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 issues should be noted when connecting the transformer to the distribution cabinet?
A:Use copper busbars or cables for connection, with the conductor cross-section meeting the current-carrying requirements; the connection points need to be treated with tin plating or silver plating to reduce contact resistance; install lightning arresters and disconnect switches on the high-voltage side to facilitate maintenance; add insulating covers for the busbars on the low-voltage side and mark the phase sequence; after connection, check the insulation and phase sequence to ensure there are no errors.
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.
