Skid-mounted dry-type transformer does duty on coal mine
A dry-type transformer mounted on a mobile skid was recently supplied in a specialised application on a coal mine.
A specially designed, fit-for-purpose solution was required to meet the demands of the harsh environment of a coal mine.
The cast-resin dry-type transformer, supplied by Trafo Power Solutions, is cooled without oil, which makes it suitable for mobile use while also reducing the risk of fire hazards and environment pollution.
The 1 250 kVA dual-MV configuration allows the unit to be linked to either 11 kV or 6.6 kV supply.
The company explains that the unit was designed for a compact enclosure, while still allowing for sufficient air movement for cooling.
The cast-resin transformer is provided with Class H insulation rating for both medium voltage and low voltage windings
This insulation standard ensures that the transformer can withstand temperatures of up to 180 °C. The enclosure is designed to accommodate heat factors while also preventing the ingress of dust or water.
A high level of mechanical rigidity was built into the transformer itself, in order to accommodate the regular relocation of the mobile skid and reduce the impact of vibration and other forces while the equipment is moved.
Trafo Power Solutions asserts that it is able to provide various dry-type transformer enclosed solutions with a mobile skid, for a range of mining applications.
