母线差动保护在矿井地面主变电所的应用

Application of Bus Differential Protection On the Ground Main Substation of Mine

母线短路发生的概率比输电线路低得多,一旦发生,后果非常严重。为了在矿井地面主变电所发生母线短路故障时,能够迅速切除故障,保护母线,减小事故影响,在矿区各矿地面主变电所,装设了专用母线保护。

The probability of a bus short circuit is much lower than that of a transmission line,once it happens,the consequence is very serious.In order to cut off the fault quickly,protect the bus bar and reduce the impact of the accident when the bus short circuit fault occurs on the ground main substation of the mine,the special bus protection can be installed in the main ground substation of the mine.
