Dry Type Power Transformer | Dustproof Cabinet Design

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.

A:Reason: The oil quality has severely deteriorated, and the internal temperature has risen, causing the oil to carbonize; faults in the windings or the core have generated arcs, leading to the decomposition and carbonization of the oil. Treatment: Replace all the qualified transformer oil; remove the core and conduct an inspection to eliminate internal overheating or discharge faults.

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.
