AI Technical Summary
In the incinerator process, when the power outage of the entire factory in the incinerator, the furnace body temperature needs to drop steadily, and the power supply of the cooling fan and waste heat boiler replenishing water pump cannot be interrupted, otherwise it will lead to uneven heating of the incinerator, which may cause the risk of cracking and collapse.
An emergency power supply device is designed, through the redundant connection of the power distribution unit, the first power supply unit and the second power supply unit, the control unit and the voltage detection unit are used to switch to the second power supply unit for power supply when the first power supply unit is abnormal, ensuring stable power supply of the load.
The stable and reliable power supply to the load is achieved, and the load power outage caused by the failure of the first power supply unit is avoided, the stable operation of the incinerator is ensured, and equipment losses are avoided.
