Frequently Asked Questions (FAQ)
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.
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 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:What are the reasons for the three-phase voltage imbalance in the transformer?
A:The positions of the transfer switch are inconsistent; there is a short circuit between the windings (in a certain phase); the three-phase load is severely unbalanced; the system voltage is unbalanced across the three phases.
