Description

Technical Field

[0001] The invention relates to the technical field of ventilation cover plates, in particular to a ventilation cover plate for a cable trench of a transformer substation. Background Art

[0002] The use of power cables can not only effectively reduce the workload of operation and maintenance, but also greatly improve the reliability of power supply and ensure the safety of power grid operation. At present, substations widely use the cable trench laying method, which has the advantages of simple building structure, few additional supporting facilities such as technical defense, low project investment, and high economy.

[0003] Traditional ventilation covers for cable trenches in substations are mainly composed of covers, protective nets, bases, etc. The covers are used to cover the openings of the cable trenches to prevent debris and people from falling in. The covers are usually made of strong and durable materials, such as steel fiber concrete, etc. The protective nets are usually set under the covers to prevent large foreign objects from falling into the cable trenches while ensuring ventilation. The mesh width and spacing of the protective nets will be designed according to actual needs to ensure that they can effectively block foreign objects and ensure good ventilation.

[0004] Existing substation cable trench covers are mostly cast in cement, so they are heavy and difficult to open. They require two workers to work together with a crowbar or iron hook to open them, which is time-consuming and labor-intensive. In addition, due to waterproof performance considerations, substation cable trench covers are mostly solid and non-porous, which reduces the ventilation performance in the cable trench, resulting in the inability to discharge the heat emitted by the cables inside the cable trench, causing heat accumulation inside the trench, posing a serious safety hazard. Summary of the invention
