The invention relates to a coil type longitudinal magnetic field contact assembly and a vacuum interrupter. The coil type longitudinal magnetic field contact assembly comprises a conductive rod and acontact piece. A contact base and a freewheeling contact disc are fixedly connected between the conductive rod and the contact piece. The contact base and/or the freewheeling contact disc is/are provided with at least two curved overcurrent arms extending outwardly from the center. Each curved overcurrent arm comprises inner and outer overcurrent arms which are arranged inside and outside respectively and extend in opposite directions. The inner and outer overcurrent arms are connected end to end. The overcurrent directions of the inner and outer overcurrent arms are opposite. According to thecoil type longitudinal magnetic field contact assembly, two inner and outer overcurrent arms with opposite overcurrent directions on the curved overcurrent arms generate magnetic fields in opposite directions; the overall longitudinal magnetic field of the contact assembly is increased, and at the same time the magnetic field strength of the central area is reduced; and the probability of ablation of the central part of the contact assembly is reduced.
