| 简介 |
Useful model relates to the field of pulse engineering. In known pulse magnetizing installation (INU) is introduced built programmable device, connected to control unit (BU), connected to which are switching device (ku) with group of contactors, commutation unit (BK) with power switching device (ignitronom or thyristor), and also control panel (team). Power supply unit (for) is connected to the capacitive energy accumulator (ENE), which is connected through diode unit (databases) to BK , and inductor is connected to its output. At that power supply unit (for) is connected to network through ku by signal with BU and is disconnected from supply mains in voltage due to availability of feedback in this circuit. Feedback signal is generated in BU by signal from divider output, located in ku and connected to ENE. The specific feature of the proposed utility model is to use in INU microprocessor, digital-to-analog converter (TsAP), znakosinteziruyushchego device and keyboard for input charge voltage u.INU able to operate in manual and automatic mode by signals with personal computer (pc). In the INU control voltage 3 inENE with pitch 1c, the increased accuracy of control of magnetic field h i in working zone of inductor. In plant is additionally introduced relay (bp), the relay contacts are connected to team, and leads relay windings are connected to unit of control signals (beads). Plant is designed as for magnetizing, and for demagnetization of any, in T. h. highly koertsitivnykh permanent magnets (PM) from alloys of rare-earth metals (rare-earth metals). Stored in ENE energy discharges through databases and BK to inductor, where magnetization or unbuilding PM. Other field of application INU -successive magnetization, unbuilding and remagnetization PM bipolar magnetic pulse of for determining their magnetic characteristics. |
