摘要： In a gas-insulated switchgear apparatus, breakers of three phases are contained in a barrel-type sealed enclosure having an insulating gas sealed therein. At least one terminal of each of the breakers is connected to each of a plurality of main buses arranged on the outside of the sealed enclosure, and a common casing is attached to one side of the sealed enclosure to extend in the height direction thereof. The ground housing of each of the main buses is connected through an insulating spacer to the common casing. Connecting conductors for connecting the terminals of the breakers with the bus conductors of the main buses are led into the casing or a plurality of current transformers are arranged in the casing. By so doing, the sealed enclosure is reduced to a size having a sectional area sufficient for juxtaposition of the breakers of three phases and thus the whole gas-insulated switchgear apparatus is made more compact and smaller. Also, the connecting conductors and the current transformers are isolated from the breakers by arranging them inside the common casing and this has the effect of enhancing the insulation reliability and ensuring suitable arrangement of the current transformers.
摘要翻译： 在气体绝缘开关设备中，三相断路器包含在其中密封有绝缘气体的桶形密封外壳中。 每个断路器的至少一个端子连接到布置在密封外壳的外侧上的多个主母线中的每一个，并且公共壳体附接到密封外壳的一侧，以在其高度方向上延伸。 每个主母线的接地壳体通过绝缘垫片连接到公共壳体。 用于将断路器的端子与主母线的母线连接的连接导体被引导到壳体中，或者多个电流互感器被布置在壳体中。 通过这样做，密封的壳体被减小到具有足以使三相断路器并置的足够的截面积的尺寸，从而使整个气体绝缘开关装置更紧凑和更小。 此外，连接导体和电流互感器通过将其布置在公共壳体内而与断路器隔离，并且具有提高绝缘可靠性并确保电流互感器的适当布置的效果。

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 apparatus has a sealed container including a cylinder body having a substantially circular cross-section and end plates closing the end portions of the cylinder body. The sealed container accommodates breaker portions situated so as to work opening and closing actions in the vertical direction and current transformers. Main bus bars located on the side of the sealed container are connected with the breaker portions located inside of the sealed container through openings formed in the end plates. A line side terminal portion located on the side of the sealed container is connected with the breaker portions locating inside of the sealed container through openings formed in the end plates.
