YB□-12/0.4 (European style) outdoor prefabricated substation

YB series prefabricated substation is a complete set of power distribution equipment that compactly combines high-voltage electrical equipment, transformers and low-voltage electrical equipment. It is designed for various places such as urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mines and oil fields, and temporary construction electricity. It is mainly used to receive and distribute electric energy in the power distribution system. The design concept of this substation is to improve the efficiency and safety of power distribution and meet the needs of modern urban and industrial development.

    Product Introduction

    YB prefabricated substation has the remarkable characteristics of strong completeness, small size and compact structure. Compared with conventional civil substations, the floor space of box-type substations with the same capacity is usually only 1/10 to 1/5 of that of conventional substations. This advantage greatly reduces the design workload and construction workload, thereby effectively reducing construction costs. The YB series substation is safe and reliable in operation, easy to maintain, and has mobility, which can flexibly adapt to different usage scenarios and needs.

     

    In the power distribution system, the YB prefabricated substation can be used not only in the ring network distribution system, but also in the dual power supply or radial terminal distribution system, showing extremely high adaptability and flexibility. This makes it a new set of equipment in the current construction and renovation of urban and rural substations, which can effectively support the modernization and upgrading of power infrastructure.

     

    The YB prefabricated substation complies with the national standard GB/T17467-1998 "High-voltage/Low-voltage Prefabricated Substation", ensuring safety and reliability during its design and manufacturing process. Compliance with this standard not only enhances the market competitiveness of the product, but also provides users with greater confidence, ensuring its stability and efficiency in practical applications. Through these superior performances, the YB series prefabricated substation has shown a wide range of application prospects and important market value in the field of power distribution.

    Structural features

    This product is connected by a high-voltage distribution device, a transformer and a low-voltage distribution device, and is divided into three functional compartments: a high-voltage room, a transformer room and a low-voltage room. The high-voltage room and the low-voltage room are fully functional and can support a variety of power supply methods, including ring network power supply, terminal power supply and dual power supply, etc. At the same time, high-voltage metering components can be installed to meet the needs of high-voltage metering. The transformer room can choose low-loss oil-immersed transformers or dry-type transformers such as S9 and SC series to ensure high efficiency and reliability. According to the specific requirements of the user, the low-voltage room can adopt a panel or cabinet-mounted structure to provide power distribution, lighting distribution, reactive power compensation, electric energy metering and electricity measurement and other functions to meet the different needs of users, facilitate power supply management and improve power supply quality.

     

    The high-voltage room has a compact and reasonable structure design, and is equipped with comprehensive anti-misoperation interlocking functions to ensure safety. When required by users, the transformer room can be equipped with tracks to facilitate the transformer to enter and exit from the two side doors. Each compartment is equipped with automatic lighting devices to ensure good lighting in any situation. In addition, all components selected for the high-voltage and low-voltage rooms are reliable and easy to operate, ensuring safe and reliable product operation and convenient maintenance.

     

    This product adopts both natural ventilation and forced ventilation. The transformer room and high and low voltage rooms are equipped with ventilation ducts. The exhaust fan equipped with a temperature control device can automatically start and shut down according to the set temperature to ensure that the transformer operates within the normal temperature range.

     

    The box structure design can effectively prevent rain and dirt from entering. The material is made of colored steel plates, which have anti-corrosion and heat-insulating functions, ensuring that it can adapt to long-term outdoor use conditions. It has good anti-corrosion, waterproof and dustproof properties, extending its service life. At the same time, it has a beautiful appearance and meets modern design requirements.
