This paper aims at the prototype-making of the intelligent switchgear with arc fault diagnosis function required to prevent the electrical fire. The main control unit of the intelligent switchgear consists of a single-phase power management device and a arc fault diagnosis device. The prototype of the single-phase power management device and the prototype of the arc fault diagnosis device in this paper. In the device, the cooperation function with the arc fault diagnosis device is developed to transmit the cause of the electrical fire to the remote server system.

주택용 분전반내의 과부하 차단기(MCCB)나 누전차단기(ELCB)들은 전류 RMS 크기만을 가지고 고장전류를 인식하기 때문에 아크고장전류를 차단하지 못해, 수용가들은 전기화재로 인한 심각한 인명피해나 재산상의 손실을 자주 경험할 수 있다. 따라서 본 연구에서는 이러한 문제를 해소하기 위해 아크진단 기능을 가지는 지능형 분전반을 제안하고자 한다. 특히 여기에서는 아크고장 진단 기능을 고려한 지능형 분전반의 단상 전력관리 모듈 설계연구를 주 목적으로 한다.

현재 지능형 빌딩시스템에 도입되어 있는 스마트 분전반은 스마트 그리드 시스템과 연계하여 전력 수요를 분산시키는 기능 등 다양한 기능을 갖는다. 하지만 예측 불가능한 부하 종류와 운전 패턴에 따른 부하 불평형에 의해 발생하는 전력품질 저하, 전력기기 오작동 등에 능동적인 대처는 역부족이다. 따라서 본 논문에서는 지능형 분전반 운용 알고리즘을 통한 부하관리 시스템을 제안하여 부하 불평형에 따른 피해를 최소화하고자 한다.

We carry out a demonstration project to verify performance of a Home- Smart Cabinet Panel(H-SCP) at the child care facility. It is difficult to prevent an electrical disaster using a existing cabinet panel because electrical events are invisible and unforeseeable. So we construct a integrated information system with a Home-Smart Cabinet Panel(H-SCP) for management of low-voltage customers. The integrated information system with the H-SCP maintain the transmitted data from H-SCP, alert a electrical event to a administrator and show a state of customer health in real time respectively. A manager of electrical safety can prevent electrical disaster to maintain electrical facilities after analysis on the integrated information system.

In recent years, the many electric saving methods are studied because of difficulty of meeting the demand. The electric energy management such as monitoring of branch power consumption, demand control, metering, power quality monitoring, electric safety monitoring can make energy saving. The purpose of this paper is to develop a system which can provide the integrated management of various functions required for energy management by consumers. In this system all functions which were embodied into each devices are integrated into intelligent meter. The developed systems are tested and implemented by installing at consumer electric distribution panel.

In this paper, in order to monitor and manage an electrical risk factor like as leakage current, load current, and arc-fault, a real time monitoring and management system being operated in the ubiquitous environment was developed, and a plan of construction of an electrical safety grid using the system was proposed. For confirmation of usefulness and reliability of the proposed safety system and grid, the developed intelligent panels were applied to 28 Korean traditional houses in Jeonjoo city, and the grid including the panels was operated. If the proposed National Electrical Safety Grid is completely constructed in the houses of general electrical users, the Grid will have an effect on that a main manager on electrical safety transfers from management system by general people to real-time management system by expert. As a result, the electrical fires caused by an over-load, an arc-fault, and an earth-fault will be prevented.
