Claims (1)

[Scope of Claim for Utility Model Registration] (1) A cubicle in which necessary equipment including a power receiving side disconnector and a circuit breaker are housed in a cubicle container filled with insulating gas, and a cable head is attached near the power receiving side disconnector. type power receiving equipment, wherein a lightning arrester is housed in the lightning arrester element container to form a lightning arrester element, a hand hole is provided in a wall portion of the cubicle container at a location where the power receiving side disconnector is desired, and the lightning arrester is inserted into the hand hole. Both the element and the hand hole closing cover plate can be connected, and the power receiving side disconnector has a fixed electrode electrically connected to a main circuit connected to the circuit breaker, and a rotating switch that is operated to rotate. A movable electrode that is connected to a conductor and moves toward and away from the fixed electrode, and a power-receiving sliding contact that is connected to the cable head and is constantly in contact with the rotating conductor, and is located at a position facing the hand hole. The rotational axis of the rotating conductor is arranged in a direction perpendicular to the central axis of the handhole, and the lightning arrester element contacts the rotating conductor when connected to the handhole and connects the terminal of the lightning arrester. A sliding contact electrically connected to the rotating conductor is provided, and when a hand hole closing cover plate is attached to the hand hole, a predetermined insulation distance is ensured between the disconnector and the cover plate. A cubicle type power receiving equipment characterized in that the position of the disconnector is set so as to (2) The hand hole is provided so that the lightning arrester elements can be connected in different orientations of 180 degrees along the vertical direction, and when the lightning arrester elements are connected in either orientation, the lightning arrester side sliding contact can be connected. Claim 1, wherein the position of the rotating conductor of the disconnector and the position of the sliding contact on the lightning arrester side are set so that the rotating conductor can be brought into contact with the rotating conductor.
