With the continuous advancement of new power system construction, large-scale grid connection of renewable energy, cross-regional power dispatch, and industrial power upgrades, higher standards are being placed on the performance and quality of core transmission and distribution equipment. As a core piece of equipment in power grid hubs, the Oil Immersed Transformer, with its excellent heat dissipation and voltage stabilization performance, has become a key piece of equipment in the 230kV high-voltage transmission network. Its manufacturing process directly affects the overall stability and reliability of the power grid.
Currently, the power equipment manufacturing field is undergoing continuous iteration and upgrading. For the harsh operating conditions of high-voltage transmission scenarios, the industry is constantly optimizing the production processes of core equipment. Compared to Dry Type Transformers, which are suitable for indoor and environmentally friendly distribution scenarios, Oil Immersed Transformers have more prominent advantages in high-voltage, high-capacity, and long-distance transmission scenarios. Relying on a mature insulation and heat dissipation system, it is adapted to complex outdoor transmission environments and the needs of long-term continuous operation.
The efficient operation of a complete transmission and distribution system cannot be separated from the synergistic empowerment of various supporting equipment. Box-type substations, as integrated core power distribution facilities, can be precisely adapted to main transformer equipment, enabling centralized management and control of power transfer and distribution. Meanwhile, high and low voltage switchgear plays a crucial role in grid on/off control and fault protection, forming a complete power transmission and distribution equipment system with various transformers and substation equipment.
The industry focuses on the core manufacturing process of high-voltage transformers, prioritizing optimization of three key modules: core, windings, and insulation structure. Through refined process control, the electrical strength, mechanical toughness, and thermal stability of the equipment are comprehensively improved, preventing problems such as insulation aging and structural deformation during operation. Continuously improving manufacturing technology and a complete equipment adaptation system will effectively enhance the grid's anti-interference capability and operational efficiency, providing a solid equipment guarantee for the consumption of new energy and the balanced transmission of power across regions.
