Generally, a distribution board is a device in which various kinds of circuit breakers such as a main power circuit breaker, an auxiliary power circuit breaker and an earth leakage breaker are installed on a base panel, and the breakers are electrically connected to each other. It is used to re-supply each element of the building and at the same time to open and close the power supply.
또한, 분전반에는 단자와 단자 사이를 접속하기 위하여 동판과 같은 두꺼운 판재로 이루어진 부스바(Bus bar)가 사용된다.In addition, a bus bar made of a thick plate material such as a copper plate is used for connecting terminals and terminals in the distribution board.
도 1은 종래 분전반의 일례를 도시한 도면이다. 도시된 바와 같이, 종래 분전반(10)은 베이스 패널 상에 주전원차단기(11)와, 주전원차단기(11)의 하측으로 각 전력을 인가하는 다수의 보조전원차단기(12)와, 전력을 차단하는 누전차단기(13), 단자대(14), 그리고 모선부스바(15), 자선부스바(16)를 포함한다. 1 is a diagram showing an example of a conventional distribution board. As shown in the drawings, a conventional distribution board 10 includes a main panel breaker 11 on a base panel, a plurality of auxiliary power breakers 12 for applying power to the lower side of the main breaker 11, A circuit breaker 13, a terminal block 14, a bus bar bar 15, and a charger bus bar 16.
