Description

The rolling electricity is restarted controller

Technical field

The utility model rolling electricity is restarted controller and is belonged to electric automatization control field, the particularly a kind of controller that can restart motor when sending a telegram here again after causing power network fluctuation to stop because of a variety of causes.

Background technology

Electrical network is because thunderbolt, short circuit, power plant failure and other inside, external cause cause the floating greatly degree fluctuation of voltage, even the phenomenon of the several seconds that has a power failure happens occasionally, and this phenomenon is commonly called as rolling.When the rolling electrical phenomena takes place, motor and other electric equipment meeting automatic stopping with contactor control power supply, even send a telegram here immediately, motor can not work on yet, cause technology continuous operation process to be interrupted, the a large amount of material emptyings of the lighter are scrapped, and weight person causes accidents such as device damage, blast, fire, brings about great losses to enterprise.

Summary of the invention

The utility model rolling electricity is restarted controller, for industrial enterprise solves because of power network fluctuation parking development and Design.Restart motor in the time of can after power network fluctuation stops, sending a telegram here again, do not change former control loop during installation, do not influence former control program.The utility model anti-shake electric controller has only four binding posts, and a, b terminal connect power supply, and c, d terminal connect contactor starting auxiliary contact, seldom take the contactor auxiliary contact.When moving, do not restart former control loop protection component.

The technical scheme that its technical problem that solves the utility model adopts is to comprise power subsystem, start unit, timing unit, binding post; Power subsystem is made up of transformer, rectifier, capacitor C 3, and the transformer primary side is connected on the control power supply, direct current output 6V; Start unit is made up of relay J 1, J2, capacitor C 1, J1 coil two ends are connected on the both positive and negative polarity of DC power supply respectively, C1 is with after the normally closed point of J1 is in parallel, its positive pole connects positive source, one end of another termination J2 coil, the other end of J2 coil links to each other with triode T collector electrode, and normal battle of J2 often made war in parallel with the contactor self-locking; Timing unit is made up of triode T, capacitor C 2, resistance R 1, R2, R3, relay J 3, after R1, R2, R3 one end link to each other, another termination capacitor C 2 positive poles of R3, the C2 negative pole connects power cathode, another termination transistor base of R1, and transistor emitter connects power cathode, R2 links to each other with the normal end of making war of J3, J3 another termination dc power anode of often making war, the former limit of a termination transformer of J3 coil, another termination J2 is often made war.Binding post is made up of a, b, c, d, and a, b connect the control power supply, and c, d connect contactor and often make war.

The beneficial effects of the utility model are to restart motor can send a telegram here after power network fluctuation stops the time again, and circuit is simple, easily make, volume is little, easy for installation, and wiring is simple.

Description of drawings

As Fig. 1 is that the utility model rolling electricity is restarted controller use circuit theory diagrams, the 1st, DC power supply, the 2nd, filter capacitor C3, the 3rd, relay J 1 coil, the 4th, triode T, the 5th, adjustable resistance R1, the 6th, capacitor C 2,7th, resistance R 3,8th, resistance R 2, the 9th, relay J 3 is often made war, and the 10th, relay J 3 coils, the 11st, the normally closed point of relay J I, the 12nd, capacitor C 1,13rd, relay J 2 coils, the 14th, relay J 2 is often made war, the 15th, the contactor CJ of often making war, the 16th, contactor coil CJ.

Restarting controller below in conjunction with 1 pair of the utility model rolling of accompanying drawing electricity uses circuit theory to be illustrated.

Embodiment

Motor contactor when running status CJ (15) closure of often making war, relay J 3 (9) closure of often making war, direct current charges to C2 (6) by R2 (8), R3 (7).Relay J 1 (3) gets electric adhesive, relay J 1 normally closed point (11) disconnects, direct current passes through relay J 2 coils (13), triode T (4) to capacitor C 1 (12) charging, and capacitor C 1 (12) is full of electricity back relay J2 coil (13) outage, and promptly relay J 2 is often made war (14) in the disconnection position.Relay J 1 coil (3) dead electricity when power network fluctuation, relay J 1 normally closed point (11) closure, give capacitor C 1 (12) discharge, the contactor CJ (15) of often making war disconnects, relay J 3 often make war (9) disconnect, capacitor C 2 (6), resistance R 3 (7), resistance R 1 (5), triode T (4) base stage are formed discharge loop, keep triode T (4) base stage that bias voltage is arranged.Voltage recovers relay J 1 coil (3) adhesive just often, and relay J 1 normally closed point (11) disconnects.Direct current is added between the collector electrode and launching base of triode T (4) by capacitor C 1 (12), relay J 2 coils (13), because of triode T (4) base stage has bias voltage, triode T (4) conducting, relay J 2 coils (13) adhesive, relay J 2 (14) closure of often making war, give contactor CJ coil (16) starting impulse signal, contactor CJ coil (16) energising adhesive, motor is realized restarting.

After capacitor C 1 (12) charging finishes, relay J 2 coils (13) outage.After contactor CJ coil (16) adhesive, capacitor C 2 (6) is recharged, for next voltage fluctuation is prepared.

Start-up time delay is regulated resistance R 1 (5) scalable delay time by resistance R 1 (5), resistance R 3 (7), capacitor C 2 (6) size decisions.The starting impulse width is by capacitor C 1 (12) decision.

As seen as long as power network fluctuation and interruption duration are no more than the discharge time of resistance R 1 (5), resistance R 3 (7), capacitor C 2 (6) decisions, when restoring electricity, relay J 2 often make war (14) send a pulse signal and restart motor.
