Frequently Asked Questions (FAQ)
Q:What are the handling methods for oil leakage in the high-voltage bushing of a transformer?
A:Minor leakage: Tighten the flange bolts of the casing and replace the sealing gasket; Severe leakage: Replace the casing after power outage; If the insulation inside the casing gets damp, conduct an insulation test and replace the casing if necessary.
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.
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.
