압전 변압기를 적용한 단락 사고 보호 시스템 설계에 관한 연구 = A Study on The Design of a Short Circuit Protection System Applying Piezoelectric Transformer

다국어 초록 (Multilingual Abstract)

The main cause of electrical fire accident is an arc. In order to prevent such an accident, it is possible to reduce the probability of a fire accident due to an arc by reducing the fault current or shortening the detection time in the case of a short circuit fault. The existing arc prevention circuit is a technology to prevent arc accident by reducing the current of the accident, but this causes a problem that the load capacity is limited. In this paper, we studied the design of a system that can protect an accident by detecting a signal faster than the existing system using a piezoelectric transformer. For stable protection operation, a method for applying a logic circuit was studied, and through this, the performance and possibility of the system to protect against short circuit accidents were verified by applying it to the actual system.
