Prefabricated modular substation primary and secondary equipment and other functional units should achieve modulardesign, factory production, and reduce on-site workload; Toreduce the footprint, a three-dimensional station building modelshould be adopted to optimize the layout. The outercompartment of the prefabricated cabin should have goodsealing, with a protection level of no less than lP55, and shouldbe integrated with a complete temperature control system,condensation controlsystem,smoke alarm system, videomonitoring system, door opening alarm system and otherintelligent functions.
Product Description
Box type substation is an outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices. Its main functions mainly include the following aspects:
Voltage conversion: One of the core functions of a box transformer is to convert voltage, which can convert high voltage systems to low voltage systems, or vice versa. This conversion can meet the voltage requirements of different electrical equipment and distribution systems, ensuring the stable operation of the power system.
Power distribution: Box transformers can distribute electricity to multiple users or devices to meet the electricity needs of different users. Through reasonable power distribution, the box transformer ensures the power supply efficiency and stability of the power system.
Power transmission: The box transformer calibrates and regulates electrical energy to improve the quality and voltage stability of electrical energy transmission, ensuring the effective utilization of electrical energy. This helps to reduce power losses and improve the overall efficiency of the power system.
Protection function: The box transformer has various protection functions, such as overload protection, short circuit protection, high voltage protection, and low voltage protection. These protective functions can effectively prevent accidents such as fires, explosions, and electric shocks caused by electrical faults, and protect the safety of equipment and personnel.
Insulation and protection: The casing of the box transformer is usually made of high-strength insulation materials, providing sufficient insulation protection for electrical components. This design reduces the probability of safety accidents such as short circuits and fires between different circuits, enhancing the safety of the power system.
Sound noise control: Through optimized design and process flow, the box transformer reduces the magnetic induction noise and mechanical noise generated during operation, providing assurance for the quiet and stable operation of the system.
In summary, box transformers play a crucial role in the power system. They not only achieve voltage conversion and distribution, but also ensure effective transmission and safe use of electricity. At the same time, they provide various protection functions to ensure the stable operation of the power system.
