Details

Product category: product center oil immersed transformer

Product Description: low loss, low noise, stable and reliable

Low loss, low noise, low temperature rise and low partial discharge;

Compact structure design;

30-year life design;

The robot is fully automatic lamination and adopts a full inclined 45 degree 7-step seam structure;

Seven level temperature control technology to ensure safe operation.

Performance characteristics:

Adopt unique welding process, no leakage;

Cancel the high and low pressure lifting seat and reduce the weld; The tank wall adopts wide steel plate to reduce joints; Adopt unique welding process to ensure welding quality.

Groove structure

All sealing flanges adopt groove structure to ensure sealing performance.

Control leakage

All oil drain valves of the transformer adopt copper valves, and the radiator adopts vacuum butterfly valve to reduce the chance of transformer leakage.

Low loss and low noise

Adopt advanced technology and equipment at home and abroad and conduct professional research and development. The iron core adopts high-performance cold-rolled oriented silicon steel sheet and automatic robot lamination machine, with small shearing burr and low lamination coefficient, which effectively reduces the no-load loss, no-load current and noise of the transformer. The no-load loss is 5% ~ 15% lower than that of manual lamination.

high reliability

The transformer is equipped with an oil level thermometer, the top of the oil tank is equipped with a pressure relief valve with a contact, the oil level indicator with a contact is used for the oil level mark of the oil conservator, and the high and low voltage bushings are anti fouling reinforced pure porcelain oil type bushings, which can be used in heavily polluted environments.

High quality insulation framework support inside the coil

The coil is internally supported by high-quality insulating framework. All coils adopt internal and external braces, all braces and cushion blocks are chamfered, the electric field is uniform and the reliability is strengthened. All fasteners on the coil axial adapter body are self-locking locknuts, so that the product can withstand the bumps of long-distance transportation without looseness and hanging core.
