors, and stationary insulators, supporting connecting conductors, are arranged so that the movable and stationary insulators form triangles disposed substantially in the same plane with the respective triangles being inverted in relation to each other.

摘要： A gas-blast load-break switch comprises a pressure storage chamber for storing pressure of arc-extinguishing gas with arc energy generated by the disconnection between contacts, and a suction chamber including a piston which is moved in connection with the cut-off movement of the movable contact. A gas flowing device is provided such that the pressure raised by the arc energy is stored in the pressure storage chamber before communicating the pressure storage chamber and the suction chamber and a gas chamber formed on the opposite side of the piston from the suction chamber. The volume of the gas chamber is greater than that of the pressure storage chamber and the suction chamber, and the distance of piston movement in the suction chamber is longer than the contact length when the movable contact is thrown into the fixed contact.

摘要： A gas insulated switchgear equipment in which three circuit breakers are electrically connected in series between two main bus bars. The two main buses are parallelly mounted on a fixing base. The three circuit breakers are arranged on one side of the main buses and aligned in the axial direction of the main buses. Connecting buses for electrically connecting the circuit breakers are provided on one side of the circuit breakers where the main bus bars are also disposed. Thus, the circuit breakers are accessible from the other side thereof for their maintenance and inspection and the equipment mounting area can be minimized because the main buses are disposed in parallel.
摘要翻译：一种气体绝缘开关设备，其中三个断路器串联在两个主母线之间。两条主母线平行安装在固定座上。三个断路器布置在主母线的一侧，并沿主母线的轴向对齐。连接断路器的连接母线设置在断路器的一侧，主母线也设置在断路器的一侧。因此，断路器可从其另一侧进入以进行维护和检查，并且由于主母线平行设置，所以能够最小化设备安装面积。

摘要： Gas-insulated switchgear equipment includes a plurality of vertical-type circuit breakers electrically connected in series, and outside led-out devices connected to connected portions of a series connection of the circuit breakers and at least one main bus bar connected to two of the plurality of circuit breakers located at both ends of the series connection. In the equipment, the circuit breakers are a vertical type circuit breaker and are arranged on a substantial straight line and led-out portions for leading out terminals formed in the circuit breakers in a direction perpendicular to a direction of the arrangement of the circuit breakers, and connecting bus bars interconnecting the circuit breakers in series and the outside led-out devices are disposed on one side of the circuit breakers and the at least one main bus bar is disposed on the other side of the circuit breakers. Therefore, the fixing area can be reduced and the connection between the at least one main bus bar and the circuit breakers and between the circuit breakers and the outside led-out devices can be easily established.
