Abstract
For frequent electromagnetic voltage transformer ( TV) fuses blowing accident in the distribution network , this paper analyzes that the main causes of the accident are ferro-resonance and low frequency nonlinear oscillation .It establishes a simulation model by ATP-EMTP, and makes the simulation analysis on the four main influence factors of TV fuses blowing which are the total length of bus feeder line , TV excitation characteristic , TV primary DC resistance and the single-phase grounding resistance .It gets the general rules that these factors have influence on TV primary current and the resonance state .It summarizes the advantages and disadvantages of several existing prevention meas-ures for TV fuses blowing , and compares of their harmonic elimination effect .关键词
