The invention discloses a spherical flue element equivalent model thermotechnical waterpower experimental apparatus comprising a pressure-bearing component, an electric heating component, an insulation component, a seal component, a pressure measurement component and the like, and field assembly and disassembly can be realized between the components. According to the spherical flue element equivalent model thermotechnical waterpower experimental apparatus, a banded fin thin rod bundle electric element is taken as an equivalent model structure of the spherical flue element, electrical heating method is realized, single-phase water flow and heat transfer experiment can be developed, and thermal-hydraulics of the spherical flue element can be reflected. The pressure measurement component can be assembled and disassembled on spot, consumables such as an O-shaped seal ring and a lead pressure pipe are convenient to replace, thereby reducing loss and cost. A grid spacer plays a role in transverse orientation for the banded fin thin rod bundle electric element, and a single-cone structure of the grid spacer can guide a plurality of the banded fin thin rod bundles to assemble, thereby reducing the difficulty of assembling and improving the efficiency of assembling. Copper braid is adopted to connect a lower conducting element and a lower conductive contact to realize flexible connection, so that the problem caused by electric component thermal expansion is effectively solved.
