Abstract In this article, sunbber circuit of the load power cabinet in the GE Company’s LS2100e system is burned as an opportunity, introduced the overview and principle of the power cabinet, and analyzed the function of each Board in the power cabinet. Through the analysis of the current process variables when a fault occurred, the fault range locked. Combined the function of each Board in the power cabinet, in-depth analysis of the thyristor cell, confirmed the possible fault causes. Finally, put forward to the views and maintenance of LS2100e system.
