SCB11 dry-type power transformer to improve the SCB10 transformer standard specification products, it and SCB10 transformer appearance and structure are not different, the key difference is that the SCB11 dry-type transformer no-load loss will be lower than SCB10 transformer about 10%, SCB11 dry-type power transformer overall energy-saving effect is better than SCB10 transformer (transformer loss = transformer no-load consumption + transformer load loss).

Structure of SCB11 dry-type power transformer:

1. The coil is coiled or foil-wound with copper wire, improved by glass fiber, and the epoxy resin is poured without filler, vacuum drying, degassing, dehumidification, high impact toughness, short circuit resistance, and strong impact resistance.

2. The head and tail end of the high-voltage winding and the middle tap tap are made of copper insert embedded structure, with good rigidity, easy to adjust the gear, beautiful and neat.

3. The core is made of high-quality grain-oriented cold-rolled silicon steel sheets, and the 45-degree full-oblique multi-step joints. The surface layer is covered with resin insulating coating, which is resistant to moisture and cold, rust prevention and noise reduction.

4. The elastic parts are clamped between the core, the clamp and the coil to make the coil in a stable clamping situation to reduce noise.

5. The transformer is designed according to self-cooling, and a longitudinal ventilation channel is reserved inside the overall poured high (low) voltage coil cylinder wall, which can be equipped with forced air cooling equipment (cooling fan), and the output volume can be increased by 20% after the forced air cooling equipment is selected.

6. Equipped with a thermostat, a platinum resistance (Pt100) is placed in the embedded hole above the low-voltage coil. In order to detect the temperature of the transformer winding, start and stop the cooling fan, and provide fault alarm, overheating report and overheat tripping functions, it provides reliable overload protection devices for dry-type transformers, and then improves the operation safety of dry-type transformers.
