We know that the box transformer is abbreviated as box change; while the underground transformer is simply referred to as underground change.
The so-called underground transformer is a type of box substation. It can be said that this is a set of power supply and distribution equipment that is very practical. Like all box change equipment, they are prefabricated and assembled in a factory and installed on-site at the project.
Underground transformer structure
Taking the "semi-underground transformer" as an example. Each underground transformer is divided into two parts: above ground and underground. The underground part is the transformer section, usually buried in a trench underground, which is rarely seen by the general public; while the above-ground part is an outdoor switch device in the form of an advertising light box, which can be seen in many places, often featuring mainstream advertisements. Therefore, some people also call them light box substations.
Thus, the underground transformer is a new type of compact substation equipment composed of transformer, high-voltage load fuse switch, fuses, and other unit devices. Its main body is installed in a pit, occupying little surface space.
Advantages of underground transformers
Higher protection level
Since a large part operates underground, it requires a high protection level, reaching IP68. Transformers designed with strict standards and high specifications can operate for a period of time even when submerged in water. Stronger environmental adaptability.
Under conditions of altitude not exceeding 1000m, it can work normally in environments ranging from -30 to 40 degrees.
Landscape characteristics
The internal box of the above-ground part contains high and low voltage distribution cabinets, with advertising light boxes on both sides. When powered on, it has an excellent visual effect, which can be said to achieve two goals at once.
In summary, it can be seen that this is an energy-saving, environmentally friendly, more efficient, and safer box substation.
