Abstract
The utility model discloses a control device enabling automatic switching on of a mains electricity supply after UPS failure in ingot casting production process. The control device comprises two circuit breakers, a UPS power supply, a switching power supply and an alternating current relay. A first circuit breaker is connected with a first contact of the alternating current relay; a second circuit breaker is connected with the UPS power supply; the UPS power supply is connected with a second contact of the alternating current relay; the second contact of the alternating current relay is connected into a PLC control system of an ingot casting furnace; an input end of the switching power supply is connected between the second contact of the alternating current relay and the PLC control system; an output end of the switching power supply is connected into a computer monitoring system of the ingot casting furnace; and a coil of the alternating current relay is connected with an output end of the UPS power supply. The control device of the utility model can satisfy emergency requirements in short-time power outage, and the same time, can assist in ensuring safe production after the UPS failure.
Description
Technical field
The utility model relates to the polycrystalline silicon ingot or purifying furnace technical field, automatically switches to the control device of civil power after particularly UPS lost efficacy in a kind of ingot casting production process.
Background technology
At present, PLC control system and the computer supervisory control system of our employed polycrystalline ingot furnace are all powered by the UPS uninterrupted power supply, as shown in Figure 1, in the situation of mains failure, our UPS can also continue continually provides the supply of the power supply more than hour to them, in the situation that guarantees to have a power failure in the short time, PLC control system and the computer supervisory control system of ingot furnace can work, thereby guarantee can to run without interruption according to original technique behind the incoming call.
But in present ingot casting production process, after in case UPS breaks down and lost efficacy, PLC control system and computer supervisory control system can not be worked, cause heating system, vacuum system, air-channel system and the heat-insulation cage jacking system of ingot furnace all can not work, thereby cause whole silicon ingot to be scrapped, more seriously may cause damage of equipment and casualties.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, the control device that automatically switched to civil power after UPS lost efficacy in a kind of ingot casting production process is provided, can satisfies the emergency of short time outage, can guarantee again can keep the safety in production after UPS lost efficacy.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the control device that automatically switched to civil power after UPS lost efficacy in a kind of ingot casting production process, comprise two circuit breakers, ups power, Switching Power Supply, also comprise AC relay, described the first circuit breaker is connected with the first contact of described AC relay, described the second circuit breaker is connected with ups power, described ups power is connected with the second contact of described AC relay, the PLC control system of the second contact access ingot furnace of described AC relay, between second contact and PLC control system of described Switching Power Supply input and incoming transport relay, the computer supervisory control system of described Switching Power Supply output access ingot furnace, the line bag of described AC relay is connected with the output of ups power.
As preferred version, be connected to fuse between described AC relay the second contact and the Switching Power Supply.
Compared with prior art, the beneficial effect that has of the utility model is: control device of the present utility model
CanSatisfy the emergency of short time outage, can make again ingot casting production behind the UPS malfunction and failure, can continue operation by continual process curve according to setting, guaranteed the safe operation of equipment and operating personnel's safety.

Fig. 2 is the utility model one embodiment circuit theory diagrams.
Embodiment
As shown in Figure 2, the utility model one embodiment comprises two circuit breakers 1 and 7, ups power 2, Switching Power Supply 4, also comprise AC relay 8, described the first circuit breaker 7 is connected with the first contact of described AC relay 8, described the second circuit breaker 1 is connected with the input of ups power 2, described ups power 2 is connected with the second contact of described AC relay 8, the PLC control system 6 of the second contact access ingot furnace of described AC relay 8, between second contact and PLC control system 6 of described Switching Power Supply 4 inputs and incoming transport relay 8, the computer supervisory control system 5 of described Switching Power Supply 4 outputs access ingot furnace, the line bag of described AC relay 8 is connected with the output of ups power 2.
Be connected to fuse 3 between described AC relay 8 second contacts and the Switching Power Supply 4.
Control principle of the present utility model is: circuit breaker 1 and 7 all closes in normal ingot casting production process, the line bag of AC relay 8 is charged, by normally opened contact and the fuse 3 of AC relay 8, ups power 2 provides power supply for PLC control system 6, computer supervisory control system 5.In case in process of production, ups power 2 catastrophic failures lost efficacy, the line bag meeting dead electricity of AC relay 8, and at this moment, the normally opened contact of AC relay 8 will disconnect, and ups power 2 will be stopped power supply.Simultaneously, the normally-closed contact of AC relay 8 will close, and PLC control system 6, computer supervisory control system 5 are connected to civil power by normally-closed contact and the circuit breaker 7 of fuse 3, AC relay 8, have guaranteed proceeding of ingot casting production.
