Description
Technical field the utility model relates to a kind of two DC power-supply circuit of energy-saving electromagnet.
Background technology is present, and a kind of new electromagnet supply power mode widely adopts, and is about to AC power and is converted to the high and low pressure two dc power supply through one group of power supply circuits and powers to solenoid, is respectively applied for the adhesive of electromagnet, sticking.It is little that this electromagnet has a volume, the advantage of economize on electricity.But there is following deficiency technically in the product of domestic existing this kind of employing supply power mode:
1. the high voltage direct current power supply realizes by the half-controlling bridged rectifier circuit, energy-saving electromagnet is a DC electromagnet, belong to bigger inductive load, its timeconstant=L/R (L, R are respectively inductance value, the resistance value of solenoid) is all about 30ms, the half-controlling bridged rectifier circuit is when this load of control, its controllability is obviously not enough, has and does not turn-off phenomenon, thereby often cause power supply circuits damage or solenoid to burn.
2. the ON time of high-voltage rectifying bridge is difficult for debugging, directly drive controllable silicon with differential or integrating circuit, because the discreteness of controllable silicon trigger parameter, add that trigger electrode pressure drop and equivalent resistance value have nothing in common with each other, cause the equivalent resistance value difference in differential or the integrating circuit, thereby causing the triggered time to have nothing in common with each other, this has brought certain difficulty for the batch process of product.
3. silicon controlled triggers and mostly is the constant current triggering, and this triggering form causes controllable silicon trigger electrode power consumption excessive, thermal accumlation.This also is one of reason of such power supply circuits fault.
Summary of the invention the utility model is primarily aimed at above-mentioned many deficiencies and is improved, and to form the new design of a kind of high-performance, high reliability, the technical scheme that is adopted is:
1. substitute the half-controlling bridged rectifier circuit with the better full-controlled bridge rectification circuit of controllability.
2. control the break-make of synchronous triggering signal with the time relay, and then control full-controlled bridge rectification circuit is to the high voltage direct current power supply of solenoid.
3. use the thyristor that triggers the full-controlled bridge rectification circuit with the synchronous pulse triggering signal of controllable silicon A, K utmost point operating voltage.
The beneficial effects of the utility model are: the controllable silicon triggering that is used for the high-voltage rectifying part is stable, reliable, and the power-on time debugging is easy, does not turn-off phenomenon and eliminates, the reliability raising of power supply circuits.Concrete scheme is as follows:
The two DC power-supply circuit of a kind of new energy-saving electromagnet include:
1. a step-down rectifier unit is made of transformer and rectifier bridge, is used for being rectified into Voltage pulsating direct-current supply after the AC power step-down, and a road direction solenoid is powered to keep the sticking of electromagnet, and the filtering voltage regulation unit is gone on another road.
2. a filtering voltage regulation unit is made of filter capacitor, current-limiting resistance and voltage-stabiliser tube, and being used for provides high-quality direct current supply to time relay unit with AC power after the pulse DC supply filtering behind the step-down rectifier unit, voltage stabilizing.
3. time relay unit, by wink motor time relay constitute, be used for controlling the break-make of synchronous triggering signal generating unit triggering signal.
4. a synchronous triggering signal generating unit is made of diode, current-limiting resistance and voltage-stabiliser tube, and trigger voltage signal is taken from controllable silicon A, the K utmost point of full-controlled bridge rectification circuit in the high voltage direct current feed unit, triggers this controllable silicon after current limliting, voltage stabilizing.When controllable silicon A, K pole tension enter positive half cycle, not during conducting, trigger voltage rises with controllable silicon A, K pole tension controllable silicon, until the controllable silicon conducting as yet.In case the controllable silicon conducting, the voltage of the extremely positive half cycle of its A, K descends immediately, thereby trigger current disappears.This has just formed and controllable silicon A, the synchronous pulse triggering signal of K utmost point operating voltage, is used for the triggering of each thyristor of full-controlled bridge rectification circuit.
5. high voltage direct current feed unit, its high-voltage rectifying partly adopt by the one-way SCR element constitute complete
The controlled bridge-type rectification circuit is used for and will provides attract current to solenoid after the AC power rectification.
Description of drawings is the utility model schematic block circuit diagram.1. step-down rectifier unit among the figure, 2. filtering voltage regulation unit, 3. time relay unit, 4. synchronous triggering signal generating unit, 5. high voltage direct current feed unit, 6. solenoid.
Below in conjunction with accompanying drawing the utility model is further specified: In the drawings, step-down rectifier unit (1) is with AC power rectification behind transformer pressure-reducing of 380 volts or 220 volts Become the low pressure Voltage pulsating direct-current supply, the one road delivers to solenoid (6) as the sticking power supply of electromagnet, another road Deliver to filtering voltage regulation unit (2), with voltage stabilizing after the pulsating direct current filtering, with form high-quality dc source to Time relay unit (3) power supply. Time relay unit (3) is used for the control synchronous triggering signal to be taken place The break-make of triggering signal in the unit (4). In the synchronous triggering signal generating unit (4), trigger voltage is taken from The controllable silicon A, the K utmost point that are used for high-voltage rectifying in the HVDC feed unit (5), after current limliting, voltage stabilizing, Trigger each thyristor. The effect of HVDC feed unit (5) is the interchange with 380 volts or 220 volts Directly to solenoid (6) power supply, make electromagnetic actuation behind the power rectifier.
The electromagnetic braking mechanism that embodiment is formed the utility model, energy-saving electromagnet and electromagnetic brake is applied to the braking of hoist engine in the hoisting machinery, electromagnet is a direct dynamic structure, rated attraction force 2500N, stroke 7MM, solenoid resistance value 50 Ω; Brake is a block brake, braked wheel footpath 300MM, braking moment 630NM, main spring counter-force 2500N.Supply power voltage is for exchanging 380 volts, when power connection, the wink motor time relay closing of contact in the power supply circuits, connect the synchronous pulse triggering signal in the synchronous triggering unit, make the conducting of full-controlled bridge rectification circuit, 342 volts pulse DC supply is provided to electromagnet coil then, make the electromagnet moving armature in the counter-force that overcomes brake main spring 2500N and adhesive after finishing the range ability of 7MM, brake opens, and brake is removed the braking moment of hoist engine.This moment, the wink motor time relay contact in the power supply circuits flicked, and the high voltage direct current power supply is closed, and the origin moving DC power supply of 12 deep-sited pulses of rectification of hanging oneself after the transformer step-down is powered to solenoid, to keep the sticking state of electromagnet.During dead electricity, the brake main spring counter-force of 2500N resets the electromagnet moving armature, and the braking moment of brake mechanism 630NM stops the hoist engine running of crane.Energy-saving electromagnet, electromagnetic brake known technology that the utility model embodiment is related, not shown in the accompanying drawing, will not narrate at this.
