Dry type transformer

In the field of power grid transmission: mainly used in the terminal distribution of the power grid, as the core equipment of the medium and low voltage distribution network, it realizes the final voltage reduction adaptation. For example, in the regional distribution center, the 10kV medium voltage electricity transmitted by the power grid is converted into 380V/220V low voltage electricity, which is directly supplied to surrounding residents, commercial facilities, and small industrial users without the need for long-distance high voltage transmission. It is suitable for indoor installation needs of urban distribution terminals, while avoiding fire hazards of oil immersed equipment and ensuring the safety and stability of power supply to the power grid terminals.

Industrial production field: widely used in factories and industrial parks with high requirements for fire prevention and environmental protection, especially in precision manufacturing, electronics, pharmaceuticals and other industries. For example, in electronic component manufacturing plants, precision production equipment and testing instruments in the workshop have extremely high requirements for voltage stability and power supply safety. Dry type transformers convert 10kV high-voltage electrical energy input from the power grid into low-voltage electrical energy required by the equipment, with no oil pollution and low noise. They can be directly installed in the distribution room near the workshop to avoid affecting the production environment and precision equipment operation due to oil leakage, noise and other problems, ensuring the continuity of the production process.

In the field of urban and residential power distribution: it is mainly applied in densely populated indoor scenes with high fire prevention requirements, such as urban office buildings, commercial complexes, residential communities, hospitals, schools, etc. For example, in large office buildings, the electrical equipment such as office equipment, central air conditioning, lighting, elevators, etc. in the office building have a large and concentrated load. Dry type transformers are installed in the underground distribution room of the office building to reduce 10kV high-voltage electricity to 380V three-phase electricity and 220V single-phase electricity, supplying power to various devices. Its oil-free, fireproof and explosion-proof characteristics can effectively ensure the safety of personnel and property in the office building, and meet the environmental protection requirements of indoor enclosed distribution environment.

In the field of new energy grid connection: adapting to the electricity conversion and distribution needs of small and medium-sized photovoltaic, wind power projects, and new energy storage systems. For example, in rooftop photovoltaic projects, the direct current generated by photovoltaic modules is converted into 400V low-voltage alternating current by inverters, and then stepped up to 10kV through dry-type transformers before being connected to the regional distribution network. With its compact size and convenient installation, it can adapt to the limited installation space on rooftops without oil pollution, which is in line with the environmental protection concept of new energy projects and solves the grid connected distribution needs of small and medium-sized new energy power generation.

In the field of municipal and infrastructure: applied to municipal facilities such as urban rail transit, data centers, sewage treatment plants, etc. that require high power supply safety and environmental protection. For example, in a data center, core equipment such as servers and switches require 24-hour stable power supply, and the data center room is a closed space with extremely high fire prevention requirements. Dry type transformers provide stable low-voltage distribution support for the room, and intelligent temperature control functions can adapt to load fluctuations in the room. Oil free design avoids fire hazards and ensures the safe and continuous operation of core equipment in the data center; In the indoor computer room of the sewage treatment plant, power is supplied to equipment such as water pumps and control systems, and the environmentally friendly and pollution-free characteristics can avoid affecting the sewage treatment process.
