The Research And Design On Comprehensive Automatic System For Coal-mine

Since the Lv Jia Tuo coal mine puts into production, the secondary equipments of 35KV substation is still in the level of last century and can not meet the basic requirement of power supply system. It is necessary to reform the secondary equipments. The reformation adopt automatic technology, change the electromagnetic protection to digital protection, increase the sensitivity and accuracy, reform the outdated system to the new protection system which has the function of protection, measure, control and communication. The automatic system adopts the hierarchical structure and has powerful monitoring function, realize the"four remotes", at the same time, introduce web issue and wireless monitor system technology, the superintendent can skip the substation information through the local network and wireless mobile phone.
