The investigation of quench behavior mechanisms in superconductors represents a critical bottleneck limiting the engineering application of superconducting technologies. For low-temperature superconductors (LTS), research on dynamic response characteristics under active heating-induced quench conditions has reached maturity, with active heating-based quench protection being extensively implemented in LTS systems. However, high-temperature superconductors (HTS) exhibit fundamentally distinct characteristics compared to LTS, primarily due to their significantly slower quench propagation velocities (2–3 orders of magnitude lower than LTS). While localized active heating in HTS has been widely investigated, substantial knowledge gaps persist regarding quench behavior under global active heating conditions. This study constructs an active heating experimental platform to systematically investigate voltage and temperature characteristics during globally induced quench processes in stacked HTS tape assemblies. The obtained results provide essential experimental foundations for establishing HTS-specific quench theoretical models and evaluating the feasibility of implementing active heating quench protection strategies in HTS systems.
