According to the invention a resistive current limiter contains an electrically insulating support element (3) and at least one printed conductor structure (10) positioned thereon which comprises a printed conductor (11) made of a high-Tc superconductive material. The printed conductor has straight and curved sections (11g and 11b, respectively). In the curved sections (11b) a maximum internal radius/external radius ratio v of 7 is to be maintained (v = ra/ri, where ra = external radius, ri = internal radius). The printed conductor (11) is advantageously obtained by structuring from a layer made of the high-Tc superconductive material which has been deposited on the support element (3).
L'invention concerne un limiteur de courant résistif qui contient un corps de support (3) électro-isolant sur lequel est disposée au moins une structure à piste conductrice (10) comportant une piste conductrice (11) en matériau supraconducteur à haute température de transition T¿c?. Ladite piste conductrice présente des sections droites et des sections courbes (11g ou 11b). Pour les sections courbes (11b), il faut maintenir un rapport rayon extérieur/rayon intérieur v de 7 (v = r¿a?/r¿i? où r¿a? = rayon extérieur et r¿i? = rayon intérieur). La piste conductrice (11) est, de préférence, obtenue par structuration d'une couche constituée dudit matériau supraconducteur à haute température de transition T¿c?, appliquée sur le corps de support (3).
