Abstract: A coil component includes a body having a first surface and a second surface opposing each other in a first direction and respectively having a recess formed therein, and a third surface and a fourth surface connecting the first surface and the second surface and opposing each other in a second direction, a coil including a coil portion disposed within the body and having a plurality of turns, a first lead-out portion disposed within the body and extending to the recess of the first surface of the body, and a second lead-out portion having at least a portion extending from an outermost turn of the coil portion to the recess of the second surface of the body, and first and second external electrodes disposed on the third surface of the body and extending to the recess to be connected to the first and second lead-out portions, respectively.

Abstract: Disclosed herein is a rupture prevention system, which increases a limit of the deformation of a transformer tank, thus primarily preventing a sudden rise in pressure, and which increases the number of rupture disc per unit area, thus preventing the rupture of the tank wherever the arc is generated in tank. The system includes a support part installed in the transformer tank and supporting a shielding plate so that it is not directly attached to the transformer tank. A plurality of rupture discs is mounted to pipes extending outwards from the transformer tank, and is ruptured when pressure in the transformer tank reaches a predetermined pressure level. A plurality of relief tanks is vertically installed at a position neighboring the transformer, and is coupled to the pipes. Further, an oil gauge is mounted at a lower position in each of the relief tanks, and generates a signal when the insulating oil flows into the relief tank.
