Pull-in voltage-dividing low-heating direct-current electromagnet

According to the attraction voltage-dividing low-heating direct-current electromagnet, a coil is wound on a framework and installed in a cylindrical cavity formed by a shell and an end cover, and an elastic epoxy resin adhesive layer is arranged between the coil and the shell; the upper magnetizer, the magnetic conducting ring, the magnetic isolating ring and the lower magnetizer are assembled and welded to form a magnetic core pipe, the magnetic core pipe penetrates through the interior of the magnetic conducting coil assembly, and the magnetic conducting coil assembly is fixed through a thread structure by the fastening nut and the magnetic conducting coil assembly; the static pressure ring is fixed in the upper magnetizer through the spring protection cylinder, the pressure-bearing socket and the fastening nut; the separator is pre-pressed to the bottom of the upper magnetizer through a reset spring, and a blade impacting structure on the separator penetrates out of the bottom of the upper magnetizer.
