FIELD: electricity. ^ SUBSTANCE: fixed electromagnets (1, 2, 3, 4, 5) are arranged one after the other in axial direction. Each electromagnet is equipped with a movable anchor, accordingly (6, 7, 8, 9 and 10). Number of electromagnets and anchors depends on the value of the required gap between the last electromagnet along with the movement of anchors and its anchor. Movable anchors (6, 7, 8, 9, 10) of electromagnets are installed relative to each electromagnet with a gap that differs by the value n, where is gap of the first anchor along the anchor movement, n is a multiplier with an electromagnet number, to which this or that anchor is related. All neighbouring anchors at both sides are connected to each other by means of a flat V-shaped spring (11, 12, 13, 14 and 15). Electromagnets are equipped with excitation windings (16, 17, 18, 19, 20). All electromagnets are rigidly connected to each other by means of a common frame from longitudinal non-magnetic planks that cover the whole system at the ends. Between an anchor and an appropriate electromagnet there are return springs installed. Each electromagnetic drive is equipped with a normally open contact. Fixed contacts are joined with planks, and movable contacts - with anchors. The distance between contacts differs by the value n. Each drive is equipped with normally closed contacts. ^ EFFECT: increased range of anchor movement, larger gap between movable and fixed contacts, increased kinetic energy of an anchor in process of movement. ^ 4 cl, 8 dwg |
