Abstract: A corrugated radiator for a transformer includes: a first flow path tube which receives insulating oil from a transformer main body; a second flow path tube through which insulating oil that finished the heat exchange with the outside flows into the transformer main body; and a corrugated fin block which has an inner space communicating with the first and second flow path tubes and receives the insulating oil, wherein the corrugated fin block is formed so that connecting portions connecting heat dissipation fins face each other to form a closed structure for circulating the insulating oil. According to the present technology, limitations due to an installation space of the radiator can be overcome and a plurality of heat dissipation fins can be effectively manufactured.

Abstract: A molded transformer is disclosed. The molded transformer includes a first body case, a second body case engaged with the first body case, an adhesive agent applied to the periphery of the engagement portion between the first and second body cases, coil layers provided inside the first and second body cases and spaced apart from each other at regular intervals, with coil support blocks interposed therebetween, an integral-type coil support engaged with the lower end portion of the second body case in order to support the coil layers, a lower support engaged with the integral-type coil support and seated on the ground, a height adjustment unit engaged with the lower surface of the integral-type coil support while penetrating the lower support in order to adjust the height of the integral-type coil support, and a tap changer provided on the side surfaces of the first and second body cases.

Abstract: Disclosed is a transformer capable of minimizing power loss during a transformation process by reducing stray load loss that occurs at a portion connecting low-voltage bushings. The transformer includes an enclosure disposed so as to surround power conversion equipment mounted therein, a pair of low-voltage bushings configured to transform the voltage of power received from a high-voltage bushing disposed on one side of the enclosure and to output the power, and a shielding member disposed near the pair of low-voltage bushings on the enclosure.

Abstract: Disclosed is a transformer condition-based risk management system and method in which risk based on the condition of a transformer is managed using online real-time condition monitoring data, offline periodically measured data and design data reflected in design and is reflected in maintenance decision-making so that optimal asset management is carried out.
