CORE-FORM TRANSFORMER WITH LIQUID COOLANT FLOW DIVERSION BANDS

摘要

2149531 9412993 PCTABS00032 A core-form transformer winding (21) with liquid coolant flow diversion bands (60) is disclosed. The apparatus includes a winding tube (22) with a central longitudinal axis. A number of coil sections (26) are axially displaced along the central longitudinal axis of the winding tube (22). Radial ducts (45) are formed between the coil sections (26). Internal vertical ducts (30) are formed within each of the coil sections (26). A liquid coolant is used to cool the windings during operation. Flow diversion bands (60) are placed around every other coil section (26). The flow diversion bands (60) generate a partial blockage of the liquid coolant, which produces a radial flow into one or more of the radial ducts (45), resulting in vertical flow through the internal vertical ducts (30).
