FIELD: electricity. ^ SUBSTANCE: when a common switch (23) is put on, power is simultaneously supplied to all windings. Due to electromagnetic forces developed by windings, all anchors will attempt to approach poles of appropriate electromagnets. However, since gaps between anchors and electromagnets differ, the highest electromagnet force will occur between an electromagnet (1) and an anchor (6). A head of its cylindrical rod, touching the rear surface of an anchor (7), will move the anchor towards an electromagnet (2), reducing the distance between it and the electromagnet (2). Similar action will be performed by all cylindrical rods, pushing appropriate anchors. When the distance between the anchor (7) is reduced down to the value equal to , the interaction force between this anchor and the electromagnet (2) will achieve the pull-in level, and the anchor (7) will start active motion, pushing all subsequent anchors. Then a gap (5) is set between an anchor (8) and an electromagnet (3). Entering the period of active motion, it will push all remaining anchors by value . The process will continue, and at the final stage the interaction between an anchor (10) and an electromagnet (5) becomes active. At the same time the process of motion itself will somewhat remind the start-up of a multi-stage rocket: each new connection of a subsequent electromagnet gives additional acceleration to a movable system of anchors. Therefore the latest stage of connection will move with higher speed compared to previous ones with an increased gap between its contacts. ^ EFFECT: increased range of anchor motion, increased gap between movable and fixed contacts, kinetic energy of an anchor in process of motion and efficiency factor. ^ 7 cl, 7 dwg |
