Description

Technical Field

[0001] The utility model relates to the technical field of substations, and in particular to a buried substation. Background Art

[0002] A buried substation refers to a substation whose complete set of devices are all installed inside a fully sealed box. The box-type substation device is relatively large in volume and requires a certain amount of space. In areas with tight land use or harsh environments such as parks, residential areas, and industrial areas, a substation device that is entirely set below the ground plane is formed into a buried substation, enabling the ground above the substation to be utilized, effectively saving ground space and improving land utilization rate. At the same time, there is no need to perform aesthetic design on the outer shell of the substation, and the possibility of damage to the buried substation is small, which can improve the safety of power use. During the use of the buried substation, since the device is installed inside the box, a large amount of heat will be generated during operation. Therefore, the demand for ventilation and cooling inside the buried substation can be increased, and regular maintenance and repair of the interior are also required. Based on this, we propose a buried substation. Content of the Utility Model
