paragraph division to work a telephone switchboard , designs the design including electric part and repeated part and secretly schemes against. In a part, want the analysis carrying out population on electric system and the transformer substation, choice ascertaining transformer substation electricity host connection form then, and carrying out systematic idle work compensation , secretly scheme against and electric equipment of short-circuit current here in process. Arrangement wanting to be to build a transformer substation to carry out the power distribution device and the general flat surface of electricity too in the queen who secretly schemes against concretely, designs , makes rationalization build a station. In repeated part, want the choice considering the way and short circuit point that way , system protecting run synthetically, the adjusting being in progress here on the basis secretly schemes against. Need to draw the relevance drawing sheet in the process of design , include more important drawing sheet such as host connection and grasp whose content.
