The pad-mounted transformer is a device widely used in power transmission and distribution systems. It originated in the United States and has been widely used around the world after years of development. In China, with the acceleration of urbanization and the continuous growth of electricity demand, the pad-mounted transformer has gradually become an important equipment in the fields of urban distribution network transformation, new energy power generation, etc. with its advantages of high efficiency, environmental protection and reliability.

Composition and functions of pad-mounted transformers

Pad-mounted transformers are mainly composed of transformers, switches, protection devices, temperature control devices, distribution cabinets, etc. Its main function is to convert high-voltage electric energy into low-voltage electric energy and distribute it to various end users through transformers and distribution devices. Pad-mounted transformers are usually installed in public places such as substations, industrial parks, and urban streets to provide stable and reliable power supply for residents and commercial users.

Technical features of pad-mounted transformers

1. High integration

The pad-mounted transformer integrates high-voltage switchgear, transformer, and low-voltage power distribution equipment in one box, achieving a high degree of integration of the equipment. This design not only reduces the equipment footprint, but also reduces civil construction costs and improves the overall efficiency of the equipment.

2. High reliability

The pad-mounted transformer adopts a fully enclosed structure, which effectively prevents the external environment from invading the equipment. At the same time, the box transformer adopts advanced anti-condensation technology and high-quality materials, which reduces eddy current loss and hysteresis loss, and improves the reliability of the equipment.

3. Low loss

The pad-mounted transformer uses an energy-saving transformer to reduce the operating loss of the equipment. In addition, advanced energy-saving technologies and materials are used inside the box transformer to further improve the overall efficiency of the equipment.

4. Environmental protection and energy saving

The pad-mounted transformer adopts a fully enclosed structure, which effectively reduces noise and electromagnetic radiation and is environmentally friendly. At the same time, its energy-saving transformer and advanced energy-saving technology also reduce the energy consumption of the equipment, which is in line with the current environmental protection concept.

5. Easy to install and maintain

The pad-mounted transformer adopts modular design, which is easy to install and has a short construction period. In addition, the internal equipment layout of the box transformer is reasonable, which is convenient for daily maintenance and overhaul, reducing maintenance costs.

6. Waterproof and anti-corrosion

The shell of the pad-mounted transformer is made of ductile iron or stainless steel, which has good mechanical strength and corrosion resistance. In addition, the pad-mounted transformer is also equipped with a waterproof and anti-corrosion coating, which can be used for a long time in harsh environmental conditions.

7. Good flexibility

Pad-mounted transformers can be flexibly configured and combined according to user needs to meet the requirements of different power usage occasions. In addition, pad-mounted transformers can also be remotely monitored and controlled through remote control, automation, etc., which improves its intelligence.

Application scope of pad-mounted transformers

Pad-mounted transformers have been widely used in many fields due to their unique advantages and characteristics:

1. Urban distribution network transformation
