6300KVA oil immersed transformer

　　6300KVA Oil-Immersed Transformer: A High-Capacity Power Equipment

　　I. Structure and Components

　　Core and Windings

　　The core is constructed from high-permeability cold-rolled grain-oriented silicon steel sheets to reduce hysteresis and eddy current losses.

　　Windings are composed of conductor coils wound around the core and insulated using paperboard barriers and shielding layers. The insulation thickness increases with the voltage level.

　　Tank and Insulating Oil

　　The tank is welded from steel plates and filled with transformer oil, which serves as both insulation and cooling medium.

　　The insulating oil has excellent thermal conductivity, effectively dissipating heat generated during transformer operation and ensuring the temperature remains within safe limits.

　　Other Key Components

　　Include an oil conservator, insulating bushings, tap changers, and Buchholz relays, which collectively ensure the safe operation of the transformer.

　　II. Performance Characteristics

　　High Capacity and Efficiency

　　The 6300KVA rating represents the transformer's rated output power, capable of meeting large-capacity power demands.

　　High-quality materials and advanced manufacturing processes are employed to reduce no-load and load losses, enhancing operational efficiency.

　　On-Load Tap Changing Capability

　　Some models (e.g., SZ13-6300KVA/35KV) feature on-load tap changing technology, enabling continuous and smooth voltage regulation under load conditions to ensure stable and accurate voltage output.

　　Excellent Heat Dissipation and Insulation Performance

　　The oil-immersed design allows heat generated by the windings and core to be first converted into thermal energy in the insulating oil, which is then dissipated through oil convection cycles, ensuring the transformer operates within a safe temperature range.

　　III. Application Scenarios

　　Urban Grids and Industrial Enterprises

　　Widely used in the power systems of urban grids, industrial enterprises, and large power plants as core equipment for distribution or substation applications, facilitating voltage transformation and power transmission.

　　High-Voltage Distribution Systems

　　Suitable for high-voltage distribution systems up to 35KV, meeting the demands of various high-voltage grids and enhancing power transmission efficiency.

　Special Environmental Applications

　　Such as mine transformers, capable of providing reliable power distribution in remote or harsh environments.

　　IV. Technical Parameters and Standards

　　Rated Capacity and Voltage Levels

　　The rated capacity is 6300KVA, with voltage levels customizable according to actual requirements, such as 35KV or 10KV.

　　Losses and Impedance

　　No-load and load losses comply with national standards such as GB10228-2015, with impedance voltage typically ranging between 4% and 7%.

　　Protection Class and Environmental Adaptability

　　The protection class can reach IP00 or IP21, with an operating ambient temperature range generally of -45℃ to +45℃ and an altitude limit of ≤3000 meters.
