Substation engineer Li has been fretting over recent inspection reports—the 10KV Dry Type Transformer in the basement is alarming again, with condensation on the windings causing excessive partial discharge. While the previous Low Maintenance Dry Type Transformer replacement did reduce oiling and maintenance, dust accumulation in the vents is occurring at twice the expected rate. An attempt at an Energy Efficient Dry Type Transformer did save power, but surge voltages trigger protective shutdowns. Worst of all, the Dry Type Transformers, designed for industrial use, are simply too dust-resistant to withstand cement plant dust, resulting in three repair requests in just six months.

This iterative dry-type transformer is designed to handle the rigors of industrial work:

Three powerful measures

① The sandwich winding is coated with ceramic silicone, automatically forming a fireproof armor when exposed to fire.

② The cooling duct features built-in centrifugal dust removal, reducing dust accumulation by 80% compared to conventional low-maintenance dry-type transformers.

③ The intelligent inrush current suppression module can withstand 25% voltage surges.

Measured data from a chemical plant

1. 18% energy savings compared to a conventional 10kV dry-type transformer.

2. Winding temperature is 15°C lower than that of an Energy Efficient Dry-Type Transformer.

3. In workshops with high PM2.5 levels, the lifespan exceeds twice that of a Dry-Type Transformer for Industrial Use.

Maintenance Rules

① Vacuum the bottom damper monthly.

② Perform a partial discharge test before the rainy season.

③ Avoid direct use of compressed air on the windings.
