The above scheme can be used to facilitate maintenance. It can be understood that the above scheme can facilitate maintenance of the busbar duct body 102.

[0021] In this embodiment, the bus duct body 102 is disposed in the box body 101 , and a terminal post is disposed on the top of the bus duct body 102 .

[0022] The guide rail 103 is fixedly connected to the box 101 and is located on both sides of the bottom of the box 101. The mounting plate 104 is fixedly connected to the guide rail 103 and is fixedly connected to the bus duct body 102 and is located on the guide rail 103. The sealing plate 105 is arranged on the front side of the box 101. The plug-in assembly is arranged on the side of the mounting plate 104 close to the sealing plate 105. The limit assembly is arranged on the side of the box 101 close to the guide rail 103. The guide rail 103 is installed on the box 101 by bolts, and the linear slider equipped therewith is connected to the mounting plate 104 by bolts. The bus duct body 102 is fixed to the mounting plate 104 by bolts. The sealing plate 105 cooperates with the mounting plate 104 through the plug-in assembly to achieve installation. The limit assembly is arranged on the side of the box 101 close to the guide rail 103 for pulling the limit.

[0023] Secondly, the stabilizing rail 106 is fixedly connected to the box 101 and the mounting plate 104, and is located between the guide rails 103. The stabilizing rail 106 is mounted on the box 101 by bolts, and the linear slider equipped therewith is mounted on the mounting plate 104 by bolts.
