The small 10KV oil-immersed power transformer is relatively advanced in design, and has been greatly improved and improved in materials, structures and processes. The high and low pressure clamps are tensioned by steel straps or upper beams and beams, forming a solid frame structure that enhances the core clamping force and withstands the impact of transport. Strong anti-short circuit capability, beautiful appearance, reliable operation, low loss and low noise, reaching the advanced level of similar foreign products.
1. The oil-immersed transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current, and binds the iron core to ensure the tightness of the iron core and reduce noise.
2. The high and low voltage windings are wound with oxygen-free copper, and the low-voltage windings of 500kVA and below adopt a double-layer cylindrical structure. 630kVA and above adopt double helix or four-helical structure, and high-voltage winding adopts multi-layer cylindrical structure.
3, amorphous alloy transformer is a fully sealed structure, extending the service life, free of core, maintenance-free.
4. The measured noise value is lower than the standard. After the normal transmission of this series of transformers, the relevant parts and components can be installed without the inspection of the core, and the acceptance project test can be carried out.
