Abstract: A bus container, its assembling method and a gas-insulated switchgear, in which gas treating working in a factory and at a site is reduced, an operation is made simple, and a process is shortened. In the case of connection of a container (101) and a container (102), a conductor (103) of spherical shape is kept in contact with and fixed to a contact (102f), the container (101) is caused to approach to the container (102), the conductor (103) is joined to a contact (101f).

Abstract: In order to realize reduction of a gas insulated switchgear, a connection bus for connecting potential current transformer units, a first connecting unit, power receiving units and transformer connecting units or for connecting the potential current transformer unit, a bypass unit, a first connecting unit, the power receiving units and transformer connecting units is arranged horizontally to a connecting unit and in parallel thereto. Thereby height dimensions of the transformer connecting units, potential current transformer units and transformer connecting units can be made small and thus a height dimension of the entire apparatus can be made small.

Abstract: A power receiving unit is arranged in one side of an instrument potential/current unit transformer. A transformer-side unit is arranged in the other side of the instrument potential/current transformer units. A bypass bus connecting the power receiving unit and the transformer-side unit is arranged in parallel to the row of cubicles. The gas insulated switchgear can be made small in size and the work for adding a bank can be performed with substantially small man-power. The size of the gas insulated switchgear can be also prevented from increasing due to the addition of a bank.

Abstract: The present invention provides a compressed gas insulation switchgear requiring a comparatively small area for installation and facilitating installation of additional banks. According to one embodiment of the invention, potential current transformer units are disposed in the central area, power receiving units are disposed on the outer side of the potential current transformer units, transformer side units are disposed on the outer side of the power receiving units, and buses interconnecting the units are extended in parallel to a row of cubicles on an upper level and a lower level.

Abstract: A high voltage power receiving and transforming apparatus for consumer demands receiving power from two lines and supplying the power to respective transformers through instrument potential and current transformers. First circuit breakers at a primary side of the transformers, are arranged at both sides of the instrument potential and current transformers, second circuit breakers, at a receiving side, are arranged at both sides of said first circuit breakers. The circuit breakers and receiving portion connecting portion to the transformers, and the instrument potential and current transformer are connected by a duct line connection portion at a backside of the circuit breakers.

Abstract: A power receiving and transforming system comprising a gas insulated switchgear, with transformers being disposed adjacent the gas insulated switchgear and metal enclosed switchgear sections disposed on opposite sides of the transformers with respect to the gas insulated switchgear. The metal enclosed switchgear sections have metal enclosed switchgear units juxtaposed in a direction in which the gas insulated switchgear and the transformers are juxtaposed. The metal enclosed sections are located opposite to each other in a direction perpendicular to the direction of the juxtaposition. Therefore, the metal enclosed switchgear sections can be arranged so as to have a width equal to a width of the gas insulated switchgear and the width will not change even if the number of feeders in the metal enclosed switchgear sections is increased thereby enabling the entire power receiving and transforming system to be regularly installed at a site.
