Its main functions include centralized cable laying to enhance the heat dissipation effect of the cables and improve the transmission efficiency of the cables; protecting the cables to prevent them from being damaged or failing due to external factors; and beautifying the environment and improving the overall aesthetics of the garden landscape. The wind farm is backed by the mountain. When the rainfall is heavy (especially in the rainy season and typhoon weather), the water accumulation height of the cable trench can be about 80-90cm. If the cable trench is immersed in water for a long time, the risk of cable insulation aging will increase. After the cable insulation ages, the technical performance of the cable will be affected, and it is easy to have faults such as short circuit and power failure. The power equipment is in a humid environment for a long time, which will cause the equipment to be damp, condense, corrode, etc., which will damage the normal operation of the equipment. However, the device also has the following defects: due to the water seepage at the bottom of the indoor cable trench in the equipment room of the main control building of the wind farm, the cable trench is flooded for a long time, and the high-voltage cables, moving cables, control cables and other cables in the cable trench are also immersed in water for a long time, which has hidden dangers affecting the safe operation of the equipment.
