그 방법에 관한 것이다.It's about how.
최근 주택이나 아파트의 전기시설물에 의한 전기사고는 정전이나 화재, 감전 등으로 입주민들에게 크게는 재산이나 인명피해 등의 돌이킬 수 없는 피해를 가져다 줄 수 있다는 점에서 상당히 위험하다. 더구나 정전사고는 매년 전국적으로 발생Recently, electrical accidents caused by electrical facilities in houses or apartments are quite dangerous in that they can cause irreversible damage to residents, such as property damage or human life, due to power outages, fires, or electric shocks. Moreover, power outages occur nationwide every year.
하면서 입주민들에게 큰 불편을 주고 있는 사례로 꼽히고 있다.It is a case of great inconvenience to the residents while doing so.
한국전기공사협회(KECA)의 조사에 의하면, 전기시설물 사고유형은 지락, 기기소손, 부동작, 단락, 탄화, 용단, 파손, 붕괴등의 순으로 나타났으며, 특히 이 중에서도 주택에서 발생하는 전기사고는 단락이나 용단에 의한 경우가 가장 많았다.According to a survey by the Korea Electric Contractors Association (KECA), the types of electrical facility accidents appeared in the order of ground fault, device burnout, non-operation, short circuit, carbonization, fusing, damage, and collapse. Accidents were most often caused by short circuits or sudden cuts.
이러한 전기사고에 의한 피해발생을 방지하기 위하여 종래부터 각 가정에서 사용되어 온 전기 분전함은 배선용 차단기(NFB: No Fuse Breaker)와 누전 차단기(ELCB: Earth Leakage Circuit Breaker)와 같은 간단한 전기 차단기만을 다수구비한 것으로, 보통 정격값 이상의 지락전류나 누전전류, 또는 과전류를 검출하여 외부로부터의 전력공급을 차단하게 된다.In order to prevent damage caused by such electrical accidents, electric distribution boxes that have been used in each home conventionally are equipped with a number of simple electric circuit breakers such as a No Fuse Breaker (NFB) and an Earth Leakage Circuit Breaker (ELCB). As a result, the power supply from the outside is cut off by detecting ground fault current, leakage current, or overcurrent that is usually higher than the rated value.
상기 배선용 차단기는 개폐기구, 트립(Trip) 장치 등을 절연물 용기내에 일체로 조립한 것으로, 통전상태의 전로를 수동 또는 전기 조작에 의해 개폐 가능하며, 과부하 및 단락 등의 발생 시 자동적으로 전류를 차단하는 기능을 한다.The circuit breaker is a circuit breaker in which an opening/closing mechanism, a trip device, etc. are integrally assembled in an insulator container, and can open and close electric pathways in an energized state by manual or electrical manipulation, and automatically cuts off current in the event of overload or short circuit. function to

In particular, by inserting a zero-phase current transformer into the internal circuit and detecting the current difference of overhead lines due to leakage
써 경우에 따라 회로를 자동적으로 차단하여 사고를 방지하게 된다.In some cases, the circuit is automatically cut off to prevent accidents.

Therefore, as a consumer, the above
고의 발생을 인지하거나 미연에 방지할 수 있는 방법이 없어, 사고에 따른 위험도의 증가뿐만 아니라 사고의 재발우려가 상존하고 있는 실정이다.There is no way to recognize the intentional occurrence or to prevent it in advance, so not only the risk of accidents increases, but also the recurrence of accidents remains.
