TRANSFORMER-TYPE WATER ELECTRIC HEATER Russian patent published in 1998 - IPC

Abstract RU 2101882 C1

FIELD: electrical engineering. SUBSTANCE: electric heater is essentially three-phase transformer with spatial magnetic core. Its primary winding is connected to supply mains, and secondary winding consists of tubes positioned between magnetic core rods and short-circuited at ends with discs. Secondary winding along with body casing forms airtight chamber which accommodates magnetic core with winding. Water is heated in flow-through mode due to power generated in secondary winding when current flows through it. EFFECT: higher energetic, mass and dimensional indices. 1 wdgr
