[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

[0018] As Figure 1 , Figure 2 and Figure 3As shown, the present invention proposes a protective structure for the connection cable of DCS equipment in a thermal power plant, including a fixed plate 1, a distributed wiring structure 2, and a heat dissipation structure 3. The distributed wiring structure 2 is disposed on the fixed plate 1, and the heat dissipation structure 3 is disposed on the fixed plate 1. The distributed wiring structure 2 includes a centralized control box 4, a main controller connector 5, a distributed control connector 6, a wiring board 7, and a distributed cable tray 8. The centralized control box 4 is fixedly disposed on the fixed plate 1, the main controller connector 5 is fixedly disposed inside the centralized control box 4, the distributed control connector 6 is fixedly disposed on the fixed plate 1, and the distributed control connector 6 is provided with multiple groups for zone control of different systems. The wiring board 7 is fixedly disposed on the fixed plate 1, and the distributed cable tray 8 is recessed on the wiring board 7. The wiring board 7 is arranged in multiple folds and distributed vertically, and the distributed cable tray 8 is arranged in sections on the top of the wiring board 7.
