Frequently Asked Questions (FAQ)
Q:What are the criteria for determining when to replace an old transformer?
A:The load rate has consistently exceeded 80% and there have been frequent overloads; the losses under no-load and at full load are more than 20% above the standard; insulation has aged (with excessive dielectric loss values and deteriorated oil quality); serious faults have occurred (such as winding deformation and multiple-point grounding of the core); the energy efficiency grade is lower than level 3 and energy-saving renovations are not economically viable; it has reached the design service life (generally 20–30 years).
Q:What are the reasons for excessive noise when the transformer is operating? How can the noise be reduced?
A:Reasons: Loosening of core, deformation of windings, resonance of components, failure of cooling system, influence of grid harmonics. Measures: Tighten the core clamps; Correct the position of windings; Adjust the shock absorption devices of cooling fans / oil pumps; Install soundproof covers; Address grid harmonics.
Q:Why are dry-type transformers preferred for power distribution in high-rise buildings?
A:Dry-type transformers are oil-free and do not have the risks of oil leakage or explosion. They have high fire safety. The volume is relatively small, making them easy to install in the distribution rooms of buildings. The maintenance is simple and they meet the fire protection and space requirements of high-rise buildings.
Q:What are the special selection requirements for transformers that are matched？
A:It features low loss and low noise; the short-circuit impedance needs to match the inverter; it has strong resistance to voltage fluctuations and harmonic impacts; the transformer for photovoltaic power stations needs to adapt to significant changes in load throughout the day and night; the transformer for wind power needs to be able to withstand outdoor high-altitude and low-temperature environments, with a protection level of no less than IP54.
