Description

Transfer a formula magnet charger

Technical field: the utility model relates to magnet charger, especially relate to a kind of high efficiency, low-power consumption, a high pressure accent formula magnet charger.

Background technology: magnet charger is to be used for permanent-magnet materials such as ferrite, iron boron and goods thereof are carried out magnetized production equipment, is widely used in loud speaker, motor, electroacoustic equipment, industries such as magnetic force apparatus.Because the development of modern science and technology, emerging in large numbers of new magnetic material, new electromagnetic product, higher to the requirement of magnetizing equipment, still there are problems such as efficient is low, power consumption big, unstable properties in state, inside and outside magnetizing equipment at present.Its main cause is: 1, current magnet charger all has only a kind of supply power mode, not that the power that magnetizes is not enough, be exactly that efficient is too low, directly to the logical magnetic machine of the coil electricity that magnetizes, the speed that magnetizes is fast by electrical network, but power is too little, magnetize for little Ferrite Material, boost to giving the capacitive magnetizing apparatus of coil power supply that magnetizes behind the capacitance energy storage, though can accomplish high-power magnetizing by transformer, but the speed of powering on reaches several seconds even tens seconds, and efficient is low; 2, the capacitive magnetizing apparatus of existing transformer-supplied, to electrical network is inductive load, isolate with electrical network, meritorious, inactivity in the process of magnetizing all will change into heat energy at mechanical internal consumption, and power consumption is big, organism fever, the coil heating that magnetizes needs the water circulation system refrigeration, the failure rate height, the cost height, the maintenance cost height; 3, existing high-power magnet charger is because the speed that powers on is slow, the cycle of magnetizing is long, power consumption is big, can only connect the workbench that magnetizes, efficient is low, someone shifts at the continuous current circuit series resistor of the coil that magnetizes or inductance coil and bears the part power consumption, and this still can not reduce Overall Power Consumption, and the coil that is connect more can not independently magnetize; 4, existing magnet charger all is to regulate the voltage that magnetizes to regulate the intensity that magnetizes, with the non-linear relation of the intensity that magnetizes, instability, the advantage that can not keep high pressure to magnetize.

Summary of the invention: the purpose of this utility model is for solving the deficiency of above-mentioned existing magnet charger, and provide that a kind of high speed powers on, efficient operation, energy-conservation, accent field formula magnet charger that low consumption does not need water-cooled.High speed of the present utility model, low-power consumption, twoly magnetize, transfer a formula magnet charger to comprise: the power supply circuits of two-way parallel connection, the capacitor energy storage circuit of a variable capacity, the charge circuit of two-way parallel connection.It is characterized in that: it has a routing resistance R ₁With diode D ₁D ₂D ₃The circuit that the power supply circuits of series connection and a route step-up transformer boost and power is formed continual associating power supply circuits by orderly combination.Storage capacitor capacity regulating of the present utility model is with K switch ₁, K ₂, Kn respectively with C ₁, C ₂, Cn series connection back and receiving on the capacitor C, with the method that changes stored energy capacitance, reach the purpose of regulating the magnetic field of magnetizing.Two-way charge circuit of the present utility model, by the coil that magnetizes of two series connection of two SCR control, two coils can be controlled independently separately and magnetize, and do not have freewheeling circuit on the coil that magnetizes respectively.

The utility model high speed, low-power consumption, the two design principles of filling the platform magnet charger of accent field formula:

1, the principle of power supply circuits is: utilize resistance, diode and stepup transformer in the power supply circuits to constitute the push-pull type working method, formation moves the electronic compensating supply network, the reactive power that absorbs electrical network is given high-voltage capacitor charging, reaching ultrahigh speed powers on, do not consume active power again, do not influence the operate as normal of other electrical equipment on the electrical network, saved electric energy.In the moment of magnetizing, earlier provide high pressure to the coil power supply that magnetizes by storage capacitor, after direct power supply circuits are drawn in, make direct power supply cross the zero impedance district, reduced impact to electrical network.The method that is magnetized synchronously by storage capacitor discharge and the direct power supply of electrical network has strengthened the intensity that magnetizes greatly like this, is equivalent to 1.5 times with the capacitive magnetizing apparatus of capacity.

2, transferring the formula mode that magnetizes, is to utilize the capacity that changes storage capacitor to change the electric current that magnetizes, and the high voltage that keeps magnetizing is constant, so regulated quantity is linear with magnetic field intensity, makes the stable performance of magnetizing, and pulse front edge is pretty on foot, and the effect of minimizing power consumption is also arranged simultaneously.

3, become in parallel state with storage capacitor with power supply circuits (1) with the coil series connection back of magnetizing by a controllable silicon at charge circuit, it has saved freewheeling circuit, and the magnetic field energy of the coil that will magnetize directly returns electrical network through the circuit that powers on, and the big I of feedback quantity is by (R ₁) regulate, the power consumption that has significantly reduced body like this and filled platform has been saved electric energy, because it is low in energy consumption, fast several times of the speed that powers on is worked simultaneously so the utility model can be realized two charge circuits, the magnetize magnet charger of function of Cheng Shuan.Because there is not freewheeling circuit, energy directly reclaims, and does not need time of afterflow, does not also have the afterflow power consumption, and the back edge of the feasible pulse of magnetizing is also pretty on foot, and the working pulse width has only the pulsewidth about 1/10 that magnetizes of the magnet charger of existing home and abroad.So significantly reduced the heating of the coil that magnetizes, make the coil that magnetizes when any high strength magnetizes, not need hydrologic cycle cooling system, system's construction and maintenance cost had so both been saved, also overcome the water-cooled coil that magnetizes and easily caused the problem of leaking and scrapping, prolonged the useful life of the coil that magnetizes greatly by aqueous corrosion.
