Frequently Asked Questions (FAQ)
Q:How to clean the dust on the surface of the windings of a dry-type transformer?
A:After power outage, use dry compressed air (pressure ≤ 0.3 MPa) for blowing; stubborn dust can be gently brushed off with a brush; water or chemical cleaners must not be used; after cleaning, measure the insulation resistance again.
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: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.
