1. When performing maintenance on a 33kV 12 12.5 Mva 3 Phase Power Transformer, we prioritize the safety of all personnel on site. Please strictly follow the relevant operating procedures and safety measures to prevent accidents from occurring.
2. The maintenance of transformers should be carried out by professionals with relevant knowledge and experience. They can accurately assess the operational status and issues of transformers and take corresponding measures.
3. Maintenance should be carried out according to the predetermined plan to ensure regular maintenance. Adhering to the maintenance plan helps prevent malfunctions caused by negligence in maintenance.
4. The maintenance process and results of the 33kV 12 12.5 Mva 3 Phase Power Transformer should be recorded in detail. This includes maintenance dates, executed activities, test results, etc., for future analysis and reference.
5. During maintenance, preparations should be made to deal with emergency situations. This includes having necessary maintenance tools and spare parts, as well as contact information for maintenance services.
The iron core is made of cold-rolled oriented silicon steel sheets. The laminations are cut using GEORG fixed length cutting lines,
This cutting line has the functions of stepped stacking cutting and automatic stacking.
The multi-level laminated structure can reduce losses and noise.
The steel plates in the iron core column and yoke are clamped together with glass epoxy resin adhesive.
The conductor of the 33kV 12 12.5 Mva 3 Phase Power Transformer is made of high-quality enameled copper wire or paper wrapped copper wire, and the winding forms include:
Drum, spiral, improved spiral, continuous, and staggered to ensure insulation strength. The standard tape specification is ± 2 * 2.5% for high-voltage windings.
The fuel tank, fuel tank cover, and oil storage tank are all made of corrugated steel plates. Small transformers are used
Deep oil tank and oil tank cover, while large transformers use bell shaped oil tanks. The corrugated structure is an effective oil cooling method.
Fill the fuel tank with high-quality mineral oil that meets the IEC296 standard, without PCB or PCT.
Insulating oil is used to help cool transformers and provide insulation between some of the internal live parts.
Tap changers are used to regulate the output voltage of transformers to the desired level. We achieve this by changing the turns of the high-voltage winding to alter the transformer ratio in the system. The tap changer can be an on load tap changer (OLTC) or an off load tap changer (OCTC).
The active part of the transformer is assembled from the iron core and winding. The active part adopts multi winding and isobaric dry assembly method, effectively improving electrical strength and short-circuit resistance.
High tech equipment should be used and rigorously tested according to IEC standards, which ensures the quality and reliability of each of our 33kV 12 12.5 Mva 3 Phase Power Transformers.
