Abstract Mainly introduces a case of main transformer outage due to the transformer's lowering of the full insulation tube busbar defect, by analyzing protection actions,checking the equipment site once, analyzing the structure of tubular bus and counting equipment failure in the same type, know the main reason for the breakdown of the bus insulation is that the bus ends are wet, and manifested as a family defect. In order to ensure that there are no similar defects and reduce the losses caused by equipment failure, two plans of total insulation busbar transformation and operation and maintenance requirements for tubular busbar are presented.
