Description

바리스터 교체형 서지보호기{SURGE PROTECTIVE DEVICE ENABLING REPLACEMENT OF VARISTOR}Varistor replaceable surge protector {SURGE PROTECTIVE DEVICE ENABLING REPLACEMENT OF VARISTOR}

본 발명은 서지보호기에 관한 것으로서, 보다 구체적으로는 서지보호기 내 특정 바리스터가 소손되었을 시에 해당 바리스터만을 용이하게 식별 및 교체하도록 하기 위한 바리스터 교체형 서지보호기에 관한 것이다.
The present invention relates to a surge protector, and more particularly, to a varistor replaceable surge protector for easily identifying and replacing only the varistor when a particular varistor in the surge protector is burned out.

최근의 디지털 제품 및 시스템은 마이크로프로세서의 속도증가, 집적회로(IC)의 집적도 증가 및 동작전압이 낮아짐에 따라 시스템과 기기들의 환경을 안정되게 유지하는 것이 매우 중요한 과제로 떠오르고 있다. 이렇게 고도의 안정성을 필요로 하는 곳에 서지전압의 유입, 노이즈 발생, 전압의 불안정성은 매우 큰 문제가 아닐 수 없다. 특히 서지전압의 유입은 단순히 시스템의 마비를 불러올 뿐만 아니라 전체 시스템을 파괴시켜 막대한 손실을 유발할 수 있음에 따라 서지전압으로부터 고가의 장비와 시스템을 보호하기 위해 서지보호기를 사용하는 것이 일반적이다.
In recent years, digital products and systems have become a very important task to keep the environment of systems and devices stable as the speed of microprocessors increases, the integration of integrated circuits (ICs), and the operating voltages decrease. The surge voltage, noise, and voltage instability are very big problems where high stability is required. In particular, it is common to use surge protectors to protect expensive equipment and systems from surge voltages because the influx of surge voltage not only causes paralysis of the system but can also destroy the whole system and cause huge loss.

그런데 통상 보호용량 이상의 서지가 서지보호기로 유입될 경우 보호기에 내장된 복수개의 바리스터가 한꺼번에 모두 소손되는 것은 아니고, 해당 서지가 유입된 모드, 즉 L-N, L-G, N-G 등 어느 한 모드에 연결된 바리스터만 소손되는 경우가 대부분인데, 종래 서지보호기의 경우 보호기 내부에 복수개의 바리스터들 각각이 보드에 일체로 고정된 구조를 가짐에 따라 특정 바리스터가 서지전압이나 기타이유로 훼손되었을 시에 고가의 부품인 바리스터가 장착된 그 보드 전체를 교체해야 하는 문제점이 있다.
However, when surges larger than the protective capacity are introduced into the surge protector, a plurality of varistors built into the protector are not all destroyed at once, but only the varistors connected to any one mode such as LN, LG, or NG is burned out. In the case of the conventional surge protector, a plurality of varistors have a structure in which a plurality of varistors are integrally fixed to the board, so that a varistor, which is an expensive component, is installed when a particular varistor is damaged by surge voltage or other reasons. There is a problem in that the whole board needs to be replaced.

In order to achieve the above object, the present invention, the varistor which is fixed to the metal oxide varistor (MOV) terminal and the signal extraction terminal in one package corresponding to the auxiliary PCB one-to-one; When the temperature fuse of any one of the terminals connected to each of the varistors is connected to each of the varistors and the varistors fixed to the auxiliary PCB to be connected to the terminals are disconnected, a signal of the signal output terminal is disconnected. And a main PCB provided with a display unit for displaying the varistor.
