POLARISED ELECTROMAGNETIC RELAY WITH MAGNETIC LATCHING FOR A TRIP DEVICE OF A CIRCUIT BREAKER |
摘要 |
The invention relates to a polarized electromagnetic relay with magnetic latching and sliding armature. The magnetic circuit comprises a tubular frame enclosed by two flanges (22, 24), a permanent magnet (14) with axial magnetization fitted between one (22) of the flanges and a flux-diverter (26), and a cylindrical trip coil (30) mounted on a bushing inside the frame (20). The other flange (24) is fitted with a tubular sleeve (46) made of ferromagnetic material coaxially surrounding a part of the moving armature (16) with a uniform radial air gap (jl) interposed. The axial overlapping distance (L) of the armature (16) by the sleeve (46) in the latched position of the relay (10) is greater than the thickness (11) of the flange (24) and/or than that of the frame (20). |
