Box Type Substation

Box-type substation is a kind of power equipment integrating traditional transformers and related equipment. It is a completely sealed toughened box structure with transformers, high-voltage voltage control equipment, low-voltage voltage control equipment and so on. A box-type transformer is a closed transformer and usually composed of an iron core, winding and housing. Its shell is made of insulating material or metal material and contains input windings and output windings. It realizes voltage transformation through electromagnetic induction law. Box-type transformers are usually equipped with cooling equipment such as radiators or fans to ensure stable operation in a variety of environments‌.

1. Compact structure
The box-type substation adopts a modular design. It puts all the key equipment in a metal box, which can reduce the floor space. Compared with traditional substations, the box-type substation is smaller and more suitable for installation in areas without space. This makes the box-type substation a suitable power equipment for urban life, industrial parks, high-rise buildings and other places, effectively saving land resources.
2. Safe and reliable
The shell of the box-type substation is made of steel plate or other solid materials, which can well protect and resist external impact. The closed design can ensure the cloud-top operation of the internal equipment and resist the disturbance of bad weather and special environment. In addition, the sealed box and protective performance can protect the equipment from the influence of moisture factors, greatly improving the service life of the equipment.
3. Convenient transportation and installation
Because the box-type substation adopts a prefabricated design, all equipment is assembled in the factory and transported to the site, which can speed up the installation time and is suitable for projects with a short construction period and power supply. In large-scale construction or temporary places where electricity is urgently needed, the box-type substation performs outstandingly.
4.Automation control
The box-type substation is equipped with a modern automation control system, which can monitor and manage power equipment. The automation system feedbacks the operating status of the equipment, warns of faults, and improves the operating efficiency and reliability of the equipment, which ensures stable and continuous power supply.
5.Energy saving and environmental protection
The box-type substation uses efficient transformers and advanced technologies, which can effectively reduce power loss and reduce operating costs. At the same time, due to its closed design, the box-type substation effectively reduces noise pollution and has strict requirements for noise. Energy saving and environmental protection can meet the sustainable development of modern society.

Placement: The box-type substation should be placed at a higher place, not in a low-lying place, so as to prevent rainwater from entering the box and affecting the operation of the equipment.

Grounding and zeroing: The grounding and zeroing of the box-type substation share a grounding grid. The grounding grid is generally made by driving grounding piles at the four corners of the foundation and then connecting them as a whole. The box-type substation and the grounding grid must have two reliable connections.

Ventilation and heat dissipation: The box-type substation is mainly cooled by natural wind circulation. No debris can be piled around it, especially the transformer room door. The blinds and vents should be cleaned frequently to ensure that the equipment does not exceed the maximum allowable temperature.

Regular inspection and maintenance: The ring network switch, transformer, lightning arrester and other equipment in the high-voltage room should be inspected and maintained regularly to detect faults and deal with them in a timely manner. Conduct insulation preventive tests regularly to ensure the safe operation of the equipment.

Baoding Yuanchen Transformer Manufacturing Co., Ltd. (established in 1999) has more than 20 years of industry experience. The company is large in scale, with a plant area of ​​98,000 square meters and a building area of ​​26,800 square meters. It has strong technical strength and has the full chain capabilities from product research and development, manufacturing and processing to after-sales service. The main products cover six categories of nearly 100 specifications, including 35KV and below oil-immersed transformers, dry-type transformers, mobile box-type transformers, prepaid high-voltage metering boxes, high and low voltage switchgear and charging piles, with an annual production capacity of up to 5 million KVA. In October 2020, the company passed the three major international management system certifications of ISO 9001, ISO 14001 and ISO 45001. In addition, the company is a high-tech enterprise (recognized in 2016, reviewed and passed in 2019 and 2022) and a specialized and new small and medium-sized enterprise in 2022. Its oil-immersed transformers were selected into the recommended catalog of energy-saving technology and equipment of the Ministry of Industry and Information Technology in 2022.
