Description

High-effect energy-saving electromagnetic iron controller

The utility model is a kind of high-efficiency, energy-conserving and electromagnetical rail controller, belongs to electromagnet, especially to the improvement of alternating current tracting magnet, moves to realize the energy-efficient low noise of electromagnet.

Generally adopt alterating and direct current magnet to do traction power at present, wherein DC electromagnet power is less, though the alternating electromagnet power bracket is bigger, but the reactive loss in the work is big, power factor is low and vibration and noise arranged, and adopts electromagnet to add the method for control circuit usually on to the reinforcing of electromagnet and energy-conservation improvement.Roughly be divided into two kinds: a kind of is the capacitor charge and discharge that utilizes control circuit, makes the electromagnet reinforcing and compensates power consumption.Augmentor as RUSSP SU1010667(DC electromagnet), the another kind of old-fashioned contactor and the time relay of adopting cooperates, electromagnet is started under full voltage, work under low-voltage, the energy-conservation and afterburning effect of these two kinds of methods is all not remarkable, and the control circuit range of application is little, only be suitable for low-voltage, low capacity electromagnet, and suction is unadjustable in the present electromagnet series, often is under the situation of choosing less than appropriate size, and low load with strong power causes the strong noise operation.

The purpose of this utility model, just provide a kind of electromagnet rail controller, be applicable to the electromagnet of certain stroke or power bracket or make a kind of electromagnet that the startup of certain limit be arranged, adhesive power, both can be significantly afterburning, tangible power savings is arranged again, and it is adjustable continuously to realize starting suction within the specific limits, realizes the low energy consumption noiseless operation.

Basic design of the present utility model is that the power supply circuits with electromagnet coil are divided into the starting current circuit and keep current circuit two parts.Automatic cut-out is set in the starting current circuit under big electric current, starts, under little electric current, work to realize solenoid.Designed one for this reason and finished the control circuit that starting current cuts off automatically, and realized adjustable continuously to starting current and electromagnet suction by its.

The utility model and existing homemade electromagnet match not only can save electric energy greatly, reduces noise, increases the service life, and can increase substantially the ability to work and the range of application of existing electromagnet.

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes:

R5＝120KΩ；C1＝22～47Uf／16V；C2＝0.22～0.8Uf

The L3-actuating coil; L1-keeps coil

Behind closed K, BG2 is in conducting state, triggers controllable silicon work, causes that electromagnet starts for pulse direct current of L3, starts the power factor that can improve integrated circuit greatly owing to change AC starting into direct current, adds continued flow tube Z5; The effect of Z6 can increase the startup gravitation of electromagnet widely within former specified coil power limited.Owing in control circuit, be provided with a delay amplification circuit (by BG1; C1; R1; R2; Z7 forms), make the The whole control circuit carry out the automatic cut-out of triggering signal, because constantly raising, C1 charging back voltage causes BG1 time-delay conducting, cause again ending of BG2 after the BG1 conducting, thereby controllable silicon is turn-offed, starting current is cut off, and is the single sustain electric current, and electromagnet changes little current work state at once over to.

By accompanying drawing 1 as seen, regulate the charging interval that adjustable resistance R1 can control capacitance C1, thereby realize time control to controllable silicon conducting and cut-out, thereby realize that in certain limit electromagnet starts the adjustable continuously of suction, therefore the user can adjust the startup suction of electromagnet according to actual operating conditions, to reduce unnecessary startup impact shock, can remedy the waste that causes too greatly at interval because of the series of products model to a certain extent.

The work block diagram of the utility model in the magnet control system, as shown in Figure 3, wherein 1,2 is wiring of input power source, and 3,4,5 join with the two ends of coil respectively, and " 3 " are common port.

Press the designed circuit structure diagram of the schematic diagram of Fig. 1 as shown in Figure 2, figure Central Plains device is corresponding one by one with former device shown in Figure 1." 1 " " 2 " are power input among the figure, connect 220 volts of AC power, and " 3 " " 4 " " 5 " are the output that is connected with electromagnet.

Can be screwed in control box by printed circuit board (PCB) shown in Figure 2, also can use epoxy encapsulation, controllable silicon KG will be exposed to outside the encapsulating material during encapsulation, so that heat radiation.
