| Abstract: | This document introduces domestic and overseas situation of insulation technology for asynchronous traction motors,talks about the theory of insulation construction of inverter fed motors and electricity,light,heat effect with the construction process of TiO 2 nanometer inorganic stuffing.Based on manufacture technology speciality of alterable frequency asynchronous traction motors and the theory of insulation system against corona,bringing forward a new concept of putting nanometer materials into stator coil insulation,through a reasonable way,inducting "enamel covered insulation"into asynchronous traction motors to better alterable frequency traction motors' ability against high frequency pulse corona. |
