Single phase pad mount transformer is a device used for power distribution, mainly in underground residential and commercial power distribution systems, and plays a role where safety, reliability and aesthetics are particularly important.
Introduction:
Single phase pad mount transformer is a single-phase distribution transformer installed on an outdoor ground base, typically used to reduce medium voltage to low voltage, providing single-phase power supply for residential areas, commercial areas or small industrial facilities. Its features include full enclosure, anti-electric shock, and adaptability to outdoor environments. It is a key device in the power distribution system.
Main features:
Safety protection
The fully enclosed design prevents direct contact of personnel with live parts and meets the IP67 protection level.
Easy to install
It can be directly fixed on the concrete base without the need for distribution poles, saving space.
Strong environmental adaptability
It can withstand extreme temperatures ranging from -30℃ to +40℃, and is moisture-proof and salt spray-proof.
Low noise
It adopts noise reduction design, and the operating noise is usually below 50dB.
Simple maintenance
Some models are equipped with oil level observation Windows and pressure gauges, facilitating daily inspections.
Typical application scenarios:
Residential area power supply: Provide single-phase power for single-family houses, communities, etc.
Commercial facilities: such as convenience stores, small shopping malls, street lamp power distribution, etc.
Rural power grid: Suitable for rural areas with distributed loads.
Temporary power supply: Temporary power demand for construction sites, event venues, etc.
Structural features:
Core and winding
The laminated core is adopted, and the core joints are stepped lap joints to enhance efficiency and reduce noise. Windings typically adopt a “low-high-low” structure to enhance short-circuit strength, efficiency and thermal strength.
Shell
It is equipped with multiple capping fixtures to ensure good sealing and reduce water accumulation at the edge of the cap. High-voltage bushings can be installed on the cover or side wall as required, while low-voltage ones use plug-in or clamp-type terminals.
Other components
Equipped with an automatic self-sealing pressure relief valve, a surge arrester bracket can be provided.
