The line changing assembly is used to control the connection or disconnection between the plug and the wiring terminal. The first-order wiring terminal 6a and the second-order wiring terminal 6b are respectively located on the upper and lower sides of the transformer body 6. Both plugs are connected to external wires.

[0031] A carrying slot 3a with a square track is provided on the carrying frame 3, and a square column 8 is slidably matched with the carrying slot 3a. Four voltage transformers are provided.

[0032] The transport assembly also includes a motor 4 installed in the center area of ​​the transport frame 3, the motor 4 is connected to a cross 5, and the cross 5 is evenly distributed with configuration slots 5a along the annular direction, and the square columns 8 pass through the corresponding configuration slots 5a respectively. That is, there are also four configuration slots 5a, and by driving the cross 5 to rotate, the four voltage transformers can slide along the square track of the transport slot 3a.

[0033] The locking assembly also includes a stand 9 installed at the rear of the outdoor platform 1 and a hydraulic cylinder 10 and an auxiliary slide bar 11 both installed on the stand 9; a row seat 12 connected to the hydraulic cylinder 10 is slidably installed on the auxiliary slide bar 11, and a U-shaped column 13 is installed on the row seat 12.

[0034] Each U-shaped plug post 13 is provided with a socket, and there are two U-shaped plug posts 13, and each voltage transformer has two pairs of extension rods 7. Under the push and pull action of the hydraulic cylinder 10, the sockets of the two U-shaped plug posts 13 are matched with the two pairs of extension rods 7 of the voltage transformer, so that the position of the voltage transformer can be fixed.

[0035] The line changing assembly also includes a high hanging seat 14 fixedly mounted on the right part of the outdoor high platform 1, and a three-axis cylinder 15, an A guide rail 17, and a B guide rail 20 all mounted on the high hanging seat 14; the three-axis cylinder 15 is connected to a tilting frame 16, and a tilting groove 16a is opened on the tilting frame 16.
