220KV Silicon Rectifying Device Application And Study In Lanzhou Liancheng Aluminum Industry Limited Company

Being an energy-intensive industry, various measures for reducing power consumption has been introduced in aluminum production, among which using large prebake cells and adopting advanced rectifying technique to stabilize pot current are two principal approaches. Currently, stabilized current technique is being used in soderberg pots to improve power supply status as well as lower power consumption.This paper with the technique reformation of the 220 KV power supply rectifying system for background, aim at an aging old and actual circumstance of the business enterprise aluminum electrolysis power supply system, put forward a total technique project which use GIS combination electric appliances and the third winding to adjust voltage rectifying transformer, complete the design and debug of the system.The thesis synopsis said an aluminum electrolysis power supply characteristics, present domestic research condition, pointing out the project research background and meaning;Elaborated the 220 KV silicon rectifying the constitute of the power supply system and work principle of each main parts and characteristics;Emphasized to study in the 220 KV rectifying system to power supply of the rectifying transformer design project to develop and make sure;Introduce the PLC of that system steady current and the microcomputer supervise and control system.Pass to the reformation that the rectifying power supply system, raise credibility of the power supply system, lowers single ton aluminum consuming of the electricity energy, reduce pollution of the environment, raise the production efficiency and economic performance of the business enterprise and promote the modern progress of the business enterprise. Consequently, have important meaning.
