[0012] The above technical solution enables the busbar trunking to have good corrosion resistance.

[0013] The present invention is further configured such that the fireproof layer is a silane acrylate and the insulating layer is a polyurethane insulating varnish.

[0014] The above technical solution enables the busbar trunking to have good fire resistance and insulation.

[0015] The present invention is further configured such that the fixing mechanism includes a positioning rod fixed to the inner wall of the protective shell, a connecting block slidably connected to the outer side of the positioning rod, two connecting blocks, a spring fixedly connected to one side of the connecting block, a connecting rod fixedly connected to the top of the connecting block, a fixing block fixedly connected to one side of the connecting rod, a through groove opened in the inner wall of the cover plate, and a fixing groove opened in the inner wall of the through groove.

[0016] The above technical solution facilitates quick assembly and disassembly of the cover plate.

[0017] The present invention is further configured such that a lever is fixedly connected to one side of the connecting block.

[0018] The above technical solution facilitates the movement of the connecting block.

[0019] The present invention is further configured such that the fixing block is engaged with the fixing groove.

[0020] The above technical solution facilitates the fixing of the cover plate to the protective shell.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The protective mechanism provides convenient protection for the busbar trunking, while also offering waterproof, corrosion-resistant, fireproof, and insulation properties. This not only prevents rainwater from affecting the busbar trunking but also avoids electric shock to personnel during maintenance of the busbar trunking itself.

[0023] 2: The fixing mechanism allows for quick and easy disassembly and assembly of the cover plate and protective shell without the need for any workpieces, making it convenient and fast. Attached Figure Description
