摘要： PROBLEM TO BE SOLVED: To achieve the standardization and the common use of T-branched bus and to make it possible to achieve the cross-shaped branching, by arranging three-phase conductors straight and in parallel in side a grounding metal container. SOLUTION: A bus container (grounding metal container) 1 and a T-branched container 4 are connected. An insulating spacer 8 is provided at a flange 21, which is attached to the end part of the T-branched container 4. A breaker is connected through a tulip-shaped contact 9 arranged at the outside. Then, three-phase conductors 2 are arranged in parallel in the straight-line pattern in the longitudinal direction. In the T-branched container 4, the connecting lines T-branched from the conductors 2 are arranged in the T-branched container 4. Blades 3 are provide at the halfway of the connecting lines. At this time, the three-phase blades 3 are aligned in the plane vertical to the plane wherein the three-phase conductors 2 are aligned. Thus, the common use and the standardization of the arrangement of the buses can be achieved, and the cross-shape bus branching can be performed.

摘要： PROBLEM TO BE SOLVED: To obtain a receiving and transforming apparatus whose specifications can be made common to those of a receiving and transforming system by a method wherein a bus which connects a receiving and transforming unit to the primary side of a transformer-current transformer unit for measurement and a bus which connects the secondary side of the transformer-current transformer unit for measurement via a disconnecting switch are housed in one container. SOLUTION: A bus 50 is connected via a disconnecting switch 9 installed on the secondary side of a breaker 8 at a receiving unit, and it is connected to a PCT bus 51 at a PCT unit. A transformer-current transformer 11 for measurement is arranged on the lower side at the PCT unit, and it is T-branched so as to be connected to the PCT bus 51. A first-half conductor bus 51 from the disconnecting switch 9, a return conductor up to a disconnecting switch 12 from the PCT bus is arranged coaxially, a back-and-forth conductor structure is adopted, and the conductors are housed in one container.

摘要： PURPOSE: To hinder the action from shifting from the changeover of action being one object of operation to the changeover of action being the other object of operation, when a manual operation handle is kept mounted on a manual operation shaft. CONSTITUTION: The on/off operation of a breaker or the off/earth operation of an earthing device is performed accompanying the rotation of an output shaft 24. An output shaft lever 26 is coupled with this output shaft 24, and a projection 28 is made at the lever 26. When an operation part 34 is in the first retaining hole 48, the on/off operation of the breaker is possible, and when the operation part 34 is in a second retaining hole 50, the off/earth operation of the earthing device is possible, and the changeover of the operation from the breaker to the earthing device or from the earthing device to the breaker is possible only when the slide plate 39 is slid in the direction A. when the manual operation handle 12 is mounted on the manual operation shaft 10, even if the slide plate 39 seeks to shift in the direction A, it abuts on the manual operation handle 12, and the shifting is checked.
