Single phase pad mounted distribution transformers are key equipment in the “last mile” of low-voltage distribution networks. Its design takes into account safety, economy and environmental adaptability, and is widely used in urban and rural power distribution systems.
Introduction:
Single phase pad mounted distribution transformers support outdoor installation and is a single-phase power transformer. It can directly convert voltage, reducing medium-voltage distribution to a low-voltage level that can be used directly. It is suitable for residential areas, communities or small-scale projects. The fully sealed packaging shell is also very convenient to install.
Structural composition:
The single-phase box-type distribution transformer has a compact structure and mainly consists of the following parts:
Transformer body
The core is generally made of stacked silicon steel sheets, which can reduce losses.
It includes high-voltage windings and low-voltage windings, and the materials are copper or aluminum.
Metal casing
To prevent rain and dust, the casing needs to be made of anti-corrosion material. The casing needs to have an insulating layer. If required by the customer, it should be equipped with heat sinks and ventilation holes.
Internal auxiliary components
It needs to include a tap changer that can be adjusted to prevent voltage fluctuations.
Configure fuses to prevent short circuits.
Cooling system
Oil-immersed self-cooling, through the self-cooling zone of oil.
Application scenarios:
Residential communities: Provide 220V single-phase electricity for household users;
Commercial area: Low-voltage power supply for small shops and office buildings;
Rural areas: Distribution networks for scattered households;
Urban fringe areas: Regions with low load density and dominated by single-phase electricity consumption.
Main advantages:
The installation method is very simple and it can be placed directly. There is no need for overhead or underground design, which greatly reduces the construction cost.
The fully enclosed shell packaging eliminates the need for direct contact with electrified components, making it extremely safe.
Adapt to the environment of most regions and changes in temperature.
The maintenance cost is very low and it has a one-year warranty.
