Zusammenfassung:The present invention relates to a connection system for connecting component sections of wind turbine blades, according to which one or more intermediate parts (2) formed by a complex structure defining end transverse partitions (2.1) and a central transverse partition (2.2), between which there extend columns (2.3) separated by openings (2.4), is arranged between the blade sections (1) to be connected, the openings (2.4) including short bolts or screws (3) that pass directly through the end transverse partitions (2.1) and long bolts or screws (3) that pass inside the columns (2.3), said bolts or screws (3) being screw-coupled to nut-like anchoring parts (4) housed in the material of the blade sections (1). Sistema de unión de tramos componentes de palas de aerogenerador, que se determina disponiendo entre los tramos (1) de pala a unir una o más piezas intermedias (2) formadas por una estructura compleja que determina unos tabiques transversales extremos (2.1) y un tabique transversal medio (2.2), entre los cuales se extienden columnas (2.3) que quedan separadas por aberturas (2.4), incluyéndose en las aberturas (2.4) unos pernos o tornillos (3) cortos que pasan directamente a través de los tabiques transversales extremos (2.1) y unos pernos o tornillos (3) largos que pasan por el interior de las columnas (2.3), acoplándose dichos pernos o tornillos (3) a rosca respecto de piezas de anclaje (4) a modo de tuercas alojadas en el material de los tramos (1) de pala.
