Abstract
The utility model relates to an enhancing electromagnet, in particular to a controller which starts the suction and work efficiency by an alternating current tractive electromagnet and can decreases the energy consumption and working noise and the utility model is composed of a starting current circuit, a holding current circuit and a switching control circuit. The utility model realizes the cutting off of the starting current through a controllable silicon; since the utility model is provided with a regulative circuit, the matched electromagnet has the advantages of continuously regulative traction force; if this controller matches with the present alternating current tractive electromagnet, it can not only stress in a large scale, but also prolong the service life.
Description
The utility model belongs to electromagnet, especially to the improvement of alternating current tracting magnet, moves to realize the energy-efficient low noise of electromagnet.
At present in the every profession and trade, the alterating and direct current magnet of using are done traction power more, DC electromagnet power wherein 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 Russian Patent SU1010667(DC electromagnet), the another kind of old-fashioned contactor of employing and the time relay cooperate starts electromagnet under full voltage, under low-voltage, work, energy-conservation and the afterburning effect of these two kinds of methods is all not remarkable, and the range of application of control circuit is little, only be applicable to low-voltage, the low capacity electromagnet.And suction is unadjustable in the electromagnet series at present, 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 provides a kind of 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, reinforcing that both can be by a relatively large margin, 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 works being enabled under the low-voltage under the full voltage to realize solenoid.Design one for this reason and finish the control circuit that starting current automatically cuts off, and realize adjustable continuously to starting current and electromagnet suction by its.
How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes:
Accompanying drawing be electrical schematic diagram of the present utility model wherein:
K: be starting switch.
KB is a power transformer, and N1 is a primary coil, and N2, N3 are secondary coil.
KG is and the suitable controllable silicon of electromagnet rated operational current that it and continued flow tube Z6 form the starting current circuit.
P2 is a thyristor gating circuit.
Z1-Z6 is a rectifier diode.
N2, Z1, voltage-stabiliser tube DW, current-limiting resistance R1 forms the power unit (Q) of control circuit.
J is the excitatory line bag of electromagnet.
Behind the closed starting switch K, BG2, BG3 is in conducting state, triggers controllable silicon work and supplies with the startup of J pulsating direct current causing electromagnet.Start the power factor to improve integrated circuit greatly owing to change AC starting into direct current, add that the effect of continued flow tube (Z6) can increase the startup gravitation of electromagnet widely within former specified coil power limited.Owing in thyristor gating circuit, be provided with a delay amplification circuit (by BG1, W1, C1, R2, R3, R4 composition), make the The whole control circuit carry out the automatic cut-out of triggering signal.Because C1 charging back voltage constantly raises and is directed at BG
1The time-delay conducting.Cause again after the BG1 conducting composite amplifier (BG2, BG3, R5, thus R6) by controllable silicon is turn-offed, starting current switch to the single sustain electric current (by N3, Z2, Z3, Z4, the bridge rectifier that Z5 forms is supplied with), electromagnet changes the operating on low voltage state at once over to.
By accompanying drawing as seen, regulate the charging interval that W1 can control capacitance C1, thereby realize time control, and then in certain limit, realize the adjustable continuously of electromagnet startup suction controllable silicon conducting and cut-out.Therefore, the user can adjust the startup suction of electromagnet according to actual operating conditions, can remedy the waste that causes too greatly at interval because of the series of products model to a certain extent to reduce unnecessary startup impact shock.
The utility model and existing domestic electromagnet match not only can save electric energy greatly, reduces noise, life-saving, and can increase substantially ability to work and the range of application that has electromagnet now.
The listed MQ1-25N of the being single phase ac of following table electromagnet add behind the controller with the Performance Ratio of the MQ1-25N single phase ac electromagnet that does not add controller and MZS1-45N three-phase alternating current electromagnet.
