Operating Principle & Maintenance Guide of oil filled transformers
Operating Principle:
oil filled transformers utilize electromagnetic induction for voltage conversion, with insulating oil serving dual cooling/insulation functions
three phase oil immersed transformers employ symmetrical three-phase magnetic circuits for balanced loading
Maintenance Guide:
Routine Checks: Monthly inspection of oil level indicators for oil filled distribution transformers
Oil Management: Test dielectric strength of insulating oil in three phase oil immersed transformers biennially
Fault Response: Shut down oil filled transformers immediately if temperature exceeds 85°C
Professional Maintenance: Triennial comprehensive checks including bushing seal tests and winding resistance measurements
Environmental Requirements: Maintain 1m clearance around oil filled distribution transformers for ventilation
