| Abstract: | It has been being a vital important topic of how to improve the safeguard abil-ity of overvoltage and overcurrent in SPC exchanges. On analyzing the causes of overvoltage and overcurrent emerging,this paper attaches importance to discuss the protection method and safeguard components on MDF (main dis-tribution frame)and SLC (subsriver line circuit);based upon the exploitation of the technical specifications in current use,it proposes a some fit approach and technical parameters. Through practice it shows to be reliable and meets the related specifications of the Ministry of Post and Telecommunication. |
