Frequently Asked Questions (FAQ)
Q:Which type of transformer is more suitable for the power distribution in the community?
A:The box-type transformer is suitable for urban residential communities. It has a high degree of integration, occupies a small area, has a clean appearance and low operating noise. It can be directly placed in the green belts or power distribution rooms of the community. The pole-mounted transformer (tower-type transformer) is suitable for suburban or rural communities. It has a low cost and is easy to install. It is erected on utility poles and is suitable for scenarios with dispersed loads.
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: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.
