스마트 아크제거기 개발을 위한 개념 설계 및 실험적 입증에 대한 연구

Abstract

With safety being emphasized around the world, attempts are being made to eliminate arc-induced electrical accidents as they are the most proportion in existing electrical systems. As a result of reviewing the recent problems with arc elimination technology, it is necessary to develop a smart arc eliminator equipped with technology that can be selected depending on the size of over-current, and the reclose of available multiple times of the arc elimination while maintaining the high speed. In this paper, to propose the following conceptual design for smart arc eliminator that needs to be developed newly. The operating equipment part using Thomson coil was a conceptual design with developed in a cylindrical form for small-sized lightweights by the FEM program. The bumps structure in the operating contacts and the fixed contacts adopt the canted coil spring, etc. so that they can be endurance 20 times or more. The judgement part is embodied concept of malfunction prevention and large current sorting, and the subsequent Thompson coil actuator and return part to normal were designed with proper properties. Through this proposed conceptual design, developed to demonstrate the standards and design requirements of IEC, etc. by Official approval of the KOLAS Testing Institute. Also Smart arc eliminator were applied to the field to show effectiveness through case study results.
