Integrated mutual inductor

The utility model relates to the technical field of mutual inductors, in particular to an integrated mutual inductor which comprises a shell, a plurality of coil grooves and through holes are formed in the shell, coils can be sleeved in the coil grooves, and the through holes correspond to the coil grooves one by one and are used for copper bars to penetrate through. According to the integrated mutual inductor, the plurality of coil grooves and the through holes are integrated on the shell, so that when the integrated mutual inductor and a three-phase copper bar are installed, the plurality of through holes synchronously penetrate through the three-phase copper bar, the tedious step of sleeving single-phase copper bars one by one is avoided, and the installation efficiency is multiplied. Meanwhile, a plurality of coil grooves are integrated on the shell, so that the size is reduced, the space is saved, and the applicability is improved. 本实用新型涉及互感器技术领域，具体是一体式互感器，包括壳体，所述壳体上设有多个供线圈套入的线圈槽，以及与所述线圈槽一一对应设置并用于供铜排穿过的通
