<p>PURPOSE:To decrease the installation area of an apparatus and to decrease the loss in the apparatus so that the amount of the loss is smaller than the total loss of individual single units by using the main legs of an iron core as iron cores having gaps, utilizing windings commonly, and forming a unitary body with a transformer and a shunt reactor. CONSTITUTION:In a core type stationary electric apparatus, the main legs of the iron cores of a transformer are made to be iron cores 13 having gaps. A winding 2 is commonly used, and the transformer and a shunt reactor form a unitary body. For example, the main leg part of the iron core is made to be the iron core 13 having the gap. As the winding 2, a primary winding 2-2 and a tap winding 2-1 are arranged from the side of the iron core as in a transformer. Thus the same state wherein the shunt reactor is connected to an exciting side is provided. The inner part which is constituted in above described pattern is contained in an outer case 1 and further connected to a high voltage bushing 4 and a low voltage bushing 5. Thus the transformer and the shunt reactor are connected as a unitary body, and the area of installation can be reduced so that it is smaller than the area wherein individual single units are installed. The loss occurring in the apparatus can be made less. Therefore, cooling requirement can be reduced.</p> |
