Abstract
This invention refers to improvement for electrical technology, especially refers to the improved protector for 220V power source tripping control circuit, which consists of step down transformer, power source activating switch, operation panel output signal photo coupling circuit, fuse, emergency tripping switch, operation panel control solid state relay and load control circuit. The power line of operation panel output signal photo coupling circuit is connected with fuse output end. When fuse goes out of order, the operation panel output signal photo coupling circuit does not work and the tripping signal indicates in cell control machine to guarantee normal production of electrolytic aluminium.
Description
Technical field
The present invention relates to the improvement of electrical technology, particularly relate to the improved protective device of a kind of electrolysis tank slot control machine 220V power source trip control circuit.
Background technology
The major control of slot control machine 220V power supply: the three phase mains open-phase protection in main power source tripping operation, the protective circuit, mainly do not close, main adhesion, auxilliaryly do not close, the break-make of auxilliary adhesion, electrical source of power, 220V power supply control anode lifting contactor, crust breaking electromagnetically operated valve, blanking electromagnetically operated valve, effect indicator light, effect warning etc.
The 220V power supply is exported after by the transformer step-down by the 380V power supply.220V power supply one road contactor coil KM1, KM2, KM3, KM4, electromagnetic valve coil BK1, BK2, FD1, FD2, JZH, effect relay and effect lamp.Another road connects to action plate and the light idol circuit U 9-1 of trip signal is provided, offers the working power of each relay S1, S2, S3, S4, S5, S6, S7, S8, S9 by fuse.If when main power source generation phase shortage or open circuit fault, send trip signal, slot control machine panel display power supply trip signal by U9-1 control.
Fuse is 0.75A in the real work, it often opens circuit in work and causes fault, light idol circuit does not have power-off signal in this case, slot control machine does not have the fault prompting, and master-control room does not have the fault information, and the operator also is difficult to find that slot control machine has fault, can't carry out normal crust breaking, blanking thereby cause, can't carry out normal anode lifting adjustment, can't notify effect and other abnormal conditions at once, when serious bakie can take place, even cause the person and equipment breakdown.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcoming that prior art exists; provide a kind of and at fuse fusing fault time idol circuit U 9-1 takes place and do not import power supply and do not work, slot control machine is the operation panel 220V power source trip protection device of display power supply trip signal at once.
Operation panel 220V power source trip protection device of the present invention; be achieved by following technical proposals; the present invention forms of the present invention being characterized as by step-down transformer, power on switch, operation panel output signal light idol circuit, fuse, emergency trip switch, operation panel control solid-state relay and each load control circuit: the power lead of operation panel output signal light idol circuit connects the fuse output.
Operation panel 220V power source trip protection device of the present invention with improve before the following beneficial effect of comparing: the power supply of light idol circuit U 9-1 improved receives the fuse output; when importing power supply, fuse fault time idol circuit U 9-1 do not work; slot control machine is the display power supply trip signal at once; can't carry out normal crust breaking when having prevented in the past the fuse fault; blanking; can't carry out normal anode lifting adjustment; can't notify the generation of phenomenons such as effect and other abnormal conditions at once; guaranteed the normal operation of aluminium electroloysis Intelligent Fuzzy Control system; for the ordinary production of electrolysis provides guarantee, improved economic benefit.Technical solution of the present invention is applicable to the slot control machine of all aluminium cells.
Description of drawings
Fig. 1 is preceding electrical principle schematic diagram for operation panel 220V power source trip protection device of the present invention improves;
Fig. 2 improves back electrical principle schematic diagram for operation panel 220V power source trip protection device of the present invention.
Wherein: 1, step-down transformer; 2, mains switch; 3, operation panel signal circuit; 4, fuse; 5, operation panel signal circuit light idol circuit power lead; 6, emergency trip switch; 7, the control solid-state relay of operation panel; 8, each load control circuit.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 1.U9-1, U7 in the operation panel flashlight idol circuit 3 among the figure, the power supply of U8-1, U8-2 are connected on before the emergency trip switch.
As shown in Figure 2.Operation panel flashlight idol circuit 3 power supplys among the figure are the wiring after improving.The present invention plants operation panel 220V power source trip protection device and forms of the present invention being characterized as by step-down transformer 1, power on switch 2, operation panel output signal light idol circuit 3, fuse 4, emergency trip switch 6, operation panel control solid-state relay 7 and each load control circuit 8: the power lead 5 of operation panel output signal light idol circuit connects fuse 4 outputs.
During work, export 220V voltage, one road contactor coil KM1, KM2, KM3, KM4, electromagnetic valve coil BK1, BK2, FD1, FD2, JZH, effect relay and the effect lamp of 220V power supply by step-down transformer 1 step-down by the 380V power supply; Another road offers U9-1, U7, U8-1, the U8-2 that operation panel output signal circuit is a light idol circuit by lead 5, and the working power of each solid-state relay S1, S2, S3, S4, S5, S6, S7, S8, S9 is provided by fuse 4 simultaneously.When main power source generation phase shortage or open circuit fault, operation panel signal circuit 3 does not have power supply not work, this signal is delivered to slot control machine programmable microcontroller interface chip by U9-1 with trip signal, sends instruction by this program and is passed to slot control machine panel display power supply trip signal.
