At this time, when the cabinet combination operation of the first high-voltage switch cabinet and the second high-voltage switch cabinet needs to be realized, firstly, one end of the conductive conical head 4 is connected with the bus of the first high-voltage switch cabinet, then, the bus of the second high-voltage switch cabinet is connected with the vacant end of the second conductive guide 71, the first high-voltage switch cabinet and the second high-voltage switch cabinet move in opposite directions, and the reliable connection between the first high-voltage switch cabinet and the second high-voltage switch cabinet can be realized through the guide splicing matching between the conductive conical head 4 and the second groove 71a on the second conductive guide 71. And as shown in fig. 6, the cabinet group after cabinet combination also has the advantage of small volume.
Since the design concept of the cabinet combining device in this embodiment 2 is the same as that of the cabinet combining device in embodiment 1, which has two conductive conical heads 4, two insulating conical pipes 5 and a guiding conical head 6 with a groove 61a formed in both directions, other corresponding structural designs of the cabinet combining device in embodiment 1 are also applicable to the cabinet combining device described in this embodiment 2.
