Abstract : This text passes to compute the electromagnetism project of the transformer to the technique data that settle with main several why size, compute the function data to rise and compute the weight of the transformer with each part of tempreture with the shape size, make calculating the result match to the function index sign that settle.But after give or get an electric shock the protective design is to guarantee to protect the transformer and under the dangerous circumstance in short-circuit etc. does not damage, the safety circulate.Main a calculation for raising 6300 KVA/35KV cold electric power in breeze in immerse type in an oil transformer procedure in this text and its choose with a piece after the design of the electricity protection control circuit.
Keywords: High pressure transformer; Protect after the electricity; The electromagnetism scenario.
