Product structure characteristics and configuration
Product features:  
1. The landscape-type buried box substation adopts a modular design as a whole, which not only occupies a small area, but also has a high waterproof function.
2. The low-voltage power distribution cabinet above the ground is mainly made of stainless steel, which can realize the adjustment of high and low voltage according to the user's electricity demand.
3. For the sake of beautiful appearance, a full-color LED display screen is used in the design process of the landscape light box. The display screen can display rich and varied color patterns and animation videos, and can also show some real-time dynamics in society for residents to understand. , to display the multimedia effect perfectly.
4. The intelligent landscape-type box-type transformer can not only meet the needs of residents to achieve high and low voltage equipment, but also realize the remote measurement function of voltage, current and other information by configuring DTU intelligent monitoring devices.
5. Compared with the traditional box substation, the landscape buried box substation also adopts a fully sealed design, which has high waterproof performance.
6. In order to ensure the normal operation of the transformer and reduce the impact of the environment, an automatic drainage and temperature detection system is installed in the buried transformer and placed in a fully sealed box.
7. The installation of the landscape-type buried box transformer is relatively simple. It is only necessary to place the transformer in the pre-set pit, then tamp the soil and install the box on the ground. Generally, it is not necessary to separately install the buried transformer. maintain.  
Product configuration:
The landscape type transformer box includes buried transformers. The iron core of the buried transformer is mainly S11 series solid rolled iron core. Compared with the amorphous alloy iron core transformer of SH15, the loss of the transformer is lower, which has the characteristics of material saving and energy saving. Especially when the transformer is no-load, the loss and no-load current are lower. As the lighting system in the city is often in the no-load state, S11 series of three-dimensional coil core transformers are more in line with the needs of urban lighting system construction. At the same time, the buried transformers of this series also have good sealing and waterproof functions and insulation and anti-corrosion functions.
The high-voltage part is mainly configured with SF6 switchgear, which is not only small in size, but also generally does not require maintenance, and has safe and reliable use performance.
The configuration of the low-voltage part is mainly the setting of the low-voltage distribution cabinet. The energy-saving device is installed in the low-voltage distribution cabinet, and the street lamp remote monitoring system and power supply metering system are installed on the side to achieve the telemetry function. At the same time, in order to achieve the beautiful appearance, the design of the outer light box is more flexible.



Product Advantages and Conditions of Use
Product Advantages:
1. The landscape-type buried substation can be called in many ways, such as semi-buried box-type substation, landscape-type box-type substation, pre-installed underground box-type substation, landscape-type buried substation, etc. This is a low-carbon, energy-saving, environmentally friendly, and green integrated power distribution equipment. Their application in many fields is more in line with our concept of building an "energy-saving society", and it is more energy-saving and environmentally friendly, beautifying the environment, and reliable operation. Many advantages.
2. The landscape buried box substation is a box substation product born for the needs of urban development. It is a complete set of power supply and distribution equipment that is further developed and improved on the basis of the traditional box substation technology. The underground part of the landscape buried box substation It occupies less than 6m², and the ground part occupies less than 3m².
3. Landscape-type box-type transformers are very suitable for installation in green belts such as gardens. Traditional box-type transformers must occupy an area of at least 10-20 square meters, and the power distribution room may occupy 70-100 square meters. In real estate development projects, such an occupation The proportion of the land area is very large. If the landscape buried box substation is adopted, the land occupation and civil construction costs can be reduced, and the taste of the community can be improved.
4. Especially in high-end residential areas, it is usually necessary to reserve a large piece of land for the construction of power distribution rooms or the installation of European and American substations, which invisibly takes up a huge amount of assets of the developer, and cannot solve the various concerns of the surrounding residents. The traditional The transformer is installed above the ground, which is very noisy and has poor aesthetics.
