Description
technical field [0001] The invention belongs to the field of transformer fault simulation, in particular to a transformer winding radial deformation fault simulation platform. Background technique [0002] The power transformer is one of the most important large-scale equipment in the power system. The winding may be deformed to a certain extent under the action of strong mechanical force generated by transient pulse overvoltage or short-circuit impulse current during long-term service. The deformation of the winding may also be caused when the transformer is shipped from the factory to the site for installation and transportation. Although the slight deformation does not affect the stability of the transformer in the short term, it has a certain cumulative effect. Once it is deformed, the mechanical bearing capacity of the winding will decrease. The deepening of the degree will affect the normal operation of the transformer, and in severe cases will affect the safe and stab...
