Description
Technical field: the utility model relates to a kind of improvement of filling demagnetization power supply internal circuit configuration.
Background technology: at present the power supply that permanent magnetic material is filled demagnetization generally is made up of outside input/output unit 1, control system 2, detection system 5, charging system 3, energy-storage system 4, delivery system 6, protection system 7.As Fig. 1, operation principle is as follows: after the power supply that magnetizes receives instruction (charge, magnetize) by outside input-output system 1, after modulating alternating current, control system 2 control charging systems 3 are transformed into high voltage direct current to energy-storage system 4 chargings, when detection system 5 detects charging voltage and operation preset voltage when equating, control system 5 charge closing systems 3 stop charging and send waiting for and filling the demagnetization signal; At the same time, if the voltage that detection system 5 detects on the energy-storage travelling wave tube has the fluctuation of decline, control system 2 can start 3 pairs of energy-storage travelling wave tubes of charging system simultaneously and in time mend.Protection system 7 can be carried out limiting voltage and be detected, if charging system breaks down, protection system 7 can be cut off main A.C. contactor immediately and stop charging.After outside input-output system 1 receives the instruction of magnetizing, the circuits for triggering work of control system 2 control delivery systems 6, trigger the controllable silicon conducting with the energy releasing device of the electric charge on the energy-storage travelling wave tube in delivery system 6 to the external inductor coil abrupt release, produce powerful magnetic field at hub of a spool, fill that demagnetization work is instantaneous to be finished.The energy releasing device of delivery system 6 is discharged in series or parallel discharge pattern in generally using at present, the discharged in series pattern is end to end successively with respectively organizing coil in the magnetism-filling base, form cascaded structure, as shown in Figure 2, inductance coil induction reactance owing to serial connection when the capacitor group is discharged to it is very big, must can provide high voltage for obtaining bigger electric current, this is for magnetize power supply design and realize very difficult of condenser type.Common parallel discharge pattern is to be in parallel as shown in Figure 3 respectively forming inductance coil in the magnetism-filling base, the energy storage capacitor group is together to its discharge, though can obtain very big electric current, but because each inductance coil parameter can not be accomplished absolute unanimity, therefore the energy of coil acquisition is difficult to equilibrium, thereby cause the Distribution of Magnetic Field inequality, influence the effect that magnetizes.Demagnetize all the more so for filling of high coercive force permanent-magnetic material especially.
The utility model content: the utility model has been developed the magnetize balancing energy releasing device of power supply of a kind of high-voltage large current, it has less time constant, each inductance coil all has independent electric capacity that it is discharged, can make inductance coil moment by big and balanced electric current, thereby obtain equally distributed magnetic field.The utility model can obtain bigger electric current and not need high voltage, greatly reduces production cost, and the permanent magnetic material field intensity after magnetizing is even, balance, is suitable for high-precision commercial Application.The utility model is by a plurality of capacitor C
