The Development Of The Electrolytic Nickel Special Controllable Depower Supply

Currently electrolytic nickel dedicated high-power rectifier dc power supply is used less, reliability is not high, not real-time monitoring system, not the device fault alarm, analyses the countermeasures to solve these problems, and on this basis, design a new type of DCS can be monitoring system of high power rectifier electrolytic nickel.This system mainly through on-load voltage regulating transformer for voltage regulation, can better meet the requirements of precision rectifier, and then determine the appropriate quick fuse, through the experiment of electrolytic nickel dedicated power supply provides experimental basis of choosing protection device. With this device to choose connection mode of arrest and connection style, so that we can improve the output efficiency and to avoid the rectifier cabinet temperature rise too quickly and rectifying system work stability has a certain significance to ascension.Electrolytic nickel special dc power rectifier device to trigger system in Shaxi province high-tech power electronics co., LTD. KCZ6-3 t3 thyristor trigger control board, realize the control of the commutating current. This trigger automatic fault diagnosis system can also be soft start and soft stop, in order to better meet all kinds of mutations, and appropriately increase the power supply reliability.In order to adapt to low voltage, high current electrolytic nickel production requirements, using multiple rectifier system, the advantages of this design is that the power factor of system state are obviously improved and pulsating coefficient was also significantly reduced. Thus system comprehensive performance is improved significantly. Select multiple rectifier circuit, say goodbye to the past 1 set of control mode, the pulse wave rectifier for parallel processing, the system of rectifying effect promotion effect is obvious. This monitoring system is the core part of the PLC control unit, the corresponding control signals are output via a standard communication interface, control of the DCS system to monitor supply by Zhejiang university. This system can be effective for signal acquisition and monitoring, data through the graphical output, and provides the table statements printing function.The electrolytic nickel special rectification power source is for Jilin electrolytic nickel industry factory production by electrolysis nickel board design of electrolytic dc power supply, significantly improves the work efficiency, the power system has high application promotion value.
