본 발명은 내진안전성 확보를 위한 대용량 리튬폴리머 배터리 시스템용 전원모듈간의 전기적 연결구조에 관한 것으로, 특히 원전 전원공급장치용 스트링의 내부에 설치된 전원모듈간의 전기적 연결 부위가 외부 지진이나 진동에서도 안정적으로 유지될 수 있도록 한 내진안전성 확보를 위한 대용량 리튬폴리머 배터리 시스템용 전원모듈간의 전기적 연결구조에 관한 것이다.The present invention relates to an electrical connection structure between power modules for a large-capacity lithium polymer battery system for securing seismic safety. In particular, electrical connection parts between power modules installed inside a string for a nuclear power supply device are stably maintained even in external earthquakes or vibrations. It relates to an electrical connection structure between power modules for a large-capacity lithium polymer battery system to ensure seismic safety.

일반적으로 원전에서 비상전원을 공급하기 위한 시스템에서는 스트링의 내부에 다수의 전지모듈을 장착하도록 하며, 다수의 전지모듈은 전기적으로 단자 연결이 이루어진다. 이 경우, 지진으로 인해 스트링이 진동을 받게 될 경우, 그 내부 전지모듈간의 단자 연결부위도 함께 진동의 영향을 받게 되므로 단선이 발생되는 등 회로적으로 불안정하게 되므로, 이에 대한 해결방안이 강구되어야 한다.In general, in a system for supplying emergency power from a nuclear power plant, a plurality of battery modules are mounted inside a string, and a plurality of battery modules are electrically connected to terminals. In this case, if the string is vibrated due to an earthquake, the terminal connection part between the internal battery modules is also affected by the vibration, and thus the circuit becomes unstable, such as a disconnection, so a solution must be devised. .

본 발명의 배경이 되는 기술로는 한국 등록실용 등록번호 제20-0185395호로서, '플랙시블 단자'가 제안되어 있다. 이는 모선의 열에 의해 늘어나거나 수축되는 것을 방지하고, 전기기기등의 진동흡수, 치수수정 및 조정이 가능하며 지반침하에 따른 접속간극을 효율적으로 흡수 할 수 있도록 한 것으로, 절곡되어진 형태를 갖는 금속판으로 구성되어진 단자부와; 상기 단자부간에 배치되어진 도체부로 구성되어지되, 상기 단자부는 그 외주면이 주석 또는 은도금 되어진 금속판이 소정의 형태로 절곡되어 일정의 공간면적을 갖는 절곡면이 형성되고 상기 절곡면내에 다수개의 금속망이 적어도 2개이상 적층되어진 구조를 갖는 도체부의 양단이 수용되어진 상태에서 압착되도록 한 것을 특징으로 한다.As a background technology of the present invention, registration number 20-0185395 for the Korean registration office has been proposed, and a'flexible terminal' is proposed. This prevents the bus from being stretched or shrunk by the heat of the bus, allows vibration absorption, dimension correction, and adjustment of electric equipment, etc., and enables efficient absorption of the connection gap due to ground subsidence. It is a bent metal plate. A terminal portion configured; Consisting of a conductor portion disposed between the terminal portions, the terminal portion is a metal plate plated with tin or silver bent in a predetermined shape to form a bent surface having a predetermined spatial area, and a plurality of metal nets are formed within the bent surface. It is characterized in that it is pressed in a state in which both ends of a conductor portion having a structure in which two or more are stacked are accommodated.

그러나 상기 배경기술은 도체부에 금속망을 구성시켜야 하므로, 제작이 용이치 않으며, 금속망을 단자부에 전기적으로 연결 고정시키기도 어려운 문제가 있다.However, in the background art, since the metal net must be formed in the conductor part, it is not easy to manufacture, and it is difficult to electrically connect and fix the metal net to the terminal part.

아래에서 본 발명은 첨부된 도면에 제시된 실시 예를 참조하여 상세하게 설명이 되지만 제시된 실시 예는 본 발명의 명확한 이해를 위한 예시적인 것으로 본 발명은 이에 제한되지 않는다.In the following, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the disclosed embodiments are illustrative for a clear understanding of the present invention, and the present invention is not limited thereto.

본 발명은 도 1 및 도 2의 원전 전원공급장치용 스트링(100)내에 다수개로 수납된 전원모듈(10)을 상호 전기적으로 통전시키기 위해 도 3 내지 도 6과 같이 이웃한 전원모듈(10과 10)측 인쇄회로기판(16)에 각기 통전가능하게 밀착되어져 설치된 출력 버스바(17a,17b)와, 양단이 이웃한 출력 버스바(17a,17b)에 밀착되어 전기적으로 연결되어 있는 출력 버스바 연결단자(30)를 포함하여 구성된다.The present invention is a power supply module 10 and neighboring power modules 10 and 10 as shown in FIGS. 3 to 6 in order to electrically energize a plurality of power modules 10 accommodated in the string 100 for a nuclear power supply device of FIGS. 1 and 2. Output busbars 17a and 17b installed in close contact with each of the printed circuit board 16 on the side printed circuit board 16, and output busbars connected electrically connected at both ends by being in close contact with the adjacent output bus bars 17a and 17b It is configured to include the terminal 30.

출력 버스바(17a,17b)는 동으로 제작된 것으로 일정한 길이에 걸쳐 사각 단면을 갖는다. 출력 버스바(17a,17b)는 상면에 복수개 이상의 나사구멍(171)을 갖는다.The output busbars 17a and 17b are made of copper and have a rectangular cross section over a certain length. The output bus bars 17a and 17b have a plurality of screw holes 171 on the upper surface.

출력 버스바 연결단자(30)는 나사구멍(171)에 체결된 체결볼트(19)를 통해 출력 버스바(17a,17b)에 밀착되어져 전기적으로 연결된다. 출력 버스바 연결단자(30)는 지진 또는 진동으로 원전 전원공급장치용 스트링(100)내 전원모듈(10)의 위치 변동이 발생되더라도 안정적인 전원공급이 가능하도록 구성됨이 바람직하다. 예로, 도 7a 및 도 7b와 같이 출력 버스바 연결단자(30)는 직사각형태의 동 박판(301)이 다수개로 적층되어져 양단부가 열접합되어 접합부(301a)를 이루고 중앙구간은 비접합상태인 비접합부(301b)로 이루어지고, 동시에 그 접합부(301a)에 각기 동 박판(301)을 관통하는 볼트 삽입구멍(301c)이 형성되어 있도록 구성될 수 있다. 접합부(301a)는 예로 전기적 저항용접에 의해 이루어질 수 있다. 비접합부(301b)는 서로간에 접합이 안되어 있기 때문에 외부로부터 진동이 유입되더라도 유연하게 변형을 하면서 진동 흡수가 일어난다.The output bus bar connection terminal 30 is in close contact with the output bus bars 17a and 17b through a fastening bolt 19 fastened to the screw hole 171 to be electrically connected. The output bus bar connection terminal 30 is preferably configured to provide stable power even if the position of the power module 10 in the string 100 for a nuclear power supply device changes due to earthquake or vibration. For example, as shown in FIGS. 7A and 7B, the output bus bar connection terminal 30 is formed by stacking a plurality of rectangular copper thin plates 301 so that both ends are thermally bonded to form a junction 301a, and the central section is non-bonded. It is made of a joint portion 301b, and at the same time, the joint portion 301a may be configured such that a bolt insertion hole 301c penetrating each copper thin plate 301 is formed. The junction 301a may be formed by electrical resistance welding, for example. Since the non-joined portions 301b are not bonded to each other, even if vibrations are introduced from the outside, they are flexibly deformed and vibration absorption occurs.
