PURPOSE: A power receiving integral transformer is provided to prevent short due to external factors by enhancing insulating rate and to easily perform a function of passive equipment by insulating a defected section opening and closing switch, a combined voltage current transformer, and a fuse. CONSTITUTION: A transformer unit(100) is installed in a space(S) formed in the inner side of a transformer case. The space of the transformer case is filled with insulating oil(300). A defected section opening and closing switch(210), a combined voltage current transformer(230), a fuse(250), and a vacuum interrupter(170) are installed in order to directly expose to the insulating oil. A gauge box, a controller, and a steering wheel(217) for manual operation are installed on the external side of the transformer case. The defected section opening and closing switch and the combined voltage current transformer are electrically insulated through an insulating unit(180).
