    Abstract: The high voltage isolator and its supporting insulators are important components of high voltage system in the electric locomotive roof. This paper analyzed and optimized their electric field distribution, in favor of safe operation of electric locomotive. The grading ring was used in electric locomotive high-voltage system to establish three-dimension finite element model. This paper calculated the high voltage isolator before and after the grading rings configuration, insulator surface potential and electric field distribution, analyzed the impacts of mounting height, loop diameter and pipe diameter on the electric field optimization and gave the specific suggestion design parameters, which provides references for the application in electric locomotive high-voltage system.
    Key words: electric locomotive; high voltage isolator; insulator; snap grading ring; electric field optimization
